Marriage Toxin, Vol. 7 Joumyaku (2025)

Gero may be a master assassin, but he is not exactly killing it in the romance department. Can marriage swindler Kinosaki help him find true love? Poison Master Hikaru Gero is about to take on his most challenging assignment yet: getting married. Gero is completely clueless when it comes to dating, but fortunately, marriage swindler Mei Kinosaki knows everything there is to know about love. Together, this unlikely pair will do whatever it takes to get Gero hitched, even if they have to take on the entire criminal underworld. It is Poison Master versus Poison Master when Gero is forced to face his cousin Teruaki. After learning about Geros frivolous marriage plans, Teruaki targets Kinosaki to help Gero regain his focus as heir to the Poison Clan, but Teruakis tolerance to poison may be even higher than Geros own. Can Gero stop Teruaki and save Kinosaki before it is too late?
