The Young Precious Metal and Stone Ninjas: Precious Metal Stone Humans vs. Humans, Vol. 1

A Cosmic War of Bloodlines and Crystals Begins... When a corrupted rain of gemstones falls upon Earth, transforming living beings into ravenous crystal zombies, only two ancient bloodlines hold the power to save—or doom—humanity. For 7,000 years, the Precious Metal Stone Ninjas of planet Verim have protected the balance between soil-born humans and their own crystalline kind. But when the rogue warlord Slotter unleashes his Black Diamond Curse, Sheriff Manner discovers his small town at the epicenter of an interplanetary conflict. Ritzy La Jitsu, a descendant of the legendary Jitsu family, holds the last spark of unconditional love—the only force that can reverse Slotter's corruption. Alongside her reluctant ally Sheer, whose body now half-belongs to the crystals, they must awaken the Gemstone Warriors within themselves before Slotter's empire of red and black diamond ninjas turns all of Earth into mindless mineral slaves.
