Preliminary cut of TV anime “Marriage Toxin” episode 1
``Marriage Toxin'' is a comical battle action movie that depicts the unique buddies of a hitman and a marriage fraudster taking on the difficult mission of ``match hunting.'' Hikaru Gero, the next head of the Gero family, a family of assassins and poison users, has been working in the underground business and has lived without having anything to do with women. Marriage was irrelevant to him, but his grandmother, who is the current head of the family, informs him that in order to keep the blood of poison users from dying out, he will have his younger sister Akari give birth to an heir. The first episode, "The Poison User's Marriage Hunting," for which a preliminary cut was released, is about Hikaru, who decides to get married to protect his sister, and proposes to Mei Kinosaki, a marriage fraudster who he met as a target for murder.
