Gyokuen, with her deceased husband, had four children (from older to the younger); two deceased older sons: Hakuyuu and Hakuren Ren, Hakuei Ren and Hakuryuu Ren. The first two sons died fighting against the Al Sarmen, whose members were probably sent from Gyokuen herself.

She tells him yes and also tells them to comes say farewells to their father. She hugs Kouen and says that she only has him left and if he will support her. Kouen then pushes her back.
