[Kikuchi]

Nice ep, though kind of depressing...

Spoiler for Alto & Sheryl:

Things are not shaping well for them. Alto is clearly more concerned about Ranka during most of the ep and thus Sheryl definitely believes that Alto is acting nice to her out of pity.
She happens to be there when he talks of Ranka to Klan (see lower) and start crying, then throw a paper plane... which crashes. Ep ends on that scene.

Spoiler for Brera & Ranka:

Brother-sister connection confirmed. However, she is caught by Vajras and Brera is found and "reset'ed" by Grace. He's now totally under her control, an empty shell.

Spoiler for Alto & Ranka:

Alto tells Klan that he's going to kill Ranka if she ends up being used by the Vajras. Which could, ironically, be the case as she's just been captured.
Klan asks him he made that decision out of love for her (「それはお前の愛か?」, question to which he does not answer.

Quite a grim episode, for everyone.
