Shogakukan’s Big Comic Superior magazine has released the final chapter of the first season of the Mujina Into the Deep manga by Asano Inio. The final chapter was released in the magazine’s ninth issue of 2026 on April 10th, 2026, and it also confirmed that the manga will return with season 2 in 2027.
Manga author Asano (Dead Dead Demon’s Dededede Destruction) explained on his Twitter account that the long hiatus was due to reaching the limit of his physical stamina and running out of material.

Asano started the manga in March 2023 in Shogakukan’s Big Comic Superior magazine, and Shogakukan published the manga’s first tankoubon volume in September 2023 and the fifth in November 2025. The manga’s sixth volume is scheduled for release on May 29th, 2026.
Viz Media publishes the manga in English under the same name, and it will release the fourth volume on May 19th, 2026. Viz Media describes the manga story below:
“Terumi Morgan bitterly accepts that he shouldn’t expect a lot from life. He just wants to meet his deadlines at work and watch his porn in peace. But then an unexpected sick day sends him on a collision course with two people who will change his world forever—a runaway kid and a thirtysomething mujina assassin. Suddenly life is expecting a lot from him.”
