What if the Doom Slayer was in MHA? MHA X DOOM ETERNAL (Discontinued)

This story will tell what I think would happen if Doomguy landed in the My Hero Academia universe. ⚠️This will be 18+ with descriptions of violence, gore, rape, self-harm, abuse, suicidal thoughts⚠️, and romance. Remember, this is an AU, so none of the characters will act exactly how they do in their respective shows/games. U.A. will also be a college, so all the students will be 18 or over 18. This is also my first story, so don't go too hard on me.
