MHA Yokai Watch

This took place a few months after Izuku was told he couldn't be a Hero by his idol, saving his former best friend, being chewed out by the Heroes...and later being told once more what he was doing, what he was trying to do...was a foolish thing and that he should just give up...and it was said by his idol again and infront of everyone who saw this and they just laughed at the young boy, who felt his world crushed.

And in those months all he could do was stay in his room, ignoring the need to eat a few days and worrying his mother.

But then on one day, one simple decision will change his life from a quirkless nobody...to someone who makes his own path and doesn't listen to those who caused the world to be corrupted.
