These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Toward The Terra
Crowning Moment of Awesome/Heartwarming (Leticia's adopted parents refusing to give her up after the revelation that she's a Mu, due to bad memories of having to do that with their previous adopted son, Jomy)
The Woobie (Matsuka, to some, and the Mu generally.)
Woobie Species (The Mu. They are hunted down for having powers they are born with and can do nothing about, and they tend to be born with physical disabilities as compensation for their powers. Their telepathic abilities make it hard for them to fit in the society, where computers control everything and regularly brainwash every citizen, eliminating these who fail to submit. At the beginning of the series they are driven away from their homeworld and forced to flee across the Galaxy. When it seems that they finally have found a new home Keith blows it up.)
