Well if that is the case, the story would have returned to the silliness of the beginning.
But this and the last one makes me think that Keine use to be someone else as well, or had met the fairy that Yuuka once was and both don't remember it very well.
Very few stories have such a beautiful setup such that every step of the way you can look back and say, "Okay, I know this, this, and *quickwiki*this. Does that mean this happens next?". For this whole dramatic fight and revelation, Akyuu still doesn't revise the entry for Yuuka. That means Yuuka is going to end up causing or being involved in some major damage soon. Cirno is the only one who hasn't been shown after the fight, and seemed to be in the most unstable state physiologically, perhaps on the border of a transition similar to Yuuka's. Yuuka mentions that she regrets accepting the position as a teacher. Perhaps she realized what was happening with Cirno, but because the process was not a calm, drawn-out one surrounded by caring friends like her's, the end result could end up being very different. Whereas Yuuka wanted friends, closeness, and peace, and ended up more or less with a very stable control over her abilities over a long period of time, Cirno just exhausted herself in a major battle very quickly, the whole time with the singular thought of not being looked down on. Of being stronger. If any kind of evolution is going to take place, I have a feeling it's not going to be a pretty one. At the very least, it's going to leave a permanent mark on Yuuka's record.
"The kids are raising them, so ones that are healthy, don't wilt easily, and are easy to take care of would be good."From then on,That teacher started to frequently come and visit me.She would talk to me without fear, even like a friend.
I felt like I was remembering something I had forgotten.
And one day, Kamishirasawa Keine said this:The teacher told that to me, then happily returned home.I didn't know what she was thinking, but I decided to go along with it.I first met Kamishirasawa Keine in this flower field."There's something I want to ask you."I remember she talked with me."Would you like to try being a teacher for 3 days?"She said that she wanted me to teach the kids how to take care of flowers.I accepted.And I think nowI should have refused.
