She focuses more on fashion and romance than classes, but she isn't a delinquent. She seems to have given up on studying, but seeing how quickly her mind works in crises, it's more that she lacks interest rather than ability. Her trademarks are a choker and large hoop earrings; she wears the choker even while sleeping, with the decorative part turned to the back of her neck. She has a very classic taste in men and is a massive fan of actor Ken Takakura. She swoons just hearing his name or famous lines.

She uses psychokinesis, manifesting large, transparent green hands that are invisible to most. She has brown bobbed hair and crimson eyes. She believes in ghosts but not aliens.

She especially acts sweet toward otaku boys to get their attention.
