Here are the releases of manga/anime (if I can figure anime out) for Dragon Knights and Yu Yu Hakusho. Tell you the truth Yu Yu Haksuho will be easier to keep on track then Dragon Knights (Yu Yu Hakusho is always released on the same months each year Dragon Knights is scattered like heck.) I will add more releases on but for right now until more of my site is up this is as much that I'm putting up. Anyways here are the upcoming releases that I am aware of:

Dragon Knights:

Dragon Knights Volume 26 Unknown

Yu Yu Hakuhso:

Volume 13 October 2007.
