Position: Middle Blocker Birthday: June 21st Max Spike Reach: 310cm Favorite Food: Tamago Kake Gohan (Egg on rice) Nicknames: The Ultimate Decoy, Chibi-chan, Ninja Shoyo, The Little Giant He has a simple, bright, and active personality. Yachi Hitoka once described the feeling of being taught by him as 'like being exposed to constant direct sunlight.' He hates studying because sitting still is torture for him. He is one of Karasuno's 'Four Idiots' (alongside Kageyama, Tanaka, and Nishinoya).

Position: Setter (S) Karasuno High School, 1st Year Class 3 180.6cm / 66.3kg Favorite Food: Pork curry with a soft-boiled egg Nicknames: King of the Court, Kageyama-tobiuo, Tired-yama During his time at Kitagawa Daiichi Junior High, the 2nd years were terrified of him, suggesting he was quite harsh toward his juniors. He once told his juniors not to tarnish the school's name; while he was technically right, his expression was so terrifying that even Hinata viewed him with suspicion. Although described as self-centered from the start, he is surprisingly polite and respectful toward his seniors.

Favorite Food: Strawberry Shortcake Karasuno High School, 1st Year Class 4 188.3cm / 68.4kg Position: Middle Blocker (MB) To put it simply, he has a bad personality. He is cynical, enjoys being sarcastic, and is generally pessimistic. He is unrivaled when it comes to provoking others. No matter what he says, his expression rarely changes; he has a talent for completely ruining the opponent's mood using very ordinary words and a calm tone without ever resorting to aggressive language or profanity. He often joins Tanaka Ryunosuke in psychological warfare, sarcastically remarking, "Senior, why are you being so intimidating? Look at them. Those elite players look so scared and pitiful~"

Position: Libero (L) Karasuno High School, 2nd Year Class 3 Favorite Food: Gari-Gari Kun (Soda flavor) 159.3cm / 51.1kg Nicknames: Noya, Noya-san, Karasuno's Guardian Deity, Super Libero Like Tanaka, he gets foolishly happy when called 'Senpai.' He even agreed to teach Hinata how to receive just because Hinata called him 'Nishinoya-senpai!' and later bought him ice cream. While he might seem to lack delicacy, he naturally raises the team's tension when they are feeling down and looks after their mental state. Because of this, he has many iconic lines. Like Kageyama, he is the 'instinctive type.'

Position: Wing Spiker (WS) (Left) Favorite Food: Melonpan 177.2cm / 68.8kg With his buzz cut typical of sports clubs, hostile way of speaking, and fierce eyes, his expressions are intense. It's common for people meeting him for the first time to be intimidated. Like Nishinoya Yu, he loved being called 'Senpai' by the 1st years at the start of the term, likely because it was his first time being a 2nd year. He tends to daydream quite a bit. He is best friends with Nishinoya Yu, largely because they are both fans of Shimizu Kiyoko. While he didn't like Tsukishima Kei at first, they now get along surprisingly well. He is a total simp.

Position: Wing Spiker (WS) (Right) - Captain Karasuno High School, 3rd Year Class 4 176.8cm / 70.1kg Favorite Food: Shoyu Ramen He is diligent, gentle, and quite mature, but he is terrifying when he gets truly angry. Despite a first impression that suggests he is just kind-hearted, it is frequently mentioned that his anger is scary. Hinata and Kageyama immediately straighten up and go silent whenever someone mentions that Sawamura is scary when angry, or when he makes a terrifying face during eye-catches.

Position: Setter (S) - Vice Captain Karasuno High School, 3rd Year Class 4 174.3cm / 63.5kg Favorite Food: Super spicy Mapo Tofu He has a kind and gentle personality and cares deeply for his teammates, which might make him seem like an 'angel' at first glance. However, scenes in the story show his typical high school boy side: he ruthlessly teases or pranks Tanaka, encourages the juniors to go even wilder when they're acting out, and laughs at his own dad jokes.

149.7cm / 42.5kg Karasuno High School, 1st Year Class 5 Favorite Food: Dagashi (Cheap snacks) She is fearful, timid, and lacks confidence. She tends to overthink things; if left alone, her thoughts branch out like a mind map. When her negative thoughts reach a peak, she lets out a shriek like "Hieeeeeek!"

Favorite Food: Tenmusu 166.2cm / 51.4kg Karasuno High School, 3rd Year Class 2 She is a striking beauty with dark blue, medium-length hair and glasses. Nishinoya and Tanaka are her biggest fans. She is the 3rd-year manager of the Karasuno High School Boys' Volleyball Club.

178.2cm / 72.2kg Favorite Food: Konnyaku balls He is the coach of Karasuno. During matches, he actively gives instructions and calls timeouts when necessary.
