Kaolla Su

Voiced by: Reiko Takagi (Japanese), Wendee Lee (English)

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.

She is from the fictional kingdom of Molmol, supposedly located near the International Date Line, and is the princess of said country. The dot on her forehead seems to have something to do with the 3-eyed symbol of Molmol, though it resembles (indeed, is almost identical to) a bindi dot. She is seemingly a barefooter and is very rarely caught with any kind of footwear on. She is often 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.

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: 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. This can be seen when she states that she likes them both, but later comments (in the anime) on how Keitaro would never say something like "You have no choice", implying that she feels Keitaro is kinder and more considerate of her feelings than her older brother.
