Shiina Mashiro

Mashiro is the main heroine and resides in Room 202 of the Sakura Dormitory.

Mashiro is a world famous artist who transferred into Suiko as a second-year to learn how to draw manga. Although her artworks are widely admired by the world in spite of her young age, she knows little to nothing other than drawing and is extremely reliant on others just to get by, lacking even the most basic common sense. As a result, Sorata is forced to constantly take care of Mashiro, to the point that he even has to pick out underwear for her, or she will go out without them.

She has very bad grades, since she cannot pay attention to the class, but she can still pass the make-up exams by remembering all of the answers with her art talent.
