古仲 まひろ

Tsukasa's cousin and a teacher at St. Trea high school. She acts as his and his sister's guardian, and is called "Onee-chan" by Tsukasa and Hazakura.

She is a cool beauty with a mature body and a bewitching sex appeal.

In the real world, she can not express her feelings of Tsukasa in a straightforward way, so she comes off as distant.

While in the game world, however, she loves to be attacked by Tsukasa.

Her class while in the game is "Mahouhime" (Witch Princess).
