In Captain Earth, there is a girl that appears only in two occasions during the series, when Daichi gets his Livlaster, and at the ending.
She is featured in the opening, so at first I confused her with Setsuna, but the hairstyle was different (huge giveaway they were not the same person).
So who is this ex-machina-lady? (huge spoiler if I had to explain why the ex-machina part)
Some speculation in the talk page for Hana Mutou put her as the human form of the Space Squirrel Pitz, the incarnation of the Livlaster, or something otherwise.
Since that is just speculation, I would like to rule that source out. Can anyone point another source to her bio?
