MARRIAGETOXIN has a main visual and trailer for Season 2, which is set to premiere in January 2027 with Studio BONES Film and director Motonobu Hori returning. Crunchyroll streams the anime, and the first season ran 13 episodes from April 7 to June 30, 2026.
MARRIAGETOXIN moved through its first season and straight into a second. The anime premiered on April 3, 2026, from studio bones film, based on the manga by Joumyaku and Mizuki Yoda that has run in Shonen Jump+ since 2022. Motonobu Hori directed, Kimiko Ueno handled series composition, and Kohei Tokuoka was character designer and chief animation director. Crunchyroll streams it, with new episodes weekly during the run.
By late May the adaptation had reached its Beast Tamer arc, starting with episode 8 on May 26, 2026. A key visual by Tokuoka accompanied the arc, and two cast members joined: Kazuyuki Okitsu as Toshiro Dogo and Ayaka Suwa as Byakko. The arc puts Hikaru Gero against a Beast Master to save Kimie Arashiyama, after earlier encounters with a Water Master and a Sound Master. The season finished with 13 episodes, running from April 7 to June 30, 2026.
At Anime Expo 2026, Hori and Bones Film producer Tatsuya Saito talked about adapting the manga, naming the characters and the series' ambiguous tone as the main draws and describing the difficulty of moving the manga's chaotic panel energy into animation. Hori appeared with voice actors Haruki Ishiya, who plays Gero, and Shion Wakayama, who plays Kinosaki, and said the enthusiastic overseas audience surprised him; he had thought the source material was very Japanese and did not expect it to travel so well.
Season 2 now has a main visual and a trailer, with a January 2027 premiere set. Studio BONES Film returns for animation and Hori is back as director, with Ueno on series composition and script and Tokuoka as character designer and chief animation director. The visual goes back to the large bridge where Gero saved Kinosaki in the first episode. Hori said production is moving smoothly and pointed to developments for Gero and Kinosaki, including a new potential marriage partner for Gero.
