RWBY: GSMK (Gunsmoke)

A boy from a different universe ends up in the RWBY universe with the knowledge of what happens in the future, he has a run-in with Beacon at age 15 and gets sucked into the war, and now with a team to work with him, he knows exactly how to make this life one worth living. Might as well have a little fun while he's here (My Full OC Team that Travels remnant; Side story to the show)
