[CHRONOLOG] Little Little Happiness

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.

Collar (首輪, kubiwa) is a costume/accessory tag indicating characters wearing collars, often in a BDSM context. Collars symbolize ownership or submission in kink scenarios. The tag covers both decorative collars and functional bondage collars. It frequently appears alongside 'bondage,' 'femdom,' and 'pet play.'

Kemonomimi (獣耳, animal ears) refers to characters with animal ears (and often tails) while otherwise appearing human. This includes catgirls (nekomimi), fox girls (kitsunemimi), dog girls, and other animal-eared characters. The tag is a significant character design category in anime and manga. Related tags include 'catgirl,' 'fox girl,' and 'monster girl.'
