Sayori is portrayed as a talkative person, being very cheerful and kind and the archetype of a Genki Girl. She is very clumsy and notorious for finding ways to accidentally hurt herself or to drop things, as well as tricking people just to get food. She is usually the only character, other than the protagonist, capable of breaking up arguments, and she is described as being paramount to keeping a relaxing atmosphere in the Literature Club, which becomes even more apparent after her suicide. Monika notes that while she may look like a good leader, Sayori is usually better when it comes to dealing with people. Sayori 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.
