The secret after-school activities of beautiful girls in Shibuya uniforms. Karaoke after school? Arcade? No, it's not that. They're working part-time jobs, and they keep it a secret from their friends. The reason is simple. They want some pocket money to spend when they hang out with the others. It's fine as long as no one finds out. And with masks on, most of their faces can't be seen... And now, these beautiful girls in uniforms are doing some pretty risqué things, and the footage has been leaked without their permission!
