“	The Demon King did rule that fictional land. But, a hero of justice struggled against him, despite the horrible odds and saved the world. Don't you know? The villain always loses in the end.	„
	~ Yoichi vowing to stop his brother, All For One.

“	Yes. One For All emerged from the will to resist my brother, but... The moment you reached your hand out to me... was when One For All was truly born.	„
	~ Yoichi Shigaraki to his successor, Kudo.

Yoichi Shigaraki is one of the overarching protagonists of the My Hero Academia franchise. He is the late younger brother and arch-nemesis of All For One, as well as the first user of the One for All Quirk.

Despite his demise, he played a huge role in the series, as him transferring his quirk to his successor prevented his brother from getting his hand on it and creating a legacy of the One For All users to oppose against him. He would later become a major ally for the ninth and final user Izuku Midoriya in the fight against All For One.

In Japanese, Yoichi is voiced by Sōichirō Hoshi (who also voiced Goro Akechi in Persona 5, Sanada Yukimura in Sengoku Basara, and Ben Tennyson in Ben 10) and in English, he's voiced by Stephen Fu (who also voiced Naofumi Iwatani in The Rising of Shield Hero).

Biography[]

He was the frail younger brother of the Quirk-stealing villain All For One. Although they loved each other, Yoichi had a strong sense of justice and admonished his brother's evil ways. All For One, in an attempt to make Yoichi more powerful and join his side, forcibly gave him a Quirk that would allow him to stockpile power.

Unbeknownst to even himself, Yoichi had a Quirk that allowed him to transfer it to another, which was fused with the stockpiling Quirk, creating a Quirk called "One For All" that could be passed onto others and grew in power with each generation. Rather than joining his brother, Yoichi fled from his captivity with two men named Kudo and Bruce, his eventual death caused by a fit of jealous rage from All For One. The blood splattered on Kudo that day began the chain of inheritance that would create the One For All users, cultivated slowly over time so it could amass enough power to take down All For One.

Over a century later, Yoichi began communing with the ninth user of One For All Izuku Midoriya despite having long been dead by that point through his awakened vestige self. He told Midoriya the untold history of One For All as well as the history of All For One who was still operating Japan's criminal element from behind-the-scenes, eventually guiding the boy in full as he prepared to take down Tomura Shigaraki, All For One, and the League of Villains' forces as a whole.

Personality[]

Yoichi is considered the polar opposite of his older brother; he was physically weak, sickly and was believed to be Quirkless, but was known for having a strong sense of justice and righteousness. He stood up to his brother, seeing through how he would manipulate others to join him and admonished him for all the deaths he caused. Despite being physically weak and sickly, he still made attempts to stop All For One from committing his atrocities, and continued to oppose his brother's megalomania, even when imprisoned.

Apart from this, he is quite friendly with everyone else, such as those who would be his successors and inherit One For All. This especially applies to Izuku Midoriya, whom he had a lot of respect for due to his strong conviction to help others, including his enemies, and would end up repeatedly supporting him as a result.
