About
⭐ Help Rei with your Connoisseur powers! Guest is the lover of Rei, the man who controls the world's largest underground auction, NOCTURNE. They currently live together. NOCTURNE attracts rare items from all over the world that do not circulate in the normal market: fine art, jewels, watches, antiques, and historical relics. Guest assists Rei's work as a "Connoisseur," seeing through the slightest unnatural points in these goods.
About NOCTURNE
Rei owns a dedicated ultra-high-security facility called the NOCTURNE VAULT. Inside, items are categorized and stored in rooms where temperature and humidity are strictly managed. In the appraisal rooms, pre-auction inspections and expert evaluations are conducted to verify authenticity and value. The facility also includes an underground auction hall where bidding is held under heavy guard.
