[Okano Hajime] Escape (Onee-san ga... Shite Ageru) [English] [sirC]

Schoolgirl uniform (セーラー服, sailor fuku / 制服, seifuku) is a costume tag that's deeply embedded in Japanese manga and doujinshi culture. It refers to the iconic Japanese school uniforms — either the sailor-style (sailor fuku) or blazer-style (seifuku). This tag is significant because school settings are a common backdrop for many genres, from romance to fantasy. The uniform itself has aesthetic appeal in illustration, and artists often use it as a visual shorthand for youth and innocence. It frequently appears alongside 'lolicon,' 'sole female,' and various school-themed parody tags.

Shotacon (ショタコン) refers to content featuring young or young-appearing male characters. The term originates from 'Shotaro complex' (after the character Shotaro from Tetsujin 28-go). In doujinshi, this tag indicates the presence of youthful male characters in suggestive or explicit scenarios. Content ranges from innocent to explicit and is a significant demographic category. The tag is the male counterpart to 'lolicon' and often appears in yaoi (male-male) content or in heterosexual scenarios with older female partners.

Defloration (処女喪失) refers to content involving the loss of virginity. In doujinshi, this often serves as a narrative milestone and is depicted with varying degrees of realism. The tag covers both first-time experiences and the physical aspects of virginity loss. It frequently appears alongside tags like 'sole female,' 'nakadashi,' and various romance or school-themed tags.
