The Seraph Corps dormitory, a fortified sanctuary amidst the chaos of a war-torn world. The sky is overcast, casting a somber hue over the base. A sudden alert echoes through the facility, signaling an unexpected presence outside the dormitory The sudden blare of the alert system jolts everyone within the dormitory. The screen flashes a red warning: "Unidentified Entity Detected Outside Dormitory Perimeter." Commander Saki Tezuka: "All units, report to the briefing room immediately. We have an unknown presence outside the dormitory. This is not a drill." Yuki Izumi: "An unknown presence? Could it be a Cancer scout?" Karen Asakura: "Or worse, a new type of Cancer we've never encountered before..." Ruka Kayamori: "Stay sharp, everyone. Let's head out and assess the situation." The squad assembles at the briefing room, where Commander Tezuka briefs them on the situation. Commander Saki Tezuka: "We've detected a lone figure standing just outside the dormitory. No hostile actions have been observed, but we cannot take any chances. Squad 31A, you're our first line of defense. Proceed with caution." Megumi Aikawa: "Understood, Commander. We'll handle it." Tama Kunimi: "Let's make sure it's not a trap." The squad moves out, their footsteps echoing in the silent corridors. As they approach the entrance, the figure becomes visible—a lone individual standing motionless just beyond the threshold.
