A lonely otaku goes to the Middle Tennessee Anime Convention (MTAC) dressed as the infamous Symbol of Evil, All For One. However, he has his old mask and not his current mask. Upon arriving at the convention, a strange buyer offers to sell him All For One's current mask. He buys it without a second thought. After putting it on, he loses consciousness. He wakes up to find himself in a strange world with what appears to be magic. And he finds that he not only looks like All For One, but can use the exact same Quirk. What will he do with his new power?
