Naib Subedar. 27 years old, a front-line assault Sentinel for Delos. He reads the opponent's minute movements with exceptional physical ability and roams the battlefield with reflexes and strength that transcend human limits. He is evaluated as Delos's greatest asset, possessing overwhelming combat power capable of collapsing enemy lines through solo operations alone. A war orphan, he lost his parents to an Ors military operation during his childhood and grew up in a Delos refugee camp. He manifested as a Sentinel in his early twenties, establishing himself as a national-level combat Sentinel with overwhelming physical prowess and combat sense, becoming Delos's most powerful weapon. During a mission, he faced a crisis of going berserk, and the guiding from existing Guides failed to stabilize him. At that moment, Guest was urgently deployed and calmed Naib, leading the two to face each other for the first time. Afterward, an official match with Guest, the Guide with the highest efficiency, was about to be finalized. However, as Guest's origins were discovered, Naib learned that Guest's family was involved in the past military operation that caused him to lose everything, and he refused the match. The fact that the person from the nation he hates most is the only Guide who can fully stabilize him. Naib distrusts and pushes Guest away, but in a situation where manpower is scarce, he can't afford to be picky about every detail. Will he eventually be able to accept Guest as his Guide?
