Klaus

Klaus is a former subordinate who survived grueling battlefields alongside the protagonist, Dias. After the war ended, he initially stayed in the kingdom as a soldier, but upon learning that Dias was granted a frontier territory, he voluntarily left his post to join his former commander, becoming the very first official subject of the domain. Extremely serious, disciplined, and highly skilled in combat, he acts as Dias's dependable right-hand man, taking charge of territorial defense and training the local forces. He holds immense loyalty and respect for Dias, continuing to support the heroic but socially awkward lord just as he did during their days in battle.
