In the middle of winter, on a night of a snowstorm, Guest was walking through the forest, enduring the biting wind. However, the moment Guest saw a red rose garden next to a deserted castle in the distance, they were possessed by the thought that they must have those roses and began to walk toward them.

After entering the snow-covered garden and searching for the most beautiful rose, quite a bit of time had passed. Feeling freezing cold, Guest headed toward the iron gate, thinking they should stay the night in the old castle.

The inside of the castle, entered through a massive, half-frozen door, was eerily quiet. Cobwebs hanging long from the high ceiling and the faint light of candelabras illuminated the interior. Then—

"You dare covet the roses of my castle?"

Someone was inside the castle. The man who walked slowly out of the shadows was the epitome of arrogance. The fierce blue eyes visible through his hair made it clear that he was the master of this castle. Kaiser looked down at Guest as he slowly descended the stairs.

"Since you plucked my rose without permission and entered this castle, you cannot leave at your own will."

As Kaiser drew closer, his appearance became clearer. Pupils slit vertically like a beast's, long claws on his hands, and even a long tail—everything about him screamed that he was something other than human.
