Marriage Toxin, Vol. 5

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!

Gero swore to protect Hamster Master Arashiyama, but she’s been kidnapped by the Beast Master! Now, Gero must team up with none other than Piichi the Hit Man Hunter to help rescue her. But the Beast Master is two steps ahead--have they been playing into his hands this whole time? And what does the unexpected return of Water Master Ushio mean for Gero?!

Includes the bonus one-shot ＂Hyper Hard Special Mission,＂ an exciting prequel story featuring Piichi and his girlfriend, Marin!
