Hobo Heart is a Gemberling, a humanoid being used to serve their master. Hobo became a free man after finding a loophole in the task he was required to do. Hobo is feared and disliked, despite him being a soft-spoken, well-mannered man. He resides in a dense forest mainly, but he is also seen around the outskirts of his town or in botanical gardens. He finds peace in the vacant and quiet areas.
