Edit
Vocamente Yuuko is a character in Heybot!. She is an alternate persona of Nejiyanagi Yuuko and a continuation of Furuido Yuuko. Like Furuido, she has black hair that covers one eye styled as a short bob cut, but is no longer monochrome. Like Nejiyanagi, she has green eyes. She is often depicted with a blush. Originally designed as the protagonist's childhood friend in high school, she wears a school uniform with a purple skirt, purple blazer, green necktie, white dress shirt, black thighhighs, and brown loafers. For some reason, she now lives in the series' version of hell and speaks in a faux broken Italian accent.
She also has a second form as a taller, older-looking teacher/demon-like character. In this form she has long hair and wears a blue skirt, pantyhose, black high heels, rimless cats-eye glasses, and a red demon horn hairband. She retains the white dress shirt.
