Yoichi Shigaraki is the long-hidden younger brother of the villain All For One in My Hero Academia, and the very first person to carry the power known as One For All. The two brothers could not have started more differently: All For One was born with an extraordinarily strong Quirk, while Yoichi was thought to have none at all, a frail younger sibling overshadowed from birth.

All For One's cruelty defined much of Yoichi's early life. After their brother stole a baby's Quirk right in front of him, a shock that horrified Yoichi, Yoichi turned firmly against his own sibling. In an act that was part twisted affection and part cruelty, All For One then forced a stolen Quirk onto Yoichi that let him stockpile power inside his own body. Combined with a separate Quirk Yoichi already carried, one that could only transfer power to someone else and nothing more, the two abilities merged into what would eventually become One For All, the same power later passed down through generations of heroes, including Toshinori Yagi and Izuku Midoriya.

Though Yoichi himself lived and died generations before the series' main story, his decision to turn One For All against his brother's plans set the entire cycle of heroes and villains built around that power into motion, making him one of the most important characters readers never actually see in action.

My Hero Academia FINAL SEASON is the eighth and last TV season of the anime based on Kohei Horikoshi's superhero manga. It was made by Bones Film, with Kenji Nagasaki as chief director and Naomi Nakayama as director. It ran for 11 episodes in Japan, from October 4 to December 13, 2025. Crunchyroll streamed it outside Asia, with an English dub coming about two weeks after each episode. It adapts chapters 399 to 430 of the manga, from volume 40 to the end of volume 42. In this world, most people are born with a "Quirk," a special power that is different for each person. Some people use their Quirks to become professional heroes, and others use theirs to become villains. The story follows Izuku Midoriya, also called Deku. He was born with no power at all, but he dreamed of being a hero anyway. The great hero All Might saw his brave heart and passed on to him One For All, a power that has been handed from one person to the next for many years. Deku then joined U.A. High School, a school that trains young heroes. This season does not start fresh. It picks up right where Season 7 stopped, in the middle of a war between heroes and villains that spreads across Japan. Deku is now using the full strength of One For All. His main enemy is Tomura Shigaraki, a young man full of hate who carries the will of All For One, the oldest and most evil villain in the series. All For One has made himself young again. Standing against him is All Might, who has lost his own power. He fights wearing a strong armored suit, with only his courage and his tools. The heart of this season is the final fight for the future of hero society. Many characters that fans have followed for years get their last big moments. Katsuki Bakugo, Deku's childhood rival, is one of the most important of them. Their friendship, which began with bullying and slowly grew into respect, is one of the key stories in the whole show. Deku's fight with Shigaraki is also more than punches and powers. Deku wants to understand the person in front of him, not just beat him. The series talks about what it really means to be a hero. Is a hero someone who wins fights, or someone who saves people, even their enemies? The show also looks at how a society can fail people. Many villains became bad because nobody helped them when they were children. The final season brings these ideas together while still giving fans huge, colorful battles. There are many sad and emotional scenes too, as the war tests everyone. Because it is the end of a very long story, this season is best watched after the earlier seven seasons. It is fast, loud, and full of feeling. It is the ending that many fans waited about ten years to see on TV, since the first season aired in 2016. In Japan, the episodes aired on the channels ytv and NTV. A bonus special that adapts chapter 431 of the manga premiered later, on May 2, 2026.
