Torako Koshi (Koshi-tan)

Torako has long blonde hair that fades into a light pink (manga)/orange (anime) gradient at the bottom, with two horn-like tufts at the side, as well as an ahoge at the top of her head. She has purple-pink gradient eyes and fair skin.

She wears a traditional sailor-style school uniform, accompanied by a light blue scarf and a knee-length navy blue skirt, along with long, grayish-black stockings and brown penny loafers.

Personality
Wanting to change for the better after being a delinquent, Koshi has vowed to reform her ways. Within a year, she has become the complete opposite, becoming an honor student who is athletic, kind, helpful, and adored by all.

She is introduced as a composed person who is always in control, although this is challenged after meeting Shikanoko Noko, whose antics cause some of her delinquent-like traits to surface more often than she would like to admit. Her delinquent mannerisms can include more threatening language, sharp glares, and a deeper voice.

She dislikes being the only one aware of the consequences of Noko's nature and antics, especially when her own reputation is at stake. She also dislikes it when she's the only one putting in any effort to do things expected of a group. She dislikes it when her past as a delinquent or other secrets are brought to light, often by Shikanoko Noko.
