I need an anime movie

You can safely assume, I've watched every Ghibli. If it's unpopular from Ghibli, Feel free to suggest it.

I was going to watch Summer Wars, but my sister wanted to watch it too. So I'm here.

I never ever got in to Kara no Kyoukai and if anyone mentions that tear jerker of a movie called "5 centimeters per second"...
I'll go cry in my pillow fort again
