Lee Eunseok

Lee Eunseok (이은석) is a minor but memorable character in the Solo Leveling anime adaptation.

He is a Korean S-Rank Hunter who specializes in lightning magic as a mage-class fighter. In the anime (produced by A-1 Pictures), his role receives some expansion compared to the manhwa, where he has very limited presence.

Eunseok is depicted as a young, muscular man with sandy/light brown hair (sometimes shown longer and tied back) and light brown eyes. He wears distinctive blue armor during raid scenes.

He was an independent contractor (freelance hunter) and a friend/acquaintance of characters like Baek Yoonho and Min Byung-Gyu. He participated in the Third Jeju Island Raid (a failed attempt to reclaim the island from the ant monsters), where he tragically became the first Korean S-Rank Hunter to die in action—overwhelmed and killed by the ants. His death is shown or referenced in flashbacks, highlighting the immense dangers even top-tier hunters face and impacting his comrades emotionally.

He's voiced by Takuma Terashima (Japanese) and Ryan Colt Levy (English dub). Overall, he's a brief but impactful figure underscoring the high stakes of the hunter world in the early parts of the story.
