In episode 4, the year is 2025!!! You know, these time jumps in each episode does form quite of bit of melancholy for Rin and Mimi. Especially when lots of stuff are changing with the people they know keep on getting older, and they're pretty much stuck.
And with this time jump now deals with Kouki's son Teruki who's in college right. [spoiler] And in this future, everyone got addicted in the online world a.k.a. 2.0 in which the real world, 1.0, is starting to looks pretty crappy. The basic plot is that Teruki witnessed a murder of Ruon which doesn't seem right because Ruon is just a virtual idol in the internet (and not to mention the real Ruon died in the past). And now Teruki is on the run.
And this episode concluded with a bit of a twist. Ruon revealed to be a very obsessive, crazy android who wanted Teruki all for herself. Thankfully Rin was able take her out by throwing her and herself into the jet engine. Now how the heck is Rin going to regenerate from that?!!
