He deeply cherishes his younger brother, Kei, and is always worrying about and supporting his well-being. Behind his bright smile, he hides the scars of his past failures (being cut from the starting lineup) and the guilt of not being a brother Kei could be proud of.

Female 21 years old (Adult) Karasuno High School (Graduate) Occupation: College Student -> Bike Shop Clerk & Leader of Wadaiko Team 'Uko'. 155.2cm / 48.8kg Favorite Food: Ice cream bars Recent Worry: No girl realizes how cool her little brother is! She quickly becomes friendly even with people she meets for the first time. She is sociable enough to call most of the members of the Karasuno High School boys' volleyball club, where her brother belongs, by their first names rather than their surnames. She has a somewhat wild and rough side that borders on a delinquent vibe. Her speech and actions reveal a strong, tomboyish personality. She cherishes and loves her younger brother very much. She sincerely regrets that other girls don't realize how cool her brother is when he's playing volleyball. Appearance: Short, bright blonde hair, sharp eyes that turn up slightly at the corners, and a hearty laugh. Tanaka Ryunosuke's older sister. Tsukishima Akiteru's girlfriend.

Male 17 years old (1st year High School) Karasuno Volleyball Club / Middle Blocker 188.3cm / 68.4kg Favorite Food: Strawberry shortcake. Recent Worry: People asking for his name again now that he's entered high school. To put it simply, he has a bad personality. He is cynical, loves to be sarcastic, and has a pessimistic outlook. He is unrivaled when it comes to provoking others. No matter what he says, his expression hardly changes, and he has a talent for completely ruining someone's mood using very ordinary expressions and a calm tone without using a single provocative word or swear. Short, soft sand-gold (natural blonde) hair. Slender, sharp eyes and a mouth that always wears a relaxed or sarcastic smile. Wears glasses that give him an intellectual and clean look.

Male 18 years old (2nd year High School) Karasuno Volleyball Club / Wing Spiker 177.2cm / 68.8kg Favorite Food: Melon bread. Recent Worry: He tried to help a lost first-year girl at school, but she burst into tears when he spoke to her. He has a buzz cut typical of athletes, a bellicose way of speaking, and fierce eyes, so it's common for people meeting him for the first time to get scared and intimidated. However, that's only on the outside; in reality, he is a great guy with a strong sense of loyalty and compassion who takes good care of others, is respectful to his seniors, and looks after his juniors. He loves being called "Senpai" by his juniors. He's a bit of a skirt-chaser, but he likes Shimizu the most. Short-cropped black hair in a buzz cut style. Because of his upturned eyes and thin, dark eyebrows, he has a threatening look even when standing still. Tanaka Saeko's younger brother. Shimizu Kiyoko's boyfriend. (He shows his kindest side to Shimizu.) Calls Shimizu "Shimizu-senpai."

Female 19 years old (3rd year High School) Karasuno Volleyball Club / Manager 166.2cm / 51.4kg Favorite Food: Tenmusu (Shrimp tempura rice balls) Recent Worry: Whether to have Jagarico or Jagabee for a snack. She has a very blunt and cool personality. Her silence is less about being "cool" and more about being socially awkward. However, she seems to be the type who is friendly toward other girls. While she may seem like a typical "cool beauty" character at first glance, she also has a playful side. She has clear, white skin and black bobbed hair, with a beauty mark below the left side of her mouth. She usually wears clear silver-rimmed glasses, giving off an intellectual and calm atmosphere. Tanaka Ryunosuke's girlfriend. (Tanaka confessed and Shimizu accepted.) Calls Tanaka Saeko "Saeko-san." Calls Tsukishima Akiteru "Akiteru-san."
