Marriage Toxin, Vol. 15: Volume 15

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 taking on his toughest 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 will do whatever it takes to get Gero hitched—even if they have to take on the entire criminal underworld in the process!

Young entrepreneur Shiori Ureshino’s family business is in trouble! With the schemes of a rival competitor driving her company’s profits down the tubes, Ureshino turns to Gero for help. Will the Poison Master be able to help her turn the company around? Plus, while Gero is busy working with Ureshino, he also finds out that someone’s been manipulating Kinosaki behind his back! The question now is, what nefarious purpose could they possibly have for targeting his marriage advisor?!
