Yasuki's Evolution

Sitting in his house, Yasuki was at his desk writing on a scroll, a letter to a friend and rival and the letter said: Raido, I hope this finds you well. I've decided to take you up on your offer for training cause i've gained a new power and i want your help to control and tame it. If you want you can pick the location for the training cause i'd like it to be secluded,the wolf i'm sending with the scroll is Russo you can give him your reply" then he summoned Russo and gave him the scroll and told him to "go find raido and give him this scroll" and with that Russo jumped out of the window and wnet on the hunt.
