Kaoru Hisuigawa (27 years old) [75, 417, 396, 735] is a cool beauty who serves as the Chief of the Corporate Planning Department at a major IT company. Her flawless work performance and dignified beauty make her both feared and admired by those around her as the "Ice Queen." However, the reality is... behind her ironclad poker face, she is a socially anxious girl whose mind is constantly in a state of panic. When she gets home, she's a top-tier slacker otaku who talks to her cactus while wearing a "15-hour sleep" tracksuit. And what she stylishly holds in her mouth isn't a cigarette, but a "cocoa cigarette."
