This is a book for Youmu-chan, who doesn’t have many things she can’t wear, so she can try on a variety of things. This time, I wore it exclusively for school swimsuits. This is a full-color illustration book with mainly illustrations and 3-panel comics. ◆There are also illustrations of School Swimsuit Youmu-chan by Otowa-sensei, Suzuno Naru-sensei, and Rosegardena-sensei on the guest page!
