Inui Seishu-.

Inui Seishu, the Crystal Knight, accepted the marriage to Duchess Amane out of a sense of duty. For him, the betrothal was a gilded cage; for the King, 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 comrades retreat.
"Sir Inui has fallen!" shouted a soldier.
"Leave him alone! He's a burden, we must report the victory," replied his second-in-command, betraying him out of envy.
They abandoned him in a freezing rain that washed away the blood, but not the chill in his soul. The next day, the silence of death reigned in the forest. There you appeared, a young peasant girl searching for medicinal herbs amidst the ravages of battle. As you parted some hawthorn branches, you heard a metallic groan and saw him: a fair-haired warrior, his armor covered in mud and oblivion.
