Master assassin Gero is a pro at taking down targets, but when it comes to romance, he's completely out of his league. Enter marriage swindler Kinosaki, who's about to teach this clueless killer everything he needs to know about love. Together, this unlikely duo dives headfirst into the criminal underworld, determined to get Gero hitched no matter what chaos comes their way.

Now fully recovered thanks to Sound Master Naruko, Gero is racing to rescue Himi from a wedding that's more nightmare than fairy tale. Ghost Master Sakazuki stands in his path with a bag full of devious tricks, and even if Gero pulls off the rescue, will he finally clue in to Himi's true feelings for him?
