The May issue of Kodansha's Bessatsu Shōnen Magazine announced on Thursday that the planned manga adaptation of Hyogo Onimushi and Tabinomichi's Return to Shironagasu Island game will launch in the magazine's next issue on May 9. The magazine lists Muratan as the new artist for the manga series. The first chapter will have a color opening page.

Frontier Works' booth at the Comic Market (Comiket) 103 event originally announced the manga in December 2023. The manga was slated to debut in Kadokawa's Monthly Young Ace magazine in 2024, with Kuroitsu Suruga as the artist, but the magazine announced the manga's cancelation in April 2024 due to the "poor efforts" of its editorial team resulting in scheduling problems for the manga.

Tabinomachi describes the game on Steam:

Tabinomichi released the game on Steam in March 2020 with Japanese audio and text in 11 languages, including English. The game is also available physically in Japan for Windows. The company room6 also released the game for Nintendo Switch in several languages including English in November 2022.

A novel adaptation of the game shipped in two complete volumes in September 2023. Hyogo Onimushi is credited with the story and Shiroi drew the illustrations.
