Frog Manga Goes Free Across Ebook Stores Ahead of New Anime","summary":"Kadokawa is running an all-volumes-free fair for Mine Yoshizaki's manga Sgt. Frog on October 1 and 2, 2026, ending at 23:59 each day. Volumes 1 through 35 are readable at no cost on BOOK☆WALKER, BookLive, honto, Rakuten Kobo, au Book Pass, Reader Store, DMM Books, Comic Cmoa, LINE Manga, ebookjapan, Piccoma, and U-NEXT. The promotion is timed to the new Sgt. Frog anime, which begins airing Saturday, October 3, 2026. The manga has run in Monthly Shonen Ace since 1999 and is still ongoing. It follows an alien frog from Planet Keron who arrives to invade Earth, is captured by the Hinata siblings Fuyuki and Natsumi, and ends up living with the family as a lodger. A theatrical anime screened in June 2026. The fair notes that store end times, prices, and eligible products may differ by retailer.","whyItMatters":"Kadokawa is using a two-day, all-35-volume giveaway to push readers through the entire back catalog before the October 3 premiere, a distribution tactic that treats the manga run as marketing for the broadcast rather than a separate product.","webCardHtml":"\u003cp\u003eThe fair is called \u0026#34;Right Before the Anime! Sgt. Frog - Read It All, sir\u0026#34; and runs only two days, October 1 and October 2, 2026. Kadokawa is positioning it as a catch-up window for readers who want the whole invasion story in hand before the TV anime starts on October 3.\u003c/p\u003e\u003cp\u003eYoshizaki\u0026#39;s manga has been serialized in Monthly Shonen Ace since 1999 and remains ongoing, so the free set covers volumes 1 through 35 rather than a completed run. The premise has the title character arriving from Planet Keron to conquer Earth, getting caught by the Hinata siblings, and settling in as a lodger with the family. The first anime series aired from 2004, and a theatrical anime screened in June 2026, roughly 16 years after the previous film. The free period closes at 23:59 on each of the two days, and Kadokawa notes that end timing, sale prices, and eligible products can vary by store.\u003c/p\u003e","blueskyPost":"All 35 volumes of Sgt.
