More likely he'd been fapping so hard he forgot all about it.
I am putting my money on this. Poor Tatsu, all he has is 2D and his sister. Both are unattainable.
I am almost nearing the end of Heaven's Feel now. I am playing the Realta Nua version (version 2). The h-scenes are removed and replaced with vampire-styled scenes. But the music has improved a LOT. (And voice acting to a extent). The Realta Nua version is definitely more enjoyable.
There's a patch for the h-scenes. I'll agree with the music bit, I was actually pretty disappointed that the F/SN soundtrack on the tracker didn't have the Vita version.
