Marriagetoxin streams on Crunchyroll — the one official home for this underworld action-comedy about a poison-wielding assassin who hires a marriage con artist to help him land a bride.

About

Deadly craft has been honed for generations by an elite few, and at the very top sit the poison-wielding clans — five ruling families whose command of toxins makes them the most feared names in a hidden criminal world. Hikaru Gero is the heir to one of those clans, raised from birth inside that shadow trade with zero exposure to anything as ordinary as romance. Trouble erupts when his family's elder rules that Hikaru's sister must produce a child to keep the bloodline going, with or without her consent — and Hikaru swears he'll shield her no matter the cost. The answer walks in as Mei Kinosaki: a gifted con artist who fleeces victims through phony engagements, and, as luck would have it, the very mark Hikaru has been sent to handle. Backed into a corner, he strikes a strange bargain — if a wedding is the one thing that can save his sister and settle who inherits the family, then he'll enlist the sharpest marriage swindler around to find him a bride of his own.

Seasons & Watch Order

Good news for newcomers — there's no back catalogue to binge first. Marriagetoxin is a standalone adaptation with no earlier anime seasons, so episode one is the front door. It's drawn from a manga, so there's source material waiting if you get hooked, but you don't need to read a single chapter to jump in.
