In early September, the production team of the TV anime "MARRIAGETOXIN" released the key visual for the second season. At the same time, a clip was published that officially introduces the new motif as a "Main Visual Reveal PV" and also looks back at the first season.
The image focuses entirely on the series' mismatched duo: Hikaru Gero, heir to a family of hitmen and a so-called poison master, holds a syringe in his hand – the working tool of his trade. By his side stands the highly skilled marriage swindler Mei Kinosaki with a bouquet of flowers. In the background, the large bridge from the first episode of the first season is visible, where Gero once saved Kinosaki's life. Small symbols in the image also hint at characters who may play a role in the new episodes. The retrospective clip condenses Gero's journey through the bride search of the first season as well as the duels with the dangerous "Masters" he had to hold his own against.
The story remains as quirky as ever: To save his sister from being forced to bear an heir for the clan, the reclusive professional killer decides to get married – and asks for help from the very woman who was actually his assassination target. The main roles are once again voiced by Haruki Ishiya as Gero and Shion Wakayama as Kinosaki; the ensemble also includes Anna Nagase, Mariya Ise, Asaki Yuikawa, and Soma Saito.
The second season has been officially confirmed since the end of June and is scheduled to start in January 2027 on nationwide Japanese television; as before, it is planned for Tuesdays at 11:00 PM (JST) on Kansai TV and Fuji TV. Director Motonobu Hori, series writer Kimiko Ueno, character designer Kohei Tokuoka, and studio BONES FILM are returning. Hori said production is progressing as planned: A "charming new marriage candidate" awaits Gero, and the relationship between Gero and Kinosaki will also deepen further in the new episodes. At the same time, the director expressed surprise at the warm reception of the series among international audiences, such as during the team's appearance at Anime Expo 2026.
The source material is by Joumyaku, illustrated by Mizuki Yoda. The manga has been serialized since April 2022 in the "Shonen Jump+" app from publisher Shueisha; worldwide circulation now exceeds one million copies, with volume 18 released in early July. In the West, the series is available via Viz Media and on the Manga Plus platform, among others. The first season aired from April 7, 2026, over 13 episodes and told story arcs involving the Water, Sound, and Beast Masters; internationally, Crunchyroll streamed the episodes in simulcast. The opening song "Kill or Kiss" was contributed by Yurina Hirate, and the ending song "Shake Na Baby" was performed by AKASAKI. For the continuation, the series' motto remains: "Conquer love with poison."
