I know that this might come out of completely nowhere, but given recent leaks and discoveries, I just had this thought - we know that Kenny is, probably, much older than Sukuna. So, here's an idea of how to make this family tree even more fucked than it is - what if Kenny tried having sorcerer babies but Sukuna happened and she went, "Man what a lame piece of shit I was actually looking forward to the other one" and threw him off. But then mfk hunts down the soul of their dead son, and then bangs their reincarnation to birth Yuji so that he would beat Sukuna's ass (mind you, none of that has to do with merger, it's just Kenny shenanigans)

Like, at this point, Kenny strikes me as a person who would just go "Man, I wonder what it feels like to be raped" out of boredom so, like...I can see it, sorta? Man what a freak - imagine Kenny just sitting down before they do Tengen in and going, "but first, lemme tell you about all the dicks I sucked over these years, you won't believe the kind of shit I got up to sis"
