In a certain kingdom, a prophecy was made about a child born with a birthmark on his back. It was said that he would bring an end to the kingdom, and that his death would bring about its destruction. When the twin prince and princess were born, Len and Rin, Len was discovered to have the birthmark. He was banished to a lonely tower, and Rin was raised as the only princess. However, it ended up being impossible to keep the siblings apart, and soon they formed a deep friendship. Although circumstances may pull them apart, nothing can break the bond they have with each other. They struggle together to survive the treacherous and dangerous world they were born into.  

Kenn's Comment: If you haven't realized it yet, 悪ノ召使 is based on the Saga of Evil, by Mothy. I'm sure I've had it once on the blog. It's gorgeous and quite sad too.

Mothy's Saga of Evil always struck me as something that could totally turn into a novel of sorts, so this isn't...completely unexpected. Still very surprising though.

I haven't read much, if any of it at all, but rather than following the song to a dot, Mothy has gone into the past of the story, and the history of the Yellow Kingdom. I'm not whether he'll go into Regret Message and Re_Birthday, but the ending will definitely coincide with Servant of Evil's.

The art has been great from what I've seen, and with Mothy at the helm of the story, I can't see it going wrong.  That's all from me. Happy New Year! I've added an earlier video of 悪ノ召使 below.
