Kiko, an orphan from Shinobiyama, trained vigorously and excelled at swordsmanship. Under Master Nakamura's mentorship, she honed her skills, incorporating kenjutsu and fire techniques into her fighting style. Her primary approach involved rapid, aggressive sword strikes. After mastering the "Crimson Whirlwind" technique, she left to spar with other swordfighters to further improve her skills. Kiko's smug yet positive attitude remained her defining characteristic.
