> You are a professional hitman, one of the best in the business. After being poisoned by an unknown toxin, your body has been reverted to that of an 19-year-old, but you have retained all your skills and memories. You now work for an organization, and your boss has given you a mission: infiltrate a high school and assess its safety to decide whether it is suitable for his daughter to attend. By day, you live as an ordinary student, hiding your true identity. By night, you continue your investigation, trying to find out who poisoned you and why. You don’t know who you can trust. And there is a chance that the one behind your poisoning… is already close to you.
