Squid Squid no Mi (BlackSquid Model) is a Zoan type Akuma no Mi that transforms those who eat it in a Black Squid. But, what is a Black Squid? A Black Squid is a derivative type of a normal squid, but extremely poisonous. Its poison can paralyze an elephant in one go instantly. It's an Uncommon Zoan. Haruno knows it because he himself was paralyzed by the poison of this squid. He was learning to fish with Luffy and Ace and he got that squid, who flew in his face and... Well, you know what happened next. Haruno knows that one sting is in one of the tentacles...
But he doesn't know what tentacle! After Joly transformed himself, Haruno saw a big black-skinned squid with six tentacles attacking him at the same time, he could win with one attack, but no. He wants to try his abilities. Then he opened a portal in his feet, teleporting himself on top of the squid head. He used his fist and punched the squid face, making a burn mark! Haruno smiled and jumped backward to avoid two tentacles that were going to hit him and landed slowly. Now it is time to play! He opened two portals in front of himself, then punched the right one.
When his fist touched the portal, another portal appeared in the squid face and Haruno's first hit it. Then he said: "Attack Portal: Portal Fist." With a smile, he punched the portals several times it was so quick that you could see just the after image! Haruno said slowly: "Attack Portal: Gatling Fist Gun." The squid's face was completely destroyed by Haruno's punches but wasn't dead yet. Haruno had a good idea. He removed from his storeroom a bag, what is inside? You will know later. Then he looked at the squid and said: "You are very weak. But, let me try more moves on you so i can see if it works!"
Haruno then used his skill [Telekinesis] and aimed towards the squid. Then bang! A tiny hair flew toward the squid and penetrated its body, making blood flow over it. Haruno then decided to end his life with a beautiful move! He clapped his hands and two fireballs appeared on it, using his [Soul Fire] skill and [Fire Control] skill, he manipulated the fire to form claws in his hands, then he jumped and teleported himself toward the squid. When his claws touched the squid, the squid screamed and black blood flew out Haruno said slowly: "Fire Control: Fire Claws." Then its body began to turn into a human again.
Haruno smiled and waited to the squid transform into a human to remove its head. After transforming, the pirate captain looked at Haruno like he was looking at a monster, Haruno smiled and asked: "Who in your crew has rewards?" The captain couldn't speak so Haruno touched his forehead and used one of the skills that he trained! "Memory Read." He could do this to animals easily, but to humans, he needs to break their mind or body to read their memory. After reading his memory Haruno cut off his head and the head of two other guys. He called Gaharudo again and when he was flying in his backs, he used his skill [Soul Fire] and concentrated a good amount of SE making a fireball and shot it toward the ship, making an explosion.
Then he returned to the merchant ship. He landed slowly and stored the head of the three that he cut off in his Akuma no Mi and floated toward the bird's nest in the ship again to sleep. But his Kenboshoku no Haki could catch some speeches of the crew down on the ship: "Did you saw that explosion?" "What kind of Akuma no Mi he uses?" "So strong!" And etcetera. After sleeping for three or two hours, he woke up with one guy of the crew shouting: "Pirate Hunter-san! We need your help here!" Haruno looked down and saw another ship with a black flag. He sighed and jumped off the bids nest to the pirate ship and float with [Telekinesis] and landed slowly on it.
He looked around at the stunned and surprised pirate crew and said just one word, asking: "Bounty?" The others looked at him with a confused expression and the one that seemed like the vice-captain or something like that said: "The captain has a bounty of thirteen million! And i have a bounty of two million! ... Wait... Who are you bastard to invade our ship!?" Haruno snored lightly and suddenly his body disappeared and appeared near the big guy and touched his forehead. Then he screamed with pain because seconds after his head was burning with red flames! Haruno smiled and said: "Fire Control: Fire Touch." Then he snapped his fingers, the fire stopped but the head of the guy fell off instantly! Haruno said to himself again: "Attack Portal: Portal Cut." He used his portals to cut off the head, like when he was in the ship of the Black Squid Pirates. The crew was completely stunned! Their vice-captain was killed so easily! This guy is a monster!!
Then the captain appeared and shouted: "What the hell is happening here!?" He looked around and saw Haruno collecting his vice-captain head with a serene and happy expression, this made him stunned and he couldn't react because of his head that fell in the ground. Then Haruno remembered about the bag that he warped around his wrist, he decided to open it in the merchant ship. He collected the other head and simply left the pirate ship, but he didn't forget about burning it down. He landed in the merchant ship and flew toward the bird's nest one more time and with a happy expression, he opened the bag that was around his wrist! Inside it was fruits. Yeah, fruits! And you what!? Yeah, when you kill an Akuma no Mi user, its Akuma no Mi returns to a fruit!
So when Haruno saw the two fruits that changed color he smiled.
