Have a great and beautiful life Nayxa ?
I hope you enjoyed your time here, I’m sure a lot of us will miss you...
I bid farewell, maybe one day, far in the future, we’ll meet again.
For now, I only have the best wishes for you.
You can get 1 Senshi book from the other Senshi by doing their quest.
As for getting the other 9 or 10 for the rest, you can roll Astral Puzzle or use AP/BP/LP for their boxes in the shop when they are up. We have a few out at the moment in shops.
