Get Ready for an Anime Marathon on ABEMA!
Mark your calendars, anime fans! ABEMA, that cool “future TV” streaming service, is kicking off a huge event called the “Year-End and New Year Anime Free Mass Release Festival.” As part of this fest, they’re doing free marathon streams of some of the biggest and longest series out there. Starting from Friday, December 26, 2025, you’ll be able to binge-watch over 300 titles without spending a yen. Talk about a way to ring in the new year!
What’s On the Free Binge-Watch List?
This event is really focusing on those epic, long-running stories we all love to get lost in. Leading the pack is the massively popular isekai fantasy Re:Zero kara Hajimeru Isekai Seikatsu (you might know it as Re:Zero -Starting Life in Another World-). They’re streaming everything from the 1st season all the way through the 3rd season, plus the related works “Memory Snow” and “Hyōketsu no Kizuna” (The Frozen Bond).
Also getting the non-stop treatment is the emotional sci-fi saga STEINS;GATE. Follow Rintarou Okabe as he battles fate through time leaps. And it’s not just the main story; you can also dive into the alternate world line of STEINS;GATE 0.
But wait, there’s more! The lineup is stacked with six heavy-hitting series in total. Get ready for laughs with Kono Subarashii Sekai ni Shukufuku o! (KonoSuba: God’s Blessing on This Wonderful World!) seasons 1 through 3. Then, gear up for the epic journey of Tate no Yuusha no Nariagari (The Rising of the Shield Hero) from seasons 1 to 4. Virtual reality adventures await in Sword Art Online, and you can witness the supreme rule of Ainz Ooal Gown in Overlord.
The best part? After each series starts streaming, you’ll have a full two weeks to watch every single episode for free. Whether you’re a first-timer curious about the hype or a veteran wanting to relive the best moments, this is your perfect chance for a guilt-free binge session.
ABEMA’s “Year-End and New Year Anime Free Mass Release Festival” is packing more than just these series. With over 300 titles, including new anime, classic long-running “王道” (oudou) series, and the latest seasons of shows continuing into 2026, the ABEMA anime channels are the place to be this winter.
