# Where to Watch Marriagetoxin

**Marriagetoxin has not premiered yet, so its planned run of 13 TV episodes is not ready to binge. Crunchyroll is the only official streaming service named for the series ahead of its 2026 release. The hook gives a poison trained heir a problem that none of his deadly education can solve: he must find a bride to spare his sister from their family's demands. A marriage swindler becomes his guide, bringing the practiced logic of a con into a search that he has to take seriously. That contrast is the best reason to keep Marriagetoxin on your list. It should suit viewers who like dangerous professionals pushed into awkward personal territory, but no one can fairly judge the finished anime before it airs. Bones Film is producing the adaptation.**

## Where to Watch

Crunchyroll is the sole official service listed for Marriagetoxin. Since the series is upcoming, its 13 episodes are expected with the 2026 release rather than as a complete season available now.

## Synopsis

A young heir from a family built around poisons knows how to handle lethal work, yet he has no idea how to pursue a relationship. When responsibility for continuing the family line threatens to fall on his sister, he chooses to seek a wife and take that burden himself. He turns to a marriage swindler whose livelihood depends on understanding desire and manipulating expectations. Their arrangement sends him into courtship with expert coaching, while the danger tied to his family never slips far from view. Marriagetoxin builds its premise around the gap between the heir's confidence with toxins and his total inexperience with romance, keeping the search for a bride connected to his attempt to protect someone he loves.
