Also known as Venus, she is a skilled ninja in the game Sengoku Basara.
Kasuga is a loyal member of the Uesugi clan and takes her duties seriously. She has rivalries with Nōhime and Sarutobi Sasuke, mainly concerning the people they protect. Despite her outfit and mannerisms, she is often considered the game's sex symbol. Kasuga uses two small ringblades as weapons, but in Sengoku Basara 2, she switches to eight kunai, four on each hand, tied with invisible razorwire.
Her name may have come from Kousaka Masanobu's former name Kasuga Toratsuna.
