Rika is a high school student who has fallen in love with the school nurse, Kanewo-sensei. She was a sickly girl since childhood, and used to frequently visit the school infirmary because of this. Her friend describes her as an airhead, "rather dense" and that she has a "weakness for zombies".
Kanewo-sensei is the school nurse working in the infirmary. He is a zombie, but nevertheless he has maintained his ability to think, speak and move normally. Aside from the many bandages that cover some parts of his body, he looks like a normal, living person. He cares for Rika very much, and is familiar with her health condition.
Favorite color: pink Likes: food, her dog Francesca is a beautiful kind girl who is very strong. She eventually becomes a zombie after dying, losing her memory in the process because her brain ran away.
Hakka is the new President of the Ferrymen River Department in WFO. His personality slightly resembles that of Bekko's and Chika's father. He is sometimes serious, cool and mysterious, but at most other times he can be simply gay-like. He shows a rather sickening admiration and friendliness towards Bekko whom he calls "Bekko-chan," even feeling jealous of him because he has a "nicer ass." Motivated by Bekko's efforts in the Z-Loan office, he too sets up a loan company called A-Loan (Alive-Loan) and employs the trio Zen, Toko and Shuji. In actual fact, he is also the President of the ARRC (Akashic Record Reform Committee) and his real aim for creating A-Loan is to get rid of Z-Loan. He seems to know a lot more about the backgrounds and history of others such as Shiba and Michiru. In Volume 10 of the manga he reveals to Michiru that she is a Singularity and not a human.
