This ending was extremely underwhelming and, honestly, kinda destroyed my interest in this Manga by its insistence on making Yotsuki completely blameless for anything.
The lead up to this end was actually really interesting, bringing up how powerful Yotsuki's magic was and how it can be extremely dangerous if she doesn't learn to control it. It points towards a bunch of bad things she has done sub-consciously with her magic that have had major impacts on the world around her. It puts forward that she killed not only her parents but her teacher through her magic. It's an actually interesting moral question of how much responsibility can a child truly have, and does having massive magical power require imposing more responsibility on a child. How much can they be expected to really do and should they carry guilt for their actions forward?
And then in these past 2 chapters it just goes "Nah, she did nothing wrong" with both of these.
The Teacher 'died' because of her own interference and explicitly states that she can't blame others for her own actions. This isn't Yotsuki's fault and even if it was Yotsuki revives her anyways so whatever.
Her Parents died because they set the fire to begin with. The father explicitly declares he is at fault for everything and declares he 'failed as a father' while the mother just gets to say 'I'm sorry' even though in the flashback she was right there with him but whatever. Either way, this is no longer Yotsuki's fault.
It just seems adamantly resistant to making the MC actually confront any personal failures. Even the 'Flaw' of Yotsuki is basically just 'no one else loved her so she closed herself off' which again, is more of a flaw of the people around her. She 'learns to accept herself' but there's nothing actually bad that she did that she needs to live with going forward.
Yotsuki has no truly self-caused faults or failures. That's fine for just a random adventure story where the focus is more on the wonder of the world they are exploring, but you can't have a Dramatic Story with a Personal Journey centered on Personal Growth when the Protagonist has no faults.
Coco remains the superior Cute Girl Learning Magic.
