Neon girls generally know a thing or two about makeup; this applies regardless of age. Some elementary and middle school students even try on a bit of light makeup themselves. Even so, their parents don't seem to mind—everyone has a desire to be beautiful, which is unrelated to age or appearance. They all went through this too, so they naturally see no problem with it. As long as the children don't wear heavy makeup and stand out too much at school, the parents let them be.
The cute little Ise Yu seems to have incorporated a bit of makeup skill in her dressing skills. However, Shirakawa Sawahei has been with her for so long, and he always saw her with a bare face. In short, she's just too lazy to put on makeup. It's not just her; the few girls in the Calligraphy Club also hardly wear makeup. Call it the privilege of pretty girls or plain indulgence. Shirakawa Sawahei has never seen Tsukimi and the others seriously wearing exquisite makeup in front of him.
