She is a cheeky piano spirit who lives in Takuto's piano and is only visible to him. She is able to change her appearance between a childlike form and and a more mature one and is seen controlling Takuto at times, changing his appearance and forcing him to play the piano. She first appeared to Takuto when he was a child.

Design
Schall has white hair in two long pigtails with lighter blue ends, with straight bangs topped by a dark blue section that gives them the appearance of piano keys. She wears a blue collar with a navy blue and white dress and thigh high stockings, one being light blue while the other is medium blue. Her eyes are dark and light blue.

In her younger appearance seen when Takuto was a child, she had shorter hair, short blue boots, and wore a dress similar to her current one, albeit looser and with the top part connected to the collar and no tattered bottom.
