Yuki Hayashi

Yuki Hayashi is a Japanese composer and arranger whose work spans television drama, anime, films, and sports performance. Before becoming a screen composer, he competed in rhythmic gymnastics and began writing music for floor routines. That background gave him practical experience matching sound to movement, timing, and audience response. He later moved into professional music production work and developed a recognizable approach that brings together orchestral forces, electronic textures, rock rhythms, piano, and emphatic percussion. His compositions are frequently built around immediately identifiable motifs and escalating arrangements, qualities that have served both competitive drama and large scale animation in Japan. Hayashi is especially associated with My Hero Academia, the television adaptation of Kohei Horikoshi’s manga about Izuku Midoriya’s progress from powerless admirer to hero trainee. His score gives the series musical material for heroism, school life, comic relief, and battles. “You Say Run,” a widely recognized cue from the score, has become a major point of reference for listeners beyond the program itself. Hayashi also composed the music for My Hero Academia: Two Heroes and My Hero Academia: Heroes Rising, theatrical films that extend the franchise’s stories beyond the television seasons. The latter includes “Might+U,” a vocal track used prominently. Another major anime assignment is Haikyu!!, the volleyball series based on Haruichi Furudate’s manga. Hayashi’s music for its television adaptation accompanies Shoyo Hinata’s attempt to become a player despite his short stature and Karasuno High’s return to competition. Percussive drive and rock influenced momentum suit rallies, training, and matches, while quieter cues make room for defeats and team relationships. His animation credits include Death Parade, set in a bar where recently dead people are judged through games; Kiznaiver, about students connected through an experimental pain sharing system; and Gundam Build Fighters, in which competitors battle using customized plastic Gunpla models. Hayashi has also worked on feature animation and long running franchises. He composed the score for One Piece Film Gold, the 2016 theatrical adventure in which the Straw Hat Pirates enter Gran Tesoro, an entertainment city run by Gild Tesoro. He later scored the 2020 television adaptation of Dragon Quest: The Adventure of Dai, based on Riku Sanjo and Koji Inada’s manga. Across these projects, his career has connected sports derived musical instincts with stories of competition, heroism, and spectacle. His credits reach audiences through original television broadcasts and theatrical franchise releases in Japan and abroad on multiple platforms today.
