Solitary Turret under the Moon

The song is inspired by the tragedy of Sen Hime at Himeji Castle. Due to a political marriage between the Toyotomi and Tokugawa families, she later had to live with the pain of being caught between the boards.
When Sen Hime was 19, Osaka Castle fell during the summer campaign, and her husband Hideyori and mother-in-law committed suicide. This led to the Sen Hime Incident,
I am trying to express Sen Hime's feelings of misfortune and grief.
