Kaolla Su is an eighth grade foreign exchange student who boards at the Hinata House. She goes to the same school as Shinobu Maehara.
Liking to keep her origins a secret, it was initially thought that she was from India, or possibly even Australia. However, it was later revealed that she was actually a royal princess from the Kingdom of Molmol, an island nation in the Pacific.
Possessing an Indian appearance, Kaolla is often barefoot and dressed in nothing else except her school uniform. But she does wear sneakers on some occasions. She is extremely hyperactive, usually hugging (or, in Keitaro's case, kicking) someone, trying to eat something, especially bananas and/or Tama, 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.
