Though Luna had been banished for 1000 years, she was able to latch on to one aspect of modern life very quickly: video games. Specifically, the Pokemon games. Introduced to Pokemon Black and White, she eagerly anticipates the sequels due out the following day.
And Luna won't stop talking about it.
So in attempt to take her mind (and theirs as well) off the waiting and make the release date anticipation a little more bearable, a few of the others decide to take her on a trip down their memory lane by introducing her to the aspects of Pokemon they grew up with.
Includes call-backs to previous Pokemon generations, both games and anime. Warning: May cause nostalgia-flashbacks.
(I wrote this the day before Black 2 and White 2 came out and finished it at night, but since it was so late I figured I'd wait to post it on the game's release date rather than try to get it approved and have it be fully up at midnight or so when few would be online. And then it took a while to get approved.)
