Not So Real Reality

Reincarnated in the world of Remnant. With also a System? and Travelling to other worlds? Let's see what our protagonist will do, will he interfere with the PLOT or will he let the story continue as it should have? I wanna admit now this is my first ever book. At the start, I was just writing cause it seemed fun and left it but this time I will updating it on time. The first chapters are/ may be a mess I am sorry about that. I don't own RWBY or any Other Anime/ Manga / Light novel used except few OCs.
