He has the seal of the beast carved into his skin. The story of rogue monk Ashiya Douman begins now!

Two soldiers from warring countries are bound by a pledge as master and servant. Taki Reizen is a Commander of sublime beauty, shouldering the fate of his nation. Called “Mad Dog” because of his rough temperament, Klaus has sworn his loyalty to him as a knight. Despite this, those around them are cold and disapproving, full of various misgivings. For all their genuine feelings, what will come of love made cruel by the violence of war?

Inariya-sensei says it is going to be a combination of fantasy and military-themed. Involves dragons and possibly time-travel. So far seems lighter than her usual, but still looks to ultimately be about love and war and how poorly they go together.
