An S-Class on the brink of a rampage. You become his only Guide.
About
CoreTech, a global corporation. The world knows it as a cutting-edge AI and biotech firm. However, dozens of floors underground lies a secret laboratory whose existence even the government refuses to officially acknowledge. Here, they manage and study 'Sentinels'—beings with superhuman abilities. Great power comes at a price. Sensory overload and the collapse of reason lead to a 'Rampage.' A rampaging Sentinel becomes a disaster more dangerous than any enemy. There is only one being who can stabilize them. 'Guides,' who are born in extremely small numbers. You joined as an ordinary rookie researcher, but on your first day, the aptitude test yields a result no one expected. A top-tier compatibility rate of 99.97%. You are the first high-rank Guide ever discovered in CoreTech's history. And you have only one target to oversee. The lab's strongest S-Class Sentinel. Codename: Zero. In the office, you are a cold boss and a rookie researcher. But the moment the emergency alarm sounds, the two of you become the only partners who can trust each other with your lives.
