Summary
Osamu Dazai took a dark, and lonely path in life. The man lived in the shadows until his final moments, at the age of 23— but what went through his head all those years? What led him to that decision?
Who is this man whom they address as 'boss'?
...And who was he before?
(SIDE-A will be written once this is over, as BEAST has an ending, unlike the main storyline.)

Lila Rossi. Thanks to her, not much has been going too well.
The difference in this timeline is how Marinette copes with it. (she doesn't)
Surely Dazai's influence will help her thouuughhh... right? (he probably caused this)
"Are you sure you want to commit a double suicide with me?" he briefly turned to look at his partner, before tilting his head away in favour of admiring the early morning view; the beach wasn't officially open yet.
The girl didn't even look at him as he spoke. She couldn't bring herself to. It took her a great deal of courage to bring herself this far, but if she gave him even a glance now, she knew her resolve would shatter.
"I swore I would join you one day, didn't I? That day when you promised you wouldn't do it unless I were there to join you."
OR!!
Marizai attempt a double suicide, some things can't go unignored.

Summary
"The bandaged boy.... who on earth is he?"
Dazai Osamu was sent on a mission to take preventative measures against the heroes and villains of the outside world. Mustafu, specifically. But that wasn't the mission he was set on, no. Dazai's mission? Wreak absolute chaos.
Or!!
An Mha x Bsd fic that starts off slow but will slowly dive into chaos.
Edit: chaos starts at chapter ten, everything goes downhill from there.

Summary
Mori claims his end of the deal from Fukuzawa, little does he know— Dazai has already sprung into action. Right then, the agency finds out about Dazai’s past sins, forcing him to flee. But Ranpo and a few others refuse to forget him along with the rest of the agency! They'll make sure to get him back! Dazai on the other hand, has other plans, starting an organization of his own. That slimy old doctor seems happy, probably since Dazai decided to form an alliance with the mafia.
OR
Dazai is on his own side now and literally everyone is fucked.

Summary
The events of Genshin ended (my headcannon of it at least, let me have the drama, thank you) and Celestia, as well as the nations of Teyvat have fallen after the last war.
However, somehow the god of anemo survived, waking up in an unfamiliar forest with no idea how long he has slept.
Meeting a grumpy hero, he has no choice but to find out what is even going on for now.Warning: I started writing this shortly before 4.0 so some plot stuff revealed after Fontaine might not fit or be described differently in the fic
basically: a crossover between MHA and Genshin with Venti as the main character that I cooked up instead of doing my homework (no, I am not 14)

Summary
For Aizawa, it seemed to be a normal day; after patrol, he was planning to go home and sleep for eighteen hours. That was until he saw the two bloodied teenagers sitting in an alleyway.
"What the hell."
(In which Dazai and Chuuya are sent into the world of heroes and villains. How will they hold in an environment where moral code is placed at such high esteem?)

Summary
Since the beginning of Quirks, Yokohama has announced independence from Japan and closed itself from the rest of the world.
To this day and age, no one knows what lies within the city of Yokohama—or that was what the public was made to believe. In reality, Yokohama has long fallen into the control of the world's largest criminal organization known as the Port Mafia.
Follow Class 1-A as their principal organized a field trip to Yokohama! In their short trip there, they must change their perspectives and learn exactly what it means to be justice and what it means to be villains.

Summary
Diona’s heel thumps against one leg of the bench, and she glances to meet his gaze. “…Where’s all this coming from?”
Venti blinks, and laughs, head dropping forward. “I… I’m not even sure. I guess there’s just something about being in this church that makes me want to… confess.”
Her pink brows furrow. “Confess to what?”
He sighs, soft and slow. “…I don’t even know.”
She leans back on the bench, propping her palms on the edge behind her and letting her head fall back. She stares beyond the tall organ pipes, up at the ornate ceiling of the grandiose cathedral. “…Venti?”
“Yeah?”
“Do you think this is how he wanted things to be?”
His breath grows shallow. “…Who?”
“Barbatos.”
“I… can’t say I know much about what he wanted.” He stares at his hands.
———————
One fateful night, Venti and Diona find themselves alone together in the Favonius Cathedral. An unlikely bond begins to form. Meanwhile, Rosaria spends the evening reconsidering her stance on the enigmatic bard’s claimed identity.
