A shinigami that guides the dying to the afterlife.
He has a calming presence to others, whether human or any other animal. Being around him will soothe you. His touch kills humans, animals are exempt from it. His usual method of reaping is by holding his victim's hand. He's relatively neutral, on the side of lawful good.
He has a familiar, a white snake. It mostly stays under his robe.
Really tacky jewelry
Figs, juicy fruits
Children (they're sad to visit)
Old ladies think he's hot. He's gentlemanly to them.
He's forgotten how old he is and brushes it off as being a "grandpa".
