Jack the Ripper

[Daemian]

I think he just mentioned him when he compared himself with The Ripper when he says that a professor wanted to investigate him using an excuse, just like they did with Jack, calling him to do surgery or something as an excuse to investigate him.

But yeah, then he mentions "Jack and his sons". Though I first thought he was referring to more manpigs, since he referred to "bringing them toys".

Yea, sometimes Mandus called the machine "Jack".
I think it was almost natural for him to call such a machine like that.
