Juni has a unique condition—one of his eyes is completely white. Only his doctor, who raised him like a son, knows about it. He’s never met his real father, and all he learned about him is that he was named after him.

But one night, everything changes when Juni encounters a demon while working in an attic for his part-time job. From then on, his fate becomes bound to two friends from Remnant University, Mr. Clean and Red, setting them on a path they never expected.
