KING's RAID: Successors of the Will

King's Raid: Successors of the Will was produced by studio OLM and released in 2020 as an anime adaptation of the mobile role-playing game developed by Vespa. The series was designed to expand upon the game's established lore, focusing on a group of adventurers led by the knight Kasel as they embark on a quest to defend the continent of Orvelia from an encroaching demonic threat. This adaptation aimed to transition the high-fantasy aesthetic of the mobile game into a serialized narrative format, prioritizing character dynamics and expansive world-building typical of the genre.

The production process sought to honor the visual identity of the original game while adapting its mechanics into a linear story, a common approach for mobile-to-anime transitions. The series received a mixed reception, with viewers often noting the challenge of condensing the expansive, non-linear progression of a mobile RPG into a coherent 26-episode television arc. Despite the structural challenges, it serves as a distinct entry in the studio's portfolio of game-based adaptations, reflecting the era's trend of utilizing popular mobile titles as vehicles for expanded media storytelling.
