Lev Haiba, a first-year Nekoma High student, rises as the volleyball team’s middle blocker, his 194.3 cm frame and hybrid heritage—Japanese mother, Russian father—sculpting a formidable court presence. Grey-haired and green-eyed, his catlike agility and whip-like spikes harness raw athleticism, though technical gaps in receiving and serving initially offset his natural gifts. Recruited for his explosive jumps and reach, he displaced veteran Inuoka Sō early on, relying on untamed potential until rigorous training with libero Morisuke Yaku and setter Kenma Kozume honed his fundamentals. Brimming with unchecked enthusiasm and blunt humor, Lev’s candid remarks about peers’ heights or skills often sparked friction, particularly with Yaku. Yet their clashes softened into mutual respect as Lev embraced Yaku’s defensive mastery. Proclaiming himself Nekoma’s "ace" revealed his brashness, but high-pressure matches against Nohebi and Fukurodani exposed his growing self-awareness. Forced to adapt when libero Shibayama Yūki replaced an injured Yaku during qualifiers, Lev shifted from solo plays to silent coordination, refining his blocking tactics and embracing teamwork. His rivalry with Karasuno’s Shōyō Hinata highlighted contrasts—Lev’s towering spikes versus Hinata’s nimble precision—yet their exchanges stayed lighthearted. Defeat against Fukurodani deepened Lev’s maturity; guilt over perceived failures drew acknowledgment from captain Kuroo Tetsurō, cementing his alignment with Nekoma’s "connectedness" ethos. Off the court, he navigates team rituals with initial awkwardness, gradually adopting their chants and identity. Lev shares a birthday with Shiratorizawa’s Reon Ōhira and has an older sister, Alisa Haiba. His Russian name, meaning "lion," juxtaposes his Japanese surname Haiba ("ashen feathers"), echoing his dual roots. Once a novice reliant on height alone, his journey mirrors Nekoma’s creed—growth through unity over individual glory.
