𝑻𝒆𝒂, 𝑻𝒓𝒐𝒖𝒃𝒍𝒆, 𝒂𝒏𝒅 𝑻𝒂𝒓𝒕𝒔

Summary:

(𝑹𝒊𝒅𝒅𝒍𝒆 𝑹𝒐𝒔𝒆𝒉𝒆𝒂𝒓𝒕𝒔 𝒙 𝑴𝒂𝒍𝒆 𝑹𝒆𝒂𝒅𝒆𝒓) Being in a relationship with Riddle Rosehearts means memorizing the Queen of Hearts’ rules, attending perfectly-timed tea parties, and gently reminding your boyfriend that kissing you doesn’t violate dorm regulations.

Unfortunately, you’re also stuck with Ace, Deuce, Grim, and Yuuken, who generate more chaos than Heartslabyul can legally contain. From Ace bribing you to distract Riddle, to Deuce swearing he’s “changed this time,” to Grim being a trouble magnet, to Yuuken treating every inconvenience like a boss battle. You’re basically the dorm’s emotional support human.

Riddle tries his best to keep everything orderly.
You try your best to keep him calm.
And your four idiots try their best… to not burn the dorm down (they fail).

Welcome to Heartslabyul: where you juggle rulebooks, romance, and pure nonsense on a daily basis.

Notes:

In this story, this is only a Riddle x M! reader. So when it's over, I will make a second book where the M! reader is in a different relationship with the other characters, just like in the other books. ALSO, the dialogues and scenes in this story will be a mix of the manga and game since the events between them are different. But I do hope you guys enjoy this story!

(See the end of the work for more notes.)

Chapter 1

Summary:

“Royal Decree.”

 

Your voice struck the room like a commandment written into reality itself. The cards snapped together, forming a circle of red light that shot outward in a controlled burst. The spell wrapped around Grim like a glowing collar of authority, freezing him mid–fire-breath just as the flames were about to erupt.

Chapter Text

"How do I look?"

 

You turn around to face Riddle after you finished putting on the uniform for the entrance ceremony. Riddle stands a few feet away from you, arms crossed over his chest, looking you up and down before he approaches you. He lift his hands and fix your collar. Once he's finished, he takes a step back and smile "perfect as always. I believe it is time for us to go. The others are waiting."

 

You both walk together hand in hand and find Cater and Trey waiting for you outside. Cater sees you first and let out a low whistle "still can't get over the fact that you're in a relationship. Like people in my comments are still talking about you guys and liking the picture I uploaded." You raise an eyebrow "seriously? It's been a year since we started dating and people are still talking?" Trey chuckles as he fixes his glasses "well you two were the talk of the show ever since your relationship got out. No one could've expected that our strict housewarden is interest in being in a relationship, especially guys."

 

"Alright, that's enough" Riddle sends them a sharp look "let us go now, we must not lose more time before the ceremony ends." Without another word, you all begin to move.

 

You intertwine your fingers with your boyfriend and he glance at you with a small smile. You smile back, thinking that the ceremony will definitely go well.

"I'M GOING TO MISS MY BUS!"

 

Your eyes widen when you watch a guy bust open the door of his coffin, looking just as surprised as the rest of the students and headmage. The guy looks around mumbling to himself "where am I? I'm sure I was just at the bus stop..." He looks at the coffin he was in and freaks out. He steps out of it as you hear the students whispering to each other.

 

"He just came out of a coffin on his own."

 

"How does that even happen?"

 

"Oh honestly..." The headmage step up "you can't come through your gate unbidden, it's unheard of. What an impatient lad you must be." The guy turns around and bring up a... stick covered with a cloth. "Stay away from me!" The headmage paused and raise a hand "please calm down. I have not given you a reason to distrust me-" "huh? Just looking at you give away all kinds of red flag!"

 

You couldn't help but frown "is this guy unaware of what is happening here? Sure some students tend to forget a little bit after they come out of the gate but he seems to not know anything at all." You glance at Riddle and he seems irritated. This is not good.

 

"This whole thing- this place! Who are you guys?! What is going on here?!" You tuned out the conversation between this strange guy and lean a bit closer to Riddle "I understand that you are upset but please don't cause a scene, Riddle." You put your hand on his shoulder and he's very tense.

 

"It hasn't even started yet it's already getting heated." Azul stated in amusement. Kalim grins "this year off to entertaining start!" Riddle grits his teeth and clench his fists. Just like you said, he must not cause a scene. He doesn't want to end up humiliating himself.

 

While you're focused on calming down your boyfriend, you hear the sound of a window crashing and that made your eye twitch "what now?!" A grey and blue looking cat landed on the floor with a huge smirk. "What in the name of Sevens is that?!"

 

"I heard the whole thing! Do you have any idea how many people are dying to get into this school?! And you're willing to throw that chance away? Unbelievable! But if you insist... you can leave and I'll take your spot at this school!"

 

And the silence followed.

 

Everyone is just staring at the odd creature that had the audacity to break the window and disrupt the ceremony and make things worse.

 

The head mage, rightfully outraged, shouts at the cat "what? First, you barge into our ceremony and now you're talking nonsense?!" The cat completely ignores the head mage and cross it's arms "so whaddya say? The guy's completely speechless with gratitude!"

 

Speaking of the strange guy, he silently stares at the cat for a while before he speaks "the-... That tanuki is talking..." That sets the cat off "that's why you're stunned?! And I am not a tanuki!" He points a finger at himself "I am a monster who will one day become a mage! I am the illustrious Grim!"

 

A random student starts to laugh "pfft! Not a chance!" Another one agrees "yeah!  Save your jokes for your mountain friends, Tanuki!" Grim glares at them, getting more pissed at being mistaken for a tanuki "what was that?!" The students freeze and stop laughing "If that's how it's gonna be! Then i'll show you the special magic I've been  saving!" Grim rears his head and take a deep breath. Riddle realizing what's about to happen, shouted "everyone, get down!"

 

Next thing you know, you're on the floor with Riddle beside you, everyone is screaming and running around in terror whilst avoiding the blue flammes that are engulfing the room.

 

"AHHH! HOT!"

 

"MY ROBES!"

 

Meanwhile that Satan's pet is just grinning in accomplishment as if it had contributed to something "ya see that? That's what I can do! And there is a lot more where I came from!" It shoots more fire out of it's mouth and you immediately grab Riddle to get out of the way as you avoid bumping into any students. You glare at this thing and yelled "are you out of your mind?! Can't you see that you're hurting people?!" That creature just shrug it's shoulders "if they can't handle a little heat, then maybe they're not fit for becoming mages."

 

"Someone catch that blasted animal before it sets the entire school ablaze!" Crowley looks around in panic "this is not ideal! If we don't stop him then the school will be engulfed in the sea of flammes!" 

 

"AHHHH! Help! I'm on fire over here!" You see Kalim running around with fire on his butt. "Sevens have mercy, everything is burning and Jamil is not going to be happy when he hears about this..." You side stepped a student who was running towards you and yelled out "you gotta drop and roll, Kalim!" You immediately went to help him set the fire out.

 

Leona sigh, still sitting on the chair "can I go now? Or..." Vil place his hand on his hip with an amused smile "Oh? I thought you fancied yourself a hunter? Go and help yourself with that little morsel" The lion doesn't react and simply replies "eh, too much effort. Do it yourself."

 

"Allow me to handle this, Headmage Crowley." Azul stepped forward "If none of you are up to the task to catch a small animal then I will be responsible for that." You can hear Idia's voice coming from the floating tablet "WTG Azul! Racking up those participation credits!" Crowley yells and not even doing anything to control the situation as a headmage "I'm sorry, were my instructions unclear?!" Leona rolls his eyes "pretty sure you can handle catching a mangy weasel on your own headmage."

 

"How many times do I gotta say it?!" The creature shouted "I am not a weasel! I'm Grim, spellcaster extrordinaire!" He shot out more fireballs rapidly.

 

Riddle slowly walks towards Grim with a cold expression on his face "first, a student refusing to enroll, and now there is a monster running around?" He pulls something out "I will remove you from this school!" Grim notices him and gets tense "how dare you disrupt the solemn dignity of our orientation ceremony?!" Grim gets into a stance to shoot more fire "oh no you don't... You won't get in my way!"

 

After helping Kalim and making him calm down, you look away to see fire comming towards your boyfriend and that sight made your heart drop.

 

"Watch out!"

 

The strange guy from earlier jumps in and push Riddle out of the way, landing on the floor together but successfully avoiding getting burned.

 

"Oh boy..." You sweat drop as you go to see if they're okay. "Trey, he just..." Cater trail off as he continues to watch this shitty spectacle. "This is not good." Trey mumbled.

 

"Hey Kid! Are you okay?" The strange guy, who is on top of Riddle, asks. You blink once you heard what he refered to him. Your eyes trail to Riddle who seems immobile. Oh no- "Who do you think you're talking to?!" The guy flinched. But before he could say anything, Riddle pushed him "get off of me!"

 

"Riddle, calm down!" You immediately went to his side and helped him stand up "the guy doesn't mean any harm. He just wanted to help, okay?" You turn to the guy and offer him a smile "thank you for your help-" "you really don't know when to quit, do you?" the cat interrupted you, glowering.

 

The crackling roar of blue fire shot up the moment Grim puffed out his chest, his tiny paws raised like he was about to unleash the apocalypse in the middle of the orientation ceremony. Students screamed, papers flew, and the chandelier above gave a warning tremble, one good flame burst away from disaster.

 

You stepped forward, cape brushing the marble floor, crown insignia glinting with quiet authority. “Grim, enough.” You warned.

 

He didn’t listen. Of course he didn’t. His tail sparked like a lit fuse.

 

With a steady inhale, you raised your hand with your pen in it. Magic surged through you, heavy, royal, ancient. The air shifted. Cards etched with crimson sigils spiraled around your arm in a slow orbit, each one humming with the power of the King of Hearts.

 

“Royal Decree.”

 

Your voice struck the room like a commandment written into reality itself. The cards snapped together, forming a circle of red light that shot outward in a controlled burst. The spell wrapped around Grim like a glowing collar of authority, freezing him mid–fire-breath just as the flames were about to erupt.

 

Ten seconds.

 

Ten seconds of absolute obedience.

 

Grim’s eyes widened. “…Nyeh?”

 

"Riddle!" You called out.

 

Your boyfriend, already knowing what to do, nodded. His eyes flashed, magic surging like a blade drawn from its sheath.

 

“Off with your head!” Riddle declared, unleashing his unique brand of terrifyingly efficient Heartslabyul authority.

 

Your “Royal Decree” released its hold a heartbeat before Riddle’s spell struck, perfect timing, the kind only the King of Hearts could manage. Grim collapsed in a puff of smoke and offended yowling, his fire extinguished and his momentum crushed.

 

The crowd was silent.

 

Then the whispers began.

 

“W-was that the King and Queen of Hearts?”

 

“He commanded Grim like it was nothing!”

 

“He and Riddle... Did you see how coordinated that was?”

 

"So it's true that they are in a relationship!"

 

"What is this?!" Grim cries out "what did you do to me?!" He tries to take the collar off "Agh! I can't get it off!" Riddle cross his arms "stop fighting it, cat." Grim growled "this time, I'm gonna roast you both for real!"

 

. . .

 

Nothing happened.

 

"Huh? HUH?! My magic! I can't breath my fire!" He tries one more time. "Naturally." Riddle smirks at the thing "I sealed your magical ability with my magic spell."

 

"WHAT?!"

 

"Bravo, you've caught the beast!" Crowley clap his hands as he approaches the two of you "excellent work, Riddle Rosehearts, (name) (last name)! I expected nothing from The Housewarden of Heartslabyul and his lover!" You and Riddle blush at the last sentence then you cough into your hand "so, what do we do with this thing?" Crowley picks up the creature and says "right, as for this tanuki, I will remove it from the college grounds."

 

"Fr-MEOW?!" Grim struggles to escape from Crowley clutch. "I will never... ever... ever GIVE UP!" and that is the last thing we see from this creature the moment Crowley left.

 

You let out a sigh and rub your temple "man, that was a disaster..."

 

"So I guess this isn't a dream." You turn your head to see the guy is still on the floor "magic... I can't believe it really exists." A shadow looms over him and he looks up to see Riddle then points his pen directly into his face. "How dare you insult me like you did?" He doesn't give the guy any more time to speak as he says "that is tantamount to insulting The Queen of Hearts herself!" Your eyes widen "Riddle-" "that is a crime! Ergo... you will lose your head! Understand?!"

 

"Mr. Rosehearts and Mr. (last name)'s magic never fail to amuse me."

 

Azul chuckles. "Off With Your Head. A unique spell that places a magical collar around an opponant's neck, thus completely shutting off their magical power, and to be able to activate such an advanced spell with such a short incantation." Then he glances at you "Royal Decree. It is a powerful but highly temperamental form of command magic that traces its origins back to the original King of Hearts. The spell is rooted in ancient authority magic by using presence, tone, and magical pressure to force compliance. However, unlike Riddle’s precise, rule-based binding spells, (name) relies on pure dominance of will."

 

He leans back against his chair with a smile "and although his spell isn’t perfect yet, every use during chaos and training brings him one step closer to mastering the true power of the King of Hearts."

 

Leona smirks "ha! We're lucky that little red head is such a hard worker." Kalim smiles "with their magic combined, both of them really make such amazing power couple!" Vil raise an eyebrow "well, didn't they steal the spotlight?" The sound of Idia's voice comes through the tablet "good thing (name) is always with him to keep him calm. I don't like the way he loses his temper. It'd be best to keep staying away from him."
