Studio DEEN is adapting the light novel by Ryosen Takami, and the new PV also reveals the opening and ending songs.
The TV anime Multi-Mind Mayhem (Isekai Tensei Soudouki) premieres on Japanese television on January 6, 2027. Publisher AlphaPolis has confirmed the date and released a second key visual along with the second official trailer. The series is being produced by Studio DEEN, which is also behind the January premiere of Dengeki Daisy, and adapts Ryosen Takami's fantasy light novel series.
Three Souls in One Body
At the center of the story is Balud, son of a noble family from the Kingdom of Mauricia. Within his body also live the souls of former samurai Sakon Oka and modern-day student Masaharu Oka. Their abilities help him manage his territory, engage in trade, and fight. Inventions drawing on Masaharu's knowledge change Balud's standing in the world.
The new trailer includes excerpts from both theme songs: "Isekai" by Maverick Mom is the opening, and "Brand new day" by Tokino Sora is the ending.
