[Hitsumabushi] Futanari Maki-chan Kaiyou Seibutsu-hen (Japanese, English)

Multi-work series indicates that a gallery is part of a larger collection of related works. These are typically chapters or parts of an ongoing story, character series, or thematic collection by the same artist. Readers looking for complete narratives can use this tag to find connected works. The tag helps distinguish standalone doujinshi from serialized content.

Futanari (ふたなり) refers to characters with both male and female sexual characteristics — typically female-presenting characters with a penis. This is a significant genre in hentai with its own dedicated audience. The tag covers a wide range from characters with both sets of genitalia to characters who are essentially female with male genitalia. Artistic treatment varies from realistic to highly stylized. Related tags include 'males only' (for futanari-only content) and 'yuri.'

Tentacles (触手, shokushu) is a genre tag covering tentacle monsters and their interactions with characters. This is a distinctive genre in hentai with roots in Japanese horror and fantasy art. The tentacles can range from realistic sea creatures to fantasy monsters. The genre often features non-consensual scenarios and is closely related to 'monster' and 'rape' tags.
