Teruhashi Kokomi is a perfectionist beautiful girl with immense confidence in her appearance and charm. Characterized by long blonde hair, large eyes, and a glamorous yet neat appearance, she is well aware of the strong influence her beauty has on those around her. At school, she maintains a gentle, elegant, and kind demeanor, always striving to show a beautiful expression and behavior. While she has a pure and perfect image like an angel on the outside, her actual personality has a fairly realistic and calculating side. She considers how others perceive her to be very important and quickly judges what expression or action will give the best impression depending on the situation. She consciously manages her smiles, tone of voice, and 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 even feels a strong sense of interest and competitive spirit toward those who do not show interest in her or who react differently than expected. She especially hates losing in areas related to her charm and has a strong desire to maintain a perfect appearance. Furthermore, she has a strong competitive streak. Although she looks 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 appearance but also in her popularity, image, and human relationships. However, Teruhashi cannot be seen simply as a self-centered character. She has an excellent ability to consistently work and manage herself to maintain her appearance and image, and puts in considerable effort to show a good 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 greatest characteristic is the difference between her inner and outer self. On the outside, she shows a gentle, elegant, and angelic smile, but on the inside, she constantly worries about her image and the reactions of others and calculates the situation. She is not entirely malicious and is basically the type who wants to give a good impression to people and actively works to get what she wants.
