MARRIAGETOXIN unveiled a new key visual and two cast additions as the anime enters its Beast Tamer Arc beginning with Episode 8.
Studio BONES Film's MARRIAGETOXIN anime has entered its Beast Tamer Arc with the airing of Episode 8 on May 26, 2026. Alongside the new arc, the production unveiled a fresh key visual drawn by character designer Kohei Tokuoka and confirmed two new voice cast members joining the series.
The Beast Tamer Arc introduces two pivotal characters to the story. Kazuyuki Okitsu, known for his extensive voice acting career, steps into the role of Toshiro Dogo, while Ayaka Suwa takes on the role of Byakko. Both characters feature prominently in the newly released key visual, signaling their importance to the arc's storyline. Their addition expands an already stacked ensemble that has carried the series through its first seven episodes.
The new key visual, supervised by chief animation director and character designer Kohei Tokuoka, places Toshiro Dogo and Byakko alongside the established cast. The visual sets a markedly different tone from the earlier promotional art, reflecting the shift in narrative focus as the Beast Tamer Arc takes center stage. Tokuoka has been instrumental in defining the show's visual identity since its premiere, and the latest artwork maintains the series' sharp, detailed character designs.
MARRIAGETOXIN premiered on April 3, 2026, with Motonobu Hori directing at Studio BONES Film. Kimiko Ueno handles series composition and scripts. The anime follows a cast led by Shion Wakayama as Mei Kinosaki, Haruki Ishiya as Hikaru Gero, Anna Nagase as Kyoko Himekawa, and Mariya Ise as Shizuku Ushio. Additional cast members include Asaki Yuikawa as Shiori Ureshino, Soma Saito as Genya Naruko, Hinano Shirahama as Kimie Arashiyama, and Simba Tsuchiya as Piichi Nakagawa. The series has built a steady following through its opening arc, blending dark comedy with action as it adapts the manga of the same name.
MARRIAGETOXIN streams on Crunchyroll, making it accessible to viewers worldwide including those in India through the platform's global simulcast. New episodes air weekly as the Beast Tamer Arc continues to unfold. With seven episodes already available, new viewers can catch up before diving into the latest narrative turn.
The addition of Okitsu and Suwa to the cast alongside the arc-shifting key visual suggests MARRIAGETOXIN is ramping up for a significant stretch in its first season. Episode 8 is now streaming, with the Beast Tamer Arc set to develop in the weeks ahead.
