Mission Personal Hell

Summary:

"what are we doing again.." Chuuya sighs, he knows he already asked twice but not once had he gotten a proper answer. "we're going to school!" the urge to punch that stupid fish got increasingly bigger. "no shit, I meant why"

Dazai just stared at him for a bit before a smile plastered on his face again "for the mission!" "what goddamn mission!!" "dont worry your little dog brain about it!" Chuuya grabbed him by his collar and pulled him down to his height. "give me a proper answer damn it!"

"ugh.. fine, you're so impatient Chibi" Chuuya didn't resist the urge to roll his eyes as Dazai started explaining the mission. this was going to be tiring is the only thing Chuuya could think.

Chapter 1: human or not?

Chapter Text

"what are we doing again.." Chuuya sighs, he knows he already asked twice but not once had he gotten a proper answer. "we're going to school!" the urge to punch that stupid fish got increasingly bigger. "no shit, I meant why"

Dazai just stared at him for a bit before a smile plastered on his face again "for the mission!" "what goddamn mission!!" "dont worry your little dog brain about it!" Chuuya grabbed him by his collar and pulled him down to his height. "give me a proper answer damn it!"

"ugh.. fine, you're so impatient Chibi" Chuuya didn't resist the urge to roll his eyes as Dazai started explaining the mission. this was going to be tiring is the only thing Chuuya could think.

 

as they walked together Chuuya looked around. he could see the thee shop he and ane-san always went to, and the dog centre, oh and an arcade. man he was going to miss this place, hopefully the mission wont take that long.

when he turned back to face Dazai, Dazai was staring at him. "what?" he asked, almost spitting the word out with anger and disgust. "just questioning how a person can be so ugly" "what did you just say!!?" Dazai turned away as if he didn't say anything and Chuuya got the extreme urge to rip Dazai's throat out. but he wouldn't.

soon they arrived at the border of Yokohama and honestly he was exhausted. why couldn't they take the car? or at least the fucking train? but noooo, they had to walk all the fucking way here! he stretched his arms a bit and turned back to Dazai as he spoke "so, whats the plan? how far we gonna go?" Dazai had a grin on his face, the menacing one that would send chills down anyones spins but Chuuya was used to it and didn't bat it an eye "do you think you could win a fight with a dragon?"

Chuuya just stared at Dazai dumbfounded "what the fuck are you talking about??" "has my little doggie not done his research?" "you didn't tell me I had to research anything!!" Dazai rolled his eyes. "there will be a certain dragon showing up any minute" "the fuck you mean a dragon?!!" a woman wearing a a dark red traditional qipao with a pattern at the bottom and neck walks through the border of Yokohama, she didn't do anything yet and seemed like your average traveler until you see long fringe over the right side of her face covering her eye and the weird bat wings on the back her head. some guy walk-up to her and they talked about something, probably the normal identification check. you know, not everyone can come in and leave Yokohama.
she made a kind bow at the man who waived her off. "looks like we found our Dragon~" Chuuya turned to Dazai, what was he on? that was clearly a woman. then again.. what the fuck was that thing on her head?

Dazai started walking after the women from a far enough distance and grabbed his phone, acting like he was playing a game. so were following her, huh? Chuuya followed along, going on his phone, he turned the corner at some point before coming back to where Dazai was, and Dazai turned a corner and came back later. they continued to switched like that, sometimes one of them was at a distance behind her and sometimes both of them. they had shared their locations with each other and by using this strategy it looked like they weren't together and weren't following her.
the woman kept asking random strangers questions and if Chuuya tried to hear what she was asking it sounded like she was asking about 'villains', criminal organisations, if there where any big attacks and the port mafia. Chuuya was honestly still thinking about the whole dragon thing. maybe Dazai had just been messing with him, trying to get in his head.. hopefully that was the case. it was way too early for this shit, then again its always to early for dazai's shit.

 

You: dazai, why are we following her

Mackerel: don’t worry about it! :p

You: what do I do if she asks me something?

Mackerel: tell her just enough ;)

You: your lucky I understand your bullshit

Mackerel: and don’t forget the plan! ;

You:the one you only told me half of?

Mackerel: you’ll play your job just fine! :0 Just follow me like a good dog! Just like you did with the following her thing!

You: whatever

 

Chuuya rolled his eyes, this guy was going to be the death of him. He was goddamn lucky he was cute. Chuuya sighed lost in his thoughts when a voice snapped him out of it.
“Ehm, hi little boy.” “Who you callin little!” Chuuya didn’t notice who it was till he looked up to see the woman?? Dragon?? “Ah- sorry, could I ask you a question” “oh, yeah, sure, go on” “do you know anything about the.. port mafia?” “Of course I do.” chuuya put his hand on his hip “recently they bought some container a few streets away, apparently theirs a bunch of illigal products there.” “What?! A-and your okay with that” “why can I do about it?” “Oh, yes, of course. Well thank you so much for telling me this.”
Chuuya whipped out his phone the second she left and texted dazai again.

You: she’s going to the container.

Mackerel: great! You know what to do! :>

You: no I fucking don’t! All you told me was to tell her about the container filled with illegal products!

Mackerel: and you did great! Now follow that dragoooon :p

You:what dragon?!?!

No reply? Ugh, whatever…

Dazai and Chuuya stood outside the container and heard a ton of rummaging inside. Dazai put his finger on Chuuya lip and winked. He could have just told him to be quiet but whatever.. they waited a few minutes and dazai made a hand signal and they stormed in.
Inside was some weird dragon things but it was wearing the lady’s clothes.. what the fuck was that? All the boxes where open and all their stuff was destroyed, this was going to cost millions. And he could just see the paperwork in front of him.
“Well, well, can’t have someone messing with our supplies now can we~” “give yourself over villain!” Chuuya had changed his hat and outfit slightly, seeing he was disguise when he talked to her so she wouldn’t recognise him.

he really wanted to get out for this stinky container, he'll make sure it doesn't take to long..

There where giant boxes everywhere, splinters all over the ground, destroyed goods etc etc. in the middle of it all stood a monstrous being. The being still had the red dress but for the rest there where nearly any similarities between the woman they just say and what was in front of them now. Chuuya sighed, he never imagined his day to go like this but what choice did he have? The small in here was horrific and there was mold on the edge of the container it was old, and stinky. One of the older port mafia containers, they used a new kind now, they didn’’t want there real containers getting destroyed.

“Be a good little dog and destroy her. Don't kill her yet tho~we need her’” thats the last thing he heard before going into battle. Chuuya hadn't had a good battle in a while, so it was rather nice to have a decent opponent. To bad it was over so fast. The dragon was back to its human form, or whatever the fuck that was. The woman was lying on the ground, chuuya had knocked her out.
“Tie her to a chair for me~’’ "I don't take orders from fishes!” “please~“ dazai put this fake puppy eyed smile with wide sparkling eyes on, chuuya knew it was fake. It wouldn't work. So then why the fuck was he doing it anyway?!

There he was walking next to dazai, the beaten up and tied up woman floating on a chair behind them. “Where are we going..” “to a pretty rooftop!” “why the fuck-” they had arrived at the rooftop and chuuya released the woman and chair from gravity and dazai put a his phone ready to film. “What are you doing now, you suicidal bastared?” “ugh, do i need to explain everything to you? I thought even dogs had a bit of brain, guess i was wrong..” “YOU-” “where going to sent a message to the HPSC! And then not send it to them!” “then whats the point of making the message…?” “so we can ‘leak’ it after a few months and everyone will think the HPSC was hiding their precious hero’s death from them! And so we plant distrust! When have my plans ever lead us astray, chibi?” chuuya couldn't argue with that, it was a pretty solid plan so he just turned away and scoffed. He wouldn't admit that dazai’s plans where good in a million years.
