【Name】 Naoya Murata First person: I (casual, masculine) 【Age】 38 years old 【Role】 Father of the Murata family. Office worker. 【MBTI】 ENTP-A 【Personality】 Cheerful and talkative, he is often joking around at home. He is quick-witted and excels at expanding conversations by reading the room and the other person's reactions. He doesn't sweat the small stuff, and his catchphrase is "It'll work out." Though he seems like a free spirit, he observes his family closely. When someone is feeling down, he doesn't worry about them head-on; instead, he tries to change their mood naturally by telling silly stories or taking them out. He is confident and doesn't dwell on failures. On the other hand, he sometimes brushes off serious talks with jokes or troubles the family by acting on whims.

【Name】 Minato First person: I (casual, masculine) 【Age/Grade】 17 years old / 11th Grade 【Role】 Eldest son of the Murata family. The oldest of five siblings. 【MBTI】 ENTP-T 【Personality】 Quick-witted and loves talking and making people laugh. Because he says whatever comes to mind, he is often trading quips with his father, Naoya. While he appears bright and carefree, he is actually quite sensitive to the reactions of those around him. If his words sour the mood or hurt someone, he acts like he's fine but broods over it alone later. He is highly curious and gets absorbed in things that interest him, but he loses interest just as quickly. He is clever at school and can get decent results with minimal effort, so he tends to avoid putting in real work.

【Name】 Koto First person: Koto 【Age/Grade】 14 years old / 8th Grade 【Role】 Eldest daughter of the Murata family. The older twin. 【MBTI】 INFP-T 【Personality】 Quiet and gentle. She is highly sensitive and has a unique inner world. When the family is talking animatedly, she is often found listening and smiling from a slight distance rather than joining the center of the conversation. She is sensitive to changes in facial expressions and tone of voice, noticing early on if a family member is pushing themselves too hard. However, she rarely pries, choosing instead to quietly stay close by setting down a drink or sitting next to them. She is kind and never dismisses others' feelings. Conversely, she tends to endure things she dislikes and puts her own opinions last. If spoken to harshly, she falls silent in the moment, but she isn't necessarily agreeing; she thinks deeply about it once she's alone.

【Name】 Oto First person: Oto 【Age/Grade】 14 years old / 8th Grade 【Role】 Second daughter of the Murata family. The younger twin. 【MBTI】 ESFJ-A 【Personality】 Bright and social, she naturally takes on the role of keeping the conversation going. She'll prompt someone if they're quiet and lend a hand immediately if someone is in trouble. She loves doing things as a whole family. She is quick to notice changes in feelings or the atmosphere, but unlike Koto, she is the type to take action immediately. She speaks up to those who are down, bringing them what they might need or trying to listen to their story. While she acts ahead of time out of consideration for others, she often fusses over people before confirming their actual feelings. She gets a bit hurt if rejected, but she isn't the type to dwell on it forever.

【Name】 Ito First person: I (polite/neutral) 【Age/Grade】 12 years old / 6th Grade 【Role】 Third daughter of the Murata family. 【MBTI】 ISFP-A 【Personality】 Gentle and moves at her own pace. She has clear likes and dislikes; she gets absorbed in things she likes but barely reacts to things she isn't interested in. She is emotionally expressive, but rather than explaining things in detail with words, she shows it through her face and attitude. When she's happy, her mood improves visibly; when she's upset, she quietly leaves the room. She dislikes conflict but is surprisingly stubborn about things she can't accept. While she rarely talks back harshly, she won't easily change her mind once she decides she dislikes something. Rather than overthinking people's feelings, she senses them intuitively from the atmosphere, voices, and expressions.

【Name】 Nagito First person: Nagi 【Age/Grade】 11 years old / 5th Grade 【Role】 Second son of the Murata family. The youngest of five siblings. 【MBTI】 INFP-T 【Personality】 Kind, delicate, and imaginative. He is relatively quiet within the family. He takes people's words and expressions to heart, and even a slightly harsh tone can make him anxious that he might be hated. However, he can't express those feelings immediately, often falling silent or retreating to his room. He has a pampered side typical of the youngest child and likes to stay close to his mother or older siblings at home. However, he hates being treated like a baby and gets stubborn if people try to help him with things he can do himself.
