Marriage Toxin

A second season of the Marriage Toxin TV anime is confirmed for 2027, following an announcement in September 2026 that Motonobu Hori returns to direct at Bones Film with the same writing and music team. The first season, which premiered April 7, wrapped its initial arc in June 2026 and continues to draw merchandise and collaboration events.

Synthesized from 11 Yomimono stories · updated Sep 12

Marriage Toxin began as a TV anime adaptation of the manga by Joumyaku and Mizuki Yoda, serialized in Shonen Jump+ since 2022 and collected into twelve volumes, with Viz Media publishing the print edition in English. The first season premiered on April 7 and aired Tuesdays on Kansai TV and Fuji TV's Ka-Anival!! block, with Crunchyroll streaming and producing the English version. Motonobu Hori directed at Bones Film with production supervision by BONES, series composition by Kimiko Ueno, character designs by Kohei Tokuoka, and music by Taisei Iwasaki and Yuma Yamaguchi. The Japanese cast includes Haruki Ishiya as Hikaru Gero, Shion Wakayama as Mei Kinosaki, and Soma Saito as Genya Naruko, while the English dub features Ethan Gallardo as Hikaru, Brittney Karbowski as Mei, and Taylor Murphy as Akari, directed by Leeo George with scripts by Clayton Browning.

Episode reviews tracked the season as it moved between comedy and battle material. The premiere drew praise for its handling of Hikaru's queerness and Mei's layered gender presentation, and later episodes introduced Kimie of the Beast Clan as a bachelorette and a hitman targeting pro assassins. Episode 9 pushed further into absurdity with a Bird Master antagonist, while episode 12 closed the arc with Gero unlocking a new poison power by overdosing and Kimie rallying Beast Clan members against Dogo's chimera form. The finale announced a second season, and the close of June brought confirmation of a 2027 return.

Toys and events followed the broadcast. Alex Horn joined the English dub as Genya Naruko, a role announced in May 2026. A Share CAFE collaboration ran June 12 to 28, 2026, at three locations with a Rooftop theme. Banpresto placed a Mei Kinosaki figure in its GLITTER & GLAMOURS prize line on June 23, 2026. Bandai Namco Filmworks released Blu-ray Vol. 1 on August 26, covering episodes 1 through 7 with a bonus disc and side-story short, with Vol. 2 set for October 28. Animate's Retro Pop Fair runs October 23 to November 8, 2026.

In September 2026 the production confirmed a second season for 2027, with a promotional video and key visual. Kōhei Tokuoka returns as chief animation director and character designer, and the rest of the core team is unchanged. Season 2 was earlier slated for January 2027.

Marriage Toxin Episode 1 Review: An Assassin Comedy With a Queer Twist

Anime Feminist reviewed the premiere of Marriage Toxin, an anime about an elite assassin who decides to pursue marriage to avoid pressuring his lesbian sister into family obligations. The episode introduces Hikaru Hero, a skilled killer who also enjoys DIY candy kits and is deeply uncomfortable with romance. He meets Mei Kinosaki, a marriage swindler who becomes his ally in finding a partner. The review highlights the dynamic between Hikaru and Mei, noting that Mei's gender presentation is layered and that Hikaru's awkwardness around romance avoids transphobic jokes. The fight scenes are described as intense, and the setup positions Mei as the only person who might tolerate Hikaru's idiosyncrasies. The reviewer expresses strong investment in the story and anticipation for future episodes.
