After Sakura Taisen 4, during a training session, it was discovered that Kanzaki Sumire's spirit power had significantly decreased, falling below the necessary levels to operate the Koubu-nishiki. As a result, she decided to step down from her role as a member of the Kageki-dan while still maintaining her position as "top star" in the dai-teikoku gekijyou.

Sakura Taisen: Sumire is set after the events of the game Sakura Taisen 4: Koiseyo Otome. It was made to celebrate Sumire Kanzaki's voice actress, Michie Tomizawa, retiring from voicing the character in 2002.
