Oriko Seki, whose parents were killed in a vehicle accident, wound up living in her grandmother's Onsen Ryokan, "Haru no Ya." With the ghost "Uribou" cohabiting with her and all the other obstacles, she became a young female innkeeper. She disliked the exercise at first, but as her admiration for her position grew, she began to train with greater intensity. Thus begins Oriko's development as a young warrior.
