(third part of the Identity Quest storyline. SMT, UT, MHA, TOUHOU, Whatever crossover from the hell called my mind.) When Izuku collapsed after his classmates managed to catch up to him, all thought they just had to bring him back to UA and everything out be fine, but his overworked heart had other ideas. And then he was kidnapped. And then he returned a new man.
Please watch Warmly as Vaishnava Izuku, his wife and a few Gensokyen will make All For One and co. regret every decision they've made. For those who need comfort for the horrible final.
Izuku was left for dead on his eight birthday on the floor of a ruined shrine. the time was right, and the Wily gap youkai knew that he would change the world. but really, she was in it for the divine Chaos that would ensue.
