Ryomou Shimei (呂蒙子明) is a playable crossover DLC character in the Senran Kagura: Peach Beach Splash. She originally comes from the series known as Ikkitousen.
Ryomou is a beautiful girl with short dark blue hair, she also wears a modified eye patch. She is usually seen wearing her highschool uniform, with a plad skirt and a brown blouse, or her iconic blue French maid outfit.
She is shown to be a sadistic person, enjoying ripping her own teammates arms until they are broken. For the majority of the time, Ryomou is more reserved and stoic in how she presents herself.
However, it is revealed later on that Ryomou had a softer side, until her friend Teifu was left blind and in a wheelchair. After befriending Sonsaku, she (while still serious) managed to loosen up slightly.
Ryomo is one of the main characters of Ikkitousen (Battle Vixens in NA). She, Teifu, and Saji have been best friends long before the start of the series. Ryomou is in love with Saji and cares for Teifu (who loves her). She is one of Nanyo's big four, ranking in at least second strongest, right behind Saji. She is specializes in submission techniques: moves, throws, and joint attacks which she often uses with a pair of handcuffs she carries.
- Ryomou is Saji's second girlfriend his first being Ryofu.
