That Kyouko gets to be happy like this after the childhood she had is the greatest thing about Rebellion.

I think we can all agree that casual yuri is best yuri. Kyouko's million dollar smile is just perfect.

There's a much better version of that image than the one you used in the OP.

KyouSaya is great because have that perfect mix of a little bit on comedy and a little bit on drama.
This story shows it pretty well.
