MARRIAGETOXIN

Romance · Comedy · Fantasy · Action

A poison specialist from an assassin family hires a marriage swindler as his dating coach, pairing lethal professional skill with complete romantic inexperience.

Synopsis
The Anime Lad

Hikaru Gero belongs to a powerful family of poison specialists and understands assassination far better than romance. Family succession pressure convinces him that finding a spouse has become urgent. Mei Kinosaki, a skilled marriage swindler, agrees to coach him. His professional résumé proves minimally relevant.

Super Eyepatch Fox

Poison specialist Hikaru lives inside a dangerous family trade and has no romantic experience. When succession pressure demands a marriage solution, he turns to Mei, a marriage swindler with expert social instincts. She makes his search for a partner into practical instruction.

Gigguku

Hikaru can handle poison with absolute control, then faces a problem his training never covered: finding a bride. Mei brings the social expertise of a marriage swindler. That contrast gives the marketed premise a sharp comic engine before either can claim ordinary romantic competence.

Father's Basement

The family's succession demand gives the comedy an uncomfortable foundation, and Hikaru's sudden need for marriage is deliberately extreme. Mei makes the setup workable. Her expertise concerns attraction and deception, while his belongs to poison, creating two professional skill sets with almost no overlap.

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.

What defines it

A dark action romantic comedy. Stylish and offbeat.
