Kaya Takagi (née Miyoshi, born June 25, 1993 in Saitama-ken, Japan), is Miho Mashiro's best friend and Akito Takagi's wife. She sees Azuki, Takagi, and Mashiro pursuing their dreams, so she decides to have a dream too. Her first dream was to be a writer, but then decided later on that she wanted to make Takagi, Mashiro and Azuki's dreams to come true. In order to do so, she at least helps the mangaka pair by being their assistant.
