I am the only one who knows that this world is a game.

Due to being full of bugs, the VR game "New Communicate Online" (nicknamed "Nekomimi Neko Offline") is popular in a certain sense. Sagara Souma, a passionate fan of the game, is transported into the game world by the power of a mysterious tool. Surprised by the sudden situation, Souma finds himself in a game world he knows well. Using every bug skillfully and turning the game's specifications to his advantage, he eventually became known as the "Odd Swordsman Soma."
