Souji informed Oni that his sister was last seen with the Uchiha duo of Shadou and Shayde who had went to take care of some village business. Oni, not having a close relationship with either of the Uchiha’s suddenly developed a sense of urgency and stormed out of the village as quick as he could in hopes to locate his sister and the two Uchihas. After hours of searching, Oni discovered what appeared to be a female shinobi laying in a pool of blood out in the wilderness. The deceased female shinobi would end up being his sister. Oni broke composure and snapped. The two Uchiha’s were missing, meaning that they were either suspects or had died as well in the mind of Oni. Not having any leads on what went down, Oni held the two Uchihas responsible for the death of his beloved sister. In fear of what he may do if he ever returned to the village and discovered that the two Uchihas were still alive, Oni set off from the village after giving his sister a proper burial.
