The production team behind Marriage Toxin has officially confirmed the series' return, dropping a new promotional video and key visual to tease the upcoming second season. The footage highlights the continued partnership between the elite poison master Hikaru Gero and his marriage consultant, the cunning swindler Mei Kinosaki, as they navigate the high-stakes world of romance and assassination.
Studio Bones is confirmed to return for the sequel, maintaining the core creative team from the first season. Director Motonobu Hori is back in the lead, supported by series composer Kimiko Ueno. The music will once again be handled by the duo of Taisei Iwasaki and Yuma Yamaguchi, while Kōhei Tokuoka returns to oversee character designs and chief animation direction.
While the first season debuted in April 2026 as part of Fuji TV’s 'Ka-Anival!!' block and streamed globally on Crunchyroll, the 2027 release window for this follow-up suggests a continued commitment to the series' high-production aesthetic. With the manga currently spanning 18 volumes, there is plenty of source material left to adapt as the duo continues their quest for the ultimate marriage.
Given the high-octane blend of action and romantic comedy, which specific arc from the manga are you most looking forward to seeing animated in the new season?
