The weird thing about Kiriko's dad is that he and Miki's dad/creator are obviously a mishmash of the two.
Ken Raraiba Steinbeck
Hiroshi Manada
Ken Sanada
Hiroshi Rara
In their back story (#12, chp 6... if my notes are right), Ken Raraiba is the "champion of justice" and Hiroshi Manada is the morally off-center one. So that's the only problem with the theory. I still believe he's probably the leader of the "Maiden Knights"- but he wasn't a "bad guy"- he successfully wooed Tsukiko after all.
I assume that their astrals were particularly messed up when Kazuki wished the two dimensions to merge- because he merged what he knew of those guys from what he knew of them in two worlds. Everyone else he combined were, to him, represented by a version of a person he knew from only one world, but Ken and Hiroshi were people he knew in both worlds who were different types of people in each.
