The first 2/3rds or so of this episode had some pretty good comedic moments, such as Jun not holding the PFP the right way, and Keima's attempts at doing bad, only to realize he is both a protagonist and not a protagonist. Given his game obsession, he's closer to the protagonist's best friend, really. All the stuff with Nikaido was great as well, including her "information".
On the subject of Jun, interesting that her revelation should come about so soon after yesterday. However, she doesn't seem to be hiding any grudges or troubled pasts (mostly) beneath that exterior. Her passionate self is real, and I admire her for that. So many times a passionate exterior is just a front, but why not, when that passion is stripped away, have more passion hiding beneath it? I sympathize with her to quite a degree. She shouldn't end this route by removing her passion - for one, that would be tremendously stupid - just rechannel it into something that benefits everyone.
Jun, go for it!
