EDIT: Uwaaah, The Girl Who Leapt Through Time was much better than I expected ;A; The art reminds me quite a bit of the old Digimon movie... you know the one with Taichi and Izumi as the main characters. But I like it 8| The surroundings, for example, are really pretty -like Makoto-chan's home.

It's a pretty sad movie in some parts too 8|;; Kinda bittersweet for a while, too. But the ending is genki~ It makes me think about Hourglass of Summer... ha~ sugoi deshou~~~
