Sgt. Frog Manga Goes Free for All 35 Volumes Before New Anime
KADOKAWA has announced a limited-time free reading fair for the long-running manga Sgt. Frog (Keroro Gunso), offering all 35 collected volumes at no cost for just two days. The promotion runs October 1 and October 2, 2026, and is designed to let readers revisit the series’ lengthy history ahead of a brand-new TV anime adaptation. That new anime is scheduled to begin broadcasting on October 3, 2026, immediately after the free period ends. The campaign carries the title “Right Before the Anime! Sgt. Frog – Read It All Edition.”
The fair covers volumes 1 through 35 of the Sgt. Frog manga and is being held across various digital e-book stores. KADOKAWA notes that the exact end time, pricing, and eligible titles may differ between retailers, so readers are advised to check each store’s own details. The publisher frames the event as an opportunity for three groups: those who were once absorbed in the series, those currently following the latest chapters, and those about to encounter it for the first time. All 35 volumes are available free during the window.
The free reading period is timed to lead directly into the new Sgt. Frog TV anime, which premieres October 3, 2026. According to KADOKAWA, the campaign allows audiences to look back at the series’ past “invasion” storylines in one sweep before the broadcast begins. The series has been loved for many years and remains a popular, ongoing serialization, making this a chance to catch up on its full run so far.
KADOKAWA, based in Chiyoda, Tokyo and led by CEO Tsuyoshi Natsuno, is the company behind the campaign. The promotion lasts only until 23:59 on October 2, 2026, giving readers a narrow two-day window to move through all 35 volumes. The publisher is encouraging both returning and new readers to take part before the anime airs. For anyone curious about the franchise, this brief free period is a convenient entry point.
