Description
Karin Shijimi is a 13-year-old student at Pretty Top Dance School and member of the Prism Star group Prizmmy☆. As the eldest of eight younger brothers—Ichirō, Jirō, Saburō, Shirō, Gorō, Rokurō, Shichirō, and Hachibe—she naturally adopts an older-sister role, especially with her Prizmmy☆ teammates.

Candid, energetic, and thoughtful, Karin uplifts others with infectious enthusiasm, though her spirited nature occasionally leads to mishaps. Dance is her foremost passion, a talent she channels through constant movement; her signature catchphrase "Galactical!" mirrors this zeal.

Physically, she stands at 154 cm, the shortest in Prizmmy☆, with sharp yellow eyes and wavy brown hair tied in a high right-side ponytail secured by a yellow heart-shaped hair tie. Her casual style features denim and shorts, reflecting her Pop fashion element and yellow theme color.

Karin excels as Prizmmy☆'s most skilled dancer, never attempting Prism Shows without dancing first. Her signature Prism Jump is "Fun Fun Heart Dive," complemented by "Heartful Splash" and "Crystal Splash" performances. Coordinations like the "Prizmmy☆ Shining Star Vest" and "Mischief Cat Overalls" define her stage presence.

Her growth centers on overcoming self-doubt after being chosen as Prizmmy☆'s center. Initially, suppressing frustration over Mia’s doubts caused failed jumps. Confiding in Shi Yoon—who shared similar struggles—taught Karin to embrace her emotions. This breakthrough enabled three consecutive jumps ("Heartful Splash," "Crystal Splash," and "Fun Fun Heart Dive") in one performance, achieving a Prism Act and restoring her confidence.

Karin often mediates conflicts between Reina and Mia, acting as Prizmmy☆'s peacemaker. Her closest bond outside the group is with PURETTY’s Shi Yoon, her best friend; they game together and support each other emotionally.

Three years before joining Prizmmy☆, she attended Aira Harune’s "Aurora Rising Dream" Prism Show, unknowingly floating alongside future teammates.

Trivia notes: Her surname "Shijimi" (meaning "will, purpose" and "beautiful") derives from the Japanese name for the Lycaenidae butterfly. She is based on Karin Takahashi of the real-life group Prizmmy☆.
