MARRIAGETOXIN is a 13-episode anime that blends action, comedy, drama, and romance across its spring 2026 season. The series follows Hikaru Gero, an heir to a powerful family of poison masters living in the criminal underworld, who finds himself facing an unexpected crisis when his family demands he secure an heir to preserve their bloodline. Rather than accept his father's brutal methods, Hikaru takes matters into his own hands by recruiting Mei Kinosaki, a clever marriage swindler, to help him find a suitable bride. The arrangement puts two people from vastly different worlds into a tense partnership where survival and family duty collide with unexpected feelings.
The show appeals to viewers who enjoy mixing genres—those seeking genuine character dynamics alongside sharp comedic timing and high-stakes tension. MARRIAGETOXIN airs weekly throughout the spring 2026 season, delivering a complete story arc across its full run. The premise works well for anyone drawn to romance stories with real obstacles, characters working within dangerous social structures, or narratives where schemes and schemes meet authenticity.
For centuries, the deadly arts have been perfected by those known as the Masters. Among them, the Poison Masters of the Five Great Families hold the most fearsome power and influence. Hikaru Gero, heir to the Poison Masters’ Gero Family, has lived his entire life in the underworld, far removed from love or marriage. But when the Gero Family head decrees that Hikaru’s sister must bear an heir to preserve the bloodline—by force if necessary—Hikaru resolves to protect her at all costs. It is then that Hikaru encounters Mei Kinosaki, a brilliant marriage swindler who becomes the target of his latest job. Realizing that the only way of solving the family succession problem and protecting his sister is through marriage, Hikaru impulsively asks Mei for help in finding a bride.
