Marriage Toxin Anime Sets April Premiere: A Deadly Date with Comedy

Mark your calendars and maybe write a will, because the highly anticipated anime adaptation of Marriage Toxin finally has a launch date. The official website dropped the news this Saturday: the series will begin its broadcast run on April 7. It's found its home in the new Tuesday night programming block "Ka-Anival!!" on Kansai TV and Fuji TV. Consider this your formal invitation to a weekly appointment with chaos.

A Creative Team with Serious Pedigree

Assembling an anime is like cooking a complex dish; you need the right ingredients and a skilled chef. For Marriage Toxin, the kitchen is in capable hands. Directing the series is Motonobu Hori, whose previous work includes the musical vibes of Carole & Tuesday. He's steering the ship at BONES Film, with the main BONES studio providing production supervision—a powerhouse combo known for fluid action and striking visuals.

Handling the script and series composition is Kimiko Ueno (Astro Note), who will be tasked with translating the manga's unique blend of high-stakes assassination and marital farce. The soundtrack, crucial for setting the tone of this bizarre world, is in the hands of composers Taisei Iwasaki (BELLE) and Yuma Yamaguchi (Metallic Rouge). And ensuring the characters look sharp enough to kill (or to fall in love with) is chief animation director and character designer Kōhei Tokuoka (The Fragrant Flower Blooms With Dignity).

The Source Material: A Lethal Love Story

For those not yet in the know, Marriage Toxin isn't your typical romance. The manga, created by writer Jōmyaku and artist Mizuki Yoda, began its serialization on Shueisha's Shonen Jump+ app back in April 2022. It's a story that asks the age-old question: what if your arranged marriage partner was a world-class assassin, and your family's tradition demanded you kill them? Hilarity and heart-pounding action ensue.

The series has been a consistent hit, with Shueisha publishing its 16th compiled volume just this past January. For international fans, the manga is readily available in English through Viz Media and on Shueisha's MANGA Plus service, so you have no excuse not to catch up before the anime hits.

What to Expect Come April

Anime adaptations of popular Jump+ titles have a strong track record, and with BONES at the helm, the expectations are sky-high. The premise alone—mixing the cold calculus of contract killing with the warm, awkward fumbling of newlywed life—is a recipe for something special. It's a volatile cocktail, a marriage of genres that could either explode spectacularly or become your new favorite show. We're betting on the latter.

The reveal of the new key visual on the anime's website gives us a taste of the dynamic between the leads, promising the sleek action and expressive character work BONES is famous for. So, set a reminder for Tuesday, April 7. It's time to see if love really is a battlefield, or in this case, a carefully planned assassination attempt gone charmingly wrong.
