Tomoe hails from the eastern island nation of Hinomoto, where she served as a Warrior Priestess (Musha-Miko) at the ancient Masakado Shrine. Her order protected Hinomoto using elite sword skills and mystical talismans, prioritizing loyalty and decorum. A divine revelation from the shrine's high priest compelled her to cross the sea and compete in a mainland tournament, seeking the power necessary to save her homeland from corrupt rulers. She possesses long black hair, violet eyes, and a fit build, standing approximately 160 cm tall. Tomoe typically wears traditional miko attire, including a red hakama and headband. Initially, she wielded the sword Kushinada, capable of emitting a purple aura to enhance its power in dire situations. Her combat style blended precise sword techniques like the "Helmet Cleaver" (a powerful downward strike) with explosive ofuda paper talismans and melee kicks such as the "Warrior-Priestess Kick". After the tournament, Tomoe returned to Hinomoto and earned the title of Sword-Saint Priestess. However, an unknown entity afflicted her with a "Blindness Curse" during her travels, rendering her eyes devoid of color. This did not diminish her resolve. She adapted to blindness through heightened senses and spiritual awareness, often stating she "sees more clearly" without sight. Her attire evolved to include an additional robe and a second sword, with her headband strands lengthened symbolically. In later events, Tomoe continued defending Hinomoto with renewed dedication. Her design remained largely consistent, though her hair was sometimes tied in a ponytail with a red bow. She maintained her calm, modest, and chaste personality, often expressing discomfort at revealing outfits. Her relationships with allies like Leina Vance and Shizuka deepened; Leina taught her to bake green-tea flavored cakes, a skill she cherished. During the Vanquished Queens storyline, a goblin overlord captured Tomoe after targeting her group of shrine maidens. Imprisoned and subjected to torture alongside Nowa, she endured physical and psychological humiliation but refused to yield. Despite her blindness and the Swamp Witch's curse, she used her spiritual abilities to protect fellow captives and orchestrate their escape. This resilience highlighted her acceptance of her condition; she explicitly stated she would not seek a cure for her blindness, viewing it as part of her spiritual path. Her combat parameters evolved: in initial tournaments, she scored Attack and Potential highly (4/5) but moderately in attributes like Defense and Technique (3/5). Later assessments showed her Bravery and Popularity peaking (5/5), reflecting her legendary status, though her Potential decreased (2/5) as her skills plateaued. A special Vanquished Queens episode depicted an alternate scenario where she endured extended torture, reinforcing her unwavering commitment to protecting others under extreme duress.
