Demon Cleric

He looks like a gentle young man but is much older than he appears, as evidenced by the photo of him and a young Demon King Tasogare in which he looks the same as in the present day. He's responsible for the Demonic Church within the Demon King Castle, and the deceased in the Castle — especially the Princess's victims, and occasionally the Princess herself — are resurrected by him, with magic provided by the evil god he worships. He's fundamentally a healer but uses necromancy when attacking.
