At the Kameishi Excavation Branch Office, where Moe Nagakura has just started her new job, works a genius young man named Muryo Saibara (21). He is a young archeologist whose right hand bears a burn scar resembling a laughing demon's face—earning him the nickname 'The Demon's Hand.' With that hand, he consistently unearths historical artifacts of National Treasure caliber. At the request of a university excavation team, Muryo heads to the Kamihada Ancient Burial Mound in Nara accompanied by Moe. There, Muryo discovers the 'Sea Jade of Hourai.' However, dark shadows begin to close in on them, all vying for the mysterious green jade orb! This popular series by Mizuna Kuwabara is finally being adapted into a comic by its official illustrator, Munk Mutsuki!
