Izuku Midoriya commits suicide, and discovers he has a quirk. This is convenient for no one, least of all Aizawa Shouta. It's your usual Izuku-with-a-ghost-quirk, until it just isn't.
Castiel is a human child now-(or is he becoming something more, as time goes on?)-alone in a new world full of quirks. Also, God is a huge Dadzawa fan, just FYI. You know how that goes.
Shinsou Hitoshi, Pre-UA, makes a friend and gets adopted. That's it, that's the fic.
A new business opens up in London. A new family moves into Private Drive. A new friend approaches a young Harry Potter on the playground. This changes some things.
Izuku has an unfortunate entanglement with a being from another dimension that eventually cumulates into Izuku making a decision he doesn't remember well enough to regret. Now, Dekiru is a ghost trying to make his way the best he can in a world that doesn't have a whole lot of them. (warning for suicide, stalking, gaslighting)
