"Congratulations, Liam," praised Shiranui, having watched the battle on a TV in Lumiose City.  His research on Hoopa was so far fruitless until a golden ring containing a portal appeared.  A note fell out and Shiranui read it.

"[I]HOW DO YOU LIKE YOUR GIFTS MOON CHILD?
I PICKED THEM OUT JUST FOR YOU AND YOUR FRIEND
I WILL CHALLENGE YOU TO A BATTLE IF YOU FIND ME IN THE PALACE
GOOD LUCK!

Shiranui knew of the palace referred to in the note.  With the lead in his mind, he set off southwest for the Parfum Palace.
