This article is about manga-based messaging for risk communication on COVID-19, describing the practice of collaboration between a group of experts and a popular manga artist. Collaborative storytelling through popular manga provides an effective discussion platform for diverse experts in various specialties, ages, and genders to discuss a topic in a short time. These “stories” can integrate social meaning, legitimacy, and a local context into scientific messages. They also provide the public with a deeper understanding of the messages through the characters and their “real-life” situations, as long as the messages remain consistent with the worldview of the original work.
