Renge Houshakuji (宝積寺 れんげ, Hōshakuji Renge) is in Class 1-A with Hikaru Hitachiin, Kaoru Hitachiin and Haruhi Fujioka. Renge transfers into Ouran Academy as a means of meeting Kyoya Ootori who, due to his close resemblance to a dating sim game character with whom Renge is infatuated, she decides he is her real life fiancé. While her crush fades, Renge establishes herself as the Host Club's self-proclaimed manager and appears in the series on a regular basis.
Renge has mid-back length dark-blonde hair and dark-brown eyes. When she isn't cosplaying, she is usually seen in the Ouran girls' uniform and wearing a hair bow. A trait that Renge displays in both the anime and the manga is assuming the aspect of Medusa when angry, with her hair transforming into snakes. At such times, she can drive most of the other characters before her in a blind panic.
PersonalityRenge is intelligent and driven; she is also loud and outspoken. Her home is in Paris, France and her father, Reynard Houshakuji, does business with Yoshio Ootori. Upon seeing a photograph of the youngest Ootori son, Kyoya, she is smitten and insists that she must immediately leave for Japan to meet her future husband. Renge is a hardcore otaku, which results in her cosplaying frequently, examples of which may be seen in Ep 22 - Mori-senpai Has an Apprentice Candidate!, where she cosplays along with the Host Club as a samurai maiden and also in Ep 07 - Jungle Pool SOS!, when she cosplays as Quon Kisaragi from the anime Rahxephon. Renge has a rather strange and unique ability to appear from out of nowhere on a motorized platform that crackles with electricity as it rises while she laughs maniacally.
StoryRenge first meets the Host Club by maintaining the wild fantasy that she is Kyoya's fiancé despite never having met him in person. Her infatuation is based upon his striking resemblance to an anime dating game character named Miyabi Ichijo from Uki Doki Memorial, in which she seems to indulge 24/7. Still, her experience with such games and her obsession with anime and manga cause her to be more aware of character development and plot development techniques.
Though Kyoya expresses little interest in the girl, Renge wheedles her way into becoming the club's Lady Manager. As such, she attempts to make-over what she considers to be the Hosts' "bland" characters into something more enticing for their customers She does this to assist her "crush," Kyoya, who tells the other Hosts to tolerate her for business reasons. Tamaki Suoh allows this in hopes that Renge will become a female friend to Haruhi Fujioka and inspire her to act and dress in a more feminine manner. Much to his frantic dismay, Renge develops a crush on Haruhi, believing she's a boy. Renge is a flagrant fangirl/otaku and a huge fan of both moe and cosplay She self-promotes dojinshi in order to stimulate attendance at her "Kyoya's" Host Club. Despite her outrageous actions, she genuinely cares about the club's members and her misguided efforts are intended to help them. An example of this is seen is Ep 06 - The Grade School Host is the Naughty Type! wherein she helps elementary schoolboy brat, Shiro Takaoji, find his place among the Hosts.Amusingly enough, Renge proves to be an effective manager due to her ability to accurately predict what will win the greatest approval of customers due to her wide range of knowledge on various subjects, most of them connected to the concept of "moe." Kyoya has complimented her abilities in this regard several times. Renge also participates in activities which allow her talents to flourish outside of Host Club. In the anime, she is shown hosting a show for school children and she apparently is involved in producing the Moe Moe Ouran Journal (萌え萌え桜蘭日記, Moe Moe Ōran Nikki), a school magazine containing all things related to moe at Ouran Academy.
In the manga, Renge largely disappears from view after her initial appearance in Chapter 3, although she makes cameo appearances in subsequent chapters. Bisco Hatori has said that Renge was supposed to be more of a recurring character, but it never happened; most of her roles in the anime performed by Tamaki in the manga (e.g. the coaching of Shiro and Umehito Nekozawa). In the 2011 July Special, Renge is seen as a business student at Ouran University and is still quite the hopeless romantic.
