Rinka Kagurazaka (神楽坂 りんか Kagurazaka Rinka) is one of the two main protagonists of Valkyrie Drive Bhikkhuni. She is the oldest of the Kagurazaka sisters who constantly smiles and has a gentle disposition at heart, her sheer rampaging prowess born from her pure heart strikes fear even in the heart of her younger sister. She fights with a katana (Tachi) that leaves a very nice scent in her tracks as she moves. Her sword also transforms into an upgraded, ancient-like sword when she kisses anybody that will perform a drive with her.

On the surface, most Rinka would be seen as a very kind woman who cares for her sister and loves making friends.

Rinka can also be quite stubborn especially when she becomes curious. Once she commits to something, nobody can stop her.

When Rinka is fighting, however, this kindness is forgone and is shown to be very aggressive with a katana due to the Virus. Ranka even points out that Rinka tends to be more aggressive with a katana than with any other weapon.

Ranka Kagurazaka (神楽坂 乱花, Kagurazaka Ranka) is the other protagonist of Valkyrie Drive Bhikkhuni. She is the younger of the Kagurazaka sisters. Determined and whimsical, Ranka is a hot-blooded girl who stands out thanks to her boyish behavior. She fights with her fists and goes head-first into battle. Both she and Rinka Kagurazaka (Ranka's older sister) are very sensitive when it comes to their bodies being touched. Her weapons are two huge beast-face gauntlets after she kisses anyone that can perform a drive with her.

Ranka is a hot-blooded girl with a tomboyish behavior. And thanks to her personal behavior, it makes her a powerful Valkyrie, one that's hard to take down. She's always fired up for a battle and will defeat anyone or anything no matter what it takes. But turns out she's not always like that. She actually has a caring and protective side of her. Like how she cares about her sister. She cares about her sister more than anyone else, and she would do anything she can in order to protect her from anyone or anything that can harm her.
