Assuming that the description of Kuwadorian's basement in episode 4 is the real thing, Kinzo having torture equipment and a variety of cages below the house feels fairly notable. This is the place he built specifically to house Beatrice II and had no purpose beyond that.

Like obviously we are all in agreement he raped Beatrice II but the story never really goes into detail on this part of it at all and I find that odd.

  
Especially since in the same episode Sayo Beatrice (who I assume is playing the role of Beatrice II when she says this) states:

  
"Don't worry \[Kinzo\], I won't cheat on yooooou. This'll be the only time I'll be alone with him. I'm always alone with you in bed, riiight...? But no more tying me to the bed with a collar, 'kay? Kuhhyahhahhahahahahaha...!!!"

And:

"Scary, scaary... But it's not like I mind being controlled by violence, you see? Grab onto my head! Make my face twist in pain, tear me apart like a hawk does with its talons to its prey, scratch at me and trample upon me...!! Aaah, remind me of Kinzo in his younger days once more...!! That single time in my thousand-year life! Remind me of that day I was taught the joy of being controlled, surrendering and being reduced to furniture!! Uhyaaahhyahhyahhyahhya!!"

  
I don't know, just it always felt like Kino didn't stop at the rape based on a lot of her dialogue and I find it odd that no one ever acknowledges that when talking about Kinzo's crimes.

Obviously since this was a forgery you could read everything Beatrice says about Kinzo and the basement as fictional, but it still seems odd to mention if it has no truth to it at all.

Just saw someone talk about Kinzo's crimes the other day and all this suddenly flashed in my mind again and realised I've never seen discussion about it.

I feel like not enough people talk about this
