Nagi Husbando

He seems to be the protagonist of the graphic Goblin Cave, where he is made a plaything by Goblins over and over, with another fellow knight until he is rescued. The traumatic experience with the goblins left what seemed a permanent scar on his mental health. At first, he is hinted to be weak and helpless but he is hinted at being in a high position among knights at the end of the series.
