In a world of quirks, Izuku Midoriya heeds Katsuki Bakugo's advice and takes a swan dive.
In a world of Jujutsu and curses, Toji Fushiguro takes his own life to save his son.
Somehow, Izuku Midoriya is blessed and survives. As a consequence, His soul merges with a certain man restricted by the heavens.
Or
Izuku gains a complete Heavenly Restriction, along with the memories and experiences of a man who is very different yet somehow similar to him.
About five years ago, Midoriya was framed as a traitor of UA. Everyone believed it except for a select few. He was thrown in jail for two months and later found innocent, but the damage was done. He decided to leave UA, and Eri went with him because she hated them for what they did to him. No one has heard anything about them since.
