Keigo Shinzo debuted as a manga creator in 2008 with his work "Nankin" and has since gone on to create award-winning hits such as Bokura no Funkasai (Our Eruption Festival). In 2016, his work Moriyamachuu Kyoushuujo (Moriyamachu Driving School) was made into a movie, and two years later, his series Tokyo Alien Bros. was adapted into a live-action drama. During the coronavirus pandemic, when Keigo was diagnosed with lymphoma, he decided to write the one-shot "Akusei Rinpashu de Nyuuin shita Toki no Koto" (About the Time I Was Hospitalized for Malignant Lymphoma), in which he chronicles his road to recovery as well as how he got the idea for his award-nominated series Hirayasumi.
