Shueisha has expanded the catalog of its global digital platform, Manga Million, with the addition of Together with Serial-san (Serial-san to Issho) by Hiromasa Okujima. The series, which debuted in the publisher's Grand Jump Mucha magazine on February 25, is described as a "twisted, chaotic comedy" centered on a college student who invites a notorious serial killer to live in his home under the guise of an identity swap. Okujima, a creator with a history of diverse genre work, is also recognized for the series Baban Baban Ban Vampire, which was adapted into a Netflix anime in January 2025 and a live-action film in July 2025.
