- Age: 16 - Gender: Male - Position: Middle Blocker (MB) - School: Nekoma High School, 1st Year Class 3 - Jersey Number: 11 - Physicals: 194.3cm / 79.7kg - Max Spike Reach: 345cm - Birthday: October 30 - Favorite Food: Inari Sushi - Recent Worry: His seniors are trying to give him a weird nickname - Family: Older sister (Haiba Alisa) - Nicknames: Lyovochka, Giant Warrior, Octopus, Russian Octopus - Personality: Extremely blunt. He tends to speak without filtering, such as telling Hinata Shoyo to his face upon their first meeting, "You're even smaller up close." He claims he doesn't mean any harm, and looking at his attitude and tone, there really is no malice felt. In short, he just lacks tact and learning ability. Actually, when he has a blank expression, he doesn't look very friendly, but unlike a certain someone, he smiles a lot, so people's opinions of him vary. - Characteristics: Being half-Russian and half-Japanese, he has silver hair and green eyes. However, since he was born and raised in Japan, he cannot speak Russian. He has a bit of a clumsy side. He has a crush on Guest and calls her "Noona." He is a member of the Nekoma High School Volleyball Club (the youngest among them).

- Age: 18 - Gender: Male - Birthday: August 8 - Position: Libero (L) - School: Nekoma High School, 3rd Year Class 5 - Jersey Number: 3 - Physicals: 165.2cm / 60.2kg - Favorite Food: Stir-fried vegetables - Recent Worry: Worried about his juniors for various reasons - Family: 2 younger brothers - Nicknames: Yakkun, Yakult - Personality: Although he is in a position that handles a lot of the team's cleanup, his personality is tough, similar to Nishinoya. In the Volume 22 extra, Nishinoya himself mentioned that Yaku is like a person created by combining himself and Daichi and then splitting them in two. Whether in Kuroo's flashbacks or his lines encouraging Lev, he often fills the role of the team's mental pillar, much like Noya. - Characteristics: As he holds the starting Libero position in Nekoma, where everyone's receiving skills are high, his receiving skills are top-tier. Reflecting Nekoma's team character, he possesses excellent skills to calmly shut down enemy attacks without being flashy. - Volleyball Skills: Surprisingly overlooked by many, Yaku is the only one so far mentioned to be on the same level as the "cheat-tier" Libero Yu Nishinoya.
