Episode 8: "The Hitman Hunter"
Taking Kinosaki’s expert advice to heart, Gero is back on the marriage grind. His next potential lead is Kimie Arashiyama, the eccentric "Hamster master." Despite being a specialized "Master" (a clan of hereditary assassins), Kimie is a total pacifist who’s useless in a fight. Terrified of a mysterious figure known as the "Hitman Hunter," she begs Gero to be her bodyguard. Gero finds himself swept up in her frantic energy and agrees to the job. Meanwhile, Kinosaki is actually optimistic about the pairing—could a spark fly between two fellow Masters?
Later, Gero and Kinosaki accompany Kimie to a gathering of the "Beast master" branch families. However, the meeting takes a deadly turn when Gero finally comes face-to-face with Momochi Nakagawa, the legendary Assassin Hunter. Despite being a "normal" human without hereditary powers, Nakagawa is a combat prodigy whose skills eclipse even the most elite professional killers. Just what is this man’s true objective...?
About "Marriagetoxin"
Synopsis
For hundreds of years, the "Users" have honed the ultimate arts of assassination. Among them, the "Poison Users" of the Five Great Families hold the most absolute power and authority. Hikaru Gero is the young heir to this lethal bloodline. Having spent his life in the shadows of the underworld, he has had zero experience with women—making "marriage" a concept from a different universe.
However, to ensure the Poison User lineage does not die out, the head of the Gero clan issues an ultimatum: Gero’s younger sister will be forced to produce an heir against her will.
Desperate to protect his sister and resolve the succession crisis, Gero encounters his latest target—Mei Kinosaki, a master marriage swindler. Realizing this is his only chance, Gero decides to get married himself and recruits Kinosaki as his coach right then and there.
"That's... the first time anyone has ever proposed to me like that."
With a professional con artist as his advisor, the elite assassin embarks on the most difficult mission of his life: marriage hunting. The curtains rise on the world’s most intense matchmaking battle action, featuring the ultimate assassin-swindler duo!
