Kenji Ohtsuki and Zetsubou Shoujo-tachi
Artist
オオツキケンヂトゼツボウショウジョタチ
A special unit formed when Kenji Otsuki, vocalist of the rock bands Kinniku Shojo Tai and Tokusatsu, teamed up with the Zetsubou Shoujo, heroine voice cast of the anime Sayonara, Zetsubou-Sensei. With Ai Nonaka, Marina Inoue, Yu Kobayashi, and Ryoko Shintani on board, they sang OPs including Hito Toshite Jiku ga Bureteiru, Kuusou Rumba, and Ringo Mogire Beam!. Their distinctive world fuses Otsuki's poison and black humor with the cast's playful back-and-forth, capturing the source material's satirical spirit through music.
