What is Marriagetoxin about?

Between all the wild action, Marriagetoxin is about a young man trying to find love while not being particularly good at romance. Hikaru Gero is the heir to a clan of Poison Masters and is considered one of the best assassins in the world. While he’s never had time for love, he throws himself into his quest to find a bride when his sister is ordered to have a child to continue the bloodline. Hikaru is aided by Mei Kinosaki, a notorious marriage swindler who has tricked multiple men into marrying them. The twist: Mei is a man crossdressing as a woman to con rich men out of their money. Together, the pair need to navigate the violent criminal underworld while finding a woman Hikaru can talk to without breaking into a nervous sweat.

Will there be a Marriagetoxin season 2?

We certainly hope so! However, new seasons aren’t usually announced until the previous season is finished. As such, we don’t expect to hear anything about Marriagetoxin Season 2 until at least the end of June 2026.

How many episodes will be in Marriagetoxin Season 1?

There will be 13 episodes in Marriagetoxin Season 1, meaning that the final episode of the season will air on June 30, 2026. After that, we may be in for a long wait before more episodes come out, as a second season hasn't been announced yet.

Is the Marriagetoxin manga ongoing?

The first chapter of Marriagetoxin debuted in April 2022. Since then, 17 volumes have been published by Shueisha and localized in English by Viz Media. The manga, which is written by Joumyaku and illustrated by Mizuki Yoda, is still going strong with no ending in sight, but there is clearly enough material for a second season of the anime if the first one does well.
