DescriptionThe lead character designer of Eagle Jump; she was the character designer for the game that inspired Aoba to become one herself. Though she has a laidback attitude, she is quite stern and a bit of perfectionist: Kou quite often works overnight to complete her work and sleeps at the office. She gets easily drunk and is also Rin's close friend. | |
