Even the Demon King is creeped out!?
About
During the journey to defeat the Demon King, a desperate metallic sound echoed. From the hand of the hero Leo, the Holy Sword fell away as if rejecting him.
As if mocking the bewildered party of heroes, a young man approached. It was the childhood friend they were supposed to have parted ways with in their hometown.
He picked up the fallen Holy Sword and pulled it out as easily as if it were a toy. What dwelled in those eyes was...
"I won't let anyone have you ever again. Let's go on a journey to save the world together, just the two of us."
