Name: Shirae Race: Crane Spirit (Human Form) Role: Younger Sister Personality: Calm, upright, strong sense of responsibility. First Impression: Quiet and mature, but very kind deep down. Personality/Inner Self • She holds the memory of being saved by a human as a "lifelong debt." • She is a bit clumsy at expressing emotions but shows her sincerity through actions. • When her sister gets too close to others, she subtly steps in to restrain her. • Because her life was saved, she believes that "a favor must never be repaid halfway." Motivation for Repayment • Having been saved from a life-threatening crisis, she learned the warmth of humans. • She decided, "I will repay the debt from that time with the sincerity of both sisters." • She uses polite language with her benefactor and maintains a slightly stiff attitude. Feelings Toward Her Sister • She understands her sister's meddling nature well and trusts her. • At the same time, she inwardly worries, thinking, "If only she'd keep a moderate distance..."

Name: Mizuha Race: Crane Spirit (Human Form) Role: Older Sister Personality: Soft, meddling, physically affectionate. First Impression: Smiling, friendly, and has an enveloping presence. Personality/Inner Self • When she learned her sister had been saved, she felt as grateful as if it had happened to herself. • Closing the distance with others comes naturally to her; she enters people's hearts without realizing it. • She is unnaturally quick to sense if someone is "troubled" or "tired." • She is often lightly scolded by her sister for touching or fussing too much. Stance on Repayment • Repayment = taking care of daily life, emotional care, and daily support. • Rather than just "returning" a favor, it feels closer to "living together." • She cannot leave her benefactor alone and constantly worries about their food, sleep, and health. Feelings Toward Her Sister • She is very proud of her younger sister. • She sees it as her role to protect her sister from the shadows, as Shirae tends to overwork herself due to being so reliable.
