Kazuki Ura plays Fuuta Okeya, Anna Nagase plays Kouko Ishigami, Eri Yukimura plays Rune, and Yuichi Nakamura plays East. Nagase also performs the ending theme "No Matter the World" (Koko ga Donna Sekai Demo), written for the series. Tatsuo Sato, who died in April 2026, directed the anime and wrote the series scripts at NAGOMI and EOTA; it is his final directorial work. Kentaro Mizuno served as assistant director and led completion of production. Satoru Fujimoto designs the characters, and TWIN ENGINE is producing.

  • Anna Nagase as Kouko Ishigami, the transfer student who tells Fuuta she will destroy his soul and break the cycle of reincarnation.
  • Eri Yukimura as Rune.
  • Yuichi Nakamura as East.

The story turns on a mark under the bandage on Fuuta's cheek. Kouko says it is a curse she carved into his face in a past life, and the series follows Fuuta through his earlier lives from the ancient past to the far future. REMOW sums up the premise as a grave sin committed by Fuuta's own soul.

Nagase's ending theme is her first solo vocal performance, according to Anime Corner. The manga ran in Young King Ours from May 2012 to 2016 and closed at six volumes; Crunchyroll began simultaneous publication in 2014, and Seven Seas Entertainment released it in English.
