Kazumi's daughter, Emiko Adachi swore to avenge her death, by embracing the darkness and becoming the new Green Arrow after her half-brother Oliver Queen was incarcerated. Emiko found out the truth that it was Dante who had Kazumi killed, and wanted her to embrace and lead the Ninth Circle and killed Dante in revenge.
As noted by Oliver, if Kazumi was still alive today, she would become completely disgusted not only by every immoral action Emiko had committed all the years, including her indirect role in her father Robert Queen's death, but also disgusted by the individual she became, as Kazumi had raised her daughter to be a good person, not the cold-hearted psychopathic villain she became.
- Kazumi is one of two known women whom Robert Queen had an affair with; the other being Isabel Rochev.
