The Hana Kimura Memorial Show was a Japanese professional wrestling memorial show and pay-per-view event promoted by Kyoko Kimura to commemorate the one year anniversary of the death of her daughter Hana Kimura, who committed suicide on May 23, 2020. The event took place on May 23, 2021 at Korakuen Hall in Tokyo, Japan with a limited attendance due to the COVID-19 pandemic. Kagetsu and Hazuki, who both retired in 2019, made one-off in-ring returns at the event, participating in both the semi-main and main event matches.
