The June issue of Kodansha's Bessatsu Shonen Magazine will announce on Saturday that Tahi Saihate and Mitsuru Hattori will launch a new novel series titled Bokura wa Satsui Biyori (We're In the Mood for Murder) in the magazine's next issue, which Kodansha will publish on June 9. The novel will have a color opening page.

The magazine teases:

17-years old. Right beside me is the season where death is.

Saihate will write the novel's story, while Hattori will draw the art.

Saihate serialized her Mahō Shōjo WEB novel in Kodansha's Bessatsu Shonen Magazine from 2012 to 2013. She also serialized some of her poems, such as "Sora ga Bunretsu Suru," in the same magazine, and published her anthology of poems in her book Shindeshimau Kei no Bokura ni .

Hattori launched his Sankarea manga in Kodansha's Bessatsu Shonen Magazine in 2009, and ended it in September last year. Kodansha Comics published the manga's 11th and final volume in North America in March. The manga inspired a television anime in 2012, and Funimation released the anime in North America in 2013, but that release was recalled. Funimation then released an uncut version on home video in March.

Additionally, the July issue of Bessatsu Shonen Magazine will also start Yōsuke Kokuzawa's (Chōjin Gakuen) Shonobi no BAN (pictured at left) "ninja battle royale" manga. Hiroyuki's Aho Girl manga will also switch from Weekly Shonen Magazine to Bessatsu Shonen Magazine with the July issue.

Hiroyuki's Aho Girl (Stupid Girl) manga began in Weekly Shōnen Magazine in 2012. The story revolves around high school girl Yoshiko, who is so ridiculously stupid everyday that even her childhood friend Takkun wants to give her a big punch.

Update: The series is a novel, not manga.
