Manager of the Energy Development Division at Marubishi Corporation. At first glance, he appears to be a timid, unremarkable salaryman, but he actually harbors a second personality named "F." He is an elite member of "Beppan," the JSDF's secret intelligence unit, possessing extraordinary physical abilities and cold, analytical judgment.

Nogi's colleague and a supportive friend. However, it is later revealed that he is actually a "monitor" (mole) for TENT who orchestrated the erroneous wire transfer at Marubishi Corporation.

A Superintendent in the 4th Foreign Affairs Division of the Tokyo Metropolitan Police Public Security Bureau. He teams up with Nogi after rescuing him in the Balkan Republic. With sharp insight and relentless persistence, he closes in on Nogi's true identity and the truth behind the terrorist organization TENT.

A highly capable agent living in the Balkan Republic and an ally to Nozaki. While he understands Japanese, he cannot speak it, so he communicates using a voice translation app on his smartphone. He is extremely competent and a beloved character.

A Japanese doctor working for the World Medical Organization (WHI) in the Balkan Republic. She becomes a fugitive alongside Nogi and Nozaki, pursued by the Balkan police, and survives a grueling escape. After returning to Japan, she forms a deep bond with Nogi.

A genius white-hat hacker belonging to the Cybercrime Division of the Tokyo Metropolitan Police. He appears as a brilliant ally to Nozaki. He infiltrated Marubishi Corporation's systems and restored the tampered remittance program in just a few minutes. Through Tojo's miraculous work, evidence was found that "10 million dollars" had been rewritten to "100 million dollars," confirming the presence of a traitor (monitor) within the company.

First Half: He stood as a terrifying enemy, relentlessly pursuing Nogi and Nozaki beyond the limits of the law after they were suspected of the bombing. Second Half: In a complete reversal, he enters a cooperative relationship with Nozaki and his team, becoming a most reliable ally who saves them from crises with his overwhelming competence.

Public Face: President of GFL (an infrastructure development company) in the Balkan Republic, a partner company to Marubishi. He was the recipient of the erroneous transfer and the first person Nogi went to negotiate with to recover the 100 million dollars. He acted like a perfect gentleman and a friend to Japan. Secret Face: A top executive of the terrorist organization TENT. He is the executive in charge of Japan for TENT, which has roots all over the world. He was the one who defrauded Marubishi of the 100 million dollars, converting the money into diamonds to fund TENT. Shocking Scene: Nogi (Beppan) took his family hostage and made Ali experience extreme terror by staging a trick where his family appeared to be executed before his eyes. In despair, Ali confessed that the leader of TENT is a man named "Nogoon Beki."

Public Face: Known as the "Green Magician" who saves orphans in the Balkan Republic. In the local language, "Nogoon" means green and "Beki" means leader. He succeeded in a desert regreening project and saved many orphans who lost their parents in the civil war, earning him the status of a "god" among the local people. Secret Face: Leader of TENT, a terrorist organization that shocks the world. Behind the scenes, he leads TENT in carrying out assassinations and kidnappings. However, his goal is not world destruction, but raising funds to support the orphans and achieving a certain massive objective. Shocking Identity: He is the biological father of the protagonist, Yusuke Nogi. Formerly a Japanese police officer (Public Security), he was caught in a civil war while on a top-secret mission in the Balkans. Abandoned by the Japanese government, he lost his wife in the conflict. This desire for revenge led to the birth of TENT.
