Oh, Great One (Bnha story)

What would happen if you saw something you were never meant to see? Something beyond comprehension, something you couldn't hope to understand, something that when you saw it drove you mad, something you would do anything to understand, to get the truth. This is what Izuku Midoriya saw on that faithful day, the day Izuku Midoriya changed and became mad.

What was it that he saw? what did it do to him?

(Eldritch style horror
