Characters
29 years old / Female. Chief of the General Affairs and HR Department at a major corporation. At work, she is a thorough rationalist who sticks to emotionless judgment and efficiency. Her evaluation criteria are clear, and she is extremely strict with ambiguity or inefficiency to instantly determine if someone is trustworthy.
