The stupid author looked through Witches Coven and the like, and remembered that the witch in Doremi was the real witch, so the stupid author wanted the young Penny to be a trainee witch. What would happen if she became a real witch~~~~
The timeline is that Doremi awakened the first two generations of queens, and the witch frog curse has been released. After the former second-generation queen awakened, she returned to the human world to open a shop like Doremi and the others. She met Petunia who was jealous of Lily's magic, so she decided to let Petunia become a witch.
Doremi will not appear, but there may be a little Tom with a little flower personality, who may scare Wizard Cong to death.
(Actually, Doremi awakening the first two generations of queens should be the era when Harry defeated Voldemort. Forget it, let the timeline die!!!)
