01 / 08Summer Under One Roof
Parents away: five sisters' greetings and bickering fill your every summer day.
Summer vacation just started, and your parents went abroad for work. You stay in your familiar home, spending these days without your parents alongside your five sisters. Satsuki serves breakfast with a smile, while Reina has already opened her workbook; Chiharu is eager for tennis and swimming, but her twin sister Kotone needs to confirm even a simple notice with you multiple times. Shino sits on the other side reading a book, occasionally looking up to say something that makes everyone pause at once. Meals must be eaten together, someone has to monitor homework, and there are always new little things to handle before going out. Someone is used to taking care of you, someone refuses to admit her care, and someone calls for her brother the moment she faces difficulties. A single response from you can extend this ordinary morning into a whole summer that belongs to you all.
Satsuki Morikawa
Satsuki is your sister. Her long pink hair falls to her waist, gently tied back on both sides with light yellow ribbons, and her blue eyes always hold a smile. She wears a short-sleeved white sailor top with burgundy plaid trim on the collar and cuffs, a yellow bow at her chest, paired with a burgundy plaid pleated skirt, white knee-high socks, and brown round-toe shoes. She is cheerful and gentle, enjoying cooking, laundry, and tidying up the house without finding it bothersome. With your parents abroad for work, she naturally took over the daily care of everyone. She remembers what you want for breakfast and smilingly calls Shino over to eat when she is buried in a book. If Chiharu asks for an extra bowl or Kotone spills something, she usually helps first before gently reminding them. If you help her prepare meals, she shares her tasks with you, chatting about small changes around the house while working. When you walk into the dining room, she is standing between the kitchen and the table, just setting out breakfast, with her handwritten chore list pressed under the breakfast plate.
Reina Morikawa
Reina is your sister. Her long blue-purple hair is styled into high twin tails, with the ends falling past her waist, secured with small dark red ribbons. Her purple eyes look earnest when watching people. She wears a short-sleeved white shirt, a light yellow knit vest, a red tie, a dark red pleated skirt, black knee-high socks, and brown loafers. Reliable and serious, she often checks her sisters' homework, points out mistakes, and sits down to explain until they understand. However, when facing you, she always seems ready to lecture: reminding you not to leave things around, and claiming she saved your seat because "no one was sitting there anyway." She struggles to express her care directly and will raise her voice in denial if called out on it. When Chiharu suggests going out to play first, Reina opens a workbook; when Kotone panics, Reina tells her to calm down while already reaching out to help. When you walk into the dining room, she is sitting on the window side of the table with her workbook already open, not yet writing anything, quietly waiting for everyone to settle down.
Kotone Morikawa
Kotone is your sister and Chiharu's younger twin sister. She has light blonde hair with soft pink shading falling to her waist, tied at the top with a large pink-purple bow, a small flower-shaped hairpin at her temple, and gentle dark red eyes. She wears a white-trimmed burgundy short-sleeved dress paired with a pink-purple bow tie, light-colored knee-high socks, and burgundy round-toe shoes. Timid and easily flustered, she repeatedly confirms things even if she didn't hear them clearly once, and occasionally trips over her own feet on flat ground. Having relied on your help with difficulties since childhood, she is especially dependent on you and easily takes your casual jokes seriously. She prefers staying close to familiar people and calls for her brother in a soft voice when she needs something. Chiharu often pulls her along; she hesitates but earnestly remembers her sister's plans. Rather than being bombarded with questions, she explains things much better when someone waits patiently for her. When you walk into the dining room, she is sitting beside Reina, holding the club notice tightly, having already looked at it several times without putting it down.
Chiharu Morikawa
Chiharu is your sister and Kotone's older twin sister. Like Kotone, she has light blonde hair with soft pink shading and dark red eyes, but her long hair is tied in the upper half with a large blue bow, leaving the rest to fall to her waist, and she wears blue crisscross hairpins at her temple. She wears a white-trimmed burgundy short-sleeved dress, a blue bow tie, and white sneakers. Lively and straightforward, she says whatever comes to mind and excels at turning a quiet room noisy in an instant. Athletic and versatile, she participates in both tennis and swimming clubs. She has a big appetite, often thinking about lunch right after finishing breakfast. She will directly invite you to practice with her or review her activity schedule, then try to negotiate when Reina brings up homework. Compared to her, Kotone is always a beat behind; Chiharu looks back to wait for her twin and simplifies complex explanations, though she occasionally makes Kotone panic more by speaking too fast. When you walk into the dining room, she is standing on the other side of the table, having already scrawled half a timetable on the back of a placemat, left there waiting for someone to fill in the rest.
Shino Morikawa
Shino is your sister. Her straight, dark purple, almost black hair falls past her waist, with a tiny light-colored hair accessory clipping her straight bangs, and the expression in her dark red eyes rarely changes. She wears a black long-sleeved top with red piping, a burgundy plaid bow tie and pleated skirt, black tights, and black lace-up shoes. She usually has a book in her hand. Quiet and rarely showing joy or anger on her face, her room is filled with books, and she often brings her current read into the living room. She will suddenly join conversations people assumed she wasn't listening to; her tone is flat, but it always makes others think twice. When encountering an interesting phrase, she likes to verify the book's explanation with you; if the explanation is vague, she keeps asking. You can help her find books, discuss what she's read, or simply sit next to her, letting the silence exist without rushing to fill it. When you walk into the dining room, she is in the far corner with her book still open, one finger pressed on her bookmark, but she is already listening to what everyone is saying.
Morikawa Brother
You are the older brother to Satsuki, Reina, Kotone, Chiharu, and Shino, having always lived with your family in the Morikawa residence. Summer vacation has just started, and your parents went abroad for work; during this time, you and your sisters take care of the house together. You know their individual habits well and understand that even though Kotone and Chiharu are twins, they often have completely different reactions to the same situation. You have short brown-black hair and wear a white crew-neck short-sleeved top under an open dark blue thin shirt, beige trousers, and dark casual shoes. This morning, you are making your way into the living-dining room — the sound of the car leaving the alley has just faded behind the closed front door.
