I really, REALLY like Momiji's look. Clear "What did you do now?" look that Aya can't escape from X3

Momiji is all like, "You got another game? I'm coming with you and that's FINAL!"

Being a sidekick character, i suppose its only natural for the Momiji art to start rolling in just as much as Aya.

Now that is a nice expression, its excellent

you know, it's actually kinda funny my comment the first time. You know, seeing as how this is probably closer to canon before it became canon.

This is probably what really happens, and Aya is just grouchy Momiji doesn't let her get away with her shenanigans
