It wasn't a perfect ten, but it was okay.
Bad points:
Time was inconsistent... Yuzuki didn't seem to age in ten years (
), and Aoi's voice still hasn't changed... -_-
Sana's past, in the end, took 2 minutes to complete...
Nothing was shown on what the other characters were doing before the huge time jump.
It finished up Nanaka's story at least, showing that the arsonist was the dad.
I wouldn't completely blame him though. Nanaka's mom shouldn't have provoked him. She isn't blind, so she could clearly see how murderous he looked, but she just went ahead and put up a "so what" attitude. Thanks to all of that, the whole family shattered apart.
Sana tried to kill himself, became a hikikomori, and for a change of atmosphere, came back to the town. Lots' of people guessed this, or parts of it.
It's fine, though I question the wiseness of sending a suicidal kid off by himself.
Random points:
Incest end... -__-...
Yota turned into Renji (ef)...
