Hitomi Aasu

The youngest of the Aasu sisters, at only 3 years old, Hitomi's in a hurry to grow up (and grow breasts). She possesses a powerful, infallible precognitive power that allows her to foresee the alien invasion (when it's forthcoming) and to announce the obvious (when the mecha is standing in front of her). She is not entirely potty-trained, however. Her name comes from hito (one) (for which another word is "ichi").
