There's a cute sequence later where Iori gets all flustered at how badass Yuki is and is very obviously crushing on her.

As well she might! Yuki being a badass is delightful. (I'm also glad to hear the rampant shippability isn't just through my eyes.)

I'm also enjoying the sentry guns! I was really confused at one point when the battle ended between my turns and I went 'wait, I wasn't doing anything?' and then realised my sentry gun had wiped out the last enemies for me.
