__Specialist Type:__ Poison User

Hikaru Gero is part of the Gero Family, one of the top five families of specialists. He is the current heir to the Poison clan. A poison-using hitman from the clan of assassins. In order to keep his sister from being forced into having a child to continue the lineage of the clan, Gero decides to try and get married and have a child of his own.



For centuries, the deadly arts have been perfected by those known as the Masters.
Among them, the Poison Masters of the Five Great Families hold the most fearsome power and influence. 
Hikaru Gero, heir to the Poison Masters’ Gero Family, has lived his entire life in the underworld, far removed from love or marriage.
But when the Gero Family head decrees that Hikaru’s sister must bear an heir to preserve the bloodline—by force if necessary—Hikaru resolves to protect her at all costs.
It is then that Hikaru encounters Mei Kinosaki, a brilliant marriage swindler who becomes the target of his latest job.
Realizing that the only way of solving the family succession problem and protecting his sister is through marriage, Hikaru impulsively asks Mei for help in finding a bride.

A hitman and a marriage swindler set out on the world’s most grueling battle for marriage! Gero is a young man from a clan of hitmen, which has been in existence for hundreds of years. As someone who’s never gone to school and lived his life dealing in the dark side of the business, he considers himself to have “no prospects with women” and marriage as “something not for him.” However, one day, in fear that their lineage would dissolve, his clan warns Gero that if he doesn’t marry and produce an heir, they would have no choice but to…force his little sister into doing “that.” Driven to his wits’ end, Gero asks the target of his work, a marriage swindler, to…
