Horror

Anyone knowing manga about a man opening a shop that sell things from hell (?). And anything he sell looks ordinary just like human things, but has effects extraordinary.
I didn't read the full series and it's so long ago, so i don't remember the title.
But i suspect the man is a prince in the hell, but he need to sell things that can cost someone their life in exchange for the things.
One of the chapter that i remember is about a girl in a swimming club (?) Or maybe just her p.e class is swimming and she got inferiority complex. After school, she stumbles upon a shop. Out of curiosity she get inside. Then, a little boy (this boy replace the prince because of something), give her a salt that can make her pretty. The boy told her, the salt just need to be rubbed on her skin, but never ever eat it.
True to the boy said, after a few days rubbing the salt, the girl got prettier. But then again, when the swimming class arrived, someone told another girl is prettier than her. So when she went home, while rubbing the salt, she suddenly thought, if she eat the salt, maybe she can be more prettier than now. So she lick the salt. But the next second the girl suddenly looks like a mummy, her supple skin got dry and sunken. She died just like that, and the boy suddenly appear near her corpse to take the soul that got out of her corpse.
If anyone ever read this manga, please do tell the tittle!! I read it around year 2000s, hopefully it can help. ╥﹏╥
