Junna ponders on big sister huh? Still too little to tell but you can probably make alot of guesses. It might also just be a red herring and is more-so pointing towards Junna's desire for a proper connection/friend/family that she doesn't get in Barren Hollow's Demon Maze compared to the now with Hane.

I did wonder if the title had become an artifact at this point. Perhaps the original concept was going to have alot more moments similar to Chapter 0 and Chapter 1 where Hane would cause Junna to swoon but it seems quite clear that Hane is the main draw of the series with her fast growth/change of demeanor contrast within one year being the appeal. Coupled with the author wanting to try having the two protagonist occasionally switch on who is the dominant one, and thus we have a string of Hane tripping herself over for Junna while she is none the wiser. I guess to be fair, it has been 21 chapters in snippets and given that we will have an antagonist coming up (likely a former coworker in Barren Hollow's Demon Maze), there is many opportunities to return back with Junna crushing more obviously on Hane.

I do have one outlandish theory if maybe it would end up being reversed. That given how Hane is willing to bear the sins for Junna, that she could end up becoming the evil general while Junna might rediscover herself being a magical girl before, and thus it's another cycle...but yeah, it's falls apart if you think even a little bit about it.

Junna what do you mean you can’t remember if you had a family like that. Did becoming an evil general involve receiving a total memory wipe?

Junna seems to forget how weak her bones are.

She will end up bedridden with a broken pelvis if she keeps teasing Hane like that

We don't know how long it took for Junna to go from magical girl to evil general, what they did to turn her or since when she is back to public life.

Perhaps it took a single day [I would like to point out that evil Junna wears a blindfold when transformed, despite eye-contact seemingly being necessary for some of Junna's abilities, but it's missing upon being beaten by Hane, potentially symbolising the breakage of some form of mind control, or maybe it symbolises Junna losing/taking off her blindfold during the battle, who knows].
Junna being an active magical girl and rescuing Hane was "a few years ago", so she could've been brainwashed/tortured for years for all we know [like Sonic the Hedgehog, not a good fictional example]. Prolonged trauma and/or C-PTSD can cause memory loss, even to memories unrelated to your trauma [like for Edelgard von Hresvelg, good fictional example].

Either way, now I'm curious if Kurosawa Junna is Junna's actual/original identity.

TLDR: Mind control, post-traumatic amnesia, perchance

Also I like that evil Junna retained the fuzzy "collar" she had as a magical girl, didn't notice that before.

She will die a hero's death...

Death by Snu Snu.

Hang on, what was that last panel?

Junna's former underling maybe.
Time for Hane to meet her sister-in-law

She sure has grown.
