MARRIAGETOXIN Anime Adaptation Announced for 2026



Shueisha has recently announced an exciting development in the anime world; the popular manga series MARRIAGETOXIN, created by Joumyaku and illustrated by Mizuki Yoda, is set to receive a television adaptation that will air in 2026. Produced by BONES Film, the studio known for hits like My Hero Academia and Gachiakuta, this announcement marks a significant moment for fans of the series.

A Unique Premise



MARRIAGETOXIN delivers a unique blend of genres, showcasing a marriage-centered narrative steeped in action and adventure. The story follows Hikaru Gero, a proficient assassin and heir to the Poison Masters Clan, who struggles with the expectations of marriage due to his family's legacy. With a perfect combination of comedy, romance, and action, the anime aims to captivate audiences around the world.

Hikaru, voiced by Haruki Ishiya, epitomizes the skilled yet emotionally guarded assassin, while Mei Kinosaki, portrayed by Shion Wakayama, embodies the charming and smooth-talking marriage swindler. Their unexpected partnership, sparked by a series of events leading to an unusual proposal from Hikaru, sets the stage for a thrilling adventure filled with dynamics between love and deceit.

Visuals and Animation Team



The first teaser visual released gives a sneak peek into the anime's aesthetic, depicting Hikaru brandishing his iconic poison amidst a picturesque city skyline, paired with Mei holding a bouquet of flowers. The teaser trailer hints at their turbulent interactions and the stakes involved in their quest for love.

The creative team behind the anime includes director Motonobu Hori, known for his work on Carole & Tuesday, and Kohei Tokuoka, serving as chief animation director and character designer, bringing expertise from projects like SK8 the Infinity. Their collaboration promises a visually stunning adaptation that captures the essence of the original manga.

Characters with Depth



Hikaru Gero is not your typical assassin. With little experience in romance, he’s pulled into the world of marriage negotiations, determined to secure a future for his family's bloodline. Mei Kinosaki, on the other hand, is seasoned in the art of charm and persuasion. The juxtaposition of their personalities adds layers to the story, making it a delightful journey for audiences.

Both characters showcase an interesting dynamic: while Hikaru is wary and serious, Mei's light-hearted approach adds a comedic touch to their high-stakes situation. As they embark on this unconventional mission for love, viewers can expect both thrilling action sequences and heartfelt moments.
