Izuku Fushiguro; A pact Unbroken.

This story brakes place in the current time line of MHA with Bits of JJK lore mixed in.

Izuku, is a direct descendent of Toji Zen'in. His Family was small, and luckily for him, his run in with a specific white-haired fellow didn't end in death. Though, it was near. After the event, Toji went off, and raised megumi like a good father, having acculated a decent bit of money bounty hunting. Somewhere along the line, Megumi had a kid.

This kid was a splitting image of his father, from the time of his birth, to the moment he was able to stand on two feet and swing a sword.

Izuku, also inherited what megumi didn't. Toji's Heavenly pact. which, unfortunately Took his quirk, and what little cursed energy he may have had. But, as it did with toji, it made all of his sense much, much stronger. Effectively turning him into the same monster that once was Toji Zen'in.
