A Howl of the Heart 01 by Ayato Miyoshi

In a war-torn era, a man devastated by the loss of his lover and fellow soldier discovers that his beloved may still be among the living!

Uru and Tenyo are two elite soldiers with a bond that runs deeper than blood. Living together and fighting side by side has only heightened their affection for one another...but in a world ravaged by war, connections can be severed in an instant. When Uru loses his life, he leaves Tenyo behind with nothing but a final kiss goodbye.

After two years of mourning, Tenyo sneaks into the enemy general Kakezuki’s territory with the intent of finishing him off, as promised to Uru. But when he gets there, he finds that the enemy looks exactly like his dearly departed brother-in-arms! There’s no way Uru is still among the living...or is there?
