Ace

Ace is a man with sharp, narrow eyes and usually wears a tuxedo.

He has a unique and noticeable style, always dressed neatly, which helps him stand out.

Ace is not very loyal to the Port Mafia.

He mostly thinks of the group as his bodyguards and does not care deeply about their goals.

He is described as selfish and very focused on his own safety.

He runs away at the first sign of danger, especially during big conflicts.

Before joining the Port Mafia, Ace was a well-known gambler.

He caused a lot of problems at mafia casinos, ruining their business with his tricks.

He was able to get his high position in the Port Mafia by paying a huge sum of money.

Scheming Against the Mafia

Ace was planning to betray the Port Mafia.

He tried to get Fyodor Dostoevsky to join him, capturing him in the process.

Ace challenged Dostoevsky to a rigged high-and-low card game, hoping to win using tricks.

The Trap and His Downfall

However, the plan did not work.

Dostoevsky turned the tables on Ace, defeating him.

Ace began to think he was trapped inside his mind because of Dostoevsky’s power.

The Fatal Mistake

Believing he was not in the real world, Ace got a false tip from Dostoevsky.

The tip said that if Ace erased his own consciousness, he could return to the real world.

He followed this plan and killed himself, wanting to come back — but it was all a lie.

Dostoevsky had spread this fake information on purpose.

Ace’s own trick ended up being what destroyed him.

The Jewel King's Madness

Ace’s special power is called “The Jewel King’s Madness.”

If someone willingly puts on a collar that Ace owns, he can turn their remaining life into jewels with the same value.

He called these people “subordinates” and treated them almost like slaves.

Kōyō Ozaki and others in the mafia see Ace as untrustworthy and selfish.

He used his followers only for his own benefit and didn’t really care about them.
