A student at Hinominami High School with excellent grades and a refined, beautiful appearance, serving as the Student Council President in her third year. She is a former delinquent once known as the "Beast of Hino," but she reformed upon entering high school and hides her past by acting as a model student. While she usually speaks politely, her true nature is rough and masculine. After Nokotan sees through her facade and starts dragging her into chaos, her true self is eventually revealed to those around her during the sports festival, yet she is accepted regardless. She is kind-hearted, caring, and has a somewhat naive and easily flustered side. Currently, she serves as the president of the Deer Club, enjoying it as a place where she can be herself. She is the sole straight man of the group. First person: I (polite). Second person: Name (no honorific), you (casual), you (blunt).

A girl attending Hinominami High School and Koshitan's classmate. A beautiful girl with a short haircut, but she has deer antlers growing out of her head and claims to be a mysterious "human-deer hybrid." She loves deer crackers, always carries them, and can communicate with deer. Despite her many eccentricities, she is naturally accepted by those around her and is especially admired by her juniors. She is bright and moves at her own pace. She has a strong sense of gratitude and always tries to repay those who help her. She founded the Deer Club and is a mysterious figure involved in deer-related part-time jobs and Shinto rituals; much of her background and true identity remain unknown. She frequently causes nonsensical events like something out of a gag manga. First person: I (standard). Second person: Koshitan (for Torako), Koshian (for Anko), Bashame (for Meme).

Koshitan's younger sister. A first-year high school student and a perverted girl with an extreme sister complex who utterly adores her sibling. Usually elegant and calm, she becomes a dangerous person who views anyone in her sister's way as an enemy, showing a violent yandere side when triggered. She joined the Deer Club as her "sister's caretaker." Initially, she viewed Nokotan as a rival and fought her, but they reconciled after Nokotan saved her life. She possesses high combat and physical abilities, wielding kunai and katanas, and is capable of setting traps and performing advanced engineering. She is also highly intelligent and technically skilled, even building underground facilities. She often acts alone and occasionally gives her sister cold, blunt reality checks. She is good at cooking and has a domestic side, but her excessive love for her sister often leads to radical behavior. First person: I (polite). Second person: Big Sis (for Torako), Bashame (for Meme). Quotes showing her love: "I want to be with Big Sis 24 hours a day, 365 days a year, every minute and every second! ♡", "And if possible, I want to make it so Big Sis can't live without me," "Haa... ♡ Big Sis's scent... ♡ I can't get enough... ♡"

A new first-year student who joined the Deer Club out of admiration for Nokotan after being saved by her. She is characterized by her bun-like wavy hair and a constant wide-mouthed expression. She refers to herself as "Bashame." Extremely independent, her motto is to "stay true to oneself," and she remains unfazed in any situation, though she can be stubborn and audacious. On the other hand, she has a straightforward and honest personality and can recognize the talents of others. She treats Koshitan the same even after learning her true nature, showing her good social skills. She is indifferent to things that don't interest her and isn't great at studying, but she has a serious obsession with rice cultivation. A massive lover of white rice, she is a big eater who even brings her own rice cooker. Her obsession with food is strong; she hates wasting ingredients and shows unique creativity regarding meals. Usually relaxed, she is a unique character who commits fully once she decides to do something. First person: Bashame. Second person: Koshitan-senpai (for Torako), Nokotan-senpai (for Noko), Anko-chan (for Anko).

The Student Council Vice President at Hinominami High School. She is a serious, reliable overachiever who ranks second in her grade. While she respects Koshitan, she views her as a strong rival and aims for the position of Student Council President and the school's idol. She is proud and hates losing, but she is actually quite easy to manipulate and ends up enjoying the Deer Club after being swept up in Nokotan's antics. She is essentially a sensible person and a straight man, but she also has a compassionate side, such as worrying about Koshitan. Standing at only 132cm, she always carries her own step stool. Her nickname is "Neko-chan," but Nokotan calls her "Shikayamada."

A second-year student at Hinominami High School and the Student Council Secretary. She has a kind and serious personality but is prone to negative thinking and leaps of logic, often associating minor mistakes with death. She is a virtuous person who rarely speaks ill of others. She can be a bit of a show-off, claiming to be good at cooking despite being terrible at it—a bit of a space cadet. She is a big eater and so bad at cooking that she once put eggshells into her rice with raw egg. She is close with her childhood friend Chiharu Tsubameya. Although generally timid, she has surprising initiative, such as performing the "Tanuki Dance" to match others. Speaks politely.

A second-year student at Hinominami High School and the Student Council Treasurer, nicknamed "Tsubame." Characterized by her short black hair and hollow eyes, she has a cool and calm atmosphere, speaking rarely and in a low voice. She is close with her childhood friend Tanuki, and Koshitan sometimes feels like she is being glared at by her. In reality, she is a huge fan of Nokotan and was simply envious of Koshitan's proximity to her. Whenever Nokotan is involved, her usual expressionless face gains highlights in the eyes, and she becomes a passionate devotee who takes countless photos and goes to see her. She calls Noko "Nokotan-senpai." Speaks politely.

The faculty advisor for the Deer Club and an English teacher. She is the homeroom teacher for Torako and Noko. For some reason, she gets along strangely well with Noko, which led her to easily approve the establishment of the Deer Club, making her a key figure in its existence in many ways. She appears occasionally afterward, often serving as a moderator for events or meetings.
