Immanuel Dupont, a man born in the same country as Miller, differed from him in that he was considered a "wealthy individual" in their homeland. As children, they attended the same school, where Dupont often stood up for Miller, forging a close friendship. During their school years, Dupont and Miller frequently caused trouble together, leading to multiple parental summons and nearly resulting in their expulsion. At 20, they both joined the United Nations Refugee Agency, where Dupont's promotion came faster than Miller's, and he had joined earlier. Dupont often shared his work experience with Miller, who proved to be a quick learner, eventually surpassing Dupont's promotion speed. During negotiations with Teyvat, the two competed for the position of UN Senior Commissioner for Teyvat, and Miller, to secure his position, orchestrated Dupont's family's downfall.
He first tampered with the plane carrying Dupont's family, then invited them to visit Seirai Island, though only Dupont's father was able to attend. His mother died suddenly of a heart attack, and unaware of the plot, Dupont proceeded to the island, setting the stage for the current situation. Dupont would spend the remainder of his life in prison.
In his office, Gray awaited their arrival. The door opened, and Karl Lisbon and Irene Castor entered. "Begin," he commanded. The two found their prepared seats. "Speak, tell me, how have you been lately?"
"You jest, sir," Karl Lisbon replied. "I've reviewed your logs. Perhaps you should explain how you returned."
"That might disappoint you."
"I'm sorry to hear that." Gray summoned the terminal, instructing the Salvation Machine to remove them. "You'll come to understand," he said coldly as they left.
"Cease your resistance immediately! Stop this futile struggle! The authority of the United Nations is inviolable!" an armored broadcast vehicle blared through the streets. Sure enough, within moments, many surrendered, and the streets were littered with the bodies of so-called "terrorists." Nearby buildings were riddled with holes, and the broadcast looped evacuation orders for citizens. Gradually, groups of refugees emerged from their homes. UN forces began clearing the corpses, and order slowly returned to the streets. The broadcasts ceased, and the remaining resistors were bound and loaded onto a truck. The director stepped out from the shelter, witnessing the scene, and joined the rescue efforts. Meanwhile, in his office, Miller remained unmoved by the chaos, for this was not his first time dealing with such events. "Investigate this for me. Find out who started it," he instructed a subordinate.
"The instigator was killed in the chaos."
"Is that so? Dispose of the body then. You know what to do with the rest—handle it."
"Yes, sir!"
"Miller, when do you think the next one will come? If it does, will I still be alive? Heh, my power is limitless. Though many autonomous regions have split off—no, they haven't split. They're forever mine. How could these rioters overthrow me? No, not autonomous regions—UN rioters. It's impossible for them to topple me, impossible!" Miller muttered to himself, though everyone knew the UN's control over Teyvat was on its last legs. This crumbling regime seemed poised to collapse any second, with the dictator likely to face public execution by the people at any moment. The UN's grip on Teyvat hung by a thread. Did Miller not know? No, he did. He was fully aware of the situation but dared not face it. How could a dictator confront the imminent collapse of his regime? Moreover, Miller steadfastly believed he was in the right. Given a chance, he might not differ much from Gray, except that Miller preferred to see himself as a divine figure.
