K Manga Adds Daisaku Tsuru's "Protocol Ryugu" Manga Series to Its Platform
K Manga, Kodansha's popular digital manga platform, has added the new series "Protocol Ryugu" by artist Daisaku Tsuru to its Japanese publication list. The series' Japanese serialization began on Thursday, June 17, 2026, while it had previously debuted in English.
This move is seen as part of K Manga's strategy to embrace both Western and Japanese readership simultaneously. Daisaku Tsuru, known especially for series like "Hikaru no Go" (with Yumi Hotta) and "CØDE:BREAKER", is considered one of the masters of visual storytelling in manga. The new series "Protocol Ryugu" takes its name from Japan's legendary undersea palace Ryugu and blends science fiction with mythology. Early chapters follow the adventures of a young hero tracking a mysterious protocol in the ocean depths.
The series' original English release aimed to build a global readership; the Japanese serialization now aims to capture the same interest in its home country. The K Manga platform has recently been offering many new series simultaneously in both Japanese and English, shaping the digital manga reading experience to transcend borders. For "Protocol Ryugu", fans note that the first few chapters are available free online, with new chapters to be released weekly.
This new series by Daisaku Tsuru was eagerly awaited, especially by fans of "Hikaru no Go" and "CØDE:BREAKER". Tsuru's dynamic drawing style and complex storylines may lead to "Protocol Ryugu" quickly gaining popularity. With this addition to K Manga, the series is expected to appear on other digital platforms as well. This development, which could herald manga adaptations and animation projects, is an exciting step for fans celebrating Tsuru's return.
In the coming weeks, more details are expected to be announced regarding the regular flow of "Protocol Ryugu" chapters and possible physical volume releases. K Manga users can already read the first chapters and step into Tsuru's mystical science-fiction world.
