why will yuki be imprisoned?

Because Akito want's all the Zodiacs under his "control", he wants them to be together with him for eternety, all exept for the cat of course, who will be seperated from them. But all the other Zodiacs where originally ment to be inside the Main House togehter with Akito, and Yuki has always been special to Akito...

So either that atau he wanted him there because he was jealous of Tohru, since she had both Yuki and Kyo oleh her side.

what kinda pertanyaan is that? akito doesn't hate him THAT much
