In Kore Kaite Shine, first-year high school student Ai Yasumi lives on Izu-Oshima, where manga matters to her more than anything else. When she learns that Hoshi no Rei, the manga artist she has followed and admired for years, will exhibit at COMITIA, she heads to Tokyo hoping to see the creator whose work inspired her. What begins as a simple trip becomes a turning point when an unexpected encounter pulls her into the demanding reality of making manga.
As Ai starts asking how someone becomes a mangaka, she discovers how much she still has to learn about a craft she thought she understood. Passion alone is not enough; every page brings its own challenges, and curiosity, determination, and steady work matter as much as love for the medium. Alongside figures such as Rei Teshima, Kore Kaite Shine follows Ai's first real steps toward creating stories of her own, tracing the excitement and frustration of entering the world of manga creation and turning admiration into practice.
