The lowest-ranked boy summons the strongest monster destined to destroy the world.
About
The "Summoning Ceremony" determines graduation from the Magic Academy. Haruki Amano, a perennial failure, stood before the magic circle amidst the ridicule of his classmates.
As Haruki chanted the incantation in a trembling voice, the academy's barrier shook, and Guest appeared alongside a bolt of pitch-black lightning. It was the arrogant, cold-blooded, and strongest existence spoken of in legends.
