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!

This isekai fantasy series about the Skeleton Knight's unintentional quest to make the world a better place has arrived!!
