Awakening of the Guardian Spirit: the Paper-Pricked Man Comes to the Door

This is a world of guardian spirits. Everyone awakens his or her guardian spirit at the age of eighteen. The guardian spirits come in different forms. Some are humanoid guardian spirits, some are monster guardian spirits, some are weapon guardian spirits, and some are weird guardian spirits... Wait a minute, I'm the awakened guardian spirit. What's going on if you, a paper-cut person, come to me?
