The world changed the day that cracks appeared in the sky– suddenly monsters named『Demonic Beasts』appeared and began to rampage, attacking people.

Meanwhile, girls called『Magical Girls』began to appear to counter the demonic beasts. As they defeated the demonic beasts, gradually people’s lives gained a semblance of composure.

–but when there is light, there is also darkness.

In the corner of an alleyway, a boy who had been attacked by a demonic beast was dying. His voice begging for help did not reach anyone and his body refused to move.

「Boy. Do you want to be saved?」

Looking into the boy’s face, a black cat began to speak to him.

The boy nodded firmly to the devilishly sweet invitation, in response the black cat mocked him.

「Is that so—then I’ll【Haunt (Save)】you」

—on that day, a『Magical Girl』was born in a place that no-one knew.

『She』never laments, no matter what the future may bring.

“It’s not a lie, my family is really an ordinary family, I really don’t know any big people”

As a sophomore in high school, Chen Chu really didn’t feel that he was special, an ordinary family, an ordinary student.

Until a rich man in this city donated 10 million yuan to the school to install air conditioners for the whole school, build teaching buildings and sports fields.

In front of the teachers and students of the whole school, the rich man put his arms around his shoulders affectionately, and the leaders, teachers and students of the school were all surprised.

Chen Churen was dumbfounded: “Listen to my explanation, my family is really an ordinary family, and I really don’t know the richest people in this city!”

The city leaders came to the school for inspection, patted him on the shoulder kindly, asked him about his studies and how his campus life was, and invited him to visit him.

Looking at the strange eyes of all the school leaders, teachers and classmates who said “you are just an ordinary family”.

Chen Chu was numb: “I’m not lying, my family is really an ordinary family, how can I know the city leaders!”
