– Kī's main catchphrase.

Kī Saegusa (冴草 きい Saegusa Kī) is one of the new main characters introduced in the 2014 series of the Data Carddass Aikatsu! game and the related anime adaption along with Seira Otoshiro.

Like Seira, Kī is one of the main girls representing Dream Academy. She is a pop type idol whose primary brand is Magical Toy.



Kī has bright blonde hair with puffy, balloon-like twintails, each tied with a green ribbon and cerulean eyes. When not performing, she usually wears her red glasses.


As a pop-type idol, Kī is very cheerful and energetic. She has a habit of saying certain words twice or even thrice before ending a phrase or sentence. This is revealed to be an influence from her mother who would do the same. Kī states that her mother is "her producer", having been her main boat of support and confidence in her childhood.


Saegusa (冴草): Sae () means (to be) skillful, possibly referring to her talent as a producer and Gusa ( kusa) means grass.

(きい) doesn't have a specific meaning and could be explained in many ways. It is often associated with Japanese actress Kī Kitano (北乃きい).


Kī first appeared during Seira's debut, telling Seira not to tell Aoi Kiriya her entire background which she ended up telling in the process. During her childhood, Kī was a very shy girl with no friends. She stated that she was jealous of all the other girls in class, because they were cute, and she wasn't. Kī's mother noticed her dilemma and subsequently casted a "spell" on her daughter to give her self-confidence so that she may be cute. Because of this, Kī has been able to grow more confident in herself, and eventually entered Dream Academy where she was introduced to Seira; becoming her producer and later on, an idol.
