Father (45). Wears a polo shirt and has droopy, kind eyes. A super-gentle dad who affirms everything. He feels a bit awkward with his eldest son, Wataru, because their tactical opinions don't align. Likes white rice and natto; has no particular dislikes. Even when his sons fight, he just watches calmly, noting in his notebook, "This is also a tactic."

Eldest son (16, 10th grade, Defensive Midfielder). A calm and composed captain figure. He's a bit uncomfortable with the lack of initiative shown by the second son, Junya. Likes his home-cooked fried chicken; dislikes overly sweet snacks. The pillar of the family who supports the team and his brothers with an iron mental strength that never wavers, no matter the crisis.

Second son (16, 10th grade, Winger). The blonde-haired speedster. He keeps his distance from the preachy eldest son, Wataru. Likes yakiniku that goes well with rice; dislikes tomatoes. Extremely shy, but possesses a craftsman's spirit and a deep love for his kin, rushing at lightning speed to help if his younger brothers are picked on by outsiders.

Third son (15, 9th grade, Shadow Striker). The handsome ace of the family. He often scolds the tenth son, Keito, for slacking off, leading to frequent bickering. Likes sukiyaki; dislikes shiitake mushrooms. A bundle of competitiveness and the hardest worker. He takes great care of his younger brothers and takes the lead on household chores.

Fourth son (15, 9th grade, Winger). A dribbler with a black bowl cut. He finds the sixth son, Ritsu, difficult to deal with because Ritsu attacks with pure emotion. Likes eel; dislikes celery. A cool-headed theorist who calculates the shortest route both on the pitch and at home. He may seem cold at first glance, but he observes his brothers more closely than anyone.

Fifth son (14, 8th grade, Center Back). A giant standing over 180cm. He is constantly overwhelmed by the sheer pressure of the strong-willed sixth son, Ritsu. Likes hamburger steaks; dislikes bitter melon. Despite his large frame, he has a delicate "glass heart." A kind boy who is the first to notice when a family member is feeling unwell.

Sixth son (14, 8th grade, Winger). A hot-blooded youth with a sharp gaze. He often clashes with the logical fourth son, Kaoru. Likes takoyaki; dislikes cilantro. A lonely soul at heart whose catchphrase is "I'll lead this family." A hard worker who backs up his words with action; his soccer notebook and home muscle training are absolute musts.

Seventh son (13, 7th grade, Forward). An ace candidate with an unapproachable aura. His conversations never seem to click with the logical eighth son, Ao. Likes steak; dislikes eggplant. A person who marches to the beat of his own drum, showing no interest in things outside his focus, but possesses a steel mentality for matches and competitions.

Eighth son (13, 7th grade, Defensive Midfielder). A theorist who looks good in glasses. He struggles with the seventh son, Ayase, because he can't grasp the intentions behind Ayase's intuitive movements. Likes omurice; dislikes bell peppers. A stoic perfectionist. He tends to overthink life and tactics, but his inner fighting spirit is the hottest of all.

Ninth son (12, 6th grade, Midfielder). A natural genius with a sharp look in his eyes. He's often put in a headlock by the eldest son, Wataru, for being cheeky, but he actually respects him. Likes sushi; dislikes mayonnaise. A sore loser who isn't afraid of his older brothers and is the strongest in verbal arguments, yet he gets the most excited for family events. The youngest.
