[Kagemusya] Arima-kun to 40-nin no Classmate

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.

Twintails (ツインテール) is a hairstyle tag referring to hair tied in two pigtails. This is a popular character design element in anime and manga, often associated with tsundere or energetic characters. The hairstyle has a dedicated following and is used as an aesthetic preference filter. Related hairstyle tags include 'ponytail,' 'short hair,' and 'long hair.'

Ponytail (ポニーテール) is a hairstyle tag referring to hair tied back in a ponytail. Like 'twintails,' this is a character design preference that readers use as a filter. Ponytails are often associated with sporty, active, or mature characters. Related tags include 'twintails,' 'short hair,' and 'long hair.'
