Kaolla
From Love Hina Wiki
Her full name is Kaolla Su, or Kaolla Suu. Aged 13 at the start of the story, she is in eighth grade, at the same school as Shinobu but a year above her. She is something of a prodigy, with a knack of producing technological devices such as giant mecha-turtles, but is also hyperactive and with a childish outlook - except when there is a red moon,in which she transforms intoan exotic beautiful woman as commented by Keitaro.Initially she is a mystery, an exchange student from an unknown foreign country. There is speculation that she was from India. However, it turns out later that she is a princess from the Pacific island nation of MolMol, which is somewhere near to Pararakelse.
In the anime she has an older sister called Amalla who is Mutsumi's next door friend. In the manga the flagship of the MolMol air force is an airship called the Amallan Kaollan, presumably named after the two sisters.
In the anime she also has a "brother" named Lamba Lu - possibly a relative, but not actually a brother, who bears a remarkable resemblance to Keitaro though with a slightly darker skin tone and a more assured, confident bearing and less clumsiness.
