[Shimoya] Isekai Jigoro ～ Tenseisaki de Joseimuke Fūzokuten Hajimemashita ～1

Sole male indicates a gallery features exactly one male character. Combined with 'sole female,' this creates the classic one-on-one pairing. With multiple female characters, it creates a harem scenario. This tag is useful for filtering based on the reader's preferred dynamic — whether they want focused monogamy-style content or one male with multiple partners. The tag doesn't specify the male character's role or prominence; he could be the protagonist, a side character, or even a reluctant participant depending on the genre.

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.

Kissing (キス, kisu) is a romantic/sexual act tag covering various types of kisses. While seemingly simple, kissing scenes in doujinshi can range from tender romance to intense passion. The tag helps readers find content with romantic elements rather than purely physical encounters.
