LatestIn ancient times, a great battle was waged between a master mage, Enno, and an evil demon goddess, Karuma. Enno didn't have the strength to defeat her alone and was forced to call upon Zenki, a powerful protector demon. After Karuma was defeated, Enno sealed Zenki away in a pillar located inside his temple. 1,200 years after this epic battle, Enno's descendant, Chiaki, unleashes her family's powers to summon Zenki.
Acting
Jurota Kosugi's unhinged vocal performance as Zenki.

Trivia, insights & behind the scenes
Zenki shares voice actors with iconic 90s roles: Kappei Yamaguchi also voiced Inuyasha, while Chisa Yokoyama was Sailor Uranus.
The series draws heavily from Shugendo mountain asceticism, with Enno Gyoja being a real historical figure—though the demon summoning is anime embellishment.
