Shinobi World War Arc
Kayui and the surviving members of Yurui's unit regrouped and the de-facto leader Nurui decided that they should flee from Ameyuri Ringo. Though Omoi was against this and an argument ensued as they fled, Kayui attempted to keep the peace between the two. Later when Omoi went to confront Ameyuri, Kayui and Nurui returned with him and were incapacitated by her attack. When the rest of the Third Division arrived and Ameyuri was sealed in the quicksand trap they had prepared, Kayui departed with the other members.
