(C90) [AMAGI AN IRONWORKS (Ebisu)] HUBBY`S BLOCK!! 23 (Koutetsujou no Kabaneri)

Sole female indicates that a gallery features exactly one female character throughout the entire work. This tag is important for readers who prefer focused, intimate scenarios rather than group dynamics or harems. It doesn't imply anything about the number of male partners — a sole female gallery can feature one male partner (sole male) or multiple. The tag helps distinguish between different relationship dynamics and is commonly paired with tags like 'sole male' for one-on-one scenarios or 'multiple male' for gangbang-type content. In terms of narrative structure, sole female works often develop a single relationship or encounter in depth rather than juggling multiple characters.

Mosaic censorship (モザイク) refers to the pixelation or blurring applied to explicit content in Japanese published works. This is due to Japanese obscenity laws that require censorship of genitalia in published materials. The tag helps readers identify whether content is censored or uncensored. Many doujinshi are published with mosaic censorship and later 'decensored' by fans or released in uncensored versions by the artist. Related tags include 'uncensored' and 'full censorship.'

Rape (レイプ) is a content tag indicating non-consensual sexual activity. In doujinshi, this ranges from forceful scenes to fantasy scenarios. The tag is used for content where sexual acts occur without consent from one or more participants. It's important to distinguish this as a fictional content tag — all characters are depicted as adults in the artistic context. The tag frequently appears in darker genres and is often paired with tags like 'bondage,' 'mind break,' and 'dark skin.'
