Shogo Narumi (鳴海 彰伍, Narumi Shogō ?)
Voiced by: Tomokazu Seki[1] (Drama CD)
The vain, handsome, and temperamental main hair stylist of the Scissor Project. Although he is fiercely competitive in comparison to the majority of the other characters, he is the most amenable member of his own family. He is extremely hot-tempered, especially towards Kiri, but does have a sweet side which he rarely shows. He aims to be the top hair-stylist in Japan and has won every national hairstyling competition of seven years. The only time he has ever lost a competition is ten years ago, when he was defeated by a mysterious little girl 'Number 17'. It later transpires that the girl was in fact Kiri. Though this initially damages their already rocky relationship, Narumi later seems to develop feelings for her, having romantic dreams about her and even accidentally kissing her at the end of volume 8, much to Ochiai and Chisami's annoyance. He even stayed with Kiri to comfort her and watch over the house in volume 9. He is extremely popular with girls and they constantly clamor for his attention but he doesn't appear to be interested

Kei Minami (南 啓, Minami Kei?)
Voiced by: Hiro Shimono[1] (Drama CD)
The member of the Scissors Project that does nail art. Kei is playful and is often seen eating junk food and candy. Kei likes to come up with nicknames for his friends like 'Naru-Naru' and 'Narurin' for Narumi while he calls Ochiai 'Occhi'. He also serves as emcee for any Scissors Project event, announcing the model and occasionally commenting while Narumi cuts. He hardly ever wears his school uniform and often wears a visor sideways on his head. It is later shown that Kei is not good at spelling, he got a "5%" on his spelling test. This is why, one time, a Scissor Project's project on one girl failed, because he spelled Komasu incorrectly. Kei is actually very mysterious and he doesn't reveal much about himself.

Kazuhiko Ochiai (落合 計彦, Ochiai Kazuhiko?)
Voiced by: Aoki Makoto[1] (Drama CD)
The overall beauty consultant of the group. He is the brains behind the operation and acts like a human computer, with "data" on every girl in the school. He's at the top of his class. He also used to have a rather "old-man" hairstyle until he meets Narumi who then gives Ochiai his current Hairstyle. Ochiai loves to mess with Narumi and is often scheming. Later on in the story it seems that he develops a crush on Kiri. He chases after her and even has Kiri's picture as his cell phone's wallpaper. When he was in middle school, his parents owned a company called Alix Cosmetic Corporation that was, in his opinion, "doing well, even though it was not a well-known enterprise." He has an older sister and younger brother, and all his family members wear glasses, even his bird.

Seiji used to be an idol among hairstylists in his generation and he always defeated Shogo Narumi's father in competitions, but had left the spotlight once he had gotten married. Kiri looked up to her father when she was younger and she wanted to cut hair like him, so Kiri gained the speed cutting skills from her dad. He also wishes for Kiri to become a beautician like him.

Kiri's mother is a famous special effects make-up artist in Hollywood. Even after years of being so far apart, Emi and Seiji's marriage has never been strained and the two keep in touch through email.

Chisami Narumi (鳴海 千佐美, Narumi Chisami?)
Shogo's cute little sister, who Kiri indifferently "saves" one day when her hair was tangled in a bush. Because of this, Chisami seems to think that Kiri is her "Prince Charming" (as she had thought Kiri was a boy). She later finds out that Kiri is a girl, but she still admires her and refers to her as "Prince-sama".
