Keke Tang, a third-year student at Yuigaoka Girls' High School and founding member of the idol group Liella!, channels her bubbly optimism and relentless drive into every endeavor. Born in Shanghai, she relocated to Japan, driven by her admiration for the school idol group Sunny Passion and a desire to connect with her Japanese heritage through her mother’s roots. Her mantra, "there is no time like the present," fuels her proactive approach to life and leadership within Liella!.

A self-proclaimed fashion enthusiast, Keke combines creativity with practicality as the group’s wardrobe supervisor, designing and refurbishing costumes with meticulous care. Though her energy seems boundless, she discreetly evades gym class due to limited stamina, relying instead on sugary pick-me-ups—especially ice cream—to combat stress, a practice inherited from her mother. Fluent in Japanese with JLPT N1 certification, her speech carries a distinct Shanghainese lilt, often depicted in written media through katakana inflections.

Family ties deepen her narrative: her older sister, Mengmeng Tang, emerges in later seasons as a steadfast supporter, urging Keke to chase her dreams despite uncertainties. A subtle yet pivotal detail—the adjustment of her birthday from July 7 to July 17—acknowledges historical sensitivities tied to the Second Sino-Japanese War.

Keke thrives as Liella!’s spirited glue, mediating conflicts and rallying members with infectious zeal. Her initial friction with the reserved Sumire Heanna evolves into a spirited camaraderie, blending rivalry and mutual growth. As graduation looms, Keke confronts her future, inspired by her sister’s encouragement to intertwine her passions with her career path. This resolve propels Liella! toward their final Love Live! challenge, striving for back-to-back victories while mentoring a new generation of members, ensuring their legacy burns bright beyond her tenure.
