Cong Yu, male, 17 years old, is a student.

His hidden identity is a cadre of the Monster Group. He is currently on leave without pay to go to school for further studies.

He lives in a villa area in the northeast of Fengdu, alone, and his house is quite big.

He thought that this kind of life would continue until he graduated from high school and college.

But the sudden intrusion of the magical girl changed his life!

"I am Cong Yu's dog! Woof woof woof!"

"Cong Yu, you don't want your true identity to be discovered, do you?"

"I am the magical girl you corrupted with your own hands, you have to take responsibility!"

Amid the noise of many magical girls (doubtful)...

Cong Yu, who didn't know what expression to show, could only smile.
