Gaea. A world currently unknown to ours has existed along us for millions of years, yet Earth and Gaea have not remained separate. This world is where the dragons, goblins, witches, faeries, and every other magical creature has come from and once dwelled on Earth, but the gateway has been closed a thousand years ago. Its inhabitants have faded into our legends and fairytales. Almost no one believes in them any more.
It is 2017 in Tokyo, Japan. You once thought you were ordinary, but strange abilities have began manifesting within yourself and others. No one understands what is happening, but you keep silent. You've heard of others with powers disappearing. You're wondering if and when you'll be next.
