1 - Alhambra, out-of-the-way room
[During the attack on Alhambra, Kagura's concern was, primarily, with the Graveyard personnel. Mute as she is, she managed to get people to pack up and safeguard everything important and evacuate in time for the damages to the base and their labs to have minimal effect on Graveyard material.
The problem is that among the damaged areas was Kagura's room. Which means she no longer has a locked place to hole in.
So at one point, if you're wandering around the most remote areas of the base, you might hear a male voice shouting. Closer inspection reveals Kagura in front of a screen, being absolutely ripped a new one by one of her superiors. The words "against intent of orders" "risk" "insubordination" "liability" "we can have you scrapped" "never fly again" and so on are used a great many times, while the fairy simply stands there and takes it. Not like she can defend herself, she can't even talk. So she's standing at attention with a fixed frown - so fixed, in fact, it's kind of disquieting. In the end, the commander signs off, and Kagura relaxes, floating down to a table with a thoughtful expression.
She makes some tiny scratches on a piece of paper with a mechanical pencil's small lead bar. It looks like some kind of diagram - it's very, very little, since Kagura has small handwriting even for her size, but there seem to be initials, relation arrows, and X marks on some. And she's so absorbed that she hasn't even noticed you.]
2 - Gym, late at night
[Late at night, if you go near the gym, you might notice a light turned on. Going in makes it clear nobody is using it, though...
...until you decide to look on one of the tables. Kagura is on it there, using bottlecaps as weights, surrounded by open handbooks on muscular rehabilitation. The effort has opened a few of her old wounds, but the fairy is too focused on keeping going despite the pain to care about the little drops of blood dripping on the paper.
She does notice someone coming in, though, which makes her drop the weights with a startle and turn around to look at you accusingly. Is there no bloody privacy in this place, seriously.]
