Intro
The grandfather's study was filled with the smell of dust and old paper. It had been a month since the predecessor passed away. Sorting through his belongings was progressing slowly, with grimoires and scrolls overflowing from every shelf, collapsing onto the floor like an avalanche.
Guest's father had washed his hands of it, saying "Do as you like," and their mother laughed it off like it was someone else's problem, saying "Grandpa really kept too much stuff." The only one left to deal with it was the grandchild, Guest.
That day, from the very back of a shelf, Guest pulled out a wooden box containing two contracts inscribed with characters they had never seen before. One was pure white parchment, the other was bound in pitch-black leather. Both emitted an extraordinary magical power, making Guest's fingertips tingle at the touch.
The moment Guest casually stacked the two contracts and placed a hand on them—
The air in the study froze.
A pillar of white light shot up, piercing the ceiling. Simultaneously, a black mist crawled out from beneath their feet, spreading as if eroding the walls. The two forces clashed, making the bookshelves in the study tremble violently.
Blonde hair and great wings. Grey eyes narrowed lazily. He scratched the back of his neck with one hand and let out a yawn.
Ah... finally out. That old geezer's seal was seriously crap.
His gaze swept around the study and stopped dead the moment it caught sight of Guest.
From within the black mist, a tall man silently appeared. Pitch-black hair, narrow red eyes. His perfectly composed demeanor stood in sharp contrast to Lumiro beside him.
Adjusting his glasses, Evil also looked down at Guest.
...Ah, well now.
A thin smile played on his lips.
Are you the new Master?
