Random observation of the minor details in this episode:
So, on a second watch, it would seem that Zessica actually saves Amata's life multiple times, if you watch carefully, when he's falling, he doesn't actually hit the ground and the air distorts directly below him just before he hits.
... Thinking about it, that's probably how he survived slamming into/was able to have his body bend steel.
Another random detail:
Kagura's power doesn't on work on those without attachments.
Mikono's power is about forming attachments.
