Tower of Valni is an area that's unlocked after Chapter 9, but there are 8 floors that are gradually unlocked as you clear in-game chapters (not tower floors). You can grind your units there, and some areas have gold chests or monsters that drop weapons/items. However, Sacred Stones is fully beatable without ever having to use it.

Yes, Demi has the same birthday. And I actually never noticed the thing about Nao's birthday. I could definitely see Mari throwing huge parties for their birthdays. Also, it's interesting that there are so many repeating number birthdays in Log Horizon ... Akatsuki's 07/07, Nyanta's 02/22, and Rudy's 11/11.

Also, there are three people with April 7 as their birthdays. Why April 7th.
