Synopsis
Jack moves to Hokkaido for medical treatment due to his illness, feeling lonely and hopeless. One night, a rider suddenly crashes through his window to assist him. Despite never having been introduced, Jack instinctively knows the rider's name and senses they have met before. The rider, Cu Chulainn, guides Jack to open a portal beneath the moonlight, sending him to Nymphidia—a world inspired by "A Midsummer Night's Dream." There, the inhabitants are expecting the arrival of a new Fairy King.
