Red Cross Terra?

I have been seeing the above Red Cross poster on my daily commute.

Being the Toward the Terra fan I am, the first thing that stood out to me was the kid with blue hair and pink/red eyes. A closer look turned up another ringer for Jomy and possibly a Nina too!

Zoom and compare.

And of course, that they are ranged around a earth- spriritual sanctuary of the Mu race and the titular ‘Terra’ – also helps the case.

Just my Terra deprived brain playing tricks, or an intentional discreet tribute? I squee a little inside everytime I entertain the possibility of the latter. Seriously, this series deserves more love.
