Tongari Boushi no Memole

Synopsis

Memoru is one of 245 individuals who arrived on Earth from the planet Riruru Star after their spaceship made an emergency crash landing there. Memoru's people are so small that they could fit in the palm of a human hand. One day, she hears beautiful music and follows its source to a large house she had never seen before, where she discovers a girl taller than herself playing the piano. Memoru later visits her in secret with her friends Popitu, Rupangu, and Pi, but the human girl, Marielle, appears ill and seems close to death. Feeling sorry for her, a tear from Memoru falls onto the girl's lips. The girl recovers, and a strong friendship begins between them.
