If you took out all the dead people and creepy bits from Kurosagi Corpse Delivery Service, you'd probably end up with something like Moyasimon. Both are comedic slice-of-lifes about university students (or, In Kurosagi's case, young adults that just graduated) that have rather... odd talents/careers.
And with Moyasimon's frequent tangents on microbial biology and Kurosagi's extensive and interesting endnotes, you might even learn a thing or two.
Another episodic manga about money-obsessed characters who have the power to talk to, and bring the dead back to life. Both are pretty gory (though Reiko is far more so), and have lots of black comedy.
All murdered souls arrive in limbo at the Gate of Grudges, where the Gatekeeper, Izuko, presents them with a choice: they may pass through the Gate into Heaven; they may cling to life on Earth and remain a ghost there forever; or, they may haunt and kill one person in exchange for eternal damnation. As each spirit passes before the Izuko she is bound to explain these options and impartially accept their decision; what will each choose? Peace, or spending an eternity in Hell?
Skyhigh and Kurosagi Corpse Delivery Service are a series of separate (but related) stories about the last decision a dead person is given (where to go), and the person/people who assist them. Kurosagi is more lighthearted.
When a person dies, their soul does not enter the land of the dead alone; a Companion must lead them to the gate that leads to the afterlife. Existing in a space between life and death, Aya and other such Companions will help carry those who have passed on to their final destinations, even if they refuse to accept their fates.
Kurosagi and Companion star protagonists who must shuttle the souls of the dead in some way to their peace. Kurosagi is darker and has more humor, but fans of one will definitely appreciate the other.
At first glance, Kimihiro Watanuki appears to be a normal high school student; but little do people know that not only is Watanuki able to see spirits, but he's also a magnet for them! One day, after being chased by one such spirit, Watanuki happens upon a strange building. There he meets a mysterious witch named Yuuko, who claims she can get rid of his ability to see spirits - for a price: Watanuki must work as her housekeeper until he has paid off the cost of granting his wish. Now Watanuki's eyes are being opened to an entirely new side of the world as he assists Yuuko in her work, all while balancing the housework, his schoolwork, and most importantly, ensuring that Yuuko is never out of sake!
Both of these series are steeped in Japanese culture (Kurosagi more modern while xxxHolic more traditional), both concern strongly with the supernatural but take place in a realistic setting, and both are about the fulfillment of wishes.
The Kurosagi Corpse Delivery Service help the dead achieve their last desire, hopefully for a cash payment. In xxxHolic, customers come to the shop of a witch to have their wishes granted at the right cost and usually end up learning hard lessons.
xxxHolic readers, be warned that Kurosagi can be pretty graphic and is definetely meant for an older audience. Kurosagi readers, be warned that xxxHolic is by CLAMP and thus caters (a bit) to yaoi fangirls.
