I just have two observations about them in the UF
universe.

1) Writing Hikaru as a Salusian must have been a
complete no-brainer given the number of times she appears
with two "primary" ears in the original story.

2) I can see how Azalynn's character was based of Koalla
Su :) They both have a bit of "little girl" immatureness
in them. They both are always smiling and happy no matter
the circumstances. :)

Just my 1 cent :)
