Yup, it's definitely meant for children. Of course, I'm not saying that it's bad. In fact, I think it's one of the best I've seen so far. It's not some stupid merchandising venture like many of the other children's anime, and it's not some stupid "same message over and over" deal either.
Iyo-chan makes this device that lets people talk to plants. It brings up some interesting questions. Since we're talking about (and with) plants, it's the perfect time to introduce Osiris. There's actually a very good reason why Hisham created Osiris, although he's a bit misguided about having her fight with Gargoyle. A lot of adults are more misguided than children in real life, after all.
First pressing comes with, wow, 40 cards! That leaves only 6 more cards and one more joker. Not bad!
And remember what I wrote in DVD volume 1 listing? I wrote, "I think Futaba's Mom should be the Ace of Hearts." Guess what? For your information, I am aware of the official web site with the complete information, but I was _not_ aware of the site when I wrote the volume 1 listing, so it really was a guess.
Futaba talking with Hanako (voiced by Matsuki Miyu!). Background is nicely boke'ed out.
