Mashiro Shiina

Height: 162 cm

Mashiro is the female protagonist of the story. She is the resident of room 202. She is a world-famous artist who transferred into Suiko as a second-year to learn how to draw manga. Although her artwork is widely admired by the world, in spite of her young age, she knows nothing other than drawing and has an extreme lack of common sense and living ability. Due to this, Sorata is forced to handle Mashiro's living chores, to the point that he even has to pick out underwear for her, or she will go out without them.

In the third novel, Mashiro starts to grow feelings for Sorata, and she even claims that she cannot live without him. In the eighth novel Sorata confesses his feelings for her and in the next novel, they are officially a couple.

Given her only academic strong point is art, she does very poorly in other subjects. Utilizing her photographic memory allows her to succeed in these subjects.
