Before Shougo used the forbidden art of the Arisu Clan, he asked Xiaomu to take care of his son Reiji. After ten years, Reiji finally matures into a hardened warrior. During the events of Namco X Capcom, when Saya appears before Reiji, she had a feeling that events would repeat themselves and it would affect him directly. After fighting alongside Reiji and other allies across time and space, she eventually tries to muster the courage to tell the truth of what happened to Reiji's father, but missed her chance due to her hesitance. When the worlds merged, she finally got a chance to say it, but it seems Reiji figured it out. As she pleads him not to use the forbidden art, their friends arrived in time to stop him as well. As soon as they deliver the final blow to Saya, the worlds begin to return to normal. 3 months later, the man who gave them invitations became none other than Demitri Maximoff. While Demitri's party continue on, Xiaomu and Reiji decides to talk about the future and what their adventure takes next.
