Jinbe was confused and astonished by what Ken meant by that, but he followed him nonetheless. Soon, Ken was standing in front of another prison cell. This one was not far away. Without any thought, he destroyed the cell locks and entered.
"Hahahaha... Have you come to free me too?" a voice in utter darkness said, laughing loudly. Unlike the other prisoners, this one was special. He wasn't wearing the prison dress but the actual warden's dress of Impel Down.
This was Shiryu of the Rain, the previous warden of Impel Down, who had a penchant for killing people and was bloodthirsty.
"Shiryu... I am sorry," Ken said, and in the next moment, he swung his hammer. The hammer was fast and precise, going straight for Shiryu's head. He didn't even get time to dodge. Mjolnir blasted through his head like a huge bullet, and the grey matter splattered on the wall behind as if someone had thrown a bucket of red paint.
Shiryu couldn't die more after this. Jinbe, who was outside the cell and curious, shuddered a bit. He thought Shiryu was some kind of friend of Ken, but it was nothing like that. After retrieving his Mjolnir, Ken came out of the cell. The others who were expecting Shiryu to come out had gone dead silent, as some had heard and seen what just transpired.
The feared ex-Warden of Impel Down was dead. He didn't even get a chance to say something in his last moments and was actively thinking that Ken would free him, just as he did with Jinbe.
"Why... why did you kill him?" Jinbe couldn't help but ask. He wasn't a saint, so he didn't care about the other criminals, but he was curious and thought Ken might have some enmity.
"It's because they are the worst criminals and have ties with Blackbeard. Need I say more?" Ken said. Jinbe squinted his eyes and nodded. Now he perfectly understood. Ken didn't stop with Shiryu and proceeded to other prison cells.
The second one was Avalo Pizarro, the one who ate the Isle-Isle fruit (Shima Shima no Mi). This effectively could make him assimilate into an island and control the things around after assimilation on the island, but of course, all of this didn't matter as he was tied down by Sea Stone.
"What... What are you doing?" Avalo, with his sharp teeth, shouted at Ken when he saw him entering and rotating his hammer. He had already seen from nearby how Ken killed Shiryu, and he was sure that he had never met this guy before, so he was definitely not a friend.
If you spot this tale on Amazon, know that it has been stolen. Report the violation.
"Killing you," Ken said with a smile.
"No... No... I didn't do anything to you. Why are you doing this?" Avalo pleaded. He had quite a funny face when Ken had seen him before, but now his face only held fear and trepidation.
"You haven't, and that is true, but you have committed too many crimes to be left alive. Plus, this isn't something personal. I am doing this for the safety of the sea," Ken said as he threw Mjolnir.
"Nooooo...." Avalo shouted as he actively tried to dodge, but Mjolnir course-corrected itself and struck Avalo, and just like Shiryu, he too died an untimely death in Impel Down. His last screams echoed in the huge place of Level 6, making everyone silent.
Ken wasn't done with Avalo. He went to another prison cell, the one that held Catarina Devon. She had an ugly face, and her smile was enough to make someone shudder in fear.
"Will you kill a harmless and innocent woman like me?" Devon said as Ken entered her prison cell. She had already seen what he had done to Avalo from another prison and was quite trembling at the moment.
"Madam, you are anything but harmless. You are wasting your life here anyways. Why not just liberate your soul, and also the Devil fruit will get eaten by a better person," Ken said while rotating his Mjolnir.
"I will do anything for you. You are a pirate, right? I can join your crew and be under you for the rest of my life," Devon pleaded.
"I don't need someone like you who doesn't have an inch of loyalty. It's better I send you to the afterlife," Ken said and threw Mjolnir. She screamed and furiously tried to dodge, but it was already too late. She died just like the others. This was horrifying, and never in the history of Level 6 of Impel Down did one see so many deaths in the same day.
They were the toughest guys in the world, and now they were dying like flies. Jinbe held a stoic face as he didn't feel anything for the people who had ties with the man that helped in capturing Ace. Ken wasn't done though, and he went on to kill Sanjuan Wolf and Vasco Shot.
They had huge bodies, and both of their cries echoed more loudly than the others. It was horrific. Both of them, with their funny faces, pleaded and asked to know why they were being killed, but Ken refused to answer and just sent them to their doom. The Level 6 was silent.
Even Crocodile, who was known for jumping around and throwing his weight, was silent and trembled a bit. After killing everyone who was supposed to join the Blackbeard Pirates, Ken stood in the middle of Level 6 and shouted.
"Listen up, you ugly and scummy bastards. Soon, someone called Blackbeard will come and say that he will free you if you join his crew. Well, you are welcome to join his group and do whatever you want, but remember, if you do join, I will hunt you down, I will find you, and I will kill you."
Those words were heard by everyone present.
"You are just a coward who kills people in their weakness."
"Do you think I am afraid of you?"
"You are just a weak bastard."
Shouts rang out from Level 6.
