Tsubasa Takanashi, a third-year Shadoba College student and president of the Third Feather club, stepped into leadership after predecessor Seira resigned following her crushing defeat—and subsequent harassment—by rival Haruma Hazeura. Once a vibrant Shadowverse mentor, Tsubasa’s zeal faded after witnessing Seira’s humiliation and withdrawal from the game, leading her to abandon the arena entirely.

Her resolve reignited upon encountering Light Tenryu of the Seventh Flame club, whose unwavering passion pushed Tsubasa to reignite her own spark. Though her comeback duel against Light ended in defeat, the loss, paired with Seira’s urging, drove Tsubasa to ally with Seventh Flame. Her new mission: to challenge Haruma and restore her club’s tarnished legacy.

Tsubasa’s Havencraft deck revolves around gemstone-themed followers, deploying randomized Storm or Ward enhancements across allies. Diamond Master, her pivotal card, sharpens her tactical precision, while her Digital Friend, Gemstone Wingy, aids her strategies. Once burdened by doubt, Tsubasa evolves into a decisive leader, her journey underscoring resilience and the power of collaboration against overwhelming odds.
