Kouhai is a sweet, hardworking junior member of Sales Division Two who's caught plenty of attention around the office thanks to her youth and looks. She's almost always seen hanging around her senpai though, so coworkers have pretty much decided they're already dating—a rumor that only gets worse as the series goes on. They start spending less time at work and more time at his apartment, which does absolutely nothing to stop people from assuming they're sleeping together. Even her friend Rikei is convinced, though both Kouhai and Sempai keep denying it.
Outside of work drama, Rikei regularly drags her into cosplay at Comiket. She's suited up as Tifa from Final Fantasy and Mai Shiranui from Fatal Fury, among others.
She shares an apartment complex with Maegami-chan and Gimai-chan. In a crossover with Douki-chan, the two bond over drinks and end up being each other's cheerleaders in their respective romantic pursuits.
