MILF (Mother I'd Like to Fuck) is a character type tag referring to mature female characters, typically mothers or maternal figures. In doujinshi, this tag indicates content featuring older women, often contrasted with younger male partners. The appeal lies in the experience and confidence of the character. The tag frequently appears alongside 'big breasts,' 'incest,' and 'sole male.'

Tankoubon (単行本) indicates that a gallery is a compiled volume or collected edition. Unlike magazine serialization, tankoubon are standalone books that collect chapters or are complete stories. This tag helps readers identify the format of the work. Tankoubon typically have higher production values and more cohesive narratives than magazine chapters.

Story arc indicates that a gallery is part of a multi-chapter narrative. Unlike 'multi-work series' which can be any collection, 'story arc' specifically indicates a continuing storyline with plot progression. Readers looking for narrative-driven content use this tag to find works with developed storylines.
