Kei

Kei is a Japanese S-Rank Hunter in the anime adaptation of Solo Leveling, affiliated with the Draw Sword Guild (also referred to as the Blade Guild in some translations). He specializes in ice magic, demonstrating powerful abilities such as rapidly creating large walls or barriers of ice.

He participates in the high-stakes Jeju Island Raid as part of the international support team. Kei has an extremely sensitive sense of smell (similar to Cha Hae-In), particularly toward mana, which causes him discomfort around other hunters or monsters—so he often wears a mask to filter it out.

In terms of appearance (as shown in the anime), he's depicted as a young man with short white hair, purple eyes, and thin eyebrows, giving him a distinctive, somewhat ethereal look among the hunters.

His role highlights the international cooperation (and tensions) during major raids, though his screen time focuses more on his combat utility and tragic fate in that arc rather than deep personality exploration.
