Also known as Venus, she is a skilled ninja in the game Sengoku Basara.
Kasuga serves the Uesugi clan. She takes her duties seriously, and also makes rivalries with Nōhime (regarding on those they protect) and Sarutobi Sasuke (ninja rivalry). Due to her outfit and mannerisms, she is regarded as the game's sex symbol. Kasuga wields two small ringblades, but in Sengoku Basara 2, she wields eight kunai (four on each hand) tied with invisible razorwire.
Her name may be come from Kousaka Masanobu's former name Kasuga Toratsuna.
