Haruka Urashima (ÆÖu ¤Ï¤ë¤«, Urashima Haruka?) is Keitaro Urashima's "aunt". In volume 1 of Love Hina she was originally called Keitaro's Haruka-oba-san ("Aunty Haruka"), as Ken Akamatsu needed someone in a position of authority to vouch for Keitaro. As noted by the series' anime screenwriter Sh¨ Aikawa (as Kurou Hazuki) as he was writing Love Hina: The Novel, Haruka also called Keitaro's grandmother Hinata-oba-san ("Grandmother Hinata"); as such, Hazuki and Akamatsu (who illustrated the novel) retconned the family tree to fit the anomaly.
Haruka Urashima is the only child of Hinata Urashima's eldest daughter, Yoko Urashima; her second daughter was Keitaro's mother (apparently the Urashima women keep their family name). Yoko worked under her mother at the Hinata Inn during her school years, especially at the inn's annex for the long-term residents. She was appreciated as bearing the closest likeness to Hinata, the beauty of Hinata City, as well becoming the first crush of at least one young man. Unfortunately, she died soon after giving birth to her husband's only child, Haruka, who also bears a strong likeness to both her mother and grandmother. Hinata then adopted her granddaughter. Therefore, Haruka is Keitaro's legal aunt in addition to being his actual cousin. It was as a teenager that, while working at the inn, she was first called "Aunty Haruka" by her baby cousin Keitaro ¨C the same time that Keitaro first met both Mutsumi and Naru. It is hinted in the novel that Keitaro first made the error as a result of mistaking Haruka with Yoko-oba-san, whose ghost haunts the annex. As a result, Haruka smacks Keitaro around every time he calls her "aunty" (as oba also translates as "middle-aged woman") but takes no further offense at the reference. In the manga, Haruka takes umbrage at being called "aunt" or "auntie" but generally takes no direct physical action to discourage it.
Haruka is the ry¨bo ("house-mother") of the Joshi Seny¨ Ry¨ Hinata-s¨ ("Women's Only Dormitory, Hinata House") and runs the Waf¨± Chab¨ Hinata ("Traditional Japanese Tea Room"). Haruka is constantly seen smoking a cigarette. Like Naru, she has a fiery temper (and great physical prowess to match), which she hides under a calm, detached exterior. Once a fellow student and love interest of Seta, she became fed up with his obsession for archeology, his tendency to get into trouble, and his apparent obliviousness to her feelings and left him.
Haruka's past with Seta is shrouded in mystery at the start of the manga, playing second fiddle to Naru's crush on Seta and Keitaro's interactions with the professor. It is much later in the series, after Seta comes back from the Parakalese ruins to propose to her (vol 9), that the rest of Hinata Inn finds out about it. After she rejects him, Naru and Keitaro eventually discover Seta and Haruka's shared history. During a trip to a hotel, Naru and Keitaro confront Haruka about her relationship. Sara, overhearing the conversation, pulls out pictures she pilfered from Haruka's room which proved that they were indeed a couple in the past.
Having traveled the world with Seta and Sara's mom, Haruka's skills in martial arts rival Seta's and can even surpass his when she is angry. She is also very skilled with firearms, which shows when she shoots Kaolla's missiles at Seta's head after being teased by him.
Haruka finally gets married at the end of volume 13 of the manga, within the Todai ruins in Kaolla Su's kingdom of Molmol. She is also instrumental in the sex comedy involving Keitaro and Naru late in volume 13 and early in volume 14, as she suggests that sex may need be involved in maintaining Keitaro and Naru's fledgling relationship. She stays in Molmol and helps Seta continue the excavation, but makes an appearance at the end of volume 14.
Haruka's seiy¨± (Megumi Hayashibara) sings the main intro song, "Sakura Saku" ("Cherry Blossoms Blooming"), and in episode 18, the other girls join in, West-End/Broadway musical style. Haruka's involvement in singing the intro theme was referred to by Seta before the group song starts as "You used to sing it a lot." The musical-style "Sakura Saku" track is included in the Love Hina soundtrack as "Sakura Saku (Lullaby Version)", with Y¨±ji Ueda (Keitaro) singing the first line instead of Haruka.
On the soundtrack, there are several other tracks that include all of the girls singing together. "Sakura Saku" is only one of these. Affectionately known as the Hinata Girls, the group has Megumi as a guest vocalist ¨C for example, during some of the Love Hina Live concerts. This grouping bears resemblance to Megumi's other anime group, DoCo.
