This series is really short, there are only four books in the whole series! But it's worth reading!!
It starts off when a man named Shuichiro resuced a small angel from a crow. The angel thanked and said she would grant him a wish. But Shuichiro didn't have anything to wish for, but sense Kohaku (the angel) couldn't only thank him for saving her life, she decided to help him by cleaning his house and other misc. jobs. Once he finally excepted, the angel was then living with him.
But, if there are angels, then there must be devils, which could cause a problem....
