I don't want to create another post for this but Kamihime producer announced something yesterday about awakenings:

"About the awakening character which we are adding at the pace of one month every month,
Delay in implementation has occurred due to partial adjustment.
We sincerely apologize to everyone who was looking forward to the addition.

The awakening character is scheduled to be added to Shinki of light attribute next time.
We are preparing to offer you in a better form to everyone,
We appreciate your patience as we wait for a while."
