The anime "My Hero Academia," affectionately known as HeroAca, is based on the wildly popular manga by Kōhei Horikoshi, serialized in Weekly Shōnen Jump with over 100 million copies in circulation worldwide. The story is set in a world where roughly 80% of the population possesses a supernatural ability called a "Quirk," and it follows the growth, battles, and friendships of protagonist Izuku Midoriya and his classmates.

Episode 161 "The End of an Era, And The Beginning"
Synopsis:

Who should arrive at the battle between All Might and All For One (AFO) but Stain! For a moment, it seemed his "Quirk" of "Bloodcurdle" had sealed AFO's movements, but AFO had anticipated his arrival and prepared countermeasures. The battle takes a turn for the worse, pushing All Might into a desperate situation. Deku, sensing All Might's danger through his spiritual connection to One For All, cannot abandon the threat of the Tomura Shigaraki before him. The end of the "Symbol of Peace" draws near... It is then that someone stands up—!?
