Finding a wife was never a normal mission for an assassin, but that’s exactly Hikaru’s situation. Marriage Toxin confirmed its second season with a scheduled release for 2027, announced during the broadcast of the first season’s final episode on Wednesday. The team accompanied the news with a special announcement video.

The first season, which premiered on April 7, followed Hikaru Gero, heir to the Gero Family of Poison Masters, whose underworld life kept him completely distant from love or marriage. When the family head decrees that Hikaru’s sister must give birth to an heir to preserve the lineage, Hikaru decides to protect her and turns to Mei Kinosaki, a brilliant marriage scammer. With Mei as his advisor, the elite assassin embarks on the complicated mission of finding a wife, in a high-risk partnership between an assassin and a scammer that defines the series’ unique tone.

No details on the exact release date, cast, or production team for the second season have been announced yet. That information is expected in the coming months.

Production team

The first season was directed by Motonobu Hori at Bones Film, with production supervision by BONES. Kimiko Ueno handled the script and series composition, while Kohei Tokuoka was in charge of character design and chief animation direction. The opening “Kill or Kiss” was performed by Yurina Hirate, and the ending “Shake Na Baby” by AKASAKI.

Marriage Toxin is a manga by Jomyaku and Mizuki Yoda that began serialization in the Shonen Jump+ app in April 2022, with seventeen compiled volumes as of April 2026 and serialization still ongoing. The premise combines assassin thriller with romantic comedy in an unusual way: instead of direct romance, the central dynamic arises from a professional alliance between two people who are experts in opposite but equally dangerous worlds.

Do you think the dynamic between Hikaru and Mei has more potential as comedy or as thriller, or do you think the balance between both genres is what makes the series work?
