Anime Like Youkai Watch: Shadowside - Oni-ou no Fukkatsu
SYNOPSIS
Three decades have passed since a boy named Keita wielded the legendary Youkai Watch, and the world has forgotten the bridge between humans and supernatural creatures. The watch itself vanished into the void, deemed too dangerous to let exist. But when a sinister plague emerges, everything changes. A mystical virus called Onimaro targets those harboring dark intentions, warping them into twisted demon-like beings called Kaodeka Oni. The infection spreads unchecked, turning ordinary people into monsters driven by their worst impulses. As society crumbles under this invisible threat, a new generation discovers the old legends might be more than folklore. Youkai have always existed in the shadows, and now humanity needs them more than ever. The question becomes whether the sealed watch can be restored and whether anyone remains capable of bridging two worlds that have spent decades completely separated. What unfolds is a supernatural thriller about rediscovering forgotten connections in humanity's darkest hour, where friendship with the unknown becomes humanity's only salvation.
