So the story starts from the introduction this is the main character Whose name is Mr. Satan and his family consists of 6 members
He, his younger brother Yami, his parents Asahi Yamazaki and Mito Yamazaki
Grandparents Rin Yamazaki and Grandma Akihiko
They live on a small island
And to travel they have to take the help of hot air balloon
And a new hot air balloon agency just opened
But that agency isn't normal
The owner of that agency is a mastermind killer
He made the hot air balloon larger so that one of his employees can hide in the balloon
As soon as they are 700m high the worker of that agency comes out and loots their client then murders him if he were to be rich
And when the client doesn't return and their family member asks about them they tell them that he got lost in the town
They did this business for a long time
Then one day , one of the main characters cousins goes to that agency
While roaming around he finds one of the dead spots in the wall
From there he listens
The employees and owner speaking about him
He heard that
They were saying he won't have that much of a money or something cause he ain't an adult so killing him would be a waste so let's let him live
After a week or something he joined that agency because his parents forced him to because their financial conditions weren't that good
So he joined it
Then one day the main characters father who is a business man and his younger brother went to fly on it
So the main character came to drop them
After the main character drops his father and younger brother at the agency he roams around that agency
His cousin was just waiting for a chance and as soon as he got the chance he told the main character everything about the company
The main character didn't believe him at first but then the cousin showed a voice recording of what they said to him
He could've done a case but because he doesn't have that much money his words won't reach people easily.
After knowing everything the cousin told the main character that other than him there are 2 guards and both of them carry a gun and the owner carries one as well
So to get rid of that gun the main character while roaming pressed the fire alert button.
So that everyone got wet the cousin took out the ammo from the guns
After pushing the fire alert, Charles, main characters cousins empties the guard and owners guns.
After doing that Main Character Satan goes up 5 mins before the balloon in which his father was about to fly, then finds the employee of the company, hearing all this recket the owner comes up, The main character said that he knows about their secret, and the owner said that he knows it, his men were observing Charles because he was acting all fishy when you came, and he knew what Satan has done, that's why he brought another gun which had ammo and both of his guards brought one as well, seeing that the main character still didn't panick cause he had a solution for this as well, his younger brother who is 14 years old is a Karate black belt and the top 2 in top 3 islands karate championship, he told his younger brother to deal with the guards, and the main character himself went head on to take down the Owner all by himself, Younger brother Yami was 2nd in the in the top 3 islands karate championship because the first place was Satan himself.
Now that the fights have begun, Charles and Kratos versus the other 2 guards and Satan Versus The owner whose name is Yamamoto. While fighting the 2v2 was going good but, the 1v1 was different, While fighting Yamamoto Satan noticed something.
So...
While fighting the owner of the company Satan notices that his hits aren't affecting him, he understood at that very moment that this guy's body is as tough as an iron wall, fighting it won't be easy, so he gets serious, Satan is a
master of dodging and has insane speed, he used his insane speed and dodging abilities to hold him until his younger brother finishes the guard, while fighting the owner he noticed something, he noticed that the owner is always try to protect that one spot on the left side of his neck, from that thing he knew that the weak spot of the owner is that part, so he started fighting while aiming there and dodging the attacks at the same time
Till then the younger brother's fight is over, Satan calls his younger brother saying. 'Yami!'
Yami rushed to help his elder brother, they both had a sign language between them that they used to talk with, talking in that way Satan told Yami that he ( Satan ) will try to create an opening and as soon as I create one you'll strike at the left side of the neck
Satan was flashing from left to right punching and punching, the owner slowly understood what they were up to so he started fighting with the younger brother as well
While fighting him he understood one thing, that the younger brother has just a little less durability than him, knowing that he knew it would be difficult for him to fight both of them at once
And Satan also understood what The owner was up to
He Used his karate techniques to deflect the strikes the owner did while saving his brother and distracting the owner all at the same time
The owner had the explanation in front of his eyes that why Satan was the one who won against Yami
Yami who was fully focused on the neck as soon as he saw an opening he striked
The strike that made him drain all his energy, but it was worth it cause the owner slowed down a little and that was the time when the main character shined
He started flashing left-right again and again and striking both sides of the neck
Soon the owner fell unconscious
As soon as he fell both brothers stood still
Both brothers fell unconscious after this overwhelming fight
Till that time the owner of the company had called 8 men of his
The guards also reached before the owner woke up again
The Main Characters father Asahi Yamazaki
Cased a fir against the owner of that company
Whereas Satan and Yami were in the hospital for 2 weeks
They were discharged just 2 days after Asahi won the case
During the evening Yami his father and Satan all three of them were watching television in their living room
They saw in the news which said that this agency consisted of murders and have more businesses which do different work like this
Hearing that Satan's blood started Boiling
The younger brother knew what it was that Satan wanted to do the most
After fighting the first agency both brothers knew they are no match for any other agency right now
Knowing that they went to an old monk who tells you the martial arts that is well suited to you
Both brothers physique was checked and both of them lived with that monk for a week
After one whole week the monk told Kratos that Martial Arts style that is most suited to him is Muai Thai
Whereas for Satan, he said that he is the 2nd one he has ever seen who is capable of learning every arts of fighting..
