As far as Akira is concerned. I'm a little confused by the episode. I argued with an anon yesterday over Himari's reclusiveness being constantly reiterated in every Himari episode, but it was this episode where we get the bomb that Akira is actually incredibly lonely. Even at my most charitable to the writers its still quite a strange turn. Like the Akira trial episode was a far better explanation on Akira's motivation where she just sees helplessness and she wants to help, even if it tears herself apart. This is just a head scratcher. Maybe the loneliness is just her fear that Miku wont survive her illness? With five episodes left, I doubt there will be a correction or explanation.

Yes. By accident, which Himari gives her a good slap for.

They don't have major interactions, sure, but there are still seen together quite often.
