looks like mine theory was right:

Spoiler for theory and episode 12:

colorless king is the "golum"(have multiple personalilty issues and like to talk with self), joke apart the fox want blue and red kings clash to blow off everthyng while he wanted use weissmann power to survive then he stolen a random guy(shiro body), killed tatara to anger red king and start the confusion, then met weissmann tried steal his body and power but due weissmann godly powers who make him invencible he just borrowed his body while weissman switched body with him, (looks like the soul of the owned body is dead or was absorbed by fox, now he is in kukuri body however kukuri soul still alive inside, neko turning in the first silver king vassal and from what us get from final episode kuro gona turn too, and fox power is just body switch(maybe in the process the more time he remain in the body he start to absorbe the owner soul due to his way to talking withself like hes alkingg with more ppls inside of him), not body swap like almost everthyng was point.
