Plot

A gamer ends up in the world he was playing, but also with the skeletal appearance he was using. Now he must make his way in the new world conscious of his frightening appearance.

When Arc wakes up, he discovers that he has been transported to another world in the body of the character he was playing in an MMO. Looking like a suit of armor on the outside and a skeleton on the inside, he is the Skeleton Knight. If his identity is discovered, he could be mistaken for a monster and become a target. Arc decides to spend his time as a mercenary so as not to attract attention to himself. However, he's not the kind of man who can stand idly by when he witnesses evil acts take place right before his eyes.—Crunchyroll

After falling asleep while playing an online game, a man wakes up and finds himself transported to that game's world as his in-game character, Arc. He wastes no time adjusting to his new environment, but soon realizes that he is using the skeleton avatar he chose when creating his character, which forces him to hide his visage to avoid unwanted attention. Arc goes to the nearby castle town of Luvierte, hoping to become an adventurer and take on quests to earn money. With his overpowered abilities, Arc embarks on a fantastical journey-exploring diverse territories, looting various monsters, and helping people get out of sticky situations. However, his seemingly innocuous actions may soon involve him in a brewing large-scale conflict that will forever alter the fate of the realm.—MAL Rewrite
