Hide my head I want to drown my sorrow; no tomorrow, no tomorrow

Despite being so fragile, so transient... the years and months composing ten billion years ...are, to the point of sorrow, endearing

Misanthropy is a general dislike, distrust, contempt, or hatred of the human species or a disposition to dislike and/or distrust other people's silent consensus about reality. (Wiki ).

We are told absolutely nothing about LaLa-Ru. She speaks in monosyllables, barely above a whisper, and her expression is unchanging, belying any emotions she may, or may not, be feeling. What she does make clear is her resentment for mankind's greed, possibly mankind itself. For whatever reasons, whatever she is, LaLa-Ru controls the element of water, which is what the dry earth desperately needs.

LaLa-Ru knows what Hamdo wants and knows of the war and strife happening for the sake of the water which she refuses to give-- and she doesn't care. Human affairs are of no concern to her. Though her eyes sometime mirror fright (Hamdo is insane and frightening) she does not budge in her resolve. To use the water would mean she would have to sacrifice her existence, and she refuses to give up living for ungrateful humans. Until she meets Shuu.

Shuu ends up in Heliwood trying to protect LaLa-Ru. Most of the fighting he does is to get to LaLa-Ru and protect her.Surrounded by selfishness and greed, she cannot understand why Shuu would act so unselfishly. Then he gets LaLa-Ru to Zali Barth. Even after the children and Sis learn her true identity, Sis calls LaLa-Ru her daughter, guards her from Elanbu and the children still want LaLa-Ru to play with them. When the men come to ransom off LaLa-Ru to Abelia, Suun stands in front oh her, arms spread- ready to be hit or shot, as long as they don't get to LaLa-Ru. LaLa-Ru is compelled to use her abilities to summon a blast of water to protect Suun; I think this is the first time we see LaLa-Ru use her powers. Sis and the kids know LaLa-Ru is, inadvertently, the reason their villages have been destroyed and their families murdered by Hamdo, but they do not blame LaLa-Ru, they realize she s just as much a victim as they are. This is how LaLa-Ru learns of human kindness. And when Shuu's life is being threatened she finally releases the water to save him, for a change. She lets loose a complete deluge. Once it is done, atop the flooded Heliwood, LaLa-Ru rests her head on Shuu's shoulder watching the sunset for a final time, and fades away. She knows there are good people in the world, people like Sis, Shuu, and the children, who are innocent and have good hearts, and in saving them, her life is not spent in vain.
