Description
Kī Saegusa is a vibrant student at Dream Academy, excelling as both an idol and producer. Her striking appearance features bright blonde hair styled in voluminous twintails secured by green ribbons, cerulean eyes, and red glasses worn offstage. Radiating energy and cheer, she often repeats her signature phrase, “Ok-ok-okay!”, a habit inspired by her mother, a doctor who helped her overcome childhood shyness through a metaphorical “spell” that ignited her self-confidence. This transformation led Kī to embrace her love for cuteness and pursue idolhood, eventually enrolling at Dream Academy.

As Seira Otoshiro’s producer, Kī skillfully balances guiding Seira’s debut with her own performances. Her journey from a reserved, friendless child to a determined idol underscores her character growth. She represents the Magical Toy brand, embodying its playful aesthetic with an idol aura featuring a toy alicorn adorned in pearls and bubbles filled with stars or whimsical objects. Notably, she debuted without Magical Toy’s basic coord and remains the academy’s sole idol lacking a Premium Rare dress. Her singing voice is shared with Kaede Ichinose, later expanding to characters like Ran Shibuki and Shion Kamiya.

Key achievements include winning the Pon Pon Crepes image girl audition with Seira’s encouragement and participating in events such as a first-love-themed fashion show and a concert rivalry against Starlight Academy. Demonstrating strategic prowess, she formed units to counter Mizuki’s group, highlighting her dedication to peer support.

Her preferences include Brain Thunder drinks and Pon Pon Crepes, while spicy curry remains a dislike. A Sagittarius, her Unicorn Sagittarius Coord reflects her zodiac. She is the third glasses-wearing idol and the sole main character unaffiliated with an official unit, never performing alongside Mizuki. Past details include attending Aikatsu! Boot Camp and childhood sessions naming accessories with her mother—a practice later replaced by numerical labels.

Her name, “Saegusa,” combines “sae” (skillful, nodding to her producer talents) and “gusa” (grass), while “Kī” references Kī province or actress Kī Kitano. Across her arc, she navigates dual roles with a blend of exuberance and calculated precision, embodying both infectious enthusiasm and meticulous planning.
