Yuzuki Seo (瀬尾結月 Seo Yuzuki) is Chiyo Sakura's friend. She is popular amongst their classmates, and is often asked for help on various extracurricular activities. However, her brash personality often makes people feel offended.

She has an older brother Ryosuke, who is a university student.


Seo has shoulder length wavy greenish-blonde hair that is swept to the side in a ponytail and secured by a brown scrunchie, in a loose ponytail. She is of average height, has an ample bust, and her eyes are brown with a slight reddish tint, appearing amber.

Her clothes consist of the standard uniform - a white blouse tucked into a navy blue skirt. Her neck bow is red, as assigned to second year students, and she wears a blazer on top. She wears her uniform in a much more sloppy fashion compared to Sakura. Her bow is the correct colour for her year, but her skirt is shorter, and she wears no socks.

However, when it comes to choir competitions, she wears her hair down and part of her hair is plaited. She is described as high-class and proper. She also wears socks in this case.

Seo is someone who easily offends people. She is not aware of this though. Because of that, Umetarou Nozaki calls her "oblivious". Seo demonstrates this obliviousness fully as shown in episode 10, while watching the movie, where she paid attention only to the alien on screen and failed to notice anything else, even the plot. She also likes to pester Hirotaka Wakamatsu, but that is probably born out of poorly displayed affection.


Seo is shown to have no sportsmanship whatsoever in a comical way. When playing basketball, she would flout all the rules and annoy the other players by hogging the ball and laughing maniacally. However, it is also through this that the basketball team realizes the importance of teamwork and hence appreciate their team more. Thus, Seo's participation in their games not only allows the basketball team to practice for when they meet an annoying opponent, but also brings out the best in the team.

It is shown in the manga, that she does get flustered and embarrassed when she is complimented or confessed to.

Main Article: Yuzuki Seo/Plot


Hirotaka WakamatsuEdit

Seo movie

He doesn't even know that Yuzuki Seo is Lorelei-san, although he is practically in love with her because her music has the ability to help him sleep (he suffers from insomnia; however, after talking to him, Nozaki feels that Seo is the reason for his lack of sleep, but he doesn't point this out to him). Nevertheless, they continue to go on different kinds of outings. When Seo suggested she would take someone else, Wakamatsu responded that that would upset him, and he prefers to go with her anywhere she likes. No matter how crazy she acts, he continues to follow her around, trying to find out what anyone can like about a girl like her. There are some hints about him having romantic feelings for her.

Ironically, she behaves quite normally with Sakura, and they are good friends. They sit next to each other in class; that's why they became friends.
