Rizu Sex | Uglymug, Epicfighter

Rizu is one of the supporting characters in the isekai / fantasy series Uglymug, Epicfighter (Japanese: Busamen Gachi Fighter). (Wikipedia) In the anime adaptation, Rizu is voiced by Maaya Uchida. (Crunchyroll)

In the lore of Uglymug, Epicfighter, the main protagonist is Shigeru Yoshioka, a man who was falsely accused of a crime in his original world, became a recluse, and then is transported to another world via a game-like “status screen” mechanic. (Wikipedia) In that new world, Shigeru gives up his looks and imposes severe penalties on himself (for example, touching female skin causes him damage; engaging in sexual acts could be fatal) in exchange for enormous stat boosts and power. (AniDB)

Rizu’s role in this story is somewhat mysterious in public sources. According to one fan forum, it’s said that Rizu knows Shigeru from her past life/world due to a “special note.” (FanVerse) That gives Rizu a hidden connection to the protagonist’s backstory. In some retellings, she is said to have “sealed two of her desires, sex and sleep,” which suggests that, like many characters in this series, she may have limited or sacrificed personal needs or freedoms to gain power or autonomy in the new world. (FanVerse)

Rizu’s presence adds a layer of intrigue. Because she is cast by a well-known voice actress and announced as part of the main cast, she is likely more than a throwaway character. (Crunchyroll) She may act as an ally, rival, or someone whose true motives are gradually revealed. Her being tied to the protagonist’s past gives potential for emotional conflict, shared history, or hidden betrayal.

Given the severe restrictions and penalties in the world of Uglymug, Epicfighter, relationships, trust, and interactions with the opposite sex are fraught with danger. Shigeru’s “female allergy / damage on contact” penalty means that any female character must be handled carefully in the narrative, so Rizu’s interactions with him likely carry tension, emotional weight, and mystery. (AniDB)

Visually and character-wise, details are sparse in the public domain (at least in English sources). Because the manga and web novel have limited translation coverage, dedicated fans or official materials may have more complete descriptions of her appearance, powers, personality, and relationships.

In summary, Rizu is a supporting but important character in Uglymug, Epicfighter, connected to the protagonist’s past, with hints that she made significant sacrifices (in desires) to obtain abilities or influence. Her secretive background, and her voice casting, suggest she may be a pivotal figure as the plot develops.
