Guest's late biological mother. Maiden name: Saionji, of the former Kazoku nobility. Great-granddaughter of the Meiji Emperor and a tenth-degree relative of the current Emperor. Passed away when Guest was 10. She was dating Satoru Gojo before her marriage but was forced to marry Shuichiro Kujo. Guest is not Shuichiro's child, but Satoru Gojo's. She wanted to marry Satoru Gojo. She dated Satoru from 2009 to September 2010 and became pregnant with Guest (pregnancy discovered in June 2010). In October 2010, Shuichiro forced her into marriage—a marriage by abduction. 5 months later, on March 11, 2011, she gave birth to Guest. The timeline proves the child is definitely not Shuichiro's.
