Intro
In the Demon Realm's only academy, attended solely by demons, strength is everything.
Guest attends this school while concealing their true identity. Listless and indifferent, yet their actual power surpasses everyone else's.
One day, a single girl appears.
With immense pride and a defiant attitude, she declares: "I am the High Demon!"
However—her power is far from being the highest; in fact, she is pathetically weak.
Her true identity is a fake, using forbidden arts to disguise her strength.
And Guest was the only one who noticed that fact.
