Akane Yamamoto, younger sister of Nekoma High’s ace Taketora Yamamoto, channels her fervent passion into unwavering support for the school’s volleyball team. At 13, her petite 144.3 cm frame and 35.4 kg build are accentuated by fluffy orange twin tails, a cat-shaped hairpin securing her bangs, and a scrunchie adorning her left wrist, often paired with a crisp black sailor uniform. A second-year Nekoma Junior High student, she later advances to Nekoma High and university, interning at a publisher while retaining her volleyball devotion. Her sharp tactical insight transforms her into an unofficial match commentator, dissecting strategies and player choices with precision, often guiding Alisa Haiba through the sport’s nuances. Dubbed the "Nekoma Engine," her dynamic cheers and play analyses—even of rival teams—ignite the squad’s morale. Yet her intensity occasionally sparks social friction, as peers misinterpret her fervor, once mistaking her admiration for Lev Haiba’s raw athleticism and potential as romantic interest. Privately, she grapples with fears of being seen as overly obsessive, masking vulnerability beneath her confident volleyball discourse. Pride in her brother’s achievements simmers beneath a shy reluctance to voice it openly. Her bond with Taketora contrasts her candid exchanges with Lev, where she balances blunt critiques of his technique with enthusiastic praise for his game-changing capabilities. As she transitions from a junior high spectator to a pivotal cheerleader during Nekoma’s matches, her unofficial leadership fills the void left by absent managers. Post-graduation, her path leads to academia and a publishing internship, her volleyball legacy enduring even as spin-offs and films leave her future endeavors open-ended.
