[Shihai Shoujo (Dining)] Medaka The End (Medaka Box) [English] [J-Eye]

Anal intercourse is a common sexual act tag in doujinshi. It appears across nearly all genres and demographics, from vanilla romance to extreme fetish content. The artistic depiction ranges from realistic anatomy to highly stylized presentations. This tag frequently co-occurs with tags like 'nakadashi' (internal ejaculation), 'big breasts,' and various body-type tags. Some artists specialize in anal content, developing signature techniques for depicting the act. The tag covers both consensual and non-consensual scenarios depending on accompanying tags.

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.

Sex toys (オナホール, バイブ) is a fetish tag covering the use of various adult toys in doujinshi. This includes vibrators, dildos, fleshlights, and other devices. The tag covers both solo use and use during partnered scenes. Artists often use toys to add variety to scenes or to depict specific fetish scenarios. Related tags include 'masturbation,' 'dildo,' and 'vibrator.'
