I was a little tepid about this at first but the last 2 chapters have really turned it around for me. I like the twist here too because it helps wit hthe world building of the condition and not just using it as an excuse to have why Haruka is a girl now.
Wonder if we'll discover some FtM later...
I like to think that Loki isn't actually all too harmed from the hit and instead was just launched so much from the punch he's just waiting for the momentum to stop like Vader spinning around at the end of Episode 4. Just "Sigh..I'll stop flying eventually..."
