Warabi Hanasaka enforces authority as part of the Supreme Five Swords, an elite group overseeing discipline at a private academy. A practitioner of Taisha-Ryū, she seamlessly blends swordplay, hand-to-hand combat, and shurikenjutsu into her dynamic fighting style. Her striking appearance features long blonde hair secured by a pink bow, a petite build, and a deceptively youthful face. She dons a white sleeveless shirt paired with a maroon tie, a blue skirt, a dual-toned cape, and knee-high silver boots, her katana always sheathed at her left hip.

Renowned for blinding speed and agility that outpaces even fellow swordsmaster Rin Onigawara, she executes precise spinning slashes, aerial assaults, and swift defensive blocks using her katana’s guard. Shuriken and concealed blades extend her arsenal, deployed with unerring accuracy mid-battle. Enhanced physical prowess fuels her fluidity in combat, enabling relentless mobility during intricate attack sequences.

Boisterous and theatrically inclined, she punctuates interactions with raucous laughter and crafts elaborate spectacle-driven contests dubbed "Warabinpics" to challenge rival Nomura, favoring flamboyant rivalry over straightforward clashes. This penchant for drama extends to eccentric choices, such as forgoing underwear beneath her yukata during an OVA hot springs escapade. Her confrontations with Nomura prominently showcase her competitive zeal and martial mastery, though her origins and personal history remain undisclosed in extant records.
