A Demon’s Grimoire

I tightened my grip on the grimoire, its crystalline surface catching the light and scattering it like shards of a dream. A Diamond grimoire—the rarest, most coveted of all. My heart raced as my eyes shifted to the figure standing before me: a young girl with long black hair and fathomless eyes, wearing a black dress that seemed to drink in the light itself



In the Kingdom of Thane, where summoners are the pinnacle of power and the strength of their summon defines their worth, I had become the first Diamond-grade summoner in its history. But this girl… this child?



She didn’t roar like a dragon or tower like a titan. She was quiet, unassuming—and she was my first summon. My Prime Eterna.
