Unohana Mashiro was always capable of seeing things that weren't human, at least until she ends up being recruited by the Boundary Preservation Society which specializes in handling the boundary between life and death. She is also made the master of one of the noman "no man can normally see) named Bazu.
The manga was serialized in G's Comic Anothers from July 19, 2019 to August 27, 2020, for a total of 14 chapters.
The manga provides examples of:
- Artificial Limbs: When Bazu died, her spirit form consisted of only a head and torso (reflecting both her fixation with humans and her fatal dismemberment). The Society appears to have provided ghostly prosthetics for her missing limbs.
- Berserk Button: Mashiro does not like being called "short stuff." Which is why Bazu loves resorting to it.
- Bittersweet Ending: Mashiro is able to make peace with her older sister which allows her to finally pass on. However, Mashiro loses her ability to see nomans; Bazu leaves after accomplishing her desire to know humans more deeply; Mashiro resigns from her job after she lost her ability; and Chitose also leaves with Mashiro being unable to see her off. But the only positive is that Mashiro does reunite with Bazu who had been reincarnated into a human girl years later. And Chitose returns as a cat.
- Dark and Troubled Past: Bazu was once an injured crow who was nursed back to health by a kindly woman. When Bazu decided to go back to check up on her savior, another human grabbed her and cut off her wings and feet. Her encounters with humans and her traumatic death resulted in her becoming a noman.
- Defeat Means Friendship: When Bazu defeats Chitose, Mashiro takes pity on the ghost girl and petitions for her to join the Society.
- Don't You Dare Pity Me!: Bazu tends to get offended when Mashiro expresses concern for her.
- Extreme Doormat: Mashiro tends to let her classmates give her tasks due to her kindness. Bazu finds herself getting repulsed by this.
- Government Agency of Fiction: Nelly, Bazu, and Mashiro work for the Boundary Preservation Society, a branch of the government that deals with the threat posed by angry ghosts that can't or won't move on to the afterlife. In a stinger at the end of Chapter 4, Mashiro is shocked to learn that not only is she getting paid for her work as a public servant, but she's also getting paid a lot.
- I See Dead People: Mashiro's talent.
- Little Bit Beastly: Bazu is a crow spirit, but aside from a small feathery tail and pointed ears she looks just like a human. Nelly theorizes that Bazu's fixation on humans at the time of her death resulted in her current appearance.
- A Magic Contract Comes with a Kiss: When Bazu accidentally kisses Mashiro, she activates the contract Nelly had prepared and makes Mashiro her "master." That gives Mashiro the ability to issue orders Bazu must comply with, but in return, they gain supernaturally elevated healing rates (contingent upon physical proximity and/ or more kissing).Bazu: If we circulate spiritual power between Master and Servant... it'll make you heal faster.Mashiro: ...with a kiss?Bazu: That's how we started out, isn't it?
- Our Ghosts Are Different: Nomans are the souls of people or animals that had remained in the transient world after death. They are divided into two classes considering how dangerous they potentially were. Grade B noman are more dangerous and maintain their forms by consuming souls. Grade X noman (which is Bazu's ranking) do not recklessly steal souls and are incapable of entering Heaven. The Boundary Preservation Society handle them through special conditions hence how Mashiro became Bazu's master. However, there also exists Grade A Noman that are potentially more powerful.
- Reincarnation: Chapter 14 shows that Bazu was reborn as a human girl after she no longer had any lingering attachments. And Chitose became a cat.
- Tragic Bigot: While she knows that there are good humans, Bazu dislikes mankind because of her being tortured to death by one. She eventually sheds this later in the manga.
- Tsundere: Bazu is initially annoyed with having to be saddled with Mashiro, but she gradually grows to value her.
- Wham Episode: Chapter 11 reveals that Mashiro's sister actually remained in the human world as a Grade A Noman.
