He's an assassin who can't find a wife—so he'll have to fight his way into a future!
Koga Gero is a highly skilled poison-user from a long line of assassins, but he's not interested in following the family tradition—or dying out with it. When he learns that his bloodline is in danger of disappearing, Gero makes an unusual deal with a mysterious matchmaker: he'll work to find a wife while taking on increasingly dangerous missions. Joined by his transgender sister and a clever marriage broker, Gero battles rival assassins and deadly poison users in a wildly inventive action series that mixes high-stakes combat with comedy and heart.
