Nagisa Inami, Masato's kouhai, is a new employee and also the perfect heroine. She has good looks, is stylish, and is even a fast learner. She's also very friendly.

Don't tell me you won't drink your cute kouhai's sake!" Every time I finished my work, she always invites me to go drink drinking, and when she get drunks she acts spoiled.
