2025 has proven to be quite a heated year for anime, with tons of competition stemming from some absolutely sensational series. At the beginning of the year, Solo Leveling dropped its second season, which saw worldwide acclaim and even won the title of Anime of the Year at the Crunchyroll Awards for its first season. Solo Leveling’s success can’t be underestimated, but it’s still far from the biggest series in 2025 overall.

While Solo Leveling is massively popular, the biggest anime series of 2025 has revealed itself to be none other than Demon Slayer. Its Infinity Castle movie has done absolutely astounding numbers and even secured the anime a new award—the International Animation Award. This is a great achievement for the franchise, showcasing how big Demon Slayer has become over the last few years and how it'll continue to grow, especially with the release of Infinity Castle Part 2 and Part 3 in the next few years.

Earlier this year, a very tough battle was fought at the Crunchyroll 2025 Awards. 2024 saw the release of some of the most amazing anime, including the likes of Frieren, The Apothecary Diaries, and Dandadan, among many others. But only one anime came out on top, and not only did it win the title of Anime of the Year but it also swept other awards away. Fans know this anime to be Solo Leveling, the hottest new anime series. Solo Leveling has been dominating the whole year, especially with the massive success its second season brought on top of the already existing hype.

However, one series quickly toppled it with its new release, and that's none other than Demon Slayer. Demon Slayer released the hottest movie of the year, Demon Slayer: Infinity Castle Part 1 - Akaza’s Return. This movie broke all records in Japan, and now, it has even won a major award. Demon Slayer: Infinity Castle was awarded the International Animation Award. This accolade was earned by Demon Slayer at the Critics' Choice Awards 2025.

Demon Slayer might have hit the jackpot with Infinity Castle Part 1, but the series is only going to get bigger from here on out. While Part 1 of Infinity Castle was big, it will be overshadowed by the two major future releases of the series—Infinity Castle Part 2 and Part 3. These two movies feature even bigger battles and even more tragedy. The final movie, especially, is sure to reach new heights as it drops the curtain on the series forever.
