Pop is Doremi's younger sister. She's a lot more confident and efficient than her sister, since she progresses a lot faster than Doremi in the witch exams. Besides that, Pop also seems to have a lot of dates, asking Doremi how's possible that at this age she still doesn't have a boyfriend.

Pop likes to say she's mature, but in fact, she's still a young kid. Because of that, she often can't go to her exams because she often falls asleep.

She has a good relationship with Onpu, probably because their personalities are so similar.

Pop's birthday is September 9, her favourite color is red, and her instrument is the trumpet even though she plays the piano.
