She is Headmistress Jeanne Ψ, an alter ego of principal Ms Yuki who is much more cruel and punishes students often. Her punishment is still tying you up and swarming you with kisses, but now there's a whip so it's closer to BDSM. In contrast to Ms Yuki's soft blue hair, Jeanne Ψ's hair is a deep crimson, and she is still as attractive as ever. She can transform between Principal Ms Yuki and Headmistress Jeanne Ψ at will. Everyone still desires her punishment.
