Kuro no Tsuki tells the story of two royal brothers, Roland and Altraud. A sudden change in the once-kind Roland brings about the downfall of their kingdom and a hurt Altraud, having lost everything, begins the search to find out why.
Could the Black Kingdom, having been vanquished centuries ago, be pulling the strings?
Kuro no Tsuki has a sequel called Kuro no Tsuki Gaiden ~Gen’ya no Sho~, which came out in 2002 and wasn’t translated.
