The S-Class Butler

Butler Kim is the raid leader of the virtual reality game "Metaria" and the guardian of two cats in real life. One day, a mysterious boss monster appears in the game and forces him to change his job to "Butler." Forced to serve the monster, Butler Kim discovers an unbelievable truth.

"Oh my... a cat has logged into the game?!"

His pet cat, Pichiu, has entered the game. But the shock doesn't end there. The "master" who chose Butler Kim as his butler and has been communicating with him is none other than Kalinas, the embodiment of darkness. He, who should be the center of this world, is trapped in the body of Pichiu, unable to do anything! Now, the butler's duty becomes clear: Butler Kim must carry out the dark mission in his stead. But does the incarnation's mission really matter to Butler Kim? Is he simply happy that he can embark on a fantasy adventure with Pichiu?
