Monster and the Beast
Complete | Renji Range | 2000 released
Absolutely adorable couple of a demon who was feared by everyone but a middle-aged eccentric man who was the result of a war experiment and therefore his humanity is debatable. Because it seems they are both immortal to some extent it seems their happiness will continue for a long time as they travel together to see all the wonders the world has to offer
