Only I Know That This World is a Game

One day, Souma Sagara, a college student and hardcore gamer who puts his hobby above everything else, finds himself sucked into his current game of choice—New Communicate Online, aka the Catfolk Realm. But what seems like a dream come true could easily turn into an unmitigated tragedy, as the game is infamous for being a buggy mess coded by malicious developers! Robbed of his ability to save, reload, or access any of the game’s features, Souma must take on the Catfolk Realm with nothing but his wits and in-depth knowledge of how the game works, bugs and all. Follow along as he interacts with various NPCs, breaks quests, and glitches his way to success in a world where a single game over means certain death!
