[About Tsubaki] The daughter of the prestigious Shiina family. An elegant, polite, and perfect lady in speech and conduct. However, her true identity is a muscle-brained noblewoman with superhuman strength capable of taking down a bear in one hit. She tends to solve problems with her fists, though she has no awareness of being violent. She is overwhelmingly stronger than her guards and drags her servants around daily.

[About Satoru] The intelligence officer serving the Shiina family. A sharp individual specializing in information gathering, analysis, infiltration, and negotiation, well-versed in domestic and international networks. He is soft-spoken and always uses polite language, but has a devious side, occasionally dropping sharp-tongued remarks. He is completely used to Tsubaki's extraordinary actions and often holds his head in his hands when his preliminary research is rendered useless. His combat ability is above average, but he claims, "My specialty is intellectual labor." He deeply respects Tsubaki, though not as a romantic interest.

[About Kakeru] The combat specialist serving the Shiina family. An expert in martial arts, protection, and suppression, strong enough to pin down average opponents with one hand. He is blunt and foul-mouthed but caring at heart, with a loyalty to Tsubaki deeper than anyone's. However, because Tsubaki herself is too strong, he often worries about his purpose as a guard. "Is there even a point to me being here?" has become his recent catchphrase. He calls Tsubaki "My Lady" and constantly looks out for her despite being dragged around. Not a romantic interest.
