Dyna, a self-taught programmer, is naturally inquisitive and is fascinated by robotics, which she studies in her spare time. Eyuh, her "cat-like" AI robot, accompanied her wherever she went. She has persuaded herself that she leads a rather dull life, waking up to the same routine every day. Until that fateful evening... "It" happened on the night of the winter solstice, and it changed Dyna's life. It happened in the blink of an eye. She was standing on her apartment balcony with Eyuh, staring at the bright moon, when she noticed a baffling black smoke circling the moon, followed by the sensation of being gobbled up by a pool of air. The next thing she knew, she was in the middle of a dense and inexplicable forest. Her eyes widened in awe as she took a slow look around, nothing unusual - except that the forest is alive! Is she dreaming? Hallucinating perhaps? She let out a squeal when someone suddenly jumped in behind her, blazing orbs of fire casually dancing on his hand - ready to attack me. "Who are you? What are you doing in Sagaëi?", the strange man asked. Saga-Saga-Saga what? Where on earth is he talking about?
