Kouhai

She is Douki-chan's junior colleague, who also harbors feelings for the male protagonist. Unlike Douki-chan, she is more direct & confident in her approach, including using her well-endowed "assets" to attract him. Sometimes she cosplays in various outfits & characters to seduce him. She is very playful & clingy to her senpai/crush, to the dismay of Douki-chan. While mostly friendly with Douki-chan, her hidden yandere side will pop up if she sees Douki-chan getting her own moment with the male protagonist.
