Between our conscious, waking world and the subconscious state of slumber, there is a thinly veiled plane of lucid dreaming. While the conscious state belongs to individuals, the hidden plane of dreams is one shared by all human minds, past, present, and future. Yet only a few have ever possessed the power to enter this secret realm at will - where a war is being waged to control the waking world. For our earthly wishes and desires are not our own, but under the manipulation of these unseen masters of dreams. The heroine of Gate 7 is Hana, a high-school girl hailing from Kyoto, the daughter of a temple caretaker. Her peaceful ways give her the self-control to act in the hidden realm. But Hana can only reach it through the strange beast that acts as her totem in the world of dreams - and her companion on a journey to confront the puppeteers of our reality!
