Gero may be a master assassin, but he’s 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 couldn’t be more clueless when it comes to dating, but thankfully, marriage swindler Mei Kinosaki knows everything there is to know about love. Together, this unlikely pair is going to do whatever it takes to get Gero hitched—even if they have to take on the entire criminal underworld in the process!

It’s Poison Master versus Poison Master as Gero is forced to face off against his own cousin, Teruaki! After learning about Gero’s frivolous marriage plans, Teruaki targets Kinosaki in order to help Gero regain his focus as heir to the Poison Clan. But Teruaki’s tolerance to poison may be even higher than Gero’s own. Can he stop Teruaki and save Kinosaki before it’s too late?!
