Gamer: GateKeeper

Many people have read or watched isekai anime or manga. Heck, some even read fanfictions about it, even self-insert. We all dreamed about cruising across the multiverse as an OP MC. Too bad the multiverse wants me dead. At least I got the Gamer... Oh C'MON! what did I even do to deserve this?

A/N: Formerly Gamer Oh c'mon

To anyone first time reading this the story ends in Battle of Demons the continuation is in another book; Gamer: Fate rewritten.
