The Daily Lives of Seven Villains from Another World

The writing is not good, please leave more comments and I will correct it when I have time. Seven men traveled from the spiritual world where they originally lived to a supernatural world in comics. There is a system that allows them to be villains here. Their original world has been clearly explained. After completing the task, they will be sent back, and each of the seven can choose an object from the Lord God to take back to the original world. Seven agreed. (Seven people can communicate in their heads, but they will pretend to use their mobile phones in front of people in the supernatural world. The seven people are originally friends, and there are twins among them! Although the seven people have different personalities, they will still accommodate the other six people... Right?)
