Tsukasa was peacefully sleeping that morning, until someone began budging her...

And yet she slept through all that, until her sister took out her pacifier.

Tsukasa was a shy but sweet 17 year old girl. She was a part of a large family as well, living with her parents and 3 siblings, one of which being her twin, Kagami. She wasn't really very intelligent though, often scoring below average on tests, which led her to be overshadowed by her twin, Kagami, who always aced every single test she took. But this left Tsukasa wondering...

She weirdly started having some strange desires. More...desires to forget her worries, and take on a form where she didn't have any of them. And, well, she did take on that form one day, spending most of her allowance on a pack of diapers and a pacifier, and after trying it, she became addicted to the feeling, and started finding new ways to relieve her old self and feel small and cute again.

However, this unfortunately turned onto her, as she started playing her childhood show, Mahou Shoujo Powder Power, too loud in the night, attracting the attention of Kagami. She was of course terrified at first, but after some explaining to Kagami, she appeared to understand her regression as a way to relieve her memories. Kagami even offered to spend the night with Tsukasa, and overtime, she found herself finding Tsukasa more and more cute, and started to treat her as if she was her baby sister and not her twin. Tsukasa absolutely adored this feeling, so she let it stay. This led to the present day, where Kagami was using her new method to wake up Tsukasa, who was a heavy sleeper.

'Mm...oh? Aah, I fell asleep regressed again!'

'Hey, not too loud, Tsukasa! I'm just waking you up...'

'O-oh, sorry. Is there anything going on?'

'We were planning to meet up with Konata, remember?'

'Oh! Sorry, I forgot...'

'You really need to stop fooling around at times...'

'Don't worry, I'll get ready quick!'

'It's not for another hour...'

'Then why did you wake me up now?'

'You usually take a while to get ready...anyway, I'll be in the living room.'

Kagami then left, much to the confusion of Tsukasa.

Konata Izumi, who Tsukasa called Kona-chan, was a member of Tsukasa and Kagami's friend group. She was the stereotypical otaku, being very lazy and tomboyish, and of course, obsessed with anime. Often she would change up her entire personality just because of an anime she watched. In reality though, she was just silly at times, and did like Tsukasa, even if she was a bit blunt about Kagami and Tsukasa's flaws at times. 

Tsukasa sighed at those thoughts, before quickly kicking the pack of diapers under the bed, taking off her own before hand and putting it in her drawer. Luckily no one looked there too often. She got a regular pair of underwear on after that, and then got dressed in a jumper as well as a pair of dungarees, which appeared to be her casual outfit despite it looking like what a three year old would wear at times. Yet another time Tsukasa was letting out her inner child. Tsukasa then did her hair quickly, before walking out to get some breakfast. 

Kagami was waiting in the living room by the kitchen for her.

'I thought you'd take a lot longer than that...'

'I didn't really understand what you meant by that either...'

'Is it just because I pointed it out...?' Kagami thought. Tsukasa was like that at times.

After Tsukasa had made and ate breakfast, she proceeded to spend the next hour watching the news with Kagami, who weirdly just loved to watch that. That was until Kagami checked the time.

'Oh, we should go now.' She said, quickly getting her things together.

Tsukasa nodded, getting her shoes on, and going to say goodbye to her mother, before she and Kagami went out together. 

It was a long walk, but they made it to the city centre, where Konata was waiting by the anime store.

'Oh, Kona-chan!'

'Hey there. Oh? You're wearing that outfit again...'

'H-huh? Is it weird or something?'

'I always see you wear that outfit. Whys that?'

'It makes me feel the most comfortable, plus I don't really like wearing dresses when it's cold out...'

'That makes sense, I suppose, but why not another colour? I think pink would suit you well.'

'Please don't take fashion advice from her, Tsukasa...' Kagami said. She wasn't exactly too found of Konata's antics at times.

'What about your outfit, Kagami?'

'Huh? What do you mean?'

'I mean, you're the one wearing pink and yellow. You often wear shorts too, whys that?'

'They're comfy and easy to wear. There's not much more I can say...'

'I don't think yellow is your colour. Let me think, hmm...I usually see Kagami with horns, dressed in all black and dark red...ah, like a demon!'

'What is that meant to mean?!' Kagami said, clearly annoyed. 

Tsukasa giggled slightly at Konata's antics.

'Okay, first is the anime store.' Konata said, seemingly leading the way.

Tsukasa nodded, and Kagami just followed Konata in. 

Later...

Kagami had walked out with nothing. Tsukasa had walked out with a cute light hearted manga. Konata walked out with an entire volume.

'Um...Kona-chan, how much did you spend?'

'¥1700.'

'Wha-? Um, and how much do you have left?'

'...¥300.'

'You already spent all your money on manga?!' Kagami said, frustrated.

'At least it'll make my otou-san happy, he's been searching for this for a while.'

'Oh, he's an otaku too, isn't he?'

'Yep.'

'Those girls look around our age though...' Kagami commented.

'We don't talk about that.' Konata said, face seemingly gone dark and depressed.

'Eh...?' Tsukasa thought, confused.

After a while, they ended up in the arcade. 

Later...

Tsukasa did walk out with a cute teddy bear, but the other girls didn't get anything in return.

'How much do you have now, Kagamin?' Konata asked.

'Ughh...¥500...' 

'You were too confident, and my streaks gone up to 56!'

'You have a streak for how many times you beat Kagami, Kona-chan?'

'Of course. It's an easy way to get on her nerves, after all.'

'I'll beat you one day, just see!'

Konata simply gave Kagami her casual cat smile.

'Thank you for giving me your tickets, Kona-chan. I managed to get this teddy bear with it.'

'It's cute, isn't it?' Konata said, poking its stomach.

'It really is...hehe, it might be useful for later.'

'...you still sleep with stuffed animals, Tsukasa-chan?'

Tsukasa blushed a deep shade of red, while Kagami attempted to defend her.

'So what if she does? She's just trying to sleep more peacefully.'

'Peacefully? Hm, they do say a girl's sleep affects her mood...'

'Shut up!' Kagami said, annoyed too much with Konata at this point.

'But we're out of money now, aren't we...?'

'You have ¥200, Tsukasa-chan.'

'You have none though...'

'Hm...why don't I go to your place then? We can rest there.'

'Oh, of course! Mother should be fine with it.'

'Perfect, I can play a few more rounds with Kagami then.'

'Konata, I'm at my limit...' Kagami said, shaking.

'Well, lead the way then. We'll be at your place in no time.' Konata said.

One long walk later, and the three eventually ended up at the Hiiragi residence. After talking with Mrs Hiiragi, she let Konata stay for a bit, and they eventually ended up in Tsukasa's room since Tsukasa wanted to sort out her plushies.

'You have a lot of stuffed animals, Tsukasa-chan.' Konata said, looking around.

'They at least make the room like nicer...'

'I don't mind you sleeping with stuffed animals anyway.' Konata said, reading the manga she just bought.

'What manga is that called, Kona-chan?'

'Azumanga Daioh. It's about a group of four girls who go on adventures.'

'That's awfully generic...' Kagami said. Ironically.

'I like all genres though. Manga is great nonetheless.' Konata responded, continually reading, before looking around Tsukasa's room again.

'Say, Tsukasa-chan, what's in that drawer?'

'Eh?!' Tsukasa said, thrown completely off guard by the question. That's where she kept her diaper and pacifier from last night...

'Ohh...it's your underwear drawer, isn't it?'

'Why is it your business?!' Kagami asked, but Konata ignored her.

'Um...yeah, it is!' said Tsukasa, thinking it would chase her off.

'Hmm...curiosity is getting the better of me, you know...'

'Don't look in there!' Tsukasa shouted, blushing terribly. She had definitely blown the cover now.

'Why are you so secretive? Is it a love letter or something?'

'N-no, it's nothing like tha-'

And just like that, Konata pulled open the drawer, to find...

...

'...'

'...Tsukasa-chan, what is this...?'

...

Tsukasa took a step back, face red with embarrassment, but also fear. Konata had just found it...her..comfort items. 

'It's none of your business what it is!' Kagami said, frustrated at Konata for not listening.

Konata ignored her, and closely started inspecting the material, rubbing her hand along it. It made a slight crinkle sound as she did so. 

'Hm...that's a diaper, isn't it? But what for?'

Tsukasa sat down, still shaking. Konata waited for a response, just quietly staring at her.

'Like I said, it's none of your business. Just put it back.' Kagami said.

'Kagami, I'm talking to Tsukasa-chan.' Konata said. She was surprisingly calm about the situation.

Tsukasa took a deep breath, and finally recomposed herself.

'O-oh...they're just for bedwetting. It's a problem I have...' Tsukasa replied.

Konata put back on her casual cat smile. 'Okay, I was just wondering.'

Konata luckily had bought Tsukasa's lie, and went to put them back...only to make another discovery.

'...what?' Konata said, just looking confused as hell. 'What's this for then?'

Tsukasa blushed further, knowing that her lie had been caught. 

Kagami sighed. 'Tsukasa, we should just tell her.'

'E-eh?! But-?'

'I'll make sure she doesn't pull off any moves.'

'I'm right here, you know...' Konata said.

Kagami sat beside Tsukasa, who was now staring at the floor. Meanwhile, Konata hopped up onto Tsukasa's bed, to the left of her.

'So, what's this about then?'

'W-well...I don't have any problems, I just...use them often.'

'Why?'

'...I...enjoy it?'

'Ohh...I see how it is.'

'W-wha? No, it's not like that at all!'

'Hm? What do you mean, Tsukasa?'

Tsukasa blushed deeply, being caught in 4K.

'You're the one that suggested it.' Kagami said.

'I didn't mean it like that at all, Kona-chan! Well...have you heard of something called regression?'

'Maybe on a 4Chan post before. Why?'

'It's like...you get into the headspace of a younger version of you.'

Konata looked confused at Tsukasa's wording, but seemingly got the hint.

'I've think I've seen that in a manga before. Is it like a transformation?'

'Stop saying stupid things...' Kagami said.

'N-no, it's like a mental thing! You're mentally a little girl, but you're physically big...'

'I see...'

Konata stared up at Tsukasa, her cat smile coming back yet again.

'So can I trigger it like this?' Konata said, as she suddenly put her hand up, and pushed the pacifier she was holding into Tsukasa's mouth, as she panicked slightly. 

'Stop! It's none of your business!' Kagami said, seemingly for the fifteenth time.

Tsukasa looked worried, but didn't object to having her pacifier in.

'You do look cute with that in, Tsukasa-chan.'

'That's my sister, you know!'

'So are you still twins when you're a younger a-'

'Just shut up, okay?!' Kagami shouted, furious at Konata's antics. She clearly wasn't taking any of this seriously, and needed to shut her up in one way. However, once the room had gone completely silent, the room was now filled with the sound of Tsukasa suckling on her pacifier, and she turned red yet again.

'See? She likes it!'

Tsukasa nodded sheepishly.

'Will you take this seriously!' Kagami said, still shouting.

'Well...then I'm completely serious when I say that I support you, Tsukasa-chan.'

Kagami's face then changed at Konata's words.

'I'm not weirded out by it or anything. If there's one thing I learned online, people enjoy things, and that's okay most of the time, because they're not harming anyone else by doing it.'

Tsukasa still had her paci in, but seemingly forgot that as she smiled and said: 'Um, tank woo-' before turning completely red.

Konata decided to play in on this.

'Aww, aren't you the cutest!'

Kagami just watched. She wasn't happy about someone who wasn't her taking care of Tsukasa, but Tsukasa was clearly happy.

Tsukasa giggled through it, seemingly getting into Konata's praise.

'You've always been the cute one, but I thought you couldn't get any cuter until now!'

She giggled yet again, before taking out her pacifier and saying a shy 'Thank you, Kona-chan.'

'So...normally we'd play video games, but I'd prefer this. Tsukasa-chan, should we do it now?'

'Eh?!' Tsukasa said. She definitely didn't expect that, but the concept terrified her. What if her mother walked in?!

'It's probably not the best time to do that...' Tsukasa said.

'When have your parents ever walked in on us, Tsukasa-chan?'

Tsukasa thought about it. It had never happened before.

'U-um...but I wouldn't get into the right headspace easily...'

'Then simple, I'll be your mommy.'

'Don't call yourself that!' Kagami said, kind of feeling left out.

'Mm...but then I'd have to be Kagamin's mommy too, wouldn't I?'

'She's the baby here, not me...' Kagami responded.

'Well, that's for the best anyway.' Konata said, smirking at Kagami.

'Finally, I agree with you on something...'

'Um...well, Kagami's never offered that kind of role before.'

'God forbid.' Konata responded.

'I'm not sure how to feel...maybe just this once...?'

'Okay!' Konata said, hopping down. She was a lot shorter than Tsukasa, but she would do her role one way or another.

'Let me help you with getting it on, then!' she said, as without warning, she started undoing her dungarees.

'E-eh?! Konata, not-'

'How else am I meant to do it?'

'That's just weird!' Kagami said.

'And you're calling a mommy changing their baby weird? You're the weirdo here, Kagami.' Konata responded.

Kagami had no comeback for that. So, Konata began to undress Tsukasa, soon stripping her down to just her underwear.

'W-was taking off the shirt necessary?!' Tsukasa asked shakily.

'We'll get you in something way more comfortable.' Konata smiled, reaching for her underwear, as Tsukasa suddenly flinched.

'I-I can't do it, I'm sorry...'

'Hm? I'm just doing my role...'

'B-but...I can't let you see...!'

'Look, I can do it if you want.' Kagami spoke up.

'E-eh?'

'You're my sister. Would you be more comfortable doing it if I was handling that kind of stuff?'

Tsukasa thought about it, but Konata responded.

'Sure, you can do it. I don't know how to change someone anyway.' 

She then hopped off the bed as Tsukasa stared at her.

Kagami walked over with no hesitation. 'Let's make this quick, you're going to get cold.'

Tsukasa relaxed herself upon seeing someone she basically knew since birth, and was more relaxed when Kagami completely stripped her. Luckily Konata wasn't tall enough to see without it being too obvious. She then got out the diaper which Konata put back, and spoke up.

'It'll be easier if you put your legs up.'

Tsukasa complied with it, and Kagami slid it underneath her. With a straight face the entire time, she did up all the tapes together, leaving Tsukasa diapered. She then got out some cute clothes Tsukasa often wore, and dressed Tsukasa up in them in order to make her feel comfortable.

'How does it feel?' Konata asked.

'I-It felt weird at first, but I think I can get comfortable here.'

'Then could I help you get into little space then?' Kagami asked, and Tsukasa nodded.

Tsukasa moved to the center of the bed, as Kagami and Konata followed, and Konata gave her the teddy bear from earlier while Kagami gently pushed in her pacifier.

'There we go, now just relax.'

As the two cuddled up with her, Tsukasa felt a sense of comfort from the two. This was her best friend and her twin sister cuddling her, after all. She was in a position where she just felt so tiny and cute, in a safe space, never to be hurt...

...

After a while, Tsukasa opened her eyes, and both Konata and Kagami smiled.

'It worked!' Konata said, hugging Tsukasa, much to the baby's surprise.

'Don't do that, she'll get frightened.' Kagami said, quickly getting out a few things.

'Well, I wonder how this new side of hers would be at video games...'

'Don't take advantage of her regression to win in video games!'

'Eh, worth a shot. So what can we even do with her?'

'It was your idea to be her mommy, wasn't it? So, you make the calls.'

'Uh...' 

Konata thought back on her childhood. She remembered that her dad often showed her a lot of old animes and she watched them as a kid...maybe Tsukasa would like the same?

'Ah, so we give her anime!'

'Do you know anything about parenting?!'

The oblivious Tsukasa looked at the other two. It was kind of confusing for her to have two caregivers at the same time, but she wasn't sure which one was her mommy. So, she just sat there, cuddling up with her teddy bear, suckling on her pacifier.

'Well, I'll do it like how my sister used to play with me.' Kagami said.

Kagami brought out a plushie that was in Tsukasa's room, and held it up in front of her.

'See this? What animal is it?'

Tsukasa looked at her, clearly having no idea what was going on.

'It's a cute bear, see?'

Despite Kagami's small smile, she was having trouble understanding what Kagami meant. However, she held up her own bear to her.

Kagami was now lost on what to do, but awkwardly, made the two bears hug each other. Tsukasa seemed surprised at this, but understood the wholesome gesture, and laughed as a result.

'Jeez, don't try to outmatch me.'

'It's called sisterly love, Konata.'

Konata's face suddenly went emotionless.

'...Konata?'

'Sorry, I just had too many disturbing thoughts.'

(Side note: Like the prequel, Kagami and Tsukasa aren't incestuous, Konata is just attracted to both of them.)

Kagami stared at her for a few seconds, before composing herself again.

'So, are you ready to be with her?'

'Okay...'

'Then go ahead.'

Konata simply got closer to Tsukasa, with her typical cat smile. However, Tsukasa started crawling closer towards her.

'Huh...?'

Tsukasa gave an innocent smile to Konata...and history repeated itself. The same feelings Kagami felt about Tsukasa's regression was also coming to Konata...sort of a desire to protect, but also dying of her cuteness. Konata smiled at her.

'You're really cute, you kno-!'

Tsukasa pulled her into a tight hug. Oddly enough, something was drawing her towards Konata...within just a moment of Konata being with her, she felt like she was important to her, despite being around Kagami for longer. But her little self trusted Konata, and wanted her to love her too.

'...aww...' Konata couldn't help but say that, smiling as she did. She gently stroked Tsukasa hair as she did so. Is this what it was like being a mommy...?

'She definitely likes you then.'

'I've only had little Tsukasa for 2 minutes but if anything happened to her I would kill everyone in the room and then myself.'

'...what?'

'Oh, nothing.'

Tsukasa continued cuddling Konata, until she broke the hug and presented Konata with the teddy bear.

'Oh...? Do you want to play?'

Tsukasa nodded. She seemingly did understand Konata, but just her saying 'play'. 

Konata then pulled out an anime figure. 'Then let's play.'

'Wait, not that one!' Kagami said, but both Konata and Tsukasa ignored her speech. It was of a buff male with a black hat, with some purple text beside him in Japanese. 

'How are you meant to have a wholesome roleplay with that...?'

'Watch me. Kagami, get the bear from earlier.'

Konata seemingly had an idea, and while this was questionable to Kagami at most, she just complied with what Konata wanted and got out the bear.

'Good.' Konata then took it, and put it besides the figure.

She then smiled. 'Are you going to save this bear?'

Tsukasa, remembering an episode of Mahou Shojo Powder Power, quickly moved her bear forward.

Here comes the part where Konata could involve her own interests into it.

'Oh...you're approaching me? Instead of running away, you're coming closer?'

Tsukasa nodded, a determined look on her face, even if it was concealed by a pacifier. 

'Oh ho ho! Then come as close as you like!'

Tsukasa immediately swooped in, and knocked the anime figure over in one punch. Konata didn't want it to be over that quickly though, so she got it right back up.

'Star Platinum is the Ultimate Stand! It will save me!'

It wasn't actually the figure who said that quote, but Konata was just going along with it.

Kagami then decided to contribute. 'Save me, Mahou Teddy!'

Tsukasa nodded, and with her teddy, had a clever plan. She rushed up to the anime figure from behind, and knocked it over then. Konata then got her figure up again, but with some more dialogue.

'I must say...you are good!'

Tsukasa still wasn't done, as she crushed the figure with the teddy bear, and Konata made a fake noise of pain.

Tsukasa giggled, and as Kagami started clapping, she did too.

'Curse you, Mahou Teddy...I'll get you next time!' Konata said, putting the figure back in the bag.

'Yay, you saved me!' Kagami said.

Tsukasa felt proud of herself, and started hugging the teddy bear. Everyone was actually having a lot of fun with Konata's idea, even if it was of a reference they didn't get.

'Hey, Kagami, could you get us some snacks?' Konata asked, throwing off the clapping completely. Kagami did seem a bit annoyed at Konata's interruption, but nodded nonetheless.

'Sure, I'll get some. You two stay here.'

After a while of Konata and Tsukasa just waiting there, Kagami eventually came back, with some cookies and milk.

'This is all we had...'

'That's fine!' Konata said, clearly really happy with it, as she immediately started eating. However, Tsukasa was eyeing it with a smile, assuming it was for her.

'...um, Kagamin?'

'What is it?'

'Tsukasa's staring at the milk...'

She definitely was...however, she couldn't just give it to her from the glass. They would make a mess on Tsukasa's bed otherwise.

'Have you ever fed her, Kagamin?'

'No, we usually did it late at night so I never brought any snacks.'

'Jeez, so do we just not feed our baby?'

'We can give her little cookie crumbs. She'll know how to chew.'

'How are you so sure?'

'It's just instinct.'

Kagami seemed pretty confident in herself, so Konata obliged, and started tearing off little pieces of cookie.

'Here, Tsukasa.'

Tsukasa, surprised, took out her pacifier to eat. Then, Konata placed a tiny crumb in her mouth. Tsukasa chewed a bit, and then her face immediately lit up, and smiled from what she just tasted.

'See? She likes it!'

'Konata...she's beside you now.'

Like a dog who was just given a treat, Tsukasa was now beside her, smiling with her adorable eyes, begging for more cookie crumbs. And with no hesitation, Konata fed her a few more. Face lit up like a Jack O Lantern.

'She's so cute, isn't she?'

'Maybe if you dip one in milk you can give more to her.'

'Definitely worth trying!' Konata tore off a big piece, and dunked it in milk, completely absorbing it. She then fed it to Tsukasa, as she smiled the biggest smile before giggling and clapping.

'She loves it, see? I'll give her more!'

Overtime, they eventually fed Tsukasa more and more cookies. By the time they were finished, Tsukasa had two whole cookies.

'Eh, there's still plenty for everyone.' Konata said, as Kagami took her first and last one.

After eating it, Kagami suddenly got up from the bed, and began to leave.

'Hm? Where are you going?'

'I'm just going to the bathroom, one second.'

Konata nodded, and Kagami left the room, leaving Konata and Tsukasa alone again.

'Hm...well, without Kagami to tease, there's still one girl in this room I can tease, is there?'

Tsukasa looked at her, curious.

'Well...tickle tickle tickle!'

Suddenly, Konata began tickling Tsukasa, much to her surprise. Tsukasa began uncontrollably laughing at the feeling. Konata was having a lot of fun doing it, so she kept going on. She just loved the sound of hearing Tsukasa laugh, and this was one of the few ways she could get to do it. However, with every action comes consequences, and...

Sssssss...

The sudden sound of water trickling came out of nowhere, much to Konata's surprise. She immediately stopped tickling Tsukasa, and looked around...before realising it was coming from Tsukasa. Her eyes suddenly went wide with what she was hearing...she was actually using her diaper. She definitely didn't plan for this, and definitely not in the room while Kagami wasn't in. 

After the noise stopped, Tsukasa had an uncomfortable look on her face, but Konata smiled at her.

'Oh, I didn't expect that...but it's okay, it's perfectly normal for your age.'

Tsukasa's uncomfortable expression disappeared after that, seemingly understanding Konata's words. She was a baby now, so it was perfectly normal for her to use it, despite the fact it was completely unexpected for her to do it.

'Eh, I know you're not going to flinch if mommy's doing it, so-'

Konata suddenly stopped herself. Did she just call herself Tsukasa's mommy...? It really had developed to this point, but at this point Konata had accepted it. She was Tsukasa's mommy now.  

As such, she would act like one. She lay Tsukasa down and inserted her pacifier in to soothe her. Then Konata took her shorts off, before getting to the tricky part. She didn't exactly have a lot to work with here, but she would make it work. She then took her wet diaper off before putting it in the empty drawer Tsukasa was carrying earlier. Using a box of tissues she had just bought, she wiped it away. Next time she would definitely have to bring more supplies. Konata then got down, looking for another, before noticing the pack of diapers under the bed, and got them out. She then took one out, and like Kagami did before her, she slid it underneath Tsukasa, and did the straps up, before putting the shorts back on. Tsukasa smiled at no longer having the uncomfortable feeling.

'There we go, Tsukasa-chan.' She said, gently giving her headpats.

That's when Kagami walked back in, and sat down on the bed. Immediately, she started to pick up on something.

'Hey, what's that smell?'

'I tickled her and she wet herself.' Konata bluntly said.

'What?!'

'Don't worry, I managed to change her.'

'Don't do that next time! This might be problematic...jeez, what if mother finds it...?'

'You'll be fine, Kagamin. I'll take care of it.' Konata said.

'How?'

'I'll just take the bag with me. Also, um, you should probably get an air freshener...'

Kagami sighed. 'I'll get that now.'

However, their conversation was suddenly interrupted by Tsukasa's yawn.

'Oh, are you tired now, baby?' 

Tsukasa nodded, not really too worn out, but just wanting to go to sleep.

'Okay, let mommy tuck you in then.'

Kagami's face turned to shock upon Konata calling herself Tsukasa's mommy unironically, but quickly shook it off, and smiled.

'I guess it's better like that. Your father probably wants you home soon, right?'

'Oh, I have to be home by eight. I forgot.'

'You could've mentioned that earlier.'

Konata 'carried'- well, it was more like dragged- Tsukasa to the bed, but gently and without startling her. Then she moved Tsukasa's head near the pillow, making sure her neck was straight. She put the blanket over her then, tucking her into bed. After that, Tsukasa closed her eyes, and Konata smiled at the sight.

'Sweet dreams~' Konata said, and kissed her forehead.

Kagami definitely wasn't expecting this level of wholesomeness from Konata...she didn't trust Konata at first to help out with Tsukasa's regression, but Konata astounded her in an entirely different way. She actually treated Tsukasa like she was a baby, and leaned in to help her. Not to mention she conjured up a whole roleplay scene just to make Tsukasa happy. Sure, she did mess up slightly when tickling her, but she sorted it all out herself. Kagami definitely knew she wasn't mommy material at all, but maybe Konata could be Tsukasa's mommy, and she could be Tsukasa's older sister still. It was the ideal second family for her.

Konata then began to prepare everything up, including her anime stuff and the wet bag.

'That was fun...'

'Well, I wasn't expecting you of all people to be a good mother...'

'Eh...it's going to be awkward when I have to explain to my otou-san why I'm buying baby products for my friend though.'

'W-wha-? Don't worry about that.'

'I will. I can't let her love you more after all.'

Kagami turned away. 'It's not like this is a competition or anything...'

Konata began to leave, but turned to Kagami with her casual cat smile before. 

'Thanks for helping out.'

Really Kagami should've been the one saying that, but Kagami just nodded and let her leave. 

Konata walked out, and as soon as she left outside, she immediately put the wet bag in the recycling, and went on her way home.

Well...Konata definitely didn't expect that to happen. In no world would she have thought one of her best friends to be an age regressor. But oddly enough...she did really enjoy it. Tsukasa did look really cute as one, especially when she hugged Konata tightly. She definitely saw the appeal in it after that. She just wanted everything to make Tsukasa happy, and she thought she definitely succeeded in that department. From when Tsukasa hugged her, to when Tsukasa beat the anime figure, to Konata feeding her...it all just brought together, to make all three of the girls so happy. Overtime, she knew she could develop in order to make Tsukasa even happier...hopefully.
