[Amuai Okashi Seisakusho (Sasanoma Nibi)] Fallen Sister! What She Wants Isn't a Boyfriend but a Cute Little Sister

Big breasts (巨乳, kyonyu) is one of the most iconic body-type tags in doujinshi and manga. It refers to female characters with notably large, exaggerated breasts that often serve as a central visual element. Artists typically emphasize size, weight, jiggle physics, cleavage, and breast-focused activities like paizuri (titjobs) and breast play. This tag spans nearly every genre — from vanilla romance to hardcore fetish content. The artistic treatment varies widely: some artists favor realistic proportions while others push into exaggerated territory. Related body-type tags include 'huge breasts' for extreme cases, 'small breasts' for the opposite aesthetic, and 'paizuri' for breast-focused sexual acts. The tag often appears alongside 'sole female' and 'nakadashi' in heterosexual content.

Lolicon (ロリコン) refers to content featuring young or young-appearing female characters. In doujinshi context, this tag indicates the presence of petite, youthful female characters. The term originates from 'Lolita complex' and is a significant demographic category in Japanese fan-made works. Content with this tag ranges from suggestive to explicit. It frequently appears alongside tags like 'small breasts,' 'defloration,' and 'schoolgirl uniform.' The tag is distinct from 'shotacon' which features young male characters.

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.
