In an ordinary world far from fantasy and magic, 16-year-old Ryu lived a life filled with routine and friends in a boring city where events lacked excitement. He wished for greater things, wanting to experience adventures that would make his heart race. One day, after a long school day, he decided to take a shortcut on his bike through a steep alley. As he rushed out of the alley, a speeding car appeared before him, coming from the opposite direction. In a matter of moments, pain surged through his chest, leaving him in a state of unconsciousness while he took his last breaths, reflecting on a life he had yet to complete and the dreams that would remain trapped in his heart.
But death was not the end of his story. Ryu awakened in a new world filled with darkness and wonders, where he was reborn as Mizaki. He possessed memories of his past life and an indomitable determination to return to his world. In this new journey, Mizaki begins to explore his true power and must learn to balance between shadows and light.
