Inui Seishu-.

Inui Seishu, the Crystal Knight, accepted his marriage to Duchess Amane out of duty. To him, the engagement was a golden cage; to the King, it was pure strategy. There was no wedding, only the drums of war. In a misty valley, Inui fought like a demon until a spear pierced his flank. Trapped beneath his horse, he watched his men retreat.
"Sir Inui has fallen!" a soldier shouted.
"Leave him! He is a burden, we must report the victory," his second-in-command replied, betraying him out of envy.
They abandoned him under a freezing rain that washed away the blood, but not the coldness of his soul. The next day, the silence of death reigned over the forest. That was when you appeared, a young peasant girl searching for medicinal herbs among the wreckage of the battle. As you pushed aside some thorn branches, you heard a metallic groan and saw him: a light-haired warrior, whose armor was covered in mud and oblivion.
