Utsuru Sanada is a professional photographer at the age of 17, he can guess the exact 3 sizes of any girl, he can memorize anything he sees, and he can counterattack karate moves (Most guys would want these abilities). Why? Because he has superb photographic memory called “Shutter Eye” (Shutter as in the shutter of a camera). He meets Niko Kurihara, the female protagonist, who dislikes men, is a master of martial arts, and is of course beautiful. As the story progresses, Niko at first thought he is an impure guy, but soon realizes he is unpredictable and not what he seems in her eyes. . .
Yuzuha is Oboro's little sister and a friend to Aruruu and Camyu. She has been very sick with an unknown illness all her life, and is blind. Although bedridden most of the time, her senses of smell and hearing have been whetted by her lack of sight, and enabling her to recognize a person by their scent or even the manner of their footsteps. Yuzuha possesses a gentle persona, which she made especially apparent when dealing with her older brother, and in the fact that she refuses to let an animal die in the hope of obtaining her disease's cure. Sadly in the ending of the last episode (set unknown time after the events of the main series, but with the characters seemingly similar in age and appearance) she is presumed to have passed away. You see her brother Oboro visiting her grave and bringing the bell she likes. In the game, she's able to bear a healthy child by virtue of Hakuowlo's divine blood which can control her illness for some time. Oboro cares for the child in place of his late sister and leaves on a journey to show it the world.

Hinako Ninomiya was employed by Principal Kuno to help deal with all the "delinquent" students at Furinkan High. Initially she appears to an elementary school aged child who is rather giddy and excitable. In actuality her tale is much more complex. When Hinako was very young, she was quite sick and was hospitalized. While there she was discovered by Happosai and learned a chi-draining technique from him (he taught her this so that she would stop the nurses from chasing him after he stole their underwear). When Hinako uses this technique she grows into an older, twenty-something woman (her proper age). But the rest of her time is spent as a young, energetic child. Her personality changes to reflect her different ages. Hinako is the homeroom and English teacher at Furinkan for the 10th grade. She also has quite a crush on Soun Tendo because he was nice to her when she was in her child form. Hinako looks upon it as her mission to help Ranma improve his behavior, whereas Ranma would much rather spend his time doing just enough to scrape by scholastically speaking. (Source: Rumic World)
