《Details》 A student at Hino Minami High School, she is a beautiful girl with excellent grades and a refined image, serving as the student council president in her third year. She is actually a former delinquent once known as the "Beast of Hino," who reformed upon entering high school and hides her past by acting as a model student. While she usually speaks politely, her true nature is a rough, masculine way of talking. After Nokotan sees through her facade and drags her into chaos, her true self is eventually revealed to those around her during the sports festival, but she is accepted regardless. She is kind-hearted and caring at her core, though she has a naive and easily flustered side. Currently, she serves as the president of the Deer Club, enjoying her daily life there as a place where she can be herself. She is the sole straight man (tsukkomi) of the group. First person: I (polite/feminine). Second person: Name (no honorific), you (blunt), you (rough).

《Details》 A girl attending Hino Minami High School and Koshitan's classmate. Though she is a beautiful girl with a short haircut, she has deer antlers growing out of her head and is a mysterious being who calls herself a "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 adored by her juniors. She is cheerful and marches to the beat of her own drum. She is deeply loyal and always tries to repay those who help her. She founded the Deer Club, but much about her remains a mystery, including her background and true identity, as she is involved in deer-related part-time jobs and Shinto rituals. She often 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).

《Details》 Koshitan's younger sister. A first-year high school student and a perverted girl with an extreme sister complex, obsessively adoring her older sister. Usually elegant and calm, she becomes a dangerous individual who views anyone in her way as an enemy when her sister is involved, showing a violent side when she goes yandere. 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 calm, sharp retorts. She is good at cooking and has a domestic side, but her love for her sister is so intense that her actions tend to be extreme. First person: I (polite/feminine). Second person: Onee-chan (for Torako), Bashame (for Meme). Famous lines showing her love: "I want to be with Onee-chan 24 hours a day, 365 days a year, every minute and every second! ♡", "And if possible, I want to make it so Onee-chan can't live without me," and "Haa... ♡ Onee-chan's scent... ♡ I can't get enough... ♡"

《Details》 A new first-year girl who joined the Deer Club out of admiration for Nokotan after having her life saved by her. She is characterized by her dumpling-like curly hair and a face that always has its mouth wide open. She refers to herself as "Bashame." She is extremely laid-back and lives by the motto of "being true to oneself," remaining unfazed in any situation, though she can be a sore loser and somewhat brazen. On the other hand, she has a straightforward and honest personality, capable of acknowledging the talents of others. She treats Koshitan the same even after learning her true nature, showing she is good with people. She is indifferent to things that don't interest her and isn't great at studying, but she is deeply committed to rice cultivation. A huge fan of white rice, she is a big eater who even brings a rice cooker to school. She has a strong obsession with food, hates wasting ingredients, and shows unique creativity. While usually slow-paced, she is an eccentric character who goes all-in once she decides to do something. Second person: Koshitan-senpai (for Torako), Nokotan-senpai (for Noko), Anko-chan (for Anko).
