Saeko's surname is unknown. She belonged to the Play Faction during the Survival Game, along with one of her best friends Mihara Kozue. Her first voice debut was in episode 4 for the 2nd Term. She shows herself to be eloquent and suave when it comes to dealing with guys and is a master of seduction able to quell even the likes of Kouriyama. She was Cafe Rumble's #1 girl. Saeko has a weird sense of humor; the script she submitted for class 2-C's play was among the more colorful. Saeko also features herself on the front cover of volume 11 of the Manga along side Tougou Masakazu. Mihara Kozue: Kozue and Saeko are often shown chatting in the hallway
The girl who sits next to Harima who you see during the scenes where Harima attempts to tell Tenma to put her name on her test. In the Survival Game she was on the Cafe Faction. Rinko appears as the narrator in the Class Play during the Cultural Festival, cosplaying as Saber from Fate/Stay Night. This character has not been formally introduced in the series yet. She has been nicknamed "Rinko" by multiple Japanese fans on School Rumble @ 2chan which means "Next Girl," since she sits next to Harima, but her name has never been mentioned in the anime or manga itself. Despite not having a name, she has received a speaking role in episode 2 of School Rumble Season 2, where she infamously refers to the relatively unimportant and insignificant character, Ishiyama Hiroaki, as the other guy completing the insult that Hanai Haruki started. Strangely enough, she is officially listed in the cast credits as "Rinko." It is still unclear whether the producers took this from the fans or if indeed the producers coincidentally intended her to be "Rinko." "Rinko" was part of the 3rd Character Popularity Poll as "2-C Girl #1." She received 95 votes and placed 25th out of 66.
Miiru is a new freshman at the college Taka, Keisuke, and Tetsuya attend. She decides to join Keisuke's Ancient Chinese Mythology Club, where she sees and reads some of the "Shi Jin Ten Chi Sho".

A dragon of heaven, Sorata is an upbeat, irreverent teenager possessing considerable occult abilities, raised by the Shingon Buddhist monks of K�yasan after being taken away from his mother at a young age. A gourmand, he was frequently in trouble at the shrine for stealing food between meals (insisting that he couldn't wait until dinner), and is also a competent cook. It was prophesied that he would protect Kamui with his life, but that he would die for a woman; the first time he meets Arashi, he decides she will be the one. An incessantly friendly young man, he wears down the resistance of both Kamui and Arashi and worms his way into their affections, despite their initial coldness and his own unrefined Kansai dialect. In addition to generating powerful electrical discharges, he is also capable of calling upon a goh�d�ji, a magical being similar to a shikigami manifesting as a massive, hideous ghostly creature. It is psychically linked to Sorata, allowing him to spy on others and act at a distance from himself, but he suffers any damage inflicted upon it. In Tsubasa Reservoir Chronicle In the Republic of Hanshin, he's a cheerful history teacher married to Arashi and is host to Syaoran's group when they first arrive. In the apocalyptic world Tokyo, he's one of the seven fighters of the Tower faction.
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)
