Life in the spirit forest is pleasant for Rio and Latifa—but alas, their time together there isn’t meant to last. With a promise that he’ll eventually return, Rio departs for his parents’ hometown in the Yagumo region. A small village holding the secrets of his birth awaits him…

Rio’s journey to Yagumo takes him and Latifa deeper into the forest—and its denizens aren’t happy to see them! Can Latifa convince the Spirit Folk’s warriors of Rio’s innocence and forge a new bond? And what of Haruto’s spirit still slumbering within Rio?

Rio is a run-of-the-mill seven-year-old orphan from the slums who serves as a lookout for a local gang. Yet when he falls into a fever, memories of a past life surface. After the gang shoos him away from their hideout to celebrate their latest haul, Rio wanders into town, still coming to terms with his new memories. There he crosses paths with a group of nobles looking for a missing girl. When Rio returns to the hideout, he finds the gang slaughtered-and the perp's still around! What's worse, the gang's haul was actually the girl the nobles were looking for. Rio has to combine the martial arts from his memories with the magic power of this world to fight his way out of trouble and save the lives of both the girl and himself!

Rio sets off for his hometown via parts unknown...so why does everything look so familiar?

Moreover, who is this fox girl trying to kill Rio?!

After departing his parents’ hometown in the Yagumo region, Rio reunites with Latifa in the spirit folk village. She pours her heart out to him, and he responds with a special promise. Rio’s travels then take him to the city of Amande, where he witnesses six pillars of light rise up toward the sky. A voice in his head beseeches his help, leading him to an unexpected discovery…
