Musawo is the pen name of a Japanese manga artist, known in the industry as the original creator behind the popular romance series Love and Lies. While Musawo maintains a relatively private public persona, several authoritative sources confirm basic biographical details, including Japanese nationality and male gender. The name Musawo is a pseudonym, and the creator is also known by the real name Tsumugi Musawo, though this is not widely used in official publications.

Musawo is best recognized as the writer and illustrator of the manga Love and Lies, known in Japanese as Koi to Uso. The series was first published digitally in DeNA's Manga Box app in both Japanese and English starting in August 2014. Within a month of its launch, it became the app's most popular work, amassing 3.5 million viewers. The manga concluded its serialization in January 2022, and its chapters were compiled into twelve physical volumes by Kodansha. The final volume was notably released in two distinct editions, each featuring a different ending for the protagonist, allowing the story to conclude both romantic routes.

The success of the original manga led to several major adaptations. A television anime adaptation produced by Liden Films aired in Japan from July to September 2017. The series was directed by Seiki Takuno and consisted of twelve episodes. In the same year as the anime, a live-action film adaptation was also released in Japan in October 2017, which featured original characters and a different central love triangle compared to the source material. Additionally, an original anime DVD was bundled with the eighth volume of the manga, which shipped in November 2018. Love and Lies is noted as Musawo's first series to be published in English.

Following the conclusion of Love and Lies, Musawo announced a new manga series titled Kareshi Tokidoki Kanojo, which translates to My Boyfriend Sometimes is a Girlfriend. The series began serialization in Kodansha's Bessatsu Shōnen Magazine on June 9, 2023. Described as a romantic comedy, the story centers on a high school boy who keeps an unimaginable secret from his girlfriend.

Thematically, Musawo's work frequently explores the tension between societal expectations and personal desire. Love and Lies is set in a dystopian version of Japan where the government assigns marriage partners to sixteen-year-olds based on genetic compatibility to address declining birth rates, effectively outlawing romantic choice. The narrative focuses on the protagonist Yukari as he navigates his long-held feelings for a childhood friend against the reality of his assigned government partner, examining concepts of forbidden love, loyalty, and rebellion against state control. This focus on internal psychological conflict and the definition of love itself forms a core part of the artistic identity Musawo established with this debut hit.

In terms of industry significance, Musawo is recognized as a creator who successfully leveraged the digital manga market, achieving rapid and widespread popularity through the Manga Box app before securing traditional print publication and international licensing deals. The production of simultaneous anime, live-action, and original video animation adaptations within a short timeframe underscores the commercial impact and broad appeal of the creator's original work. Kodansha USA Publishing has released the English language versions of Musawo's manga, cementing the creator's presence in the North American market.
