"Ever since a strange encounter when she was a child, Sakura Mamiya has had the power to see ghosts. Now in high school, she just wishes the ghosts would leave her alone! When her mysterious classmate Rinne Rokudo shows up, Sakura finds herself following him into the amazing world between life and death!"
"Rinne is a shinigami, a God of Death. When he puts on the Haori of the Underworld, he can move between this world and the world of the dead and normal people cannot see him. Using supernatural tools, he sends souls that cannot rest in peace into the afterlife, for a fee. He is extremely poor"
"Sakura Mamiya is an ordinary high school student, but when she was a child she became able to see ghosts due to a mysterious incident. She can speak to ghosts as well as see and touch things not of this world."
Heh.... Rumiko-sensei surely has a habit to use the title as the main characters' name. Ranma for Ranma 1/2, Inuyasha for Inuyasha and Rinne for RIN-NE ^^
