No-Life King

The Undying King (不死の王, Nō-Raifu Kingu; lit. Immortal King) is a mysterious and powerful figure who once ruled Grimgar over a century ago. After his supposed defeat, his curse of the Undead still lingers in Grimgar.

Souma's clan, the Day Breakers, have announced that there are indications in the lands of the Kingdom of Ishmael of the King's return.
