Laila April is a 13-year-old girl with vibrant shoulder-length pink hair secured by blue ribbons and warm brown eyes. She wears a crisp blue shirt layered beneath a white and orange jacket, paired with a short white skirt. A pink ribbon adorns one leg, while a yellow deck case straps to the other.

As the protective older sister of Rikuto April, she radiates determination, often shielding him with fierce loyalty. Laila’s meticulous nature drives her to instinctively tidy disorganized spaces, a trait showcased upon entering the cluttered Number One Star Ship for the first time. Her passions include idolizing the daring space pirate Eris and enthusiastically following the performances of pop idol Magical Star Saki.

A novice card battler wielding a Pentan deck, Laila’s strategy centers on her cherished "The Knight Pentan." Though eager, her limited grasp of complex mechanics leads her to depend on Rikuto’s guidance. Committed to growth, she trains under mentor Rei, engages in rigorous battles, and strives to harmonize her meticulous habits with her ambition to master the card-battling arena.
