Description
Ayumu Niikura is a main character in the anime CITY The Animation. She is an 18-year-old freshman attending Mont Blanc University and lives in room 101 of the Mokumesei Manor apartment complex. Her first name has not been officially confirmed within the source material, with some references pointing to Ayumu as a name from an early character prototype; she is known to use the pseudonym Michael J. Niikura for certain creative activities such as photography competitions.

Niikura is an aspiring photographer who is deeply passionate about her craft, often carrying a rectangular digital camera that she has owned since her high school days. While she strives to be the mature and responsible member of her friend group, her personality is complex and marked by a sharp contrast between her usual calm demeanor and a famously short temper. When pushed to her limits by the chaotic behavior of those around her, she is known to fly into dramatic, hot-tempered rants, using a handmade paper fan for comedic retorts in a way that highlights her role as the straight woman of the trio. Despite these outbursts, she is generally friendly, supportive, and can display a slightly mischievous or cunning side on occasion.

Her role in the story is central as a member of the Mont Blanc Trio, navigating the often absurd everyday life of the city's residents. She shares a particularly deep bond with Midori Nagumo, a friendship that began during her high school years. At that time, she greatly admired Nagumo for her achievements in sports and was inspired to take up photography, largely to capture images of her. A cherished memory from this period is a rare photograph of Nagumo, who typically refused to have her picture taken, which Niikura kept inside a pendant that she held very dear. This friendship is also playfully chaotic, as Nagumo frequently asks Niikura for money, leaving her perpetually wary of her friend's financial requests.

Her other key relationship is with Wako Izumi, whom she considers her master in photography. While she respects Izumi's skills, she is constantly caught off guard by her unpredictable and fanciful behavior, such as when Izumi decides to sleep in Niikura's closet. Outside of her immediate friend group, Niikura has, by chance, become acquainted with members of the City Nan High School Soccer Club, who affectionately refer to her as Boss, a testament to her spirited and commanding personality. She also owns a yellow scooter, which she uses to get around the city.

In her development, Niikura is depicted as a dedicated, if occasionally unsuccessful, photographer who keeps trying to improve her skills. She worries about how her actions affect others, and even her most aggressive tsukkomi, delivered with her paper fan, are noted by friends to be painless, reflecting an underlying kindness. Her notable abilities include her quick-witted banter and comedic timing with her fan, as well as her persistent dedication to photography, even if her subjects sometimes veer into the unusual, such as photographing broccoli.
