Yushiro x mha

So yeah he stays alive for centuries after the fight (not immune to the sun bc he wants a way to die so he doens't have to suffer if humanity goes extinct) with Chachamaru.

He studies all the latest drugs and doctor stuff, famously becomes known as 'The best doctor in the world'. He dont like all the fame so he goes to remote villages and stays as their doctor for a couple of decades bc its suspicious if he just don't age. Then maybe every 10 years he goes out to a university for a month to update his medical knowledge. A conspiracy theory comes up around this time cause he keeps appearing on cameras and reports by people for literal decades unchanged.

Insert quirks, he sees it on the news. He goes to Tokyo and becomes one of the lead scientists studying quirks, he's the head doctor other people are like biologists and chemists and stuff. Even though he does know everything about those other subjects too.

All for one makes first appearance, yushiro goes to witness the aftermath (he sneaks chachamaru around in a backpack with his invisibility paper). Chachamaru smells blood and alerts Yushiro who also notices the distinct trail and follows it. They come up on a room with two people standing at the doorway and inside is first one for all user. He knows about the resistance and marches past not caring "idc who you are, this person is injured and its my job to treat him"

So he goes back to resistance and becomes their main doctor, while still keeping up his public identity of researching against quirks, he's instead using them for all the latest medical knowledge and how to help one for all #1's condition.

Time skip like 30 years

one for all has been passed down to #3 cause other 2 died. Yushiro is finally being interviewed on why he isn't aging by the quirkist scientists, so he escapes and retreats to resistance. #3 asks about it and Yushiro explains what happened at his job, why?, Yushiro then reveals Chachamaru and explains demons he and and Chachamaru are the last 2 left.

Time skip to present day Masutafu

Insert yushiro reminiscing at his day job still known as Japan's best doctor. He's suddenly called to U.A. cause all the injuries from USJ and recovery girl cant heal some cause they got no energy and are critically injured. Yushiro shows up and gives them that medicine that can helps hashira in final battle (maybe it stops bleeding idk).

From then on he becomes class a's official doctor, cause recovery girl can only do so much. He hangs with recovery girl most of the day and they become close complaining about how often these damn kids hurt themselves.

He meets all for one in his last stand thingy before prison. All for one recognizes him from hundreds of years ago when he battled his brother, Yushiro was trying to stop the brother from the side shouting for him. All for one thinks yushiro got immortality quirk so he wants it.

Shigaraki he is targeting Yushiro for the 'quirk' cause he got all for one and all for one said that yushiro has the quirk he needs telepathically. They touch and all the heros panic, but of course it don't work. They win the fight and the villains run off, Yushiro now gotta explain wtf just happened.
