Lucy is an alien girl who doesn't have much expression and doesn't have any friends. In the anime, she introduces herself to Takaki's class as 'Ruuko Kirei na Sora', which means 'beautiful sky.' She meets Takaki in the sixth episode of the anime, but we see her in an earlier episode without any dialog. She refers to herself as 'Ru', the name of her home planet and the beings on it, and to earth and earthlings as 'Uu'. She greets people by reaching for the sky and saying, 'Ru!' Himeyuri Sango in particular enjoys mimicking Lucy's greeting. Lucy has a cat that almost drowns in the sixth episode but it is saved with the help of Takaaki; Lucy summons a thunderbolt which splits a tree, forming a bridge which Takaaki crosses to lift the cat out of a raging river. Lucy terms this stray cat 'the Nya', saying that it is a special species that can enjoy the true taste of food, and like Ru, Nya is alone on Uu. Lucy likes to cook the Nya fish broiled over a charcoal clay pot, which according to her is the best cooking device available on Uu. Apparently a currency of Ru is matchsticks, one of which is enough to buy a whole rocket engine. Lucy irritates the cafeteria cook of Takaaki's school by attempting to treat Takaaki to the best meal the cook can prepare by paying the cook first one, then two matchsticks, however Lucy is somehow able to successfully purchase her charcoal clay pot and fish to br with matchsticks. Lucy says that on Ru, it is said that the only good Uu is a dead Uu, but Takaaki is a special Uu.
