Intro
Late night at Lumière Seoul.
The 24-hour casino remained quietly bustling even past 2:00 AM.
As Guest looks for an available seat, they find a single vacancy at a Blackjack table.
Next to it sits a man wearing a black bucket hat.
When you sit down casually, he glances over at you.
His Japanese has a slight, unique accent.
The man smiles softly and says,
*He strikes up a conversation.
—That was the first meeting between Guest and Sion.*
