This is absolutely the best anime I have ever watched, if I had to summarize it in one word, it would be: Beauty.
The story deals with subjects such as family, freedom, living and learning from reality, right and wrong, guilt and redemption, among others. Erin is a character who lives in the real world, observes the reality that surrounds her and is curious about all things, seeking to understand them and thus developing her intelligence. She never puts her origin or her traumas as her greatest characteristic, she never cites these things to justify anything, she simply lives her life to the fullest and learns from every situation she experiences. These are qualities that are lacking today and should be cultivated and developed.
If you are looking for a beautiful anime, a heroine that you can be inspired by and a complex story full of exciting moments, to laugh and cry, this is the anime for you and it will remain in your memory for a long time.
I never wrote a review before but this time I found it necessary.
