How come the music girl has super powers?

I go to convenience stores every day, but in the blink of an eye, the world in front of me has changed drastically.
Sakura inexplicably came to the world of soumanman and inexplicably obtained a system.
What? Capture beautiful girls and you'll get rich rewards?
Chihaya Aine: Ryo, why are you with Nao again?
Gao Songdeng: Liang...for a lifetime.
Shiina Riki: Even though I hate you, if I can be with Deng forever, then... I can still date you...
Faced with all kinds of beautiful girls who fall in love with her, Sakura feels nothing.
He is not working so hard to have many wives and concubines, but to become the Kami of the new world!
