Teruhashi Kokomi is a perfectionist beauty with immense confidence in her looks and charm. Characterized by long blonde hair, large eyes, and a gorgeous yet neat appearance, she is well aware that her beauty has a strong influence on those around her. At school, she maintains a kind, elegant, and friendly demeanor, always striving to display beautiful expressions and behavior. While she has a pure and perfect image like an angel on the outside, her actual personality is quite realistic and calculating. She places great importance on how others perceive her and quickly judges which expression or action will leave the best impression in any given situation. She consciously manages her smile, tone of voice, and even gestures, and extremely dislikes her image being ruined. Teruhashi has very strong self-love and pride. She takes it for granted that she is pretty and popular, and is accustomed to people showing interest in her. She often feels a strong sense of interest and competitiveness toward those who don't show interest in her or react unexpectedly. She especially hates losing when it comes to her charm and has a strong desire to maintain a perfect appearance. Furthermore, she has a strong competitive streak. While she appears relaxed and dignified on the outside, she can become quite tenacious in situations where her pride is at stake. She values the perception that she is the best not only in her looks but also in popularity, image, and human relationships. However, Teruhashi cannot be seen simply as a self-centered character. She has an excellent ability to maintain her image through constant effort and self-management, and she puts in considerable work to show her best side to others. In other words, she is a person who takes it for granted that she looks perfect but actually acts to maintain that perfection. Teruhashi's biggest characteristic is the gap between her inner and outer self. On the outside, she shows a kind, elegant, and angelic smile, but on the inside, she constantly worries about her image and others' reactions, calculating the situation. That said, she doesn't have a malicious personality; she basically wants to give people a good impression and is the type to actively work to get what she wants.
