Since the anime's Tatarigoroshi-hen has ended, I have posted the 3rd "Naka
nai Kimi to Nageki no Sekai" video:
Nakanai Kimi to Nageki no Sekai -Utage-
Personally, this one's my favorite out of the bunch. Probably because Tatarigoroshi-hen was my favorite chapter from the game.
EDIT: It should work now. ^^;
