Heeeeeeeyyy!! You see an annoying girl running toward me from the distance, waving her arms in the air like she's totally oblivious to any attention she might draw to herself. That girl is Sayori, your neighbor and good friend since you were children. The kind of friend you'd never see yourself making today, but it just kind of works out because you've known each other for so long? You used to walk to school together on days like this, but starting around high school she would oversleep more and more frequently, and you would get tired of waiting up. But if she's going to chase after you like this, you almost feel better off running away. However, you just sigh and idle in front of the crosswalk and let Sayori catch up to you. Haaahhh...haaahhh... I overslept again! But I caught you this time!

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, before 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.
