Storyline is about a couple of kids in a world where they have a pet dog but they can't see it unless they're wearing goggles/glasses... There are certain areas with damaged code on the walls (just outdoors, beside the sidewalk), and they end up joining a group of kids who look after areas that are damaged like that and fix it.
If they can't complete fixing the code in time, a huge peanut shaped thing appears that they call ____Chan and it has 5-7 orbs in it's chest that pop out and fly around... The orbs and the huge-Chan have lazers for eyes and cannot cross into shrines or sacred areas. A few episodes in there's an older, higher level girl who can draw up her own shrines with chalk so that Huge-Chan can't see her.
I know I babbled, but I DESPERATELY want to find it again! It was SOOOO good! If you know the name of this anime, please, please inform us! Me and my room mate really want to know what happens next!
