Cassaca is a strange girl with a real tail who seems to live near the Kamijou house. Her left and right eyes are different colors and she easily picks up the phrases she reads in manga or hears on TV. As a result, her speech is a mess and she may speak in a dialect one day, like an Edo-period prostitute the next, or like a guy some other day.
