Well, the character designs are cute. So that's a good start. Can't say much more than that. Why make a teaser and announce they'll reveal it in Aug? They... kinda revealed it already. Why didn't they just show it all? I really don't get this. I guess it fills the 'teaser' role in its title. Whata tease...

"From the trailer, we see that the game is set in an country called “Ashihara Nakatsukuni,” that two girls seem to be key figures, and that the genre is “dramatic RPG.”"

1) what the heck is a dramatic rpg?
2) the first girl sucked through that wormhole, says "brother" in japanese right?

This trailer does like nothing for me... no real hype for it.  Also I suspect this might be a mobile game.

Is there such a thing as a non dramatic RPG?

"We are proud to annouce that we will have more information about this title later.  Please be excited"

 Japan loves it's premature pre-ejaculate, especially Square.

Expectations set low now...

That's cool and all but when are you going to make Chrono 3, SE?!

Obviously a mobile title.. So thanks i'll pass.

All of their games tend to be dramatic (overly) though, so I believe them.

That trailer tells me absolutely nothing about this game.
