Cha Hae-In

Cha Hae-In is an S-Rank hunter and Vice-Guild Master of the Hunters Guild, renowned for her skill in swordplay and a unique olfactory sensitivity that makes other hunters smell foul to her. As a naturally powerful fighter from a young age, she initially felt isolated but later learned the value of teamwork from Sung Jin-Woo, who is the only person she perceives with a pleasant scent. She became an S-Rank hunter two years prior to the main storyline and swiftly rose to prominence as the Vice-Guild Master of the Hunters Guild. She possesses a condition that makes the mana of other hunters and monsters smell putrid to her. This changed when she met Sung Jin-Woo, who did not smell bad to her. Despite her immense strength as an S-Rank hunter, she is known to be diligent in training and respectful of lower-ranked hunters. Her initial solitary and intense focus on victory was softened after being saved by and connecting with Jin-Woo during the Jeju Island raid. In Solo Leveling: ARISE, a different version of her backstory is explored, where she is depicted as the "Pure Sword Princess" who learns the importance of teamwork and leads a team of hunters. She is considered a highly skilled, albeit sometimes socially awkward, character who values strength and camaraderie in combat.
