No, really. Why? Well, the answer is because I felt like it. Alternatively, this is pretty much the last episode that affects the status quo of the series beyond "the conflict escalates and is resolved" before season 3 happens, so if you're worried about spoilers, but don't want to wait for the S2 subs to be completed before watching more subbed _PriPara_, this is just about the next best thing.
Oh yeah, I did the script properly but I skipped translating the OP.
