Marriage Toxin Season 2 Confirmed for 2027 With New Trailer and Visual

Good news if you got hooked on Marriage Toxin. The anime is officially coming back for a second season in 2027. Along with that announcement, a new promotional video and a fresh key visual were revealed. Nice and clean. No vueltas.

Season 2 is already on the way

The first season premiered on April 7, and now the follow-up has its window set for 2027. That means the series is wasting no time keeping the momentum alive. When an anime locks in another season this early, that usually tells you one thing: there is confidence in the project.

And yes, the main creative team is returning. That is a big deal. In anime, a stable staff can help keep the tone, visual identity, and pacing from falling apart. Nobody wants a sequel that feels like it got cooked in a different kitchen, va.

The returning staff behind the anime

The second season brings back key names from the first run:

• Motonobu Hori directs at Bones Film, with production supervision by BONES.
• Kimiko Ueno handles series composition and scripts.
• Taisei Iwasaki and Yuma Yamaguchi compose the music.
• Kōhei Tokuoka returns as chief animation director and character designer.

That lineup matters. BONES has a strong record, and keeping the same script and music team helps maintain the feel that viewers already know. It is like ordering the same pupusa from the same puesto: you expect the flavor not to betray you.

What Marriage Toxin is about

If you are just hearing about it, the setup is wild in the best way. The story follows Hikaru Gero, heir to a family of poison users feared in the underworld. He has zero normal experience with romance, but suddenly he gets pushed into a problem tied to family succession and marriage.

That is where Mei Kinosaki enters. She is a sharp marriage swindler, and somehow she becomes the person helping Hikaru find a bride. So yes, the central duo is basically an assassin and a con artist trying to solve a marriage crisis. That premise alone hits hard.

The mix works because it throws together danger, comedy, and romance with constant tension. Love is already complicated. Now add poison, family pressure, and criminal-level social skills. Qué relajo.

First season details

The anime began airing on Tuesdays on Kansai TV and Fuji TV's Ka-Anival!! programming block. It was also streamed by Crunchyroll as it aired.

The opening theme for season one was "Kill or Kiss" by Yurina Hirate. The ending theme was "Shake Na Baby" by AKASAKI. Those songs helped shape the show's identity, especially with a title like Marriage Toxin, where the whole vibe sits between attraction and danger.

The manga keeps growing

The original manga by Jōmyaku and Mizuki Yoda launched on Shonen Jump+ in April 2022. Since then, it has kept building a solid run. The series already reached 18 compiled volumes as of July 3.

That number says a lot. A manga crossing into the high teens in volume count usually means there is enough material to support more anime, and enough audience interest to keep the machine moving. 18 volumes in a little over 4 years is a strong pace. No está jugando.

For English readers, the manga is available through Viz Media and also on MANGA Plus.

Why this sequel matters

Marriage Toxin is not your usual romance setup. It leans into absurdity, danger, and awkward emotional growth. That gives it a sharper hook than many standard love stories. The return of the staff also suggests the second season will aim for consistency instead of reinventing everything just because it can.

Short version: new trailer, new visual, same core staff, and a 2027 release window. If the first season pulled you in, this is the kind of update you wanted. If not, this may be a good time to catch up before season two lands and everybody starts talking like they discovered poison-powered matchmaking yesterday.
