Description
Kumin Tsuyuri is a second-year student at Icho Private High School. During her first year, she made a valiant but unsuccessful attempt to establish a dedicated "Nap Club" due to lack of interest. Finding companionship in her second year, she integrated her passion for napping into the Far Eastern Magic Napping Society of Summer after meeting Rikka Takanashi and Yuuta Togashi.

Her background includes living overseas after kindergarten because of her father's work, followed by homeschooling until high school. This sheltered upbringing cultivated an innocent, naïve personality characterized by old-fashioned ladylike manners and ethics. Physically, she possesses dark pink eyes, short dark brown hair, and fair skin, standing 155 cm (5'1") tall with a small mole on her right breast.

Kumin's defining passion is napping, which she considers her primary hobby. She is rarely seen without a pillow, often carrying multiple, and has been observed sleeping in a full futon on school grounds. Her napping habits include curling up like a cat, sleep-talking, and associating specific pillows with themed dreams—her "sunny spring day pillow" evokes grassy meadows. She also harbors a fondness for cats.

Personality-wise, she is laid-back and friendly. She earnestly tries to understand the chuunibyou delusions of Rikka and Sanae Dekomori despite not sharing such tendencies herself. She exhibits curiosity, particularly in her fascination with Makoto Isshiki's shaved head and her enjoyment of fight or horror scenes. In Season 2, she consciously attempts humor by crafting puns, though they frequently fall flat.

Throughout the series, Kumin acts as a supportive figure. In Season 1, she temporarily assumes the mantle of "Tyrant's Eye" during the school festival after Rikka relinquishes her powers and later informs Yuuta that he was the catalyst for Rikka's chuunibyou. During the movie *Take On Me*, she suggests Yuuta and Rikka elope to prevent Rikka's sister Touka from taking her to Italy. When conflict arises between Yuuta and Rikka near the movie's climax, Kumin travels to Aomori with Satone Shichimiya to assist, emphasizing that the resolution rests with them.

Her surname, Tsuyuri, uses an unusual reading for the characters 五月七日, which Yuuta initially misreads as the more common "Gogatsu Nanoka" (May 7th), incorporating the characters for "five," "moon," "seven," and "sun/day." Kumin is an anime-original character who does not appear in the light novels until Volume 3.
