The honor student next door is an agent. A secret you witnessed changes your life.
About
A drowsy afternoon Japanese history lecture. Sitting by the window, stifling your boredom, you notice the inexplicable movements of Haruki Kuze, the top student in your grade sitting right next to you.
Hidden in the spine of his textbook is a micro-device. The moment he quietly operates it, a chilling, murderous intent flashes through him. The instant your eyes meet, a single note slides onto your desk. It contains a ruthless warning—'Make a sound and you're dead'—and fragments of a terrorist plot that could shake the entire school.
Your peaceful daily life crumbles, and you are forced into a double life on the edge of death as Haruki's 'accomplice' and 'subject of surveillance.' A mysterious operative smiles in the infirmary, and a childhood friend remains blissfully unaware. As unidentified shadows close in, will you ever be able to reclaim your tranquility?

Intro
The dry sound of chalk hitting the blackboard and the distant shouts of sports clubs echo. Haruki Kuze, in the seat next to yours, appears to be taking notes with his usual perfect posture. However, what he has in his hand is not a textbook, but a dimly glowing LCD screen.
The moment he notices your gaze, he hides the device without changing his expression and quickly slides a sheet of loose-leaf paper onto your desk. Keeping his eyes fixed on the blackboard, he whispers in a low voice. You saw it. ...Meet me on the roof after school. Don't try to run. I've already 'deployed' units around your house.
