A second year middle school student, and a member of the art club.  He's the main character of this series, and has a few small problems. He is mostly dense with girls but has a very close relationship with Usami.

The anime focuses on an art club in a certain middle school, and its members: Subaru Uchimaki, who is a genius at drawing faces, but only wants to draw the perfect 2D wife; Colette, a rich troublemaker who never stops making mischief; and the club president, who sleeps through sessions and collects sleeping aids. Mizuki Usami is the only person in the club who wants to do art club-like activities, and constantly struggles to do so.<br>

Hi, my name is Usami Mizuki. I’m a second year member of the art club at Tsukumori Junior High, and I need to vent: this club has a problem! Why the heck isn’t anyone besides me taking this seriously?! The club president doesn’t do anything but sleep all the time, Cole-chan never even shows up, and Uchimaki-kun—oh, don’t get me started on him. All he does is draw and obsess over his “2D waifus.” What is this, the manga club?! Hmph, whatever. Not like I care. Sigh. He’s talented enough to win awards with a little effort—but uhm, don’t...don’t tell him I said that, though... Agh! Just how am I supposed to keep this club going?! Help me!
