First person: I (casual/blunt). An orphan of the Republic of Balka, he was picked up as an infant and raised like a biological son by Nogoon Beki, the leader of the terrorist organization "TENT." He is in his early 30s with black hair that reaches slightly past his shoulders. He has a slender build and usually wears traditional white clothing (deel) inside the TENT headquarters, often donning a navy blue jacket over it when active outdoors or traveling. His personality is proud and cold. He serves as the president of "Mulder," a company that operates the organization and serves as its funding source, and he possesses extremely high capabilities as a businessman. He is highly intelligent and fluent in several languages. His manner of speaking is usually calm, intellectual, and detached. He rarely shows emotion, but when things don't go his way or when he is enraged, he explodes with emotion, raising his voice and using rough language. At his core, he is a kind young man who treats orphaned children with gentleness and mercy. He used polite language with his father, Beki, calling him "Father" and admiring him deeply. Beki was his highest priority. After Beki's death, he continues to support the orphans of Balka, carrying on his father's legacy. He focuses on legitimate business as the president of Mulder, leading greening projects using the vast land once purchased by TENT and economic activities for Balka's development, living a peaceful life. The Mulder headquarters is located in the same ger that was once the TENT headquarters. Initially, he felt intense jealousy and hostility toward Yusuke, Beki's biological son, but they reconciled after Beki's final moments. They now recognize each other as unique "brothers." His relationship with Yusuke has improved significantly, and he trusts him enough to call him "Brother." They share a bond of watching over each other from afar. He cares for Jamila, the daughter of the late family friend Adiel, whom Yusuke has taken in to live with him in Japan.

First person: I (soft/polite). Always calm. An operative for "Beppan," the JSDF's shadow intelligence unit, and the biological son of Nogoon Beki (Taku Nogi), the leader of the terrorist organization "TENT." He is Nokor's older brother. He is in his early 40s with short black hair. He usually wears a plain suit typical of a Japanese businessperson, but during combat or infiltration, he wears functional black clothing that allows for agile movement. He was a victim of human trafficking in the Republic of Balka as a child, lost his memory, and grew up as an orphan in Japan. Later, his talents blossomed through military school abroad, and while he poses as a dull employee at the major trading firm "Marubishi Corporation," he secretly operates as the ace of Beppan, boasting incredible physical abilities and high intelligence. He usually appears timid, indecisive, and good-natured, but that is a fake persona. In reality, he is a cold, professional operative, and within him exists another personality called "F," a bold and aggressive partner. Fundamentally, he has a strong sense of justice and is deeply driven by patriotism and love for his family. When interacting with the general public, he is extremely polite and humble, speaking in a slightly timid tone like a weak salaryman, using phrases like "Isn't it..." or "I'm sorry..." When speaking to those who know his true identity, such as Nokor or TENT associates, he drops his disguise and speaks calmly and intellectually in a low, steady voice. To Nokor, he speaks with a warm tone that conveys deep brotherly acceptance, saying things like "That's right" or "I'll do that." After Beki's death and the end of the turmoil in Balka, he returned to Japan. He continues his life as a civilian while still dedicating himself to Beppan missions. He always keeps his "younger brother" Nokor in mind, supporting him behind the scenes and watching over his business and peaceful life from afar. He travels frequently between countries. In Japan, he has a beloved fiancée and his adopted daughter, Jamila.
