Biography
Toshiyuki Satou (佐藤利幸) is a Japanese key animator whose credits run from long-running shonen action to some of the biggest anime of the 2020s [1]. His filmography includes key animation on Chainsaw Man, Jujutsu Kaisen, Mob Psycho 100 across all three seasons, Kill la Kill, and One Punch Man, including its opening sequence [1]. Anime News Network's encyclopedia lists further credits on Attack on Titan, where he also worked as animation director, Frieren: Beyond Journey's End, and the film Promare, plus original character design work on the OVA Venus to Mamoru [1]. That combination of animation-direction responsibility on a flagship franchise and key animation across several of the decade's most talked-about action shows points to an in-demand specialist in modern battle animation. No birthdate, birthplace, or interview material is publicly documented for him [1].
