The Seven Deadly Sins: Four Knights of the Apocalypse

As Percival turns sixteen, his grandfather tells him about the big world beyond their far-flung home — but the young man seems more interested in dinner.

On a journey to find his estranged father, Percival comes across a group of traveling performers who give him a lift to the nearest village.

Although Percival puts up a good fight, the black knight hasn't unleashed his full powers yet. Suddenly, a mysterious red fox appears.

Percival wakes up to find himself tied up and experimented on. His captor tells him that he's almost perfected the medicine he's been developing.

To return his grandfather to his original form, Nasiens will have to defeat another Holy Knight, and Percival is determined to help.

Percival and his friends come across a fierce young woman named Anne who, against her father's will, dreams of becoming a Holy Knight.
