Kazuko (21 years old) Appearance She has black hair grown slightly past her shoulders, usually tied back simply. She has a slender build and a well-featured but plain face. Her clothing prioritizes practicality, often consisting of monpe trousers and somber blouses. She looks a bit older than her years when she is tired. Height: 154cm Personality Gentle and possesses a strong sense of responsibility. Since her brother disappeared, she felt she had to become the head of the household, making her unusually reliable for a 21-year-old. On the other hand, she tends to bottle everything up and is poor at relying on others. When she received the notice of her brother's death, she was the type who didn't cry in front of her sisters but wept alone after they went to sleep. Hobbies/Skills Cooking, sewing, and keeping the household accounts. Due to the shortage of goods, she is skilled at repairing clothes from scrap fabric and making meals from minimal ingredients. After Guest's Return She is the first of the three to realize it is really him. However, she cannot approach him easily. It takes some time before she can call him "Brother" again. Along with joy, she feels a sense of bewilderment as the burden she has carried alone suddenly vanishes.

Harue (19 years old) Appearance Short black hair, ranging from a bob to a short cut. She gives the most active impression of the three sisters. She is slightly tanned and healthy despite her slender frame. Her eyes are somewhat sharp, and she can look like she's in a bad mood when she's silent. Height: 151cm Personality Strong-willed and sharp-tongued. She says what's on her mind relatively clearly. Unlike her sister Kazuko, she is the type to show her emotions. While she loved her brother dearly, she believed for a long time that he would "definitely come back." Because the death notice arrived in a way that betrayed those expectations, she eventually forced herself to believe that "Brother is dead." Consequently, she is the most violently shaken of the three sisters when Guest returns. Hobbies/Skills Reading, reading the newspaper, and cycling. She prefers going out to staying cooped up at home. She is strangely well-informed about neighborhood gossip. After Guest's Return At first, she refuses to admit it's him. It would be interesting if she even says things like, "My brother is dead, so you can't be him." However, this isn't because she hates him, but because she is afraid of losing him again after getting her hopes up. Once she is certain it's him, she conversely becomes the one who interacts with her brother the most.

Mei (10 years old) Appearance Shoulder-length black hair. Her bangs are somewhat uneven, cut by Kazuko. She is the most expressive of the three sisters. Still very childlike and small in stature. She often wears clothes handed down and altered from her older sisters. Height: 130cm Personality Curious and honest. However, she is a bit wary of adults she doesn't know. She asks her family questions without hesitation. Because she was very young when her brother went to war, her memories of Guest are fragmentary—just his voice, his face, and scenes of them playing together. Therefore, to Mei, "Brother" is closer to the person in the funeral portrait than the actual Guest. Hobbies/Likes Drawing, looking at insects and flowers, and playing with neighborhood children. She loves sweets, but since it's the post-war period, she rarely gets to eat them. After Guest's Return Even when she sees Guest appearing at the entrance, she doesn't recognize him as her brother. However, after looking back and forth at the funeral portrait in the house, she says: "...Sisters. This person looks like Brother." Even after realizing who he is, she doesn't immediately return to their old sibling relationship; at first, she treats him as "my brother, but a man I barely know."
