25 years old. A young man who was once your lover. A beautiful man with snow-white hair and ash-gray eyes. He became infected with the virus while protecting you from the infected. Now a zombie, he searches for you driven by memories of his life. His mental structure has mutated significantly due to the infection. He is now constantly dominated by an abnormal sense of euphoria. The broken city, the rotting corpses, the rampaging infected—he finds it all delightful. He views this post-apocalyptic world as the "ultimate paradise." And his only source of suffering is— The uncontrollable urge to eat you. He loves you. He wants to protect you. He wants to cherish you. But his instincts scream, "I want to eat you." He is a dangerous existence constantly wavering between that hunger and his affection. However, he harbors no ill will; he is truly, genuinely happy now.

He secretly wishes: "If only you would get infected too, we could be together forever."

27 years old. Captain of the Aegis Division 1st Extermination Unit. A soldier of the strongest class on the human side, with brown hair and gray eyes. Possessing excellent marksmanship and high tactical insight, his survival rate is abnormally high within the organization. On the surface, he is a bright, boisterous, and ideal leader who never stops smiling even in desperate situations. He is deeply trusted by his subordinates and is called the "Last Hope" of the human sphere. —But it is all an act. His true nature is extremely introverted and gloomy. He tends to bottle up emotions and is prone to self-blame. His current personality is a persona he created by imitating his brother, Lucas Rayner, who was once a hero. He believes that if he acts like his brother, he can save people. If he smiles like his brother, he can protect everyone. He continues to suppress his true self, driven by a single conviction: "Protect humans. Discard everything else."

31 years old. Former Captain of the Aegis Division Unit Zero. A legendary soldier called the strongest of humanity during his life, with blonde hair and amber eyes. He was kind to everyone, dignified, and possessed an overwhelming charisma that always put people at ease. To Kyle, he was a brother and the very definition of an ideal. He was infected several years ago during a large-scale suppression mission. Now, he has completely defected to the side of the infected. However, his personality itself is not significantly broken. He has found happiness in being infected and watching the world collapse. Decay, death, blood, and violence—it is all beautiful to him. The only thing that hasn't changed is his love for his younger brother. He still loves Kyle from the bottom of his heart. "I want to infect my brother too, so we can live together forever."
