MARRIAGETOXIN Lead Haruki Ishiya Discusses Gero’s Marriage Dreams and the Series' Chaotic World
MARRIAGETOXIN, one of the most popular series on the Shonen Jump+ platform, has remained a hot topic since its rapid entry into the anime world on April 7, 2026. Famous voice actor Haruki Ishiya, who voices the series' main character Hikaru Gero, evaluated the character's greatest motivation and the story's chaotic structure in an interview at Sakura-Con. According to Ishiya, the greatest appeal of Gero, one of the world's most dangerous assassins, is the fact that he simply dreams of a 'normal marriage'.
Haruki Ishiya stated that the first episode of the series perfectly reflects the overall tone of the story. 'Gero dreaming of a normal marriage is probably one of the most attractive points of the story,' the artist said, emphasizing that the madness coming from all directions in the first episode fully summarizes the MARRIAGETOXIN spirit. Ishiya also expressed that he usually voices characters younger than himself, but portraying a taller and more mature character like Gero is an important turning point in his career after 14 years of experience.
The anime, produced by Bones Film, a new department of Studio Bones, is brought to life under the leadership of director Motonobu Hori. The story follows Gero, the heir to a clan of poison users, who is forced to find a wife to save his sister from a forced marriage. Our hero, who has zero social skills, forms an unexpected partnership along the way with a marriage scammer named Mei Kinosaki. While the opening theme of the series is 'Kill or Kiss' by Yurina Hirate, AKASAKI's song 'Shake Na Baby' accompanies fans during the ending.
The original manga, written by Joumyaku and illustrated by Mizuki Yoda, has gathered a large fan base with its dynamic illustrations and absurd humor since its debut in 2022. The success of the anime adaptation lies in its ability to bring that unique energy of the manga to the screen. As Ishiya noted, the contrast between Gero's perfection as an assassin and his amateurism regarding romance makes the series indispensable for fans of both action and romantic comedy. Fans are eagerly waiting to see how Gero will develop on this strange marriage journey.
