Story
"What is real is defined by what is not.Who one is defined by who one isn't."
To move forward, one must accept these truths.
"Yes, in this prison—this cradle—
my dreams and reality became one."
Renowned adventurer Adol “the Red” Christin and his companion Dogi arrive at Balduq, a city annexed by the Romun Empire, only for Adol to be detained before setting foot inside. While imprisoned, he meets a mysterious woman named Aprilis who turns him into a Monstrum, a being with supernatural Gifts and the power to exorcise monsters. Now, Adol must ally with his fellow Monstrum to fend off the fearsome threats emerging from a shadowy dimension called the Grimwald Nox, as well as unravel the mysteries of the Monstrum curse, and the truth behind the unrest within Balduq.
