Message by day, spy by night, Hijo splits the heavens of Ynuma for the Raida nation. After becoming the protector of an Elf and a girl, he has only one mission: to survive the samurai who hunt them. On his Ten-no-Tori, Hijo travels through the heavens of Ynuma to deliver precious messages and artifacts. Marked by a painful past, he nourishes a tenacious hatred towards the Elves of Kitanaë. Yet, when his master sends him on mission to the heart of their city, he cannot refuse. Trapped, trapped, Hijo must protect an Elf and a child... without knowing why they are the key to his mission.
