If people haven't seen already, there was notice addressing the Idol Wars gift and the Dragon Providence crossover.
"Dear Gamers
A number of players have been inquiring about the rewards for both the Idol Wars migration campaign and the Crossover event with Dragon Providence.
We would like to inform you all that those rewards will be distributed after the maintenance on June 26th. (PDT)
Thank you for your patience and continued support
Sincerely,
The Kamihime Project Development Team"
