Details were scarce at that point, but now GREE organized a big press event in Tokyo to introduce the show to a broader audience.
The dedicated website now says that the first episode of the Doliland anime will be aired on July 7, at 1130pm on TV Tokyo.
Screenshots from the anime:
What’s interesting is that the anime introduces new characters to the Doliland world: these characters will be made available as cards in the game one by one.
The first such character is Mikoto, pictured below (left: anime version, right: card version):
To drum up interest, GREE released a 3-minute Doliland trailer (“episode 0”), which is only accessible inside the smartphone version of the game: very clever.
