I like how the just subtly snuck Yuzuko in there. I liked Yuyushiki and all, but it wasn't anything that big or eye catching. I wonder why the artist chose that and not something more popular or modern.
Just check more works by the same artist, they clearly likes yuri shows. Also, data processing club.
There always is a slight chance that it looks like Yuzuko by coincidence. If you compare the two, the one in this picture has a slightly different uniform
