Manga launched on June 25

This year's 50th issue of Shueisha 's Weekly Shonen Jump magazine published the final chapter on Monday of Keiji Amatsuka's Sogo Jikan Jigyo Gaisha Daihyo Torishimariyaku Shacho Senzoku Hisho Tanaka Seiji ( Seiji Tanaka: Secretary to the Managing President, General Time Industries ) manga. The manga's second and third volumes will both ship on January 4.

Amatsuka launched the manga in Shonen Jump on June 25, and Shueisha published the manga's first compiled volume on October 4.

Viz Media previewed the first three chapters of the manga in English as part of its "Jump Start" initiative, and it describes the story:

Nagato Tokioka is the ultimate slacker with zero future aspirations. But when Seiji Tanaka, a battle secretary from the future, appears claiming that assassins from the future are planning to kill him, Tokioka's future is about to change forever.

Amatsuka previously published the NECRO manga in Shonen Jump NEXT in 2015, and published a one-shot with the same "Tanaka Seiji" title in Weekly Shonen Jump in 2016.
