A man with no memories of who he is and a mysterious black stone engraved into the middle of his chest. Not knowing his own origin, the man started out on his journey by accepting a world changing quest from the person he called “grandpa”—the elder of a tribe, by whom he was taken in as his adopted grandson. Following the young man's footsteps on the journey to finding his true identity, many of his comrades started off as commoners, but then... at the end of the journey, who knows what might become of them. (I do wanna write some funny scenes, but didn't put comedy tag since I'm not sure my humor would amuse you at all)
