Don Krieg is an idiot and a jerk
Mihawk spent several minutes trying to convince Luffy to change his mind to no avail. When Luffy decides something there is nothing in the world that makes him change his mind.
It is a losing battle.
Natsu was enjoying the show until Don Krieg thought it would be a good idea try to provoke Mihawk after fleeing in terror back to East Blue after the last encounter.
What an idiot.
-Hawk Eyes!- Don Krieg called out Mihawk's nickname with a big smile.- Did you come all the way out here for my head? The head of the infamous ruler of East Blue, "Don Krieg"!?-
Mihawk looked at him seriously for a few seconds before turning his attention back to convincing Luffy to call him dad. He thought that if Luffy started calling him dad then Crocodile would agree to marry him when he proposed to him.
Seeing that Mihawk is not going to deal with this cocky idiot, Natsu decided to deal with him.
-Oi. If you want to pick a fight then fight me.-
Don Krieg scowled at him, but still decided to attack him. He must have smoked something strange during this period of time because he almost fainted from fright when he saw Natsu.
-Fire Dragon's Roar.- Natsu quickly gathers and releases a large quantity of flames from his mouth at his target.
Natsu sent him flying and sat on the boat. Meanwhile, Luffy jumped up to Zeff, leaving Mihawk with a dejected frown, indicating his defeat by Luffy.
(Not even the strongest swordsman in the world can make Luffy change his mind!!!)
-Hey uncle Zeff! If I chase them away for you, will you let me of Sanji?- Luffy asked pointing to Don Krieg's men with a huge grin.
-Fine, do as you wish.-
-Hah!? Wait a fucking minute!!! Are you selling me for a pirate cleanup, old man!? - Sanji asked from Going Merry, stopping arguing with Zoro.
-I can't?-
-Obviously not!!!- Sanji yelled angry.
-Pff. What a crybaby, Ero-cook.- Zoro crossed her arms and scoffed at the blond man.
-What did you say, Marimo!?-
For some strange reason Sanji can't control his anger against Zoro. He tried to reassure himself by reminding himself that she was a lady and he should be respectful of her, but every damn cell in his body was screaming at him that he wanted to fight her.
Before he knew it he was already in another ridiculous argument with her.
(Author: By the power granted to me by the canon, you two will argue a lot, but you will love each other very much at the same time. Gahahahaha!!! Praise my greatness!!!
Zoro: *pulls out her swords*
Sanji: *prepares to send the author flying with a kick*)
(↑↑↑ Ignore this. She is crazy.)
-They look like a newlywed couple.- Nami commented with a snort.
-Definitely.- Usopp nodded with his hands behind his neck.
Time flies and Mihawk had already left the place a long time ago because if he takes any longer, he'll be late for the Shichibukai meeting.
(Honestly, he doesn't care about those boring meetings. He's just there for Crocodile. Accepting the Shichibukai title was the best decision he ever made. Thanks to this decision he was able to meet the love of his life.
With the mere presence of the taller man he is able to put up with extremely boring hours listening/ignoring what Sengoku had to say during every meeting.)
Natsu watched Luffy fought without intervening at any time.
The fight was a disaster. It is not known exactly how it happened, but at some point Luffy's fight against the Krieg Pirates turned into a fight between Luffy and Don Krieg.
-Let's go Zeref. Luffy will take care of the rest. Right, Luffy?- Natsu asked.
-Yes!! I'll take care of everything! - Luffy answered with a grin.-
-Are you sure?- asked Zeref preparing the boat.
-Yeah. Luffy is strong and he need to accumulate experience through these battles. Who am I to take away Luffy's chance to have an adventure on his own? After all I only planned to come say hello and eat.- Natsu said shrugging his shoulders with a toothy smile.
-As you wish.-
-Goodbye, Natsu-nii, Zeref-nii!! I'll see you at the Grand Line!!!-
-Bye Luffy!!! Take care and make sure you don't die!!!-
-I will!! I still haven't achieved my dream of being a Pirate King so I don't plan on dying!!!-
With that Natsu and Zeref left. Don Krieg took the opportunity to play dirty and drop a poison gas bomb.
They all jumped into the sea, but Luffy couldn't as he possessed an Akuma no Mi while Zoro was too injured to jump into the sea.
There were only two gas masks and Gin sacrificed himself to cover Zoro's face with the mask Luffy threw at him, poisoning himself in the process.
This completely pissed off Luffy and his expression turned very serious.
-Hahahaha! What a fool! That's what he gets for thinking he's eternally indebted just for receiving some crub.- Don Krieg said with cruelty.- Well... Idiots will never understand until they die... Ahahaha!-
-D... On...?- Gin was crying with a bloody nose.
-Gin... It seems you've chosen the wrong man to follow!- Sanji said helping Gin sit up after getting out of the sea.
-KRIIIIEG!!!-
Yep. Luffy is pissed. REALLY pissed.
Nothing in the fucking world could save Don Krieg from an extremely pissed off Luffy. Everyone could only watch as Luffy was beating the man to death with his Armament Haki covered fist.
We can only pray that the medical level of this world is high enough to fix that man's disfigured face because not even he himself would be able to recognize his own face in the mirror after this.
Amen.
