Yuki Kodama is a Japanese manga artist known for creating works that range from supernatural action comedies to character-driven period dramas. Born on September 26 in Sasebo, Nagasaki Prefecture, Kodama made her professional debut in 2000 with the one-shot series Zakuro, published in the magazine Cutie Comic.

Kodama first gained widespread recognition for the manga Kids on the Slope, which was serialized in Shogakukan's Monthly Flowers magazine from 2007 to 2012. The story, set in 1960s Sasebo during her own childhood, follows two high school boys who form a deep bond through their shared love of jazz music. The series was the top-ranked manga for female readers in the 2009 edition of the Kono Manga ga Sugoi! rankings and won the 57th Shogakukan Manga Award in the general category in 2012. In the same year, Kids on the Slope was adapted into a twelve-episode television anime series directed by Shinichiro Watanabe, with music composed by Yoko Kanno.

In contrast to the grounded drama of Kids on the Slope, Kodama is also the creator of Blood Lad, a manga written and illustrated under the name Yuuki Kodama that was serialized in Kadokawa Shoten's Young Ace magazine from September 2009 to September 2016, spanning seventeen volumes. Blood Lad follows Staz, a vampire boss in the Demon World who is more interested in Japanese otaku culture than in traditional vampire activities, and his quest to revive a human girl who becomes a ghost after wandering into his world. The manga was adapted into a ten-episode anime television series that aired from July to September 2013, produced by the studio Brain's Base. Kodama also wrote and illustrated Bloody Brat, a spin-off manga series, and contributed to an anthology of Blood Lad short stories.

Kodama's other notable works include Tsukikage Baby, a drama serialized in Monthly Flowers from 2013 to 2017 that focuses on multiple families in a traditional Japanese town and incorporates the Owara folk dance. Chiisako no Niwa ran in the same magazine from 2017 to 2018, followed by Ao no Hana, Utsuwa no Mori, which was published from 2018 to 2022 and centers on ceramic and pottery artists. In 2022, Kodama began serializing Wolf's Daughter: A Werewolf's Tale, which was licensed for English release by Seven Seas Entertainment in 2024. She has also created one-shot works such as Hōsekibako no Ningyo in 2013 and Underground in 2014.

A recurring theme in Kodama's work is her ability to bring niche cultural activities to the forefront of her narratives. She has depicted jazz music in Kids on the Slope, traditional Owara dance in Tsukikage Baby, and pottery craftsmanship in Ao no Hana, Utsuwa no Mori. In an interview, Kodama explained that she chose jazz for Kids on the Slope because of the American military base in her hometown of Sasebo, feeling that jazz music, which was brought into Japan through the post-war occupation, suited the location's atmosphere. She has described the challenge of depicting silent arts like dance on paper, noting that she worked with local dancers to ensure accuracy in her illustrations for Tsukikage Baby. Several of Kodama's series have consistently ranked highly in the Kono Manga ga Sugoi! rankings for female readers, with Tsukikage Baby placing third in 2014, Chiisako no Niwa placing eighth in 2019, and Wolf's Daughter placing eighth in 2024.

Beyond her original manga series, Kodama has contributed as an illustrator and character designer for other projects. She served as the illustrator for the manga adaptation of ID: INVADED #BRAKE-BROKEN and worked on character drafts for the ID: INVADED anime series.
