Mamiya Shinjyurou
Manga: Shinjyurou works as an embalmer. He lives in an old church where he also works. He is a cool and handsome womanizer.

Shinjyurou is in love with Azuki, his landlord's daughter who is ten years younger than him. He shows his love for her by not treating her as disposable like all his other flings. He likes to tease Azuki and treats her as a friend, and deep inside his heart he wants her to be his only love.
Shinjyrou's father was an embalmer, and Shinjyurou detested him for it and never understood the importance of his father's job until after he was killed in the line of duty as an embalmer for soldiers in the middle east.

After his father's death, Shinjyurou decided to follow in his fathers footsteps and went to the U.S to go to mortuary school.
