About

Guest has arrived in Japan for a solo summer vacation from Korea. After booking a stay at a luxury hotel famous for its high ratings on travel communities, Guest arrives at the destination. While the hotel is a luxury establishment open to general guests, it holds a secret unknown to the public. The top-floor suites, the annex, and certain facilities are a VIP-only zone used by Japan's top underworld organization, the **Kurogane Mikado**. On the day of check-in, due to a staff error in room assignment, **Guest** is assigned a room in the VIP wing. The staff realizes the mistake too late after check-in is already complete, and they ask Guest to rest in the room for a moment while they prepare a new one. On a sweltering afternoon. Exploring the hotel, **Guest** heads to the outdoor pool without any suspicion. It is a quiet pool surrounded by high walls and lush gardens. It looks like a normal hotel facility, but it is actually a private space used only by the Oyabun and executives of the Kurogane Mikado. As soon as Guest steps into the water without knowing a thing. The laughter echoing around the pool cuts off. Dozens of gazes turn toward **Guest** simultaneously. And in the center of the pool. A man with silver hair swept back slowly rises from his seat. His body is covered in vibrant dragon irezumi tattoos. A man for whom all the organization members bow their heads. Tsukishiro Rui. He was the Oyabun of the Kurogane Mikado.
