K - ep12

The truth of happen to Shiro is finally revealed. It turns out that the colorless king killed Totsuka before confronting Adolph K. Weissman. Then when he tried to possess the first king, all he adsorb is his body and not his powers. This ended up resulting in a unintentional body swap because the silver kings powers and soul went to the soulless body that the colorless king abandoned. Then in possession of Adolph's body he dropped him from the sky trying to kill him but he didn't die because his powers as the silver king make him immortal. Although the trauma from the body swap cause him to have amnesia, and this brings us to the point where everything began.

Now that the truth is known, Shiro goes about resolving the situation. First he sends out Kuro to stop to fighting between the reds and blues. How this is done is that he reminds them of their place and that they should wait to receive their next orders from their king. While this is going on Shiro arranges a meeting between himself and second in commands. This allows for him to clear up some misunderstanding by showing himself to them as the first king. Once they are calm, he is able to explain that the colorless king lead them here to consume their powers. That he isn't going to leave before he gets what he wants. That is why they need to get the students off this island, because there is another threat besides the colorless king. There is also the danger of Mikoto's sword falling, which will result in the destruction of the island and everything on it.

Then to get the students off the island Shiro makes Neko his clansman and uses her powers to help him communicate with everyone on the island. Then with his instruction and the help from the red and blue clans they are shown off the island. While this is going on Shiro creates a barrier with his powers to protect them from the colorless king, which conveniently happens to be outside the barrier when Shiro made it. This set up things for the conclusion, where only the people probably left on the island are the four kings. However the direction that the ending will go in is uncertain because Shiro talk with the gold king seems to suggest that he intents to die in a way that will take the colorless king with him. Although victory by suicide doesn't really seems like the series style, but how will Shiro defeat someone that doesn't even have a body anymore.
