Gero may be a master assassin, but he's absolutely clueless when it comes to romance, so marriage swindler Mei Kinosaki steps in to help him find true love. Together, this unlikely duo takes on the entire criminal underworld in their quest to get Gero hitched. When Gero's cousin Teruaki targets Kinosaki to refocus Gero on his duties as heir to the Poison Clan, a deadly Poison Master versus Poison Master showdown erupts. Teruaki's tolerance to poison might even surpass Gero's own, forcing him into a desperate fight to save Kinosaki before it's too late.

This action-packed volume continues the hit series from writer Joumyaku and artist Mizuki Yoda, blending high-stakes combat with hilarious romantic misadventures. Perfect for fans of unconventional love stories and over-the-top battles.
