[Japanese light novel + magical girl + daily school life + battle]
The mother who left home unexpectedly told Duanmu that she had a small company in Neon. She sent Duanmu to Neon so that Duanmu could adapt to life and study there, and then directly took over the company.
In her apartment, Duanmu signed a contract with a creature that looked like Kyubey. The creature that looked like Kyubey told Duanmu that becoming a magical girl could gain eternal life and bring hope and miracles to people, and it didn't cost anything.
Duanmu was very doubtful about this. After all, how could bringing hope and miracles be without cost?
