Osamu runs away from home, runs into a man who smiled seemingly at nothing and decides to figure him out.
or
Osamu Dazai runs into an off duty Eraserhead and taken in like a stray kitten.
NOTE: Writing style changes, I started taking the story seriously so I started writing seriously.
+Tell me if I missed any tags, I redid them but I am not sure I got them all... :D
+There will be a tag along fic in Chuuya’s POV that will have extra details that might not be in this fic. (After getting to certain point I will be working exclusively on the Chuuya fic until I get to the same point in time as this fic. Then each will be posted as I come up with stuff…)

Damn it Dazai! You were supposed to slay the dragon, not lay the dragon!!!!
Dazai is a knight sent to slay Chuuya, but that isn't quite what happens... I will trigger warn you; Chuuya is tall when he's a dragon. Yes, I know, very unnatural and upsetting. Don't worry, he's still a chibi when he is in human form.- Language:

Summary
Summary (I forgot to add one...) : Atsushi Nakajima has never known the outside world, his perspective shaped only by the orphanage director and his teachings on God, and his misinformed views of a world that had hurt him. Lilya grew up on the outside, she knew heroes and quirks, and she knew villains. Her life was different from Atsushi's but they were friends. When Lilya develops a quirk Atsushi is forced to rethink his views. Was his friend really evil or was he just misguided.
When Atsushi develops a quirk of his own he is faced with the wrath of the headmaster. A false angel tries to steal his power and his life. And he is finally given peace with a new family. But the effects remain, his mind is a shattered mirror of identities each with their own thoughts and needs. Amongst them is a God who saw its own reflection in the boy, lending him power and strength unimaginable.
or
A normal abused orphan is possessed by an ancient god and believes its a quirk.
(Abilities are powers lent to humans by Gods who see themselves in humans... IDK man.)

"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.

Summary
There are far too many conspiracies for Aizawa to keep up with; he's just a man yearning for a childhood dream. He knows what to do: acquire information and connections from Yokohama while keeping his suicidal students safe. Not a very hard job, only if All Might wouldn't encourage the aforementioned suicidal students into more suicidal situations, just as simple ideas for dates.
Yokohama's darkness isn't gentle, but it is quiet. Once it swallows someone, it leaves no bones behind.

Summary
If Dazai is anything, he is a perseverer. A stupidly incredible one, at that. Big deal if he passed out after taking a nasty blow. Mori will patch him up and he’ll bounce back in a few days like this was all but a ‘whoops, how silly of me!’ moment.
But he realized after he called for back-up and took Dazai’s pulse like the practice demanded that… no.
He’d… overestimated Dazai’s alleged perseverance.
Or: Dazai refuses to breathe. Chuuya has plenty of say in that matter.
Now available as a PODFIC!!! (Read by the Author)

Summary
When the door opened it revealed a view chuuya could never imagine, even if he tried.
It was Dazai, the Osamu Dazai, the demon prodigy, the one who usually would break into his house, knocking loudly on his door.
He never saw Dazai like this.
He looked terrified, with tears in his eyes, his eyes weren't sad, they were filled with anger. Which in his opinion made it look like a horror image. And to add more, his clothes were with blood on them.
The bandages in his right eye weren't there anymore.
When chuuya opened his mouth to say something but then Dazai grabbed him and hugged him...
'What the fuck'
