Dina Pan functions as the younger twin in the idol-racing duo Hell's Kitchen alongside her sister Pan Ziyu, both attending CS Production School. Her appearance includes plum-colored hair styled symmetrically with front strands near her ears and hair buns held by scrunchies, complemented by amber-yellow eyes. Casual attire features a bright pink schoolgirl-style top with white sleeves, a light lilac collar, and a plaid tie, paired with a plum skirt sporting green suspenders and lilac-blue thigh-high stockings with gold buttons. A blue panda brooch accents her collar, and she wears a bangle on her wrist. Her racing and idol costume is a unified black-and-gold Mandarin-style dress featuring a heart-shaped chest cutout, exposed midriff, purple bows, and matching boots, accessorized with purple panda ears and a panda-head armband.

Her personality presents a stark contrast: a vibrant on-stage idol persona versus an off-stage demeanor defined by arrogance and selfishness. This manifests when she and Ziyu pressure the racing association to reassign Rin and Misa's time slot, later taunting them about their prior victory being beginner's luck. Her background involves participating in both cooking/sweets-themed idol activities and jet racing under the Hell's Kitchen banner.

Her character development unfolds primarily through the game narrative. Initially, Dina and Ziyu plot to win the Kandagawa Cup to retire from idol work and focus exclusively on racing. However, receiving acknowledgment from fellow racers about their unique ability to balance both careers leads them to abandon retirement and commit to continuing as idols. While retaining elements of pride, this growth includes mentoring other teams—such as advising Sea Serpents to incorporate shrine maiden duties into performances and critiquing Dress's comedy routines. The twins also participate in races wagering autographs or backstage passes.

Relationships focus on her dynamic with twin Ziyu, characterized by shared ideals, mutual flaws of arrogance, and an equal partnership in racing and performances. Antagonistic interactions occur with Rin Namiki and Misa Aoi after Hell's Kitchen displaces them from a race slot, though subsequent races foster a sense of competitive respect.
