Keitaro Urashima's Stepsister and Potential Love Interest
Kanako was adopted into the Urashima family. Rather than a platonic relationship, Kanako had romantic feelings for her adoptive brother Keitaro and the two made a promise together to run Hinata Inn together as husband and wife. While Keitaro was oblivious to the implications of this promise as a boy, Kanako took the promise as a literal one and hoped to one day run the inn with Keitaro.
Kanako was created as a major character for later volumes of Ken Akamatsu's Love Hina manga series. She was originally going to be Chinese, but the idea was quickly scrapped during development of her character. Kanako's character concept didn't change much otherwise during her development beyond being taller than expected. She would appear in the Love Hina Again OVA series, being voiced by Natsuko Kuwatani in Japanese and Melissa Fahn in English.
Kanako is 17 years old at the start of the series, having long black hair and brown eyes. She has a preference to dress in Gothic attire and is normally accompanied by her pet talking black cat, Kuro.
Kanako likes conducting herself professionally and to maintain a strict air to her that causes her to be distant with others. Wanting Keitaro all to herself, Kanako has a strong jealousy for the "promised girl" he met years earlier due to the attention that she took from Keitaro away from Kanako. She is a master of disguise able to impersonate the tenants of Hinata Inn and is a skilled martial artist as such to be a match for Motoko's sword fighting capabilities.
While Keitaro was away during his two-year long trip touring the world with Seta, Kanako would return to the Hinata Inn in an attempt to drive away the inn residents so she can reform it from an all-girl's dormitory to a proper inn. The changes resulted in the inn tenants having to work under Kanako to maintain their rent at the inn.
Upon Keitaro's return, Kanako would get in a hostile rivalry with Naru for Keitaro's attention when she came to learn Naru was the "promised girl". Taking advantage of the magic coming from the Forbidden Annex, Kanako would trick Keitaro into committing to its power so that their bond would not be tampered with. Despite its curse, Keitaro would persist in trying to commit to Naru and told Kanako that he only thought of her as a sister. Accepting of this, Kanako would allow Keitaro and Naru to become a couple and the curse cast from the Forbidden Annex would be broken.
