Toshinori Yagi (八や木ぎ俊とし典のり Yagi Toshinori), also known as All Might (オールマイト Ōru Maito), is the former No. 1 Pro Hero who bore the title of the world's Symbol of Peace (平和の象徴 Heiwa no Shōchō). He taught Foundational Hero Studies at U.A. High School, and now serves as the school's vice principal eight years after the Final War. All Might was the eighth holder of the One For All Quirk after receiving it from Nana Shimura. He has since passed the torch onto Izuku Midoriya, whom he trained.
