ShadowCrest

At Arthurwood Academy, a mysterious student named Itsuki hides immense power behind a calm, silent exterior. Assigned to the weakest rank, he secretly eliminates demons alone—absorbing their aura and growing stronger. Girls are drawn to him, but he stays distant. When the Demon Lord appears in his dream, revealing Itsuki's hidden destiny, a storm begins to brew. Unknown to all—the king has already awakened.
