The messenger would make rather good time in arriving in Amagakure. Upon arrival the messenger would make it clear that he had a message for the Joutenkage from the Rakuenkage, and if shown to Dray he would present the following message before leaving:
Joutenkage,
I have received your letter, and understand you wish to eventually visit Hinowa. When you've decided on an exact date you wish to visit please send word.
Sincerly,
The Unconventional Rakuenkage
