Touko Hio

Touko Hio (氷尾 凍子) is one of the caretakers of Ayaka Kagari in middle school along with Kanae Hozuki. They helped her to interact with society. She was the student council vice president until Honoka Takamiya replaced her. After it she became vice-vice president. She never questions Ayaka directly.

Appearance
Touko is a girl of average height but of voluptuous build. Her hair is ice blue and curled at the ends. She has brown eyes.

She is usually clad in her school uniform, though she's also seen in several other outfits, usually her work uniforms from her various part-time jobs.

Personality
Touko is a very energetic, polite, and caring girl. Unlike many others who were jealous or spiteful towards Honoka due to his relationship with Ayaka, Touko was very supportive and considerate. She is very fond of Ayaka despite Ayaka's cold attitude towards her.

Background
Few years prior to the main timeline, Touko and Kanae were appointed by Kazane Kagari to take care of Ayaka Kagari, who is a seemingly frail child who doesn't know anything about social life. Letting Kanae keep noticing Ayaka like a manager, Touko managed to be silent and enjoy it. Then, Ayaka goes to the male division of Tougetsu Junior High, questioned by Touko and Kanae, yet she said nothing about it and keep peeping for a whole year, and Ayaka finally reacts when she found "him," yet Touko seemingly didn't realize a thing...

Powers and Abilities
Touko is an ice-manipulating witch. Just from a mere touch she can freeze objects. Like Ayaka, she also can manipulate the temperature around her. Interestingly, Touko's power increases in proportion to threat. When she is placed in mortal danger her power skyrocketed, she could create a massive cold front that enveloped all of Tougetsu City.

Trivia

 * Despite of Touko always using her power around Honoka, Honoka is yet to notice her powers.
