In Shin Koihime Musō, Kan'u is relegated to the position of Ryūbi's second in command and confidante. Here she is a very strict general and disciplinarian, especially towards Ryūbi herself (due to Ryūbi being a rather naive and reluctant queen), and Kazuto (likely out of jealousy over Ryūbi's closeness to Kazuto, since she herself in fact harbors romantic feelings towards him).
