In an Anime world! With a System?

One Night I, Kayn Thomas, fell asleep and was transported to another world. Although this is weird enough, I have a System?!?! -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ I Don't Own Some of the characters in this story, mainly I own the MC, and his family as well as some Side Characters. Feel free to leave advice and suggestions for what to happen in the story! *I do not own the cover picture btw, if anyone wants me to take it down just tell me
