Plot summary
Hikaru Gero is a young man from the Poison Clan of professional assassins, which has been in existence for hundreds of years. Because he deals in the dark side of society and has never lived a "normal life", he considers himself to have no prospects with women and has no interest in marriage. However, one day, the Poison Clan states that if Gero does not marry and produce an heir to carry on their lineage, they will force his sister into bearing a child against her wishes. Wanting to save his younger sister from such a fate, Gero asks one of his assassination targets to marry him. When the cross-dressing marriage swindler Mei Kinosaki declines, Gero instead has Kinosaki train him to date and how to appeal to women with the goal of finding someone he truly wants to marry.

Reception
Marriagetoxin was nominated for the Next Manga Award in the Best Web Manga category in June 2022, and ranked eighth out of 50 nominees. It also ranked fifth in the Nationwide Publishers Recommended Comics of 2023. The series was recommended by Koyoharu Gotouge, Gege Akutami and Mogumo, the character designer for the anime series Mobile Suit Gundam: The Witch from Mercury.
The first volume received positive reviews for its art and action sequences. Hikaru Gero has been singled out as a "[v]ery relatable lead" with praise aimed at his design and his relationship with the "bubbly and energetic" Mei Kinosaki. Some criticism was aimed at Kinosaki's supporting role in the story rather than being a "fully realized character."
