Teruhashi Kokomi

"Life is in very easy mode. This is all because I am gorgeous."

- talking about herself, Chapter 13

Kokomi Teruhashi (照橋心美, てるはし ここみ lit. Teruhashi Kokomi) is one of the main characters of the series. She is a student in Saiki Kusuo's class and she is considered very attractive by both women and men, who often stop and stare upon seeing her. She was played by Hashimoto Kanna in the live action film of the series.

Appearance
Kokomi is a girl who has exceptionally good looks which she admits herself, correcting that she isn't being overconfident about it but simply telling the truth. She has a lean body with long, flowing blue hair that reaches just past her shoulder and blue eyes. She is mostly seen with her hair untied and occasionally wears dresses and skirts whenever she goes out of town. In school, she wears the PK uniform that a standard female student wears, a long-sleeved shirt with a ribbon on her chest, and she wears a short green skirt with tight black stockings on her long legs. The skirt is quite short, so the majority of her thighs and legs are revealed.

Personality
When Kokomi was first introduced, she proclaims herself as beautiful and nice, the epitome of a perfect, pretty girl. Even though her appearance is attractive, her politeness is a charade.

In truth she is very conceited and a gold digger. She is a smooth talker, making her able to manipulate and persuade nearly everyone with her beauty and easily gets away from others with just simple excuses. As the most popular girl in school, she is highly sociable.

Being flirted on and getting extreme reactions is normal for her, therefore when Saiki Kusuo was not startled or star struck by her beauty she was puzzled as to why. With this reasoning, along with her stubbornness and pride, she started to pursue after Kusuo until she fully falls for him.

She is highly competitive in several aspects, such as beauty, sports and academics. An example being when she ordered two ramen for her and Rifuta Imu and, despite the two being hailed as beauty queens, Kokomi was considered above her since she was given a extra-large bowl while Imu was given a normal bowl of ramen. Despite her competitiveness, she is very careful to not harm others' feelings and livelihoods.

She usually hides her true emotions around others with a smile, such as anger and disappointment, to keep her perfect facade. However, sometimes her emotions do come out due to shock and/or embarrassment but is able to go back to her facade. An example being when someone believed Kokomi’s crush was Riki, she is angered and surprised, but then quickly changes the subject of it.

Over the series, she has slowly changed. Her greediness mellowed out, such as she turned down an offer from Saiko Metori of marrying into wealth. She makes genuine friends, accepts Kusuo’s looks and personality unconditionally, slowly resolves to not having to be perfect in front of him and decides on wanting to go and talk to him over several guys that wanted her attention.

Near the end of the series, Kusuo had a great awareness and respect for her effort, even though he still avoids her. She put in extra effort to memorize the names of everyone in the school and their individual quirks to keep up her reputation, having a pretty good insight and adaptability. She exerted herself too much in trying to memorize everybody's lives that she collapsed in front of everyone.

History
Kokomi was born on August 6th. She was highly cute, enough to make her own doctor blush just by looking at her. Word got out about her, and a huge crowd of people went to go look at her through the nursery window. She meets her older brother, Teruhashi Makoto, and he too gets too infatuated with her.

Time goes on, she grows up, enrolls into PK Academy and ends up in the same class as Saiki Kusuo. Kusuo introduces her to the reader during his monologue about him not understanding the concept of love. He says she is the most popular girl but has no interest in her, due to her thoughts of the other classmates being poor brats and unable to see her beauty.

On August 6th, her birthday, she is walking around aimlessly. Several men approach her and she nicely rejects their flirting advances, a normal for her. She notices Kusuo across the street, recognizing him from her class. She admits that she nearly forgot about him due to him being very quiet in school. She goes on to incorrectly remembering his first name, believing it is Kunio. Feeling sorry, believing he is having a dull summer vacation, she decides to go and talk to him. She greets him, he only politely bows and leaves. Dumbfounded by Kusuo's brief and unfazed reaction, she starts on trying to get his attention, believing he is thinking about her being an illusion. However, no matter what she tried, Kusuo continued to ignore her. When Kusuo suddenly disappeared in front of her, she thought that Kusuo might be an illusion. Remembering her own words from before, she concluded that she was the one hallucinating about Kusuo and believed that she had fallen in love with him.

Since that day, Kokomi always finds it irritating that Kusuo blatantly ignores her and has sworn to herself that she will end up making him say "offu" to her.
