Youkai Watch: Shadowside - Oni-ou no Fukkatsu

A 11-year-old boy named Keita Amano once owned a wristwatch capable of commanding Youkai, allowing him to befriend them and accomplish numerous feats. As he aged, he lost the ability to see Youkai, and the watch, deemed a threat to the balance between worlds, was discarded into an unknown void. Over time, the watch became a legend. Centuries later, a Youkai virus called Onimaro emerges, infecting people with harmful intent and transforming them into Kaodeka Oni, spreading chaos. As destruction looms, only those selected by a new Youkai Watch can confront this threat and prevent the downfall of both Youkai and humans.
