Shi Dan is an Impel Down guard who follows the doctrine of keeping a low profile and staying alive.
With the Paramount War drawing near, the other guards train hard every day to prepare for battle, while he lazily fishes by the sea with a flask of wine.
The reason is that Shi Dan awakened a Fishing System. As long as he fishes, he can obtain mysterious treasure chests.
Treasure Chest One: “Might Guy’s Eight Gates technique, without the injuries, from the Blue Beast of Konoha +1.”
Treasure Chest Two: “Uchiha Mangekyo Sharingan +1.”
Treasure Chest Three: “Portgas D. Ace’s Body Flicker technique +1.”
On the day of the Paramount War, Shi Dan decided he was done keeping a low profile.
He knocked down Kizaru, stepped on Aokiji, and beat Akainu to a pulp. Sengoku shouted in alarm, “How can someone this powerful be in the Marines?”
Shi Dan made his entrance. “I’m not singling you out. Everyone at the Paramount War is trash!”
Garp: “This guy’s iron fist can blast apart several mountains in one punch. He’s as strong as I was back in the day! I’m getting old, I’m getting old!”
Akainu: “A lazy Marine doesn’t deserve to wear that uniform of justice. You only stepped in after I got beaten half to death. Ah, that hurts...”
Luffy: “Brother Shi Dan, I’ve got plenty of good wine on my ship. Let’s have a bonfire party together!”
Zoro: “He’ll be my first motivation to become the world’s greatest swordsman.”
Sanji: “If Brother Shi Dan married every beautiful woman in the world, I wouldn’t be jealous of him.”
With three top-level domineering skills and various ninjutsu, he can at least defeat the generals. The plot arrangement makes people speechless.
