The popular anime series returns next week with an episode where Ureshino makes a dangerous request to Gero.
The action-comedy anime Marriage Toxin is gearing up for its next installment. Episode 6, titled “Together With Me,” arrives on May 12, 2026. The show follows Hikaru Gero, an elite assassin who knows nothing about romance, and Mei Kinosaki, a skilled marriage swindler he recruits to help him find a wife.
Episode 5 ended with a tense cliffhanger. The university training camp turned into a deadly battlefield when the Sound User assassin Genya Naruko attacked. Naruko used sonic-based attacks to create chaos, separating Gero from the others.

About the Series
Marriage Toxin tells the story of Hikaru Gero, the heir to a family of Poison Masters. He has spent his whole life in the underworld, killing targets with his deadly skills. But he has zero experience with women or dating. When his grandmother threatens to force his sister to produce an heir, Gero decides he must get married to protect her.
His solution comes when he meets his assassination target—Mei Kinosaki, a cross-dressing marriage swindler who can charm anyone in 30 seconds. Instead of killing Kinosaki, Gero asks for help. The series follows this strange pair as they navigate dating advice, assassin fights, and family drama.
“That’s a first… for a ‘proposal,’ anyway,” Kinosaki responds when Gero first asks for help.
The anime combines action sequences with dark comedy and awkward romantic moments. Each episode balances high-stakes fights with Gero’s clueless attempts at being charming.

What Happened Before Episode 5
Episode 4 introduced Ureshino as Gero’s new bodyguard assignment. Gero went undercover as a university student to protect her from assassins. The episode showed Gero experiencing normal college life for the first time—attending classes, going to social gatherings, and trying to fit in. But the fun ended when Naruko attacked during a training camp.
Episode 5, titled “Lord Chladni,” focused entirely on the camp battle. Naruko set up traps throughout the area and played mind games with the students. The episode revealed that Ureshino was named the next company president, which triggered the assassination order. The question of who hired Naruko remained unanswered by the end.
