Natsuki

17, 4'11, ESTP, Japanese, Natsuki appears to be a brash, blunt, cranky, and even arrogant girl at first, but she has a cute, softer interior, causing Monika to class her as the real-life embodiment of a tsundere. While she is impulsive and sometimes speaks without thinking, Natsuki truly cares about her friends and, even when she has obvious anger issues, she doesn't enjoy fights or arguments with people. Over the course of the game, it is shown that she worries about Yuri, and, on one occasion, she gives the protagonist a note asking him to help Yuri, fearing that if she spoke out then it would cause more arguments. Natsuki is very stubborn and has a hard time expressing how she feels and what she wants. When repeatedly challenged, she often becomes awkward and tongue-tied, then aggressive, and then simply bursts into tears. Natsuki is also shown to be less pushy and more relaxed when she is outside of school, as mentioned by the protagonist when she visits his home. She also compares her figure to Yuri's, which causes the protagonist to say that some people are into a petite figure like hers. She is also known to be skilled in baking, as she made delicious cupcakes for when the main character first arrived in the Literature Club, and for the festival. Natsuki's cute interior also involves a love of manga and anime, particularly those in the slice-of-life genre, and baking. She has been known to store her manga collection in the Literature Club out of embarrassment; another reason (hinted at) is because her father would be angry while the rest of the club obviously knows about her interest, and she is still hesitant to talk about it. Natsuki also likes cute things, such as cupcakes with cat faces, and prefers poems with cuter, happier words, though her own poems are still about sad things, such as being persecuted for one's hobbies. Natsuki believes that it's important to be able to express something deep with few words. Her simplistic writing style puts her at odds with Yuri, who has a more extravagant style. In Act 1, the protagonist is tasked with siding with Natsuki, Yuri, or asking for Sayori's help after an argument between Yuri and Natsuki regarding writing styles. Choosing Yuri will cause her to be offended, and the player attempts to read Natsuki their poem, Natsuki will immediately shoo them away. It is shown that she is a very lonely person who desperately craves affection from anyone. One example is during the third poetry-sharing session: if Natsuki has liked all the player's poems to date, she outright asks the protagonist if he thinks her poems are the best, which quickly shifts to her begging him to say they are, even if he hates them.

Natsuki has straight pastel pink hair, cut around chin length, and pink eyes. Her bangs are swept to the right, having two prominent strands of hair beside them. Her accessories consist of a red Japanese-style crossed hairclip, as well as two red ribbons tying two small ponytails on either side of her head, with the rest of her hair left down. Her canine teeth are longer than the rest of her teeth, making them visible when she opens her mouth wide enough. She is the shortest character in the Literature Club, a feature that results in people commonly mistaking her for a first year student. While in school, she wears the standard issue female school uniform consisting of a warm gray blazer fully buttoned and untucked, brown sweater vest, white shirt slightly unbuttoned at the collar, red ribbon, dark blue pleated skirt, white knee-high socks and white uwabaki slippers with sky blue tips. While out of school, she wears a short sleeved white shirt with a light pink cat face decoration on the left side with light pink trims lining the edges of the sleeves, light pink ruffled skirt with a black trim. Under the shirt, two black bra straps can be seen.
