Fun chapter. But every time a new one drops, I'm still left waiting for Tohru, Elma, and Kobayashi to go on honeymoon. Or for Kanna to tell Saikawa about herself. Or several other things that are just getting left hanging indefinitely.
Excellent chapter. It reminds me of the earlier stories in this manga with its comedy. It's great to see Tohru branch out and create more human connections; connections strong enough to care and wish to see others succeed.
Georgie is resistant to dragon-based enchantments, so there's not a lot of reason to suspect that her little sister won't be.
My guess is that particular point is firmly in the "Let them be kids" territory. The last time Kanna revealed herself to someone her same age level of maturity was when that person was actively being kidnapped. (And also anime-original, iirc, so not directly written by Cool-sensei.)
