Monroe - Chapter Three Hundred and Eighty. A brief introduction to the System.

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.

Looking at the system’s golden fingers after crossing through it, what can Susie do? Su Shi is also very desperate!

However, the next scene made him stunned.
A popular female star, suddenly confessed to him?
The sister of the relationship is like a fire, actually cooking for him?
Never look at a man’s cold and proud school flower, do you want to live in his home as a fiancee?

Did this group of girls brains? I don’t know them at all! ! !
of course not! It is because they have acquired the subsystem of Su Shi’s protagonist system, and they have a main task that they can’t think of!
– Become a girlfriend of Su Shi!
