Can't help but laugh at his death. Especially during a time when he was forgiving himself. Kind of sad, really.
But then again, loli reincarnation in your own world you put lots of effort into doesn't sound bad.
I just realised that the Moon and finger analogy can be applied here.
The finger in this case is the mother. Yuzuki's too focused on trying to become perfect like her mother. She doesn't realised yet that she can be perfect in a different way.
