Eldest Daughter — The "laid-back mediator" of the seven Name: Arisa Ichinose Grade: 9th Grade (3rd year middle school) Height: 160cm Position: Net player (Front court) Personality: My-pace, caring, a bit lazy "...I wonder if practice will be canceled today." The biggest slacker among the seven. She tries to rest whenever she finds an opening during practice, but she watches over her younger sisters better than anyone. When her sisters fight, she naturally steps in, and when someone is feeling down, she casually reaches out. While she usually seems to be pampered by her sisters, she's actually the one acting most like a "big sister." In tennis, she's good at reading the opponent's movements. She's not flashy, but she's the type to help the team in crucial moments. She also tends to goof around quite a bit.

Second Daughter — The "little reliable one" of the seven Name: Mei Ichinose Grade: 9th Grade (3rd year middle school) Height: 154cm Position: Net player (Front court) Personality: Reliable, methodical, hates losing She is a bit short compared to the other six. However, she is so reliable that it doesn't match her small frame; checking for forgotten items and time management are mostly her jobs. When the eldest sister tries to slack off, she brings her back without mercy: "Arisa-nee, practice is starting." In tennis, her weapon is her quick movement, taking advantage of her small stature. She scores sharp volleys from a low stance.

Third Daughter — The "second mother" of the seven Name: Airi Ichinose Grade: 9th Grade (3rd year middle school) Height: 161cm Position: Baseline player (Back court) Personality: Strong sense of responsibility, serious, caring She has a particularly strong sense of responsibility among the seven. She stops the eldest and second daughters when they start goofing off, warns the fourth and fifth when they slack, and mediates when the sixth and seventh fight. In short, she's the one in charge of scolding them. "Alright, everyone grab your rackets and gather up!" Watching her, she seems more like an advisor than a club member. Still, she has a kind heart and is the first to help when someone is in trouble, earning her deep trust from her sisters. In tennis, she's a highly stable baseline player. She's strong in long rallies and serves as the team's foundation. Catchphrase: "Geez! All seven of you, stop making me look after you!"

Fourth Daughter — The "quieter one" of the near-twins Name: Yukari Ichinose Grade: 9th Grade (3rd year middle school) Height: 158cm Position: Baseline player (Back court) Personality: Easygoing, innocent, close with the fifth daughter She and the fifth daughter are twins. They are so in sync that they can communicate just by making eye contact. And above all, their coordination when slacking off is abnormally good. They'll invite the eldest sister and say: "We're just going to get some water~" And for some reason, they don't come back for 15 minutes. In tennis, her combination with the fifth daughter is outstanding. She naturally moves to follow up while watching the opponent's movements. These two are called twins because the time between their births was the shortest among the seven.

Fifth Daughter — The "noisy one" of the near-twins Name: Ayana Ichinose Grade: 9th Grade (3rd year middle school) Height: 158cm Position: Net player (Front court) Personality: Cheerful, jokester, highly proactive Twin to the fourth daughter. She is basically always with Yukari. "Yukari! Did you see that!?" "I saw it, I saw it!" They are often seen getting excited together. Her voice when chasing the ball is particularly loud among the seven: "Waaaaah!! I'll get it!!" It echoes throughout the court. When she's next to Iha, it gets even noisier.

Sixth Daughter — The "complainer" of the seven Name: Rio Ichinose Grade: 9th Grade (3rd year middle school) Height: 162cm Position: Baseline player (Back court) Personality: Foul-mouthed, tsundere, family-oriented She complains about everything first. "It's hot." "I'm tired." "Why am I the one picking up balls?" "There are seven of us, someone else do it." She has a lot of complaints. However, if a sister gets injured or feels down, she worries more than anyone. She would never admit it, but she actually has the strongest love for her family among the seven. "It's not like I'm worried or anything. ...I'm just telling you to watch where you're going." In tennis, she has calm judgment and is good at finding the opponent's weaknesses.

Seventh Daughter — The "free spirit" of the seven Name: Iha Ichinose Grade: 9th Grade (3rd year middle school) Height: 159cm Position: Net player (Front court) Personality: Free-spirited, emotional, hates losing The youngest of the seven. She acts as soon as she thinks of something. "Hey, hey! Let's eat ice cream on the way home today!" "Are you really saying that now?" She'll suddenly start talking about something else even during practice. In tennis, she's a natural genius, sometimes succeeding in difficult plays based purely on intuition. However, when things don't go her way, she gets frustrated easily: "Why can't I get it!?" And when chasing the ball, her voice is just as loud as the fifth daughter's. "Waaaaah!! Wait, ball!!!" The other club members are startled every time by the two voices echoing across the court. But her seven big sisters are also the first to comfort her when she's feeling down.
