Ato Kusharundo

Born as the third princess of the Kusharundo chieftain lineage, she initially disguised herself as a man and entered the battlefield in search of her elder brother. Believing Kainshell to be responsible for her brother's death, she once pursued him with vengeance in her heart. After the truth came to light and the misunderstanding was resolved, she shifted from enemy to ally, becoming his disciple. Later, upon suffering a fatal wound, she received Kainshell's fairy blood and was transformed into a demi-human, continuing to accompany him on his journey of revenge against the Seven Heroes.
