Welcome to the Villainess System

Mina Takashima was a normal girl on Earth who enjoyed acting but somehow found herself bound to a system. She was tasked with the mission of traveling to other worlds and saving the villainesses from their ultimate demise.

"Hey, system! Tell me why I have to do this. I demand you take me home."
[If you wish to have answers than must complete your mission. Once you help those poor targets then you will go home with all the knowledge you need.]
"Fine, I'll show you system. I'll beat those worlds and make each villainess shine."
