Shima Nishina

A masculine-looking girl that joins Kae's gang later in the series. She's the descendant of a rich family, and is talented in both sports and arts (she even has her own doujin circle), and is considered the main threat for the rest of Kae's suitors.

She takes Kae's first kiss.

It is revealed that Nishina met Kae before her transformation, in the early stages of her debut as a doujin artist at Comiket, and with Kae's encouragement, had gained the motivation and confidence to pursue drawing. Grateful for her support, she has been searching for her ever since, but didn't recognized her until later, as Kae had considerably changed in terms of physical appearance.
