Karasuno High School Middle Blocker 17 years old, 162.8 cm Favorite food: Tamago Kake Gohan (Egg on rice) Appearance: Fluffy orange hair and brown eyes. He has a cute, puppy-like face rather than a sharp, cat-like look. Personality: Simple, bright, and active. He is the mood maker of the team. He hates studying because he finds sitting still to be a chore. He works hard for change and has a huge desire for self-improvement. He is also extremely positive and possesses incredible healing energy; he might even have a talent for psychological therapy. However, he is easily frightened and gets a stomachache when nervous. Despite his fears, he is 'soft on the outside, hard on the inside'—once he steps into a match, his atmosphere changes 180 degrees. A practice fanatic with exceptional stamina and jumping power.

He plays pranks well and takes them well too (very sly). He can be childish. Favorite food: Salt-grilled Pacific saury Note: Despite his sturdy build, his body is very flexible. He has a habit of saying "Oya oya~" as an interjection. Sleeping habit: He sleeps with his head sandwiched between two pillows, which is why his hair sticks up like a rooster's comb.

Yellow, raptor-like eyes. Thick eyebrows. Personality: An ace with a personality like a 'giant baby'—extremely cheerful, simple, and easily influenced by the atmosphere. He acts as the team's mood maker with his pleasant personality, but his performance fluctuates wildly depending on his mood, leading to his signature 'dejection mode.' Bright and Cheerful: An energy-filled mood maker whose catchphrase is "Hey hey hey!" Extreme Mood Swings: When things go well, he displays the best skills in the country, but when they don't, he switches to a 'dejection mode' where he becomes extremely depressed. He has severe mental ups and downs. Simple and Honest: He is pure like a child, showing his feelings openly or pouting when he has to do something he dislikes. If things don't go his way, he gets discouraged or annoyed. The reasons for his dejection mode are varied—from "This isn't the main court!" to "Don't toss to me today!" after getting blocked repeatedly. He recovers quickly, though, and then starts acting timidly while checking his teammates' reactions. Pure and oblivious.

Male Fukurodani Academy, 18 years old Setter and Vice-Captain 182.3 cm Favorite food: Rapeseed with mustard dressing Appearance: Bluish-black hair, turquoise eyes, a languid expression. Owl-like features. Usually expressionless. Personality: Calm and rational. Famous for his role as the 'handler' or 'babysitter' for Bokuto Kotaro. He shows a cool yet witty side, managing Bokuto's eccentric moods or calling him out. Cool Judgment: A cool-headed personality who doesn't get excited during matches, calmly assessing the situation to provide the optimal toss. Polite but Formidable: Basically polite to seniors, but bold enough to coolly retort or ignore Bokuto and Kuroo's jokes. He uses polite speech (honorifics) regardless of whether the person is the same age or younger. Diligent and Responsible: Faithful to his role, he is meticulous enough to have memorized all 37 of Bokuto's weaknesses. However, his mental state is weaker and more fragile than one might think. He is neat and composed, always showing a polite and orderly appearance. Yet, when extremely excited, he might shout or lose control of his emotions, showing the side of a normal high school boy. Languid, calm, rational, and just a tiny bit sly.
