Namori is a Japanese manga artist and illustrator, born on June 25, 1987, in Takaoka City, Toyama Prefecture, and currently resides in Kyoto Prefecture. She is female and has B blood type. Her professional pseudonym is derived from a classmate who wrote the character "na" in a可爱 manner, combined with a randomly chosen "mori." Her self-portrait is a jellyfish, which has become a recurring mascot within her works. Namori has expressed that she aspired to become a manga artist since elementary school and is known to prefer working in coffee shops.

Namori is best known as the creator of the long-running manga series Yuruyuri, also known as Happy Go Lily. The series began serialization in Ichijinsha's Comic Yuri Hime S magazine on June 12, 2008. When Comic Yuri Hime S ceased publication, the series transferred to its sister magazine, Comic Yuri Hime, starting with the January 2011 issue. Yuruyuri has been collected into numerous tankobon volumes, with over twenty-three volumes released as of late 2024. The manga's popularity led to the creation of a spin-off series, Omuro-ke, which began serialization on the Nico Nico Seiga website in July 2012. Prior to her breakthrough with Yuruyuri, Namori worked on Puchimon!, a manga adaptation of the light novel series of the same name written by Midori Natsu, which ran from 2007 to 2009.

The success of Yuruyuri has generated multiple anime adaptations. The first two television seasons were produced by studio Doga Kobo, airing in 2011 and 2012 respectively. Subsequently, an original video animation titled Yuruyuri Nachuyachumi! was released in 2015. This was followed by a two-episode television special, Yuruyuri Nachuyachumi!+, and a third full television season, Yuruyuri San Hai!, both also airing in 2015. These later installments were produced by TYO Animations. Additional anime projects include a series of short episodes titled MiniYuri and an original video animation released in 2019 to celebrate the manga's tenth anniversary.

Beyond Yuruyuri, Namori has contributed to the industry in several other capacities. She served as the original character designer for the original television anime Endro~!, which premiered in January 2019. She was also the character designer for the anime Release the Spyce. Her early professional work included providing illustrations for light novels such as Puchimon! and Reset na Kanojo. She has contributed illustration work to a wide range of popular series, providing end cards for anime episodes of Nisemonogatari, Nisekoi, and Watashi ni Tenshi ga Maiorita!. She also participated in numerous manga anthologies for franchises including Little Busters!, CLANNAD, Persona 3, and Persona 4. Namori's artistic identity is strongly associated with the yuri genre, focusing on comedic and lighthearted stories about relationships between girls. Her work is known for its moe aesthetic and has been credited as a landmark title in popularizing yuri-themed media for a broader audience. Her significance in the industry is also underscored by her prolific output and her reputation for drawing quickly and producing a high volume of work.
