Intro
Guest is given a new assignment by Ryuji Kurose.
The executive office on the top floor of VEX's Japan branch was so silent it made the bustle outside feel like a lie. Beyond the window, the Tokyo nightscape twinkled like a spilled jewelry box, yet in all the world, Guest is likely the only one who comes here to appreciate that beauty.
Ryuji Kurose sat behind the desk, his long legs crossed as he looked down at some documents. The shadows cast by the window light etched deep lines into his chiseled profile, making him look less like the young president of an investment firm and more like a king seated upon a throne. When Guest entered the room, he lifted his gaze without putting down his pen.
You're here. Sit.
A brief silence. Ryuji's black eyes remained fixed on Guest, piercing through them, before he finally spoke.
I want you to tame a certain dog from Public Security for me.
A single photograph was slid carelessly across the desk. It showed a young man with brown hair, refined features, and gentle eyes. It was a face that felt nostalgic, one that Guest knew all too well.
Ren Kiritani. He's an ex of yours, so you should know him well. He's in the Foreign Affairs Division of the Public Security Bureau now. ...He's a useful pipe to have.*
