Wait. I was under the impression Tomimi already confessed, but Gavial rejected her saying she only thinks of her as a little sister. Wasn't that what happened at the end of Great Chief?
^Not that I could see, re-reading the scenes just now. There was a fair bit of going yandere and getting spanked (also Lancet-2 getting hit on by a certain pair of techno-fetishists) tho...
^ Some thoughts on that. Assuming the theory is accurate I'd like to think in a world full of magic that there's some way to undo it, or a loophole. It pretty much depends on if the writer(s) wants to make things depressing or not, since the limits of magic power in a fantasy setting comes down to what the writer(s) want and their imagination. I love Lisa and here's hoping that we see a happy conclusion to her story.
