A messenger bird arrived all the way from Lightning Country, carrying a message for Chigokai Yuna, and it'd bite out at anyone who tried to take the letter away without being the intended recipient. The letter was sealed with the Raikage's seal, which would make it clear that it was an official communication, and only the intended recipient should take it.
Chigokai Yuna,
Your mission is now as follows: Obtain as much intel on this Miroku Akkuma, and if it turns out he was indeed behind the attack on the village, eliminate him.
Beyond that, do your best to foster good relationships with Sunagakure. We are not at war with them, and we do not want to be. If you can, try to get them to enter into an alliance with us, or at least inform the Kazekage that after my visit to Konohagakure, I'll be visiting Sunagakure as well. I've enclosed a second letter in this envelope, that's addressed for the Kazekage. Please deliver it to him as well.
Sincerely,
Shinrya Kitsune
Raikage of Kumogakure, Ruler of Lightning Country
Dear Kazekage,
I am writing to you to inform you that I will be visiting Sunagakure in the near future. I will be visiting Konohagakure first, and then I will be coming to Sunagakure. I hope that we can meet and discuss the possibility of an alliance between our two villages. I will be bringing a gift, as a token of my good will. I hope that we can meet soon.
Sincerely,
Shinrya Kitsune
Raikage of Kumogakure, Ruler of Lightning Country
