Kasuga was sent on a mission to kill Uesugi Kenshin. However, when she had her target in sight, Kasuga fell in love with Kenshin. After failing to assasinate Uesugi she was banished from her village. From then on Kasuga served Kenshin and became his most loyal ninja. She takes her duties seriously, and due to the Kenshin's battles with Takeda Shingen (as well an implication that they are from the same ninja village) a rivalry grew between Kasuga and Sarutobi Sasuke. Additionally, the two ninja have opposite elements.
She is often seen as having a rivalry with Nouhime as well, due to the other woman's role as Nobunaga's love interest and protector, and their similar personalities.
Kasuga although is very beautiful, she is noted to have a very sexual appearance, with a skin-tight body suit that's open very low in the front, baring half of her breasts and some of her legs.
Role in GamesEdit
In Sengoku BASARA 3, Kasuga only appears in one stage (unless selected as an ally). In the Battle of Kawanakajima-Tundra, after the player defeats Keiji the first time and Kanetsugu Naoe, she will appear at the North-West side of the battlefield, opposite from a returned Keiji. As you fight her, she has unique lines for each character but will promise Kenshin's protection at least once. After her defeat, her lines presume she retreats instead of dies, with the exception of when you're fighting as Ishida Mitsunari. Once she and Keiji have both been defeated, Kenshin appears on the battlefield.
Kasuga is a playable character in Sengoku Basara 1 & 2. She is demoted to NPC for Sengoku Basara 3, but is made playable in Sengoku Basara Utage. In this expansion, she does not have her own story, but appears once again in Kawanakajima-Tundra, as well in the Kyoto Fireworks Festival stage alongside Keiji. The player can unlock her for Free Mode and Unification Mode by clearing the stories of Sarutobi Sasuke or Muneshige Tachibana.
In Sengoku Basara 1 she wields two small ringblades in Sarutobi Sasuke's style, but in later titles, she wields two pair of four kunai attached by a wire. In Sengoku Basara 3 Utage, her personal item allows her to bind enemies with the wire. Like Sasuke, she can glide down using an owl familiar.
