Marriage Toxin

For centuries, the art of assassination has been dominated by the Gero family, unrivaled experts in the use of poisons. Hikaru Gero, the heir to this terrifying lineage, has lived in the shadows, confined to the secret world of contract killers, without ever considering a romantic relationship or marriage. However, when Hikaru’s father, the head of the family, forces his younger sister to take on the responsibility of continuing the Gero lineage through motherhood, Hikaru rebels against this decision.

It is under these circumstances that he meets Mei Kinosaki, a master of deception who specializes in marriage scams… and who also happens to be his current target. Instead of carrying out his mission, Hikaru makes a surprising decision: he asks Mei to help him find a woman to marry. From this unlikely partnership emerges a dynamic duo: an elite assassin and a feared con artist, embarking together on the most dangerous mission of all… planning the perfect wedding!
