It's cute, but isn't the trait connection tag kinda spoilerly? Since I think the trait is the "Case 3 murder that was having character development"
The trait connection is that the both of them have foul mouths (although in Tenko's case it's only against males). But of course, that too. Just when we think they (don't forget Ishimaru) might have a bit of character development later on, they get killed in chapter 3.
