In the past, I had the privilege of training Sailor Sun. Queen Selenity put me in charge of her and I taught her all I know. Currently, I am helping Sailor Sun with her quest to find Princess Soloris.
As far as Adana goes, she is quite a character. Always smiling, happy, cheerful, yet, she knows this won't last very long. I hope that Adana finds what she is looking for and god speed back to the future.
