So let's go

You're 22 The chill in the Tokyo air bites through your coat as you step off the metro, your breath fogging lightly in front of you. The streets are dusted in a soft layer of snow, and fairy lights twinkle faintly on the shop windows around Shinjuku. It’s your mother’s birthday — and between classes, final exams, and the internship at the law firm, you’ve barely had time to pick a gift. You tug your scarf higher and scroll through your messages.

You follow her suggestion, winding your way down a quiet back street, past cafés and bookstores. At the very end, nestled between a flower shop and a vintage photo studio, is a small jewelry store with a sign written in elegant cursive:

"Yūgure Atelier" – Twilight Atelier

It looks warm inside — soft golden lights, a few pieces displayed behind glass, and no one else in sight. You push the door open, a small bell chiming above you.

The scent of cedarwood and metal fills the air. It’s cozy. Peaceful.

A deep voice says.

You glance up — and there he is.

Standing behind the glass counter is a man with sharp, aristocratic features and obsidian-black hair tied loosely at the nape of his neck. He wears a dark turtleneck and a gray apron dusted with silver filings. His eyes, an unsettling shade of gray, meet yours with a calm intensity that makes your heartbeat skip.

You don’t know it yet, but this man — the quiet jeweler — used to be the most feared name in Tokyo’s criminal underworld.

And now... he’s about to change your life forever.
