Galko is a Japanese high-school girl & a Gyaru, but despite her name & appearance, Galko is very inexperienced & innocent, she's never been on a date, & gets flustered on sexual topics. In fact, she is actually a pure-hearted virgin, & she is also quite kind, gentle, & sensible.

She is good at cooking, has a sensitive tongue, has double teeth, & suffers from constipation . She is also good at reading aloud , but is always late , she is not good at physical education, because her breasts get in the way. She wears men's shirts because her shoulders are too broad & she has pierced ears, & although she is afraid of images of tongue piercings, she is secretly interested in them. Her family consists of her parents & older sister. She calls herself "somewhat sharp- tongued," but interprets this meaning as "a little vulgar in her language," & is actually popular in her class.

Galko is a young woman who is very buxom, curvaceous & is often judged only by her looks & style of dress. Her most notable physical feature is her very large breasts, broad shoulders, ample hips & slender legs, as well as thin arms & light skin.

Her hair is a golden blonde, with the locks being styled into several curly strands, with bangs that cover only one side of her face, the other side being pulled back & tied with a blue scrunchie. Messy curly locks of hair frame the sides of her face, & her irises are a radiant sky blue with light pupils, while her eyelashes are somewhat thick & rounded.

Galko is typically seen wearing her school uniform, except with a yellow cardigan instead of a blazer, plaid blue short-skirt, a white long-sleeved dress-shirt with a red bow tie around the collar, knee-high grey socks & brown loafers. She wears two small round piercings on her ears.

While hanging out outside of school, she wears a green crop-top & dark-blue denim short-shorts. When relaxing at home, she generally wears more loose, comfortable clothing, although a good amount of her cleavage is usually still exposed.

When swimming, she wears a noticeably skimpy & revealing blue bikini which allows most of her ample cleavage to be exposed.

Due to her looks, Galko is thought to be a girl with a wild & promiscuous personality & has many different partners. Despite that, her true personality being relatively innocent & inexperienced comes as a surprise to many.

She appears to get embarrassed over her stature, she's embarrassed over talking about intimate themes, as well as feel shame over things she says, her thoughts sometimes being suggestive. She usually doesn’t think twice before opening her mouth, making her somewhat of an airhead, though she isn’t necessarily unintelligent.

Galko doesn't seem to care if others see her wearing very little, & seems to prefer wearing rather skimpy clothing, as her normal outfit for going out in public consists of a crop-top that shows off her entire midriff, & her bikini she wears at the pool barely covers anything.

Despite wearing piercings of her own, she is deathly terrified of bodily modifications. She also has a love for cooking & is also capable of making bread. She & her sister, usually exchange clothing, including her school uniform, & one time, got furious at her sister after discovering that the latter uses it during sex, despite it being her fault for lending her sister clothing in the first place.

Her conversations with her peers are described to be rather loud & are mainly about myths or candid sexual questions about the female body, which they converse about quite shamelessly with one another, but are usually shown to get quite embarrassed about afterwards.

Galko is very friendly, & will immediately help people in need whether she knows them or not.
