Marriage Toxin just fired the first shot of its comeback — and fans of Japan’s most chaotic assassin rom-com are already losing it. On Tuesday, the staff of the TV anime dropped the first promotional video and a brand-new key visual for Season 2, confirming that the poison-flavored love story will return in 2027. If you thought Hikaru Gero’s hunt for a bride couldn’t get any more dangerous, think again: the trailer teases bigger missions, deadlier rivals, and a romance that might finally cross the line.
The Trailer That Broke the Waiting Room
The new promo doesn’t waste a second. It opens exactly where Season 1 left fans hanging — Hikaru Gero, the heir of the Gero Family of Poison Masters, still desperately searching for the perfect wife with the help of Mei Kinosaki, a marriage swindler with a smile sharper than any blade. The key visual, meanwhile, puts the duo front and center with a backdrop of flowers and poison — a fitting metaphor for a show where love and death share the same cup.
What makes this announcement extra spicy? The second season is coming with its entire creative team intact. Motonobu Hori, best known for directing Carole & Tuesday, is back in the director’s chair at Bones Film, with production supervision from BONES itself. That’s not just a flex — it means the same action choreography, the same visual polish, and the same wild tonal shifts that made Season 1 a sleeper hit.
Meet the Deadliest Duo in Shonen Jump+
If you’re new here, here’s the pitch: for centuries, the Poison Masters of the Five Great Families have perfected the art of killing. Hikaru Gero, heir to one of those families, has lived his whole life in the underworld — until the family head drops a bombshell: his sister must bear an heir to preserve the bloodline, by force if necessary. To protect her, Hikaru decides the only way out is to find a bride himself. That’s when he runs into Mei Kinosaki, a brilliant marriage swindler who becomes the target of his latest job — and ends up as his partner instead.
“That’s the first time anyone’s ever proposed like that,” Mei quips in the show’s signature style. And so begins the world’s toughest mission for love: an elite assassin and a con artist trying to engineer the ultimate marriage. To win love, you’ve got to play with poison.
A Dream Team Behind the Poison
Season 2 isn’t just repeating what worked — it’s doubling down. The returning staff reads like a who’s who of modern anime talent:
- Director: Motonobu Hori (Carole & Tuesday) at Bones Film, supervised by BONES
- Series composition & scripts: Kimiko Ueno (Astro Note)
- Music: Taisei Iwasaki (BELLE) and Yuma Yamaguchi (Metallic Rouge)
- Chief animation director & character designer: Kōhei Tokuoka (The Fragrant Flower Blooms With Dignity)
That’s the same core squad that delivered Season 1’s knockout debut on April 7, when the anime premiered on Kansai TV and Fuji TV’s brand-new Tuesday night block “Ka-Anival!!” — with Crunchyroll streaming it for international fans as it aired.
A Franchise on Fire
Behind the anime is one of Shonen Jump+’s most addictive reads. Marriage Toxin started in April 2022 with story by Jōmyaku and art by Mizuki Yoda, and it has been climbing ever since — Shueisha shipped the manga’s 18th compiled volume on July 3, with Viz Media handling the English release and the series available worldwide on the MANGA Plus app.
The music side of Season 1 was just as memorable: actress and singer Yurina Hirate delivered the explosive opening theme “Kill or Kiss,” while singer-songwriter AKASAKI closed every episode with the smooth “Shake Na Baby.” If Season 2 follows the same formula, we’re in for another stacked soundtrack.
Why Everyone’s Watching in 2027
Sequels are the theme of the moment in anime — 2026 has already given us massive returns like Chainsaw Man Season 2 and Black Clover’s comeback, plus record-breaking surprises like the Chiikawa film that just outsold every major anime movie at Japan’s box office. Marriage Toxin walking into 2027 with a full returning staff is a signal that Shueisha and Bones Film believe in this one long-term — and honestly, after that trailer, so do we.
The big question now: how far will Season 2 push the romance? The manga has plenty of material — new Poison Master families, deadlier contracts, and a slow-burn tension between Hikaru and Mei that fans have been screaming about for chapters. One thing’s certain: the hunt for the ultimate wife just got a lot more dangerous.
