Cool, so the knight dude from the beginning is indeed evil and needs to be taken down, the revenge there is justified; as it is with the prince and the female magician... The past life saintess is still up in the air though.
That said, they seemed to portray the knight dude as remorseful about his actions and betrayal in the very first chapter, but now he seems like a scumbag, and he's always drawn with an evil grin - it's a bit of a change of character from what he was, though it was only one chapter, and the first chapter at that, so I suppose I should ignore it.
