Hinata-sou's Resident Idol.
While growing up as a child, Naru was often sick and she was brought over to the Hinata Inn by her parents in the hopes that the different environment would be better for her health. It was here where Naru would meet Keitaro and Mutsumi, as the two were her playmates during her time at the inn. Mutsumi would talk Naru into taking part in a promise with Keitaro to meet one another again when both are able to enroll into Tokyo University and live happily together forever. As a reminder of the event, she was given a Liddo-kun stuffed doll by Mutsumi. With time though, Naru would forget about the promise she made with Keitaro until years later.
In middle school, Naru lacked any ambition for herself as such where she had poor grades and often day dreamed. However, she had gotten over the health issues that affected her in her younger days and she made friends with Mitsune. Naru often used Mitsune to turn down romantic confessions from boys at her school that were attracted to her because of her looks. Following a divorce between her parents, Naru moved into Hinata Inn as she was one of the first residents there when it was first converted into an all-girl's dormitory, residing in Room 304 of the inn.
It was here where Naru met up with Seta Noriyasu, who was appointed as her tutor to improve her grades. Her interactions with Seta led Naru to gain greater independence for herself, a greater motivation for studying and to gain a crush on her tutor. Naru would become intent on making her grades good enough to make it into Tokyo University. While excelling as a top student throughout high school from her grades, Naru would become socially distant from others and devotion to her studies led her eyesight to wear out, leading her to have to wear glasses to see things clearly.
She was the first inn resident that Keitaro encountered in a rather embarrassing predicament in Hinata Inn's hot springs that would kick start the hot and cold relationship that the two would have with one another throughout Love Hina.
Naru was one of the main female characters created for Ken Akamatsu's Love Hina manga series. She was originally going to be named Midori and given a more kind and nice personality. Her encounter with the male lead would have played out differently as she would have fallen in on him from the ceiling while naked and gotten amnesia. Much of her past would not be known, though the male lead would instantly fall in love with her and she would later take up a part-time waitress job. As Love Hina was further fleshed out, Naru's name and personality would be changed several times during series development until her current name and personality were adopted.
Naru has appeared in all anime adaptations of Love Hina which include the TV anime, Christmas special, Spring special and Love Hina Again OVA series. She was voiced by Yui Horie in Japanese and Dorothy Elias-Fahn in Englsh.
Naru stands at 163 centimeters (about '5'4"), with her three sizes being 83 cm for bust, 56 cm for waist and 86 cm for hips. She has long brown hair that extends to her waist and brown eyes. Due to being horribly near-sighted, Naru is often seen wearing glasses. While attending cram school for university examinations, Naru often wears thick glasses, sweaters and braids to deter attention from guys. In the anime, her normal attire consists of a yellow long-sleeved turtleneck shirt, a red short skirt, and black leggings. She is 17 years old at the start of the manga series and 18 at the start of the anime.
Naru is a responsible, kind and reliable young woman who is strongly devoted to her studies. She is also easily irritable and short-tempered as such where she is prone to quickly rushing into judging things with little regard for properly assessing the situation. Thanks to her tutelage under Seta, Naru was taught some martial arts by him and is able to comically launch her foes long distances with her punches and kicks.
While greatly disapproving of Keitaro's presence at Hinata Inn at first, Naru comes to admire his sincerity and persistence thus eventually getting used to his presence at the inn. However, she would be prone to pummeling him if she came across any misunderstanding that came up when Keitaro's clumsiness led him to a compromising predicament with any of the inn residents, including Naru herself. Naru's bedroom is on top of Keitaro's room as both are able to visit one another through a hole in the floor of Naru's room.
Keitaro would gain Naru as a tutor, though their bond did develop a rift for a time when he peeped into her personal diary and read an entry that had him suspect that she might the girl he made the promise with from years ago. Both winded up failing their entrance exams to enroll into Toudai and winded up unknowingly going together to southern Japan for a retreat. There, the two would run into Mutsumi and relationship developments with Naru and Keitaro are further complicated with Seta returning to the inn and the revelation that Mutsumi could be Keitaro's promised girl.
Following a misunderstanding that led Keitaro and the girls to Pararakelse Island, the two would learn that both passed their entrance exams to enroll into Tokyo University. However, Keitaro would wind up breaking his leg on the day of the entrance ceremony at Toudai and would wind up having to miss classes for the year. This resulted in him taking a trip with America for various excavation projects during the time he would have to miss. While Naru takes over as temporary owner of the inn, she finds herself at odds with Kanako who is trying to drive out the inn's residents to take over ownership of it.
Upon Keitaro's return, Naru's hostility with Kanako escalates as both try competing for his affection. While becoming increasingly attracted to Keitaro at this point, Naru is hesitant to confess her feelings due to fear of abandonment as she feared the inn residents would leave her much in the same way she felt abandoned by her parents and Seta. She is able to overcome this hesitance by confessing her feelings to him and the two starting up their relationship. The two would come to learn of the childhood promise they made with one another and would become married at the end of the series, with Naru taking up profession as a teacher after graduating from Toudai and becoming co-manager to Hinata Inn thanks to her marriage.
