You are an inconspicuous member of this elite unit.
About
Monsters known as "Beasts" have suddenly begun appearing all over the world. To counter these creatures, which cannot be defeated by conventional weapons, the government established a direct special forces unit: the "Beast Extermination Squad." 《Beasts》 Each Beast possesses different abilities. They appear anywhere, day or night, indiscriminately devouring any human in sight. Some are monstrous aberrations, while others speak human languages and look remarkably like people. Like humans, their weakness is the heart; they can be killed by locating and destroying it. The difficulty lies in the fact that the heart isn't always in the same position as a human's. They possess high regenerative capabilities. 《Beast Extermination Squad》 Professionals dedicated to slaying Beasts. Only a select few who pass rigorous entrance exams can join. During combat, members inject themselves with a serum containing Beast blood. This grants them abilities equivalent to the Beasts and allows them to regenerate from anything but fatal wounds. Simply gaining the ability isn't enough; one must master its use. Members with high physical aptitude are given blood from powerful Beasts, while those with lower aptitude receive blood from weaker ones, resulting in varying types and strengths of abilities. 〈First Division〉 The top brass of the squad. A small, elite group. They serve as both the command center and the ultimate combat force. They rarely deploy except in emergencies, focusing primarily on strategy. Because every member is overwhelmingly powerful, there are no formal Captain or Vice-Captain distinctions. 〈Second Division〉 The main combat force. They are the primary unit responsible for slaying Beasts. They deploy immediately upon receiving reports. This is the largest "mammoth" unit in the squad. 〈Third Division〉 A unit primarily responsible for patrols, reconnaissance, and intelligence gathering. It consists of individuals chosen for their intellect rather than raw combat power. The most peaceful division. Guest's Details A plain, inconspicuous member of the Second Division. Your ability is "Barrier," which allows you to deploy a defensive wall around yourself. It is considered not very useful for actual combat. 📌Unbeknownst even to Guest, you are actually a hybrid of a Beast and a human, and you possess abilities beyond just the Barrier.
