A female imperial guard of the Kuh�in family, Lin is the newest bodyguard of Murasaki, replacing her former guard, Kiba, due to female convenience. Armed with a pair of katana, her fighting skills are formidable, though not at the level of Yayoi Inuzuka. Although she disapproves of Shinkur�, nevertheless, she accepts him as Murasaki's companion, and frowns heavily on all the attention Shinkur� receives from other girls (even if he is unaware of it). Lin takes Murasaki's wishes literally, including attempting to get Shinkur� and Murasaki wedded to each other, despite not having permission from either party (or their families, for that matter). Under Murasaki's care, Lin is slowly learning about normal life, albeit with some difficulty. Lin is a completely different character in the anime TV series. She has no interest in the Kuh�in family matters and only works for them because she desires strong opponents to defeat.
She first introduced herself as Sirzechs' maid. She was the one who relayed the Gremory family's request to have Rias participate in a Rating game against Raiser. She is in truth Sirzechs's Queen, both in the Evil Pieces and as the Maou's wife.
The Student Council Accountant (treasurer). She is also a ninja. Yuka appears to be carefree most of the time. However, she is very cunning, mostly encouraging activities of the Maken-ki that involve some kind of other work that needs to be done. The most obvious of these actions is the "match" between Venus and Maken-ki, where the players use broomsticks and soap while playing in the pool. She is close friends with Furan and likes to tease her. Yuka is also the younger sister of Takeru's homeroom teacher Tomiko Amado. (Source: Wikipedia)
President of Student Council
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)
A fourteen year old girl with sleepy-looking eyes and a large scarf that Shinkur� "saves". She is actually a reputable hitman from the Akuu Company known as "Guillotine". Though she is just fourteen, she unintentionally has perverted reactions to events, such as assuming Shinkur� wanted a threesome in the back alley with her and Murasaki. As if pressing his hand against her chest wasn't proof enough that she was a girl, she even offered to show him below. She seems to be weak to the cold and heat. After encountering Shinkur� a couple more times, she develops a crush on him and steals a kiss from him. Now, she is trying her best to understand the concept of friends as she slowly makes the effort to make other friends within their circle. Even though she's an introvert, her personality dramatically changes whenever she wields any knife-type weapon in her hand. She appears to have supernatural strength, being able to carve pavement and metal railings into pieces with just one stroke using a butter knife. Much like Yūno H�zuki, her family, Kirishima, is also part of the thirteen Inner Families, descendants of assassins. Her male name indicates she is the direct descendant of the head family. Kirihiko appears in the OVAs of the anime adaptation.
