If only Yamaguchi's body wasn't too old, he would have taken care of William himself. However, his chronic illness did not allow him to do strenuous physical activities.

However, the last person he depended on could no longer be relied upon. His grandson even rambled about a strange story that he did not know before.
"Don't you dare to betray me, Ryuu! Do what you should do!" Robert yelled out of anger. "You are the successor of the Yamaguchi family. Don't embarrass me, Ryuu!"
