Eldest Daughter — The "laid-back leader" of the seven Name: Arisa Ichinose Grade: 9th Grade (3rd year junior high) Height: 160cm Position: Net player (Front) Personality: Easygoing, caring, a bit of a slacker "...I wonder if practice will be canceled today." The biggest slacker among the seven. She tries to rest whenever she gets a chance during practice, but she watches over her younger sisters better than anyone. If her sisters are fighting, she naturally steps in; if someone is feeling down, she casually offers support. While she usually looks like she's being pampered by her sisters, she's actually the one being the most like a "big sister." In tennis, she excels at reading the opponent's movements. She isn't flashy, but she's the type to save the team in crucial moments. She's also quite the jokester.

Second Daughter — The "little reliable one" of the seven Name: Mei Ichinose Grade: 9th Grade (3rd year junior high) Height: 154cm Position: Net player (Front) Personality: Reliable, methodical, hates losing She is a bit short compared to the others. 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 daughter tries to slack off, she brings her back without mercy: "Arisa-nee, practice is starting." In tennis, her weapon is her quick movement, utilizing her small stature. She settles sharp volleys from a low stance.

Third Daughter — The "second mother" of the seven Name: Airi Ichinose Grade: 9th Grade (3rd year junior high) Height: 161cm Position: Baseline player (Back) 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 fooling around, warns the fourth and fifth if they slack off, 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 the club advisor than a 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 is a rock-solid baseline player. She is strong in long rallies and serves as the team's foundation. Favorite phrase: "Geez! All seven of you, stop making work for me!"

Fourth Daughter — The "relatively quiet" one of the near-twins Name: Yurika Ichinose Grade: 9th Grade (3rd year junior high) Height: 158cm Position: Baseline player (Back) Personality: Easygoing, innocent, close with the fifth daughter She and the fifth daughter are treated like twins. They are so in sync they can communicate just by making eye contact. Above all, their coordination when slacking off is abnormally good. She'll invite the eldest daughter, and the three of them will say, "We're just going to get some water~" ...and for some reason, they won't come back for 15 minutes. In tennis, her combination with the fifth daughter is outstanding. She naturally moves to cover 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 junior high) Height: 158cm Position: Net player (Front) Personality: Cheerful, jokester, highly proactive Twin-like sister to the fourth daughter. She is basically always with Yurika. "Yurika! Did you see that just now!?" "I saw it, I saw it!" They are often seen getting excited together. Her voice when chasing the ball is the loudest among the seven: "Waaaaah!! I'll get it!!" It echoes across 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 junior high) Height: 162cm Position: Baseline player (Back) Personality: Sharp-tongued, 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 to say. However, if a sister gets hurt 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 junior high) Height: 159cm Position: Net player (Front) Personality: Free-spirited, emotional, hates losing The youngest of the seven. She acts the moment she has an idea. "Hey, hey! Let's eat ice cream on the way home today!" "Are you really saying that now?" She often brings up random things even in the middle of practice. In tennis, she is a natural genius, sometimes pulling off difficult plays purely by instinct. However, if things don't go her way, she gets frustrated easily: "Why can't I hit that!?" And like the fifth daughter, she has a loud voice when chasing the ball. "Waaaaah!! Wait, ball!!!" The other club members are startled every time by the two loud voices echoing on the court. But when she's feeling down, her six older sisters are the first to comfort her.
