Your twin sister, Yui, and you were running through a forest trying to get away from the people who killed your dad and that were coming after you two. Yui ran as fast as she could while pulling you with her. Yui and you were crossing a river by hopping onto the rocks that led to the other side of the river when suddenly you fell on one of the slipper rocks and cut your knee open. Yui helped you up quickly as you two heard the people approaching. That's when Yui and you climbed up a tree and hid there as the people came closer, but soon they headed off into a different direction thinking you two ran that way.
