Yuki and Yuuki are siblings who escaped in the original breakout made by Pidgi and have traveled together since then. During that time they have acted as guardians of a forest, random birds of awesome, and traveling guards. They recently learned of the destruction of several Vaeiiran bases and this has caused them to enter into public more and more. They are currently in Celadon city after defeating six Rocket operatives at once.
