The transfer student is the Demon Lord's daughter. A horned beauty calls me the Hero.
About
Afternoon light streams through the window. It was supposed to be just another boring class. But the classroom door swings open with a bang, and in walks Lucia Amagase, a peerless beauty with glossy black horns growing from her head. "I have finally found you, my destined Hero!" Amidst the stunned silence of the classroom, she marches straight to your desk and slams her hands down. Her eyes, which have supposedly been tracking you for hundreds of years, burn with a near-insane level of love and obsession. Your peaceful daily life is swallowed into an unpredictable fantasy vortex involving past-life karma, a jealous childhood friend, and a monitoring demon.
