Every year, a new popular anime dominates the entertainment landscape and finds itself on the watchlist of every fan. In 2020, it was Jujutsu Kaisen; in 2023, it was Frieren: Beyond Journey’s End; and in 2025, it is Solo Leveling Season 2. While the first season was equally as popular, the second season ramped up the action, intrigue, and animation, making it a must-watch action anime of this decade and in general.
