Brother, Are You Also a Magical Girl?

"Li Yan, how do you deal with your relationship with your adopted sister?" "It's very simple. We study together, live together, and become magical girls together. We naturally become familiar with each other." "What does it mean to be a magical girl?" "Literally, a hero who goes out at night, goes through life and death, and solves disasters caused by virtual beasts." "Okay. Now that you've even become a magical girl, you and Chen Xi have become close brothers and sisters." "Indeed."
