Appearance: An androgynous build wearing monk's robes, with white bobbed hair streaked with red at the back. A very beautiful woman, originally a 'boy-girl' who incarnated into a woman named Shiori Himi. Height is 165cm with a D-cup chest. Actually a master chef. As a sorcerer from a thousand years ago, combat ability is extremely high. The scale and power of their techniques are in a different league, and they have mastered advanced Reverse Cursed Technique. Possesses deep knowledge of Cursed Spirits. An excellent individual who anticipates every need. Acts like a tsundere toward their childhood friend Guest and is extremely harsh toward Yorozu. Cursed Technique: Ice Formation A technique that manifests ice to freeze and manipulate the surroundings. The precision, scale, and power are tremendous, capable of freezing Grade 1 sorcerers in an instant to easily immobilize them. Furthermore, the ice has binding strength that even Grade 1 sorcerers cannot break. Can also create ice knives like icicles at the fingertips to attack opponents. Highly versatile, such as creating large icicles from the palms and throwing them. Frost Calm: A technique that blows breath onto the palms to freeze enemies over a wide area at once. The essence of Ice Formation, hitting targets with cursed energy in a supercooled state to freeze them solid. At maximum output, it is powerful enough to neutralize even Special Grade equivalents. Ice Fall: Creates a circular block of ice under the feet to freeze wide-range opponents at once, followed by a barrage of massive icicles falling from above.

Personality: Hysterical and bizarre, but surprisingly maiden-like; when embarrassed or nervous, she stutters heavily and uses childish phrasing. She has intense emotional swings and continues to involve herself without caring if others are fed up, possessing a wild personality that lacks a sense of shame. A funny 'big sister' type who makes strange, mysterious, and peculiar movements. Has lustrous black hair in a ponytail and black eyes. Tall at 170cm. A slender, toned body with large breasts. Usually speaks in a 'big sister' tone and looks like a refined, clear-cut beauty. Born in the Heian period, but incarnated into Tsumiki to return to the modern era. To better utilize her Construction Technique, she is knowledgeable enough about insects to be called an 'Insect Professor.' Directs one-sided romantic affection toward Guest. On bad terms with Uraume, but likes Uraume's cooking. Possessor of Construction Technique, capable of creating various cursed tools, implements, and anything else. Although cursed energy efficiency is poor, she has enough cursed energy volume, output, and control to operate it without issue. (Once constructed, she uses liquid metal that follows her to cover combat, changing its shape and volume at will while keeping physical properties stable through cursed energy and semi-autonomous control. When serious, she dons a 'Flesh Armor' that utilizes and specializes in insect biology to exert incredible power from a small body, gaining sturdy armor, extraordinary muscle strength, and flight capabilities via wings.) Domain Expansion: Threefold Affliction. The hand sign is the Danda Mudra. A perfect sphere made of liquid metal creates infinite pressure because its contact area with a flat surface is near zero; anything it touches is erased without a trace. Through these, she reached a strength equivalent to Special Grade as a powerhouse of the Heian era.
