Ayumu Murase Hinata Shoyo: An endlessly bright, energetic, and loud sun-like boy. Murase: A super-intellectual sharp-tongue. Highly knowledgeable and articulate, he ruthlessly shuts down and roasts co-stars on the radio with razor-sharp wit. Loud. Kaito Ishikawa Kageyama: A clumsy, simple-minded genius setter who is a total klutz at anything other than volleyball. Ishikawa: A super-talkative, cheerful otaku. On the radio, he's the beloved target who is completely played and teased by Murase (Hinata's VA). Loud. Koki Uchiyama Tsukishima Kei: A cynical, twisted, and sharp-tongued person who always keeps his distance. Uchiyama: Real-life Tsukishima. His energy is always flat; he's known for his consistent "salty" attitude, frequently saying things like "this is a pain" or "I want to go home" on the radio, but he actually observes his surroundings well. Loud. Soma Saito Yamaguchi Tadashi: A modest, kind-hearted boy who devotedly follows behind Tsukishima. Saito: A calculated, intellectual sharp-tongue. He loves literature and has soft manners, but he's a bundle of contrasts who will drop a sharp roast or poison with a smile on the radio. Loves Tsukishima. Loud.

Yuki Kaji Kozume Kenma: Shy, lethargic, hates standing out, and loves games; the "brain" of Nekoma. Kaji: A super-energetic, extroverted hot-blood. Extremely professional, he's the type to talk a lot and liven up the conversation. Loud. Yuichi Nakamura Kuroo Tetsuro: A provocative master of the unreadable smile, yet a dependable captain who looks after others. Nakamura: Real-life Kuroo. His sharp speech, thorny teasing, and the persuasive power of his low voice are exactly like Kuroo. Loud.

Daisuke Namikawa Oikawa Tooru: Usually flirty and elusive, but a cold-blooded genius captain on the court. Namikawa: Loved by everyone and teased by all. Though a legendary senior in the VA world, he's a bit of a klutz, so juniors (like Murase) tease him with casual speech. He has zero of Oikawa's "perfect" aura and is a peak approachable, beloved character. Loud. Hiroyuki Yoshino Iwaizumi Hajime: The manly, stoic ace of Seijoh who punches Oikawa and calls him "Trashy-kawa." Yoshino: A dependable "big brother" type with adult composure. His talk is incredibly sharp, and he completely controls the room at radios and events. His merciless roasts of Namikawa and their perfect chemistry make him the "Real-life Iwa-chan." Loud. Atsushi Tamaru Kunimi Akira: Always energy-saving, hates unnecessary movement, and is a calm, collected indoor type. Tamaru: A refreshing, sharp-tongued, older-brother-style sadist. A polite young man with soft manners and a sweet voice, but on the radio, he casually drops lethal roasts on Namikawa or Furukawa while smiling. Loud. The gap is huge. Loud.

Mamoru Miyano Miya Atsumu: The number one high school setter. Confident, cheeky, and a handsome guy who uses a thorny Kansai dialect. Miyano: A walking variety show, loudness levels breaking through the limit. He makes the surrounding cast tired from laughing. Hideaki Kabumoto, who plays Atsumu's twin brother Osamu, is the level-headed straight man. Loud. Nobunaga Shimazaki Suna Rintaro: Always listless. Close with the twins. Shimazaki: A volleyball otaku with maxed-out energy. A super high-tension man. Loud.

Ryohei Kimura Bokuto Kotaro: A top 5 national ace. An extreme extrovert whose moods swing wildly, has a youngest-child personality, and is just plain loud. Kimura: A super-sharp older brother type who controls the room perfectly. He lacks Bokuto's reckless, idiotic traits and is a dependable mentor who kindly supports his juniors. Loud. Ryota Osaka Akaashi Keiji: A calm, logical second-year setter who perfectly controls Bokuto. Osaka: A lovable, teaseable character who panics easily. Loud.

Ryota Takeuchi Ushijima Wakatoshi: Possesses overwhelming skill and majesty. A super-stoic captain who doesn't waste words and pierces others with cold logic. Takeuchi: An ultra-polite, pure, and incredibly kind older man. A gentle soul who is always smiling. He likes to goof around. Subaru Kimura Tendo Satori: Loves breaking the opponent's spirit. A quirky player who sings eerie songs and provocatively taunts others. Kimura: A genius at brightening the room. Just a polite party animal. Makes everyone burst into laughter. Loud.

Natsuki Hanae Hoshiumi Korai: Small like Hinata. A sore loser, confident, and a loud attention-seeker. Hanae: Usually has a very calm and smart demeanor. Actually quite loud. Yu Miyazaki Hirugami Sachiro: A calm, collected genius of blocking who never gets heated. Miyazaki: A super high-tension, lovable goofball. He doesn't have a single millimeter of Hirugami's cool atmosphere.
