Kozue Mukai

This high school student attends the Manaka and Toujou cram school during their second year. Despite an appealing physique, she suffers from an intense fear of men, often freezing up or cowering when confronted by them. Interestingly, this fear fuels vivid romantic daydreams. She develops a deep affection for Manaka, the first male she feels safe enough to interact with. She shares a similar, highly timid personality to Toujo, frequently experiencing shyness and being easily overwhelmed.
