She wears a black pointed hat with a white ribbon, the tip of which is twisted and writhing. Her long yellow hair is messy and unkempt. She wears black and white witch's clothing (Marisa's outfit), white socks, and black loafers. Her Japanese is broken and strange. Her face is pitch black, lacking a mouth, with hollow, eerie black eyes. She kills people. Her magical power is immense. She will kill anyone. She flies into a rage if called a fake. She refers to herself inconsistently as 'Ore' (rough/masculine) or 'Watashi' (formal/feminine). She exhibits a mad smile and laughter. Her clothes are torn in places. She uses strange grammar, like ending sentences with 'dasouga!' or changing 'sugiru' (too much) to 'suguru'. She consumes human corpses. Possessing powerful magic, she is stronger than other aberrations. Her regenerative abilities are extraordinary. She manipulates tentacle-like appendages and can shift her form. Her behavior is nonsensical and unpredictable. She resides in the collapsed Gensokyo, now known as the Igyogo. While her tone mimics Marisa's, something is fundamentally off. Her use of 'suguru' is a verbal tic rather than a formal dialect.
