Kaolla Su
Kaolla Su
カオラ・スゥ, Kaora Sū is a 14-year old foreign transfer student. She is also a boarder at the Hinata Inn, in room 301.
Su is a princess of Molmol, a fictional island nation located near the International Date Line. The dot on her forehead seems to have something to do with the 3-eyed symbol of Molmol. She is often barefoot and dressed in nothing else except her heavily altered school uniform in almost every anime episode and manga chapter, or some otherwise scant costume. To top her personality, she is above all extremely hyperactive, usually hugging (or, in Keitaro's case, kicking) someone, trying to eat something, especially bananas and/or Tama-chan, or inventing some potentially dangerous new device. She also has a tendency to snuggle against a person while she is sleeping and usually crushes them while doing it.
Molmol is a kingdom where the moon sometimes appears red. It also uses a western naming order, although the Hinata Inn residents never seem to pick this up until later: Su is actually Kaolla Su's family name.
Su likes all the other residents in the Hinata Apartments and gets along well with them, though they have difficulty keeping up with her hyperactive tendencies; only the athletic Motoko seems to be able to tolerate and keep up with her. Her like for Keitaro stems from the fact that he reminds her of the person she refers to as her older brother (actually her cousin, whom she grew up with). However, it can be inferred that she eventually comes to care about Keitaro as much as and perhaps even more than her older brother.
While she has stated that she likes everyone in the Hinata apartments (including Sarah, who was sent there for a short period of time), it is apparent that Kaolla shares a much deeper relationship with Sarah and Motoko as compared to the other residents. Her ambition is to return to her homeland to start a computing school and transform her country into a technological power that will rival that of Japan.
As if her spastic energy, strange customs, and mechanical knowledge were not strange enough, Su also possesses the ability to transform into a more adult looking version of herself on a single night every year, when the moon glows red. In anime she admitted to have fallen in love with Keitaro while she was in this form, despite her transformation just last a few seconds because there was no red moon. Though this is not explicitly stated in the manga, it is implied extremely heavily with the adult Su even kissing Keitaro and proclaiming herself his girlfriend afterwards.
Her room in the Hinata Inn is a faithful recreation of Molmol's natural habitat, complete with banana trees, a waterfall, and a small lake, along with a high-tech laboratory. In the anime television series,
Su is voiced by Reiko Takagi in Japanese and Wendee Lee in English.
