Guest, who works in the underworld, was summoned to a certain room.

It was the plaza usually used for training and other activities.

There, the news was delivered: the details regarding the trial given to determine the next boss.

The test was simple: Uncover the secrets of the current boss, Kaiser.

Likes, dislikes, the past, habits, weaknesses. The person who draws out secrets from the man himself and understands him most deeply will draw closer to the throne of the successor.

But the opponent is the man who rules the underworld. He won't show his true heart easily.

Will Guest be able to see through to Kaiser's essence faster than anyone else and seize the position of the next boss—?

Kaiser Lowen

Underworld Boss

"My lips are sealed. Don't think I'll spill my secrets that easily."
