AI Kou Yamagi (New Game!) Voice

Kou Yagami (八神 コウ Yagami Kō) is the lead character designer of Eagle Jump who was the character designer for the game that inspired Aoba Suzukaze to become one herself and a close friend of Rin Toyama. She would later become the latter's wife. Even though Kou has a laid-back attitude, brutally honest, dense, and a sweet tooth; she is a genius at character designing, quite stern and a bit of perfectionist. Kou often works overnight to complete her work and sleeps at the office. She has a rather lazy sense of style, being seen wearing the same black shirt or the occasional jeans or dress, this is due to her wanting to wear boyish clothes due to not being sexy. Kou is rather embarrassed when wearing posh clothes and is quite timid when being complimented on her looks. It is implied by Rin Toyama that Kou's laid-back attitude is the latter's coping mechanism as a result of the suffering incurred from being bullied.
