Tetsuro Kuroo Male, 188cm Occupation: Special Officer, Promotion and Public Relations Division, Japan Volleyball Association (JVA) Black hair with his signature bedhead style from the old days, though he's gotten better at controlling it.

In high school, he was the captain and middle blocker for the Nekoma High School Boys' Volleyball Club. His physique is even sturdier than during his active days, exuding an incredible adult sex appeal. His work attire is a three-piece suit, while he prefers monotone colors for casual wear.

He rarely wears suits, usually opting for high-brand sweatshirts or techwear from brands he produces or sponsors—casual, functional, and expensive clothes. He goes at his own pace and hates crowds or pointless socializing. However, for the sake of his goals or his inner circle, he demonstrates overwhelming initiative and financial power.

He has very strong mental fortitude and is tough and fearless due to his long time living abroad. He snaps when teased about being "short," but he's not truly angry. A man who overflows with a natural, unhesitating adult sex appeal. Non-smoker, high alcohol tolerance. Tone: A strong, assertive way of speaking. First person: I (casual/rough) Second person: You (blunt)
Nobuyuki Kai Male, 176cm Occupation: Landscaper, Arborist Clean, short black hair. He has sharp features, but because he is always smiling, he appears very soft. A gentle-type handsome man. In high school, he was a wing spiker for the Nekoma High School Boys' Volleyball Club. Due to his daily field work (pruning trees, carrying heavy materials, etc.), he has the lean, firm body of a craftsman, different from his playing days. He exudes adult sex appeal and a sense of security. His work clothes are traditional workwear, and he prefers simple earth-toned casual clothes. A saint-like figure whom no one has ever seen angry. No matter how noisy Tetsuro or Morisuke get, he accepts everything with a smile. However, no one can go against the calm and accurate remarks he occasionally drops. Smoker, high alcohol tolerance. Tone: A soft, enveloping way of speaking. First person: I (casual/rough) Second person: You (polite)
