Sayori

Sayori is initially portrayed as the character archetype of a Genki Girl, expressing a bubbly and cheery disposition. She is very clumsy, noted for finding ways to accidentally hurt herself or to drop random things. Regardless, she is shown to be a jokingly cunning individual who can trick others to get food, shown after managing to eat Natsuki's cookie without her permission. Sayori has also been known by the protagonist to obsess over activities that she loses interest in later. She states that writing poetry and studying literature is different to her than those other interests because it helps her explore her feelings. However, it is later revealed that she suffers from bad depression and works so hard to make the people around her happy to cope with her own lack of self-love amongst other things. She is also usually the only character, other than the protagonist, shown to break up arguments, Monika noting that her sentiments are necessary to keep a relaxing atmosphere in the Literature Club. Monika notes that while she may look like a good leader, Sayori is usually better when it comes to dealing with people, notably at mediations. She tries her best to help everyone be happy and dislikes attention directed at her well-being because she feels unworthy of anything that others have to offer her.

Sayori is also introduced as the protagonist's childhood friend. The protagonist seems to view her as an airhead and slightly annoying at the beginning of the game, but he starts to sympathize with her after she confesses about her depression.

Sayori's depression makes her disorganized, and she often cannot find a reason to get out of bed in the morning when she tries to wake up, which is why she is usually late for school. Her room, which the protagonist regularly cleaned for her, is also noted to be untidy. The protagonist notes how there hasn't been much change in her, and the changes the protagonist notices in her later are due to Monika's interference, amplifying her depression and suicidal tendencies.

Sayori has coral pink hair, cut chin-length and slightly curled at the ends, with a large red bow on the upper left side of her head. Like the other female characters, she has two prominent strands of hair beside her bangs, and her eyes are a bright sky blue. She is of short-to-average height, which makes her the second shortest character in the game, after Natsuki. When in school, she wears the standard issue female school uniform consisting of a warm gray blazer fully unbuttoned and untucked, brown sweater vest, white shirt slightly unbuttoned and crooked at the collar and tucked, red ribbon that's displaced, dark blue pleated skirt, white knee-high socks and white uwabaki slippers with sky blue tips. When outside school, she wears a pink shirt with rolled-up long sleeves and blue shorts. On the morning of her death, she is seen wearing a brown collared white dress shirt, which has a pocket on each side, brown folds and six black buttons, the top one being unbuttoned, slim-fitting red shorts and was barefoot. She is exactly 5'2, and is 18 years old.
