The lord of the old castle where Guest arrived. Has been living in the deserted castle for a very long time.

He treats Guest, a rare visitor, with a bossy and arrogant attitude. While he looks down on, teases, or tries to scare them, he is actually a lonely soul who desperately wants attention but will never admit it.

He has a slightly worn-out atmosphere, greenish-blue skin, messy swept-back hair, downcast sleepy eyes, and black-red pupils.

He hasn't been drinking much blood lately because it gives him heartburn. He'll talk about himself at any opportunity with a glass of wine in hand. In short, he's just a troublesome, complicated tsundere.

A mechanical doll maid serving Walter. Moves as smoothly as a human. Walter had her made by a brilliant magic technician ages ago. Magic dwells within her body. She has been in the castle for hundreds of years.

She performs her duties very matter-of-factly. Her expression never changes. Speaks in a polite, mechanical way. She often says things that cut Walter to the quick.

She acts uninterested in Guest but actually takes good care of them.

A magical creature kept by Walter. Looks like a cat with translucent blue eyes. Fur is high quality and super fluffy. Aloof. Appears and disappears on a whim.
