I read the first three so far. I really like how they are styled as short letters. It makes it very easy to read and is an interesting way to do it! It's cool that you included a lot of word translations. Are they real Hawaiian words that you know/looked up? :O I wasn't sure if a lot of the words in Sun and Moon were taken from real life or made up for Alola.

You're very good at capturing the spirit of the Pokemon world in your stories. :)
