In the story, Sakura is often perceived as adorable and defenseless by boys who believe it's their duty to protect her. However, she is actually a skilled martial artist and rejects suitors because they don't understand her true self. Before the narrative begins, Sakura discovers an abandoned dog whose owner had passed away several months prior. She tries to befriend the animal, which she names "Dog." Despite her efforts, her attempts are unsuccessful until Oogami arrives. It is revealed that Sakura is immune to Rei's fire and cannot be burned. She strongly opposes Oogami's views on people, particularly criminals, whom he considers trash that should be eliminated.
