AceShowbiz - The anime world has witnessed the meteoric rise of Solo Leveling in recent years, becoming one of the most talked-about sh?nen series with its straightforward approach to action and power fantasy. However, in 2026, another heavyweight contender is poised to challenge its dominance: That Time I Got Reincarnated as a Slime. This franchise will return with its highly anticipated fourth season and a new feature film, both expected to make a significant impact on the anime landscape.

Solo Leveling has enjoyed immense popularity, thanks largely to its clear-cut narrative focused on thrilling combat sequences rather than complex storytelling. The series follows Sung Jin-woo, once the world's weakest hunter, who gains extraordinary powers after surviving a deadly monster attack. This transformation leads him on a journey filled with some of the most exhilarating fights in anime history. One standout moment is Jinwoo’s epic battle against the Ant King near the end of the second season, a sequence that has garnered over 30 million views on YouTube, reflecting the show’s widespread appeal.

Despite the widespread acclaim and fan fervor surrounding Solo Leveling, the upcoming return of That Time I Got Reincarnated as a Slime could shift the balance in the isekai genre. Known for its inventive premise and expansive world-building, the series centers on Rimuru Tempest, a salaryman reincarnated as a slime—the weakest creature typically found in fantasy worlds. Defying expectations, Rimuru grows to become one of the strongest beings, establishing his own nation and altering the world in unprecedented ways.

After a two-year hiatus, That Time I Got Reincarnated as a Slime is slated to resume its story with Season 4 premiering on April 3, 2026. Shortly after, on May 1, the franchise will release a new movie titled That Time I Got Reincarnated as a Slime the Movie: Tears of the Azure Sea. This film continues the saga with Rimuru and his companions invited by Celestial Emperor Elmesia of the Magi Dynasty Thalion to a private resort island. However, their respite is interrupted by a mysterious new character named Yura, setting the stage for fresh adventures against the backdrop of the vast azure sea.

The return of Rimuru Tempest marks a significant moment for fans and the anime industry alike. With its blend of action, adventure, and fantasy, as well as its established fanbase, That Time I Got Reincarnated as a Slime is positioned to potentially eclipse even giants like Demon Slayer in popularity. The late 2010s and early 2020s have been defined by the isekai boom, and this series exemplifies the genre’s ability to explore limitless storytelling possibilities.

While Solo Leveling remains a powerhouse with its straightforward, adrenaline-fueled action and massive fan engagement, especially with scenes like Jinwoo’s battles, the ambitious new season and film of That Time I Got Reincarnated as a Slime signal a strong contender for the top spot in 2026. The franchise’s expansion into new narrative territory and its continued growth in fanbase suggest it is ready to dominate the anime scene once again.

In summary, although Solo Leveling has carved out a remarkable niche with its intense combat sequences and clear-cut storytelling, the upcoming releases from That Time I Got Reincarnated as a Slime promise to deliver an even more expansive and ambitious experience. The anime community eagerly awaits April and May of 2026 to see whether Rimuru’s return will indeed dethrone Jinwoo and capture the crown of the greatest isekai anime of all time.
