Curious question: Any thoughts on why they skipped Nagi and Miranda's events?

For Miranda, I kinda get for two reasons:
1. They probably treated Odette's revival as an actual farm event, so they wanted to switch to a star trial yet again.
2. Most likely unrelated, but they did rush on releasing Estelle to the shrine. This event was her spotlight in the original event timeline. Then again, they still haven't released a couple of blacks like Esta (black pegasus rider) and Matsuri (black front tactician).

Nagi is probably them being lazy as usual. However, her event did introduce Inari, the first unit of everyone's favorite class. She's part of the Youko class (or foxgirls if you want simpler terms).

I certainly hope they won't rush on releasing Rion for the same reason they released Estelle earlier than expected and put Inari in the shrine instead. She's supposed to appear in the event after Sandra's which is another star trial. -_-
