There are some date shenanigans in this demo:
• There's a woman in the cafe section of the pokemon center that says that the owner will return in "about a month", Sun/Moon comes out November 18th, a month after this demo came out
• Greninja's date met is 10/17/2013, this is the date that the Pokemon XY anime began airing in Japan
• The date met for Kukuli's Pikachu is 5/10/2016, this was when Nintendo officially announced Pokemon Sun/Moon
Clever stuff
Also, whenever your Greninja transforms, it should play the song from the anime

That'd be pretty cool
In addition, during the post game, there is a woman in the ferry terminal who is nervous and wants you to see her off in
24 days, 24 days from October 18th is November 11th, November 11th is the release date of the Alola collection of Pokemon trading cards
And there's an officer on the pier that mentions some kind of deal happening in
18 days, November 5th, i can't really find out what this relates to other than a 'pokemon club', a pokemon tournament being held in Michigan, and some kind of 'lure-a-thon' and a meetup/photoshoot at Youmacon, which is also being held in Michigan
Also, the traffic cones on the pier are black and blue
October 19th, the guy outside the pokemon center will give you something, not today, not the day after tomorrow, it HAS to be the 19th
To the far left of the city is a woman who hurt her ankle, she said to meet her spot in that
5 days, because i've been playing this demo before and after 12 o'clock, i don't know if that's the 23rd or the 24th...
