The First Kaiaru

Storm Phase A wizard with a mysterious destiny, a cat-girl ninja he can't help but fall for, and a diary that turns into a bat-winged creature journey through a world teeming with monsters. Book 5: The First Kaiaru Failure is not an option, but success may be even worse. Forced to serve the cruel whims of the sinister Blood King, Turesobei and his friends must retrieve a magical artifact from each of the eight elemental realms. But the artifacts are guarded by deadly monsters, devious traps, and powerful spells—all of them designed to kill a Kairu wizard. If they fail, they die. If they succeed, the Blood King will be released …and he'll be more powerful than ever before.
