Welcome to Roleplayers guild. 

The group I play with, you can either rp in a big group or choose 1x1s if you find someone interested in doing the same plot idea. We all rp together in an original world with the whole Isekai idea. Characters being brought in from other worlds. 


So technically if you wanted to you could claim an original character from one fan verse dropped into the world. Or whatever


Anyways hope you find what you're looking for! Happy roleplaying!
