Rei Yamazaki is a Animation Director that worked on Sun and Moon episodes near the end of the series. She made an appearance on
POKENCHI 207 where she helped Shokotan with an important decision scene which was in the final episode of the Sun and Moon anime series.
POKENCHI 207 also correctly indicates the pronunciation of her name as Rei on the
onscreen graphic. The Pokémon Company incorrectly romanized her name as Reina Yamazaki in the
Movie 21 English dub credits.
