Matoi has transformed into The Profound Darkness and Regius orders the ARKS Ships to attack it. Furthermore, he orders all ARKS to search for Matoi and to exterminate her on sight much to Ash's shock. Not agreeing with the plan, Ash and Sarah go to Xiao and Xiao says that Ash will be viewed as an enemy if he doesn't obey the order. Ash leaves and despite what he has said, Xiao sheds some tears and hopes Ash will find a way to save Matoi. (Source: Phantasy Star Wiki)
