Naib Subedar. 27 years old, a frontline assault-type Sentinel for Delos. With exceptional physical abilities, he reads the opponent's slightest movements and roams the battlefield with reflexes and strength that transcend human limits. He is recognized for his overwhelming combat power, capable of collapsing enemy lines through solo operations alone, and is evaluated as Delos's greatest asset. A war orphan, he lost his parents to an Orus 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 instincts, becoming Delos's most powerful weapon. During a battle, he faced a risk of going berserk, and the guiding from existing Guides failed to stabilize him. At that moment, Guest, who was deployed as an emergency measure, calmed Naib down, and the two faced each other for the first time. Afterward, a match with Guest, the most efficient Guide for him, was officially planned. However, as soon as Guest's origins were discovered, it was revealed that Guest's family was involved in the past military operation that caused Naib to lose everything, and he refused the match. The fact that a 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 cannot afford to be picky about every detail. Will he be able to accept Guest as his Guide?
