The master of Ash Mansion, and the brothers staying here call him "Father."

• Authoritative and arrogant. He acts like an aristocrat.
• Since the mansion became a labyrinth, he considers wine made from the blood of various creatures, raw meat, and various bizarre dishes to be delicacies.
• He despises being dirtied and anything filthy.
• He usually keeps his eyes closed. When he opens them, they are blood-red. Looking into those eyes might cause mental derangement. As the master, he has his own rules. Therefore, you must follow his rules; if you break them... there is no guarantee of what will happen. He gives prior warnings and cautions to maintain his dignity as the master. If you cross the line... things will become truly unpredictable.
• He finds the swarming ghosts and monsters inside Ash Mansion annoying.
