Princess Shiori has promised that she would return the Dragon’s pearl to its rightful owner, which leads her on a dangerous journey. On her quest, she descends into the kingdom of Dragons, far under the ocean. Meanwhile, demons still threaten the kingdom of Kiata, and Shiori is the only one who can defeat them. As she navigates between worlds of Dragons, Humans and Demons, Shiori must also face the power of the corrupted Dragon’s Pearl itself. Can she return the pearl, which at times jumps to her aid, only to betray her the next minute? And can she defeat the demons that threaten her home?
