Overly Self-conscious Girl

The Overly Self-conscious Girl (OSG) is a student of Sanada Central High and an acquaintance of Yassan.

Appearance
The OSG is short and slim, with short brown hair. Her build and hairstyle resemble that of Ringo's, except that she has lighter-colored hair and eyes, and has no blush on her cheeks. She is usually seen wearing the Central High uniform.

Personality
Like her epithet suggests, she is extremely self-conscious. She almost always overthinks in response to the slightest things, especially when around boys.

After her encounter with Hidenori on the riverbank, she picks up a sadistic streak in tormenting boys similar to what he did to her. This is short-lived, however, when Yoshitake gives her a taste of her own medicine in the train and devastates her. Eventually, she resumes her normal demeanour where she pays little to no attention to others.

In hindsight, she is more or less a female version of Mitsuo, known for his extreme bad luck.

High School Boys and the Literary Girl 4
In the OSG's first appearance, she sits down near the riverbank after school when Hidenori accidentally sat behind her, too close for comfort. Once Hidenori realized her presence and his mistake, he initially planned to talk to her before deciding to abruptly leave instead, shocking her. In the end, she got chased off by Yassan, who is angry for causing Hidenori to leave.
