Little Memole

Memoru is one of the 245 individuals that arrived on earth from the Riruru Star after their ship made an unplanned emergency landing. The inhabitants of Memoru are so little that they could stand on a person's palm. She follows the source of some beautiful music one day and finds a girl taller than herself playing the piano in a large mansion she has never seen before. When Memoru and her pals Popitu, Rupangu, and Pi paid Marielle another secret visit, she appeared ill and in danger of passing away at any minute. Memoru shed a tear for the girl since he felt bad for her. As the girl gets healthier, they develop a close bond.
