God of Calamity

Y/N aka Yaboku is a hero killer for the League of Villains. (He works for whoever gives him an offering but the Heroes do not know that) He is told to kill All Might, by All for One, and he almost succeeds until he decides to surrender, why? What is he planning? What will happen?
This is a one-shot unless you ask.

I don't own Noragami or MHA
