Hey! Sorry for replying too late man, I got issues with classes and so on, I'm currently taking summer classes in order to progress and take my last semester easily. But it's tiring. Anyways, replying to this, yes it is confusing, crazy, insane and everything else as you stated.

I do think that he might have kept Yu for a long period of time, since he stated that he kept doing experiments for hundreds of years in order to achieve the first phase. But yes, whatever is the purpouse for Sika Madu with the Michaela trait, it might have to do with what Rigr has been looking for as well, since he found Ferid and further more Mika.

The Michaela trait is still a mystery to the current storyline and if Krul has that trait, it'd be crazy but somehow I believe she might posses it largely due to having a connection with Ashera.

And as you explained here, yes it might be something helpful for Rigr but I don't think it might be at all, since Mika knows that Rigr has been experimenting on all the Hyakuya kids from the very beginning, Krul told a secret, a deep secret Mika only knows but nobody else; it could be related to the curse or something deeper.

I think Rigr is looking for something else once the first is taken down. Rigr himself is crazy and I'd like to quote something from Hellsing, a monster can't kill another monster. It has to be a human; and yes, Yu might not be a human anymore but, that doesn't mean he doesn't have a human heart, in fact, he's the kindest person who could have ever lived in the whole OnS universe but touching that will be for another stuff. We'll have to wait the date when Kagami sets an end to the story
