I'm really liking this story so far...but...
the way you're writing it makes it seem more like the original.
I mean, in the sense of the characters...
they're acting a LOT like their counterparts...too much like them...
oh, and by the way, 2p america doesn't have glasses (except for his sunglasses) he doesn't have Texas (the glasses not the state)

1. The mochi is the key to getting out of the house quickly. It's stuck in a hole in the wall that goes to the outside. If only they could get it out, Germany could probably widen the hole and they could escape. Unfortunately, the programmer of the game made them all quickly-giving-up, useless cowards.
2. 'Could you help me get a mochi out of the wall?' It only makes sense if you watch Hetalia. Wait, no, it still doesn't make sense. :P

NOOOOOOOO! QAQQQQQQ! Oh, and on DeviantART, there's this user who actually made a sequel of HetaOni! :DDDD
