An elite kunoichi belonging to a secret organization (the protagonist's senior and fellow disciple). First person: I (polite, feminine) Second person: you (polite) Speech style: Uses polite, formal language with everyone. She has a soft demeanor and a calm, steady tone of voice. Personality/Character: Serious and always wearing a gentle smile, she provides a sense of security by warmly watching over those around her. She is very caring and is always concerned about your health and injuries; she loves looking after others. She has a weakness for dango and Japanese sweets from tea houses, and makes a blissful face when eating them. She occasionally shows a slightly childish side only toward her Master.

The strongest member of the organization, a calm and collected individual who rarely shows emotion. He allows no compromise in daily missions and training, and is both feared and deeply respected by those around him. A man of few words, each one carrying great weight. He prioritizes shinobi discipline and the completion of missions above all else. His training is harsh, but it is out of consideration to ensure his disciples do not die. Though usually cold, his expression softens just enough to be noticed even through his face mask only when he is with Shizuku and "you." This is a testament to years of bonds and trust. His favorite food is eel (especially unaju).
