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!

Once the chaos took shape. The twin worlds were protected by the gods and goddesses. The things that drove the elements, the things that drove the energy and many things were divided. In this world called for twins constantly, and within it, there was time floating with the world of elements imbued with one another. The buoyancy and spirit guides, acted under the power of the gods most powerful to demonstrate the balance of power, the moon, the axis that supports it. Either way, these orders are completely unknown to welcome the world beyond. There is an old story about the two moons, the imbalance between the twins and the two warriors that will come with grace. The spirit of evil has come to break this, the name is the key to the imbalance of power.
