Waiting for 7, but I was surprised at just how severely they toned things down.
Spoiler:
First, Chizu's relationship with her teacher is known from the start here, so Kako immediately asks if she's going to see him, and she tells him directly that she did it with him. In the manga he asks her what's wrong with wanting to do it once before dying after she stops his rape attempt, and she replies simply that she already has, to which he asks if it was with Kirie. I'm not entirely surprised though somewhat disappointed that they changed Kako's death to a private accident instead of getting his throat slashed in front of everyone. Now that Chizu's teacher hasn't gone so far as to distribute the sex videos and even let others "have" her before taking a new prey, I'm wondering just how much they're going to remove from other stories. I imagine it's pretty much a given Chizu's not pregnant, since she'd know by now and wouldn't try to kill her teacher with that knowledge. Also, her battle decisions don't seem so compelling when she already knows about her sister's relationship. I sadly imagine we aren't going to see Mako rip the roof off a hotel to pick up her naked classmate. Too bad, it was hilarious when she and her boyfriend popped up, still nude, in her mom's car!
I just hope they keep the less risque stories unchanged. I really loved some of these stories and don't want to see them all butchered.
