@ Yukarin and Triangles,
At the risk of looking stupid I have to ask, are you both just referring to the one from just above my post (which I actually know is from Avatar: TLA) and not
the purple shaded yuri themed pic from page 4? I remember some bits (but not much) of Avatar: TLA but don't remember any yuri themes at all, plus the styles are way too different.
Can't say I'll be watching them though, it's $147 for all of Books 1, 2 & 3 down here (49 each, Aussie land)
Erm just to keep barely on topic, and since the DX1 dance party gif I tried to find seems to not exist, google threw this at me:

and then said

Bloody DX3 >_> [yes I'm done]
