Summary
The Moon Prince, Ka Zuigetsu, likes to call himself Jinshi.
No matter the skin he chooses to don, what lies underneath a face sculpted by the heavens is a man lacking self-worth, unable to be himself around his own family. Instead, he works himself down to his bone marrow, wanting nothing from the age of 13 but to be free from the bird cage his birth has locked him in.
A series of one-shots about the man underneath the celestial smile.

everything stays (right where you left it) by skuhy

Summary
Katsuki swivels towards the whirlpool, and there, in the middle is the dark silhouette of a man, static blurring the slant of his shoulders, the spikes of his hair, the red of his eyes-
(Wait.
Red-)
The whirlpool swirls, a final burst of static, and then implodes into a single point, black hole condensed. The ottomans stop floating, the desks stop vibrating, and everything sinks back down towards the vomit-coloured floor.
Bakugo Katsuki stands in front of them, eyes wide. His skin is painted with raised skin, eyes sallow. His mouth parts, and he blinks very quickly, in rapid succession. His hands curl and uncurl into fists.“Well,” he says. “That’s not fucking ideal.”
And then collapses onto said vomit-coloured floor.
[Or, due to time travel shenanigans, Bakugo Katsuki (2nd Year) meets Bakugo Katsuki (1st Year). Everyone has many questions, but- where did he get those brutal scars from? And why is he acting so...normal?]

Summary
It was odd, to think about how willing he was to die for the people he cared about. Worse, how willing he was to hurt other people just to protect them. He had ruined people’s lives, killed people, just because of his own selfishness. Just because he couldn’t bear to let the people he loved get hurt. Every time he thought about it, he felt like throwing up. He was just as bad as Connor when it came down to it.
Or: Shinichi isn't okay. He knows that there's something a little broken, but he's not on his own to pick up the pieces.

Summary
Kakashi has grown up knowing the agony that is the ability to see the dead. When Rin introduces him (rather insistently) to a tiny, brightly colored child who has the same curse, he decides to help her.
Now, if only he could stop hallucinating about Obito. And also get the Nidaime to stop giving him that judgmental look whenever he makes breakfast for Sakura.
