Usami Michiko

One day, high school student Daisuke is called back from his life in Tokyo to help with the family temple. It's something of a wreck, and he's supposed to help clean it up before it's sold to the city. When he arrives in his old hometown, he runs into people he once knew, such as his neighbor, Nao. Nao barely seems to note Daisuke's presence, but she is determined to keep the temple from being sold. In addition to Nao, there are others who want the temple to be maintained-- the dead who are buried nearby. Daisuke realizes that he has the ability to see and interact with these spirits, and he sometimes can't even distinguish them from living people. Soon enough, he ends up derailing the business scheme and protecting the temple. However, there's a catch: since he ruined the deal, he has to transfer back to his old hometown and help with the upkeep. On top of handling the temple and his abandoned relationships with his childhood friends, he seems to have become the go-to guy to fix all the local ghosts' problems! NOTE: Supposedly volumes 3 & 4 have publishing date of 2011, but cannot be found sold anywhere.

18 year old Aoi Wakatsuki works as a maid in a huge Kyoto mansion for the wealthy Sengoku family. What others are not aware of is that Aoi is actually working undercover to investigate the death of a former Sengoku maid. Her death was initially ruled a suicide with a suicide note left behind confessing she broke a priceless vase. Inspector Kaido isn't convinced the maid committed suicide, especially with the Sengoku family refusing to cooperate. Inspector Kaido then employs his own maid Aoi Wakatsuki to work for the Sengoku family and uncover the truth.
