The official Twitter account for Kodansha’s Comic Days manga app revealed on Tuesday that the Kaiji spinoff manga Mr. Tonegawa: Middle Management Blues (Chūkan Kanriroku Tonegawa) will end in three chapters.
The manga focuses on the “agonizing daily life of Teiai Group executive Yukio Tonegawa, who gets into conflicts with Hyōdō and the black suits.”
The series then switched to Comic Days in March 2018.
The series ranked at #1 on the top 20 list of manga for male readers in the 2017 edition of Takarajimasha’s Kono Manga ga Sugoi!
