Even an elite Jonin could hardly resist against Yama, and the young Sasuke, who has yet to even start his training as a Shinobi was really frightened.
Yama didn't care about Uchiha Sasuke's panic and walked towards him step-by-step.
Sasuke could hardly retreat backward and spoke with a trembling voice, "Y-you… w-what are you g-going to d-do?"
Yama clutched Sasuke's head with his right hand and lifted him in the air, staring at the kid's black eyes, Yama spoke with a cold tone, "You know kid, coming here headfirst was the wrong decision, but it appears you are lucky, you know why? Because you are a pathetic kid, didn't even awaken the Sharingan yet? Seems to be useless to me."
Sasuke's face was red in nervousness, he clutched Yama's hand with both his hands and tried breaking free, but his struggle was not even worth any attention for Yama.
Homusubi was also looking at Sasuke with his face full of worries.
Although he knew that Yama is just putting an act and wouldn't actually hurt the kid, he was nonetheless worried that this experience may leave a trauma on the kid's immature mind, after all, Sasuke is still too young, and hasn't yet experienced the cruelty of a battlefield.
At this time, Yama held Sasuke by the neck, and lightly whispered in his ear, "You appear to be so pathetic that you aren't even worth killing, maybe you should be glad and be happy of your incompetence!"
Sasuke who was struggling and flailing his legs in panic tried to punch Yama with whatever strength he could muster but all that felt was a tickle.
"Heh, I guess you don't even know how to punch someone, right? Don't worry I am going to show you, once you experience the pain, I think you will never forget how to land a heavy hit!" – saying that sentence he closed his right hand and hit a punch on the kid's face, the strength used was just right so that the kid would feel pain but Yama also made sure that it doesn't leave any permanent damage.
"Aaahhh…!"
However, even this punch was too heavy for Sasuke, and his consciousness started to get blurry.
Yama ignored this and hit another punch in the kid's gut, causing him to choke out saliva mixed with blood.
Sasuke was now almost unconscious and thrown at the side like trash.
The strength again was just enough to not hurt too him badly but just enough to hurt the young Sasuke.
The main reason Yama did such a thing was to create an outline for people to understand that Amatsukami is a really cruel and dangerous organization such that they remain on edge and be vary of its members, sort of like a deterrent effect.
If someone can be cruel to such a young child, then it is unknown where their limits lie.
Otherwise, if he had just ignored Uchiha Sasuke and left the kid to his devices then not only the village but even the Uchiha Clan might feel suspicious about this whole kidnapping, after all, the obvious response would be to immediately kill the kid to not leave any witnesses.
As for the other reason, Yama decided to put some early pressure on the Uchiha Sasuke to stimulate his growth, Yama is obviously going to make sure that the Uchiha Clan is not annihilated, which means, Itachi wouldn't become a criminal, therefore there has to be someone else, someone towards whom Uchiha Sasuke's hatred would be directed.
As for why he is doing so?
Isn't it obvious?
Similar to Uzumaki Naruto, Uchiha Sasuke is also the Child of Prophecy!
Hyuga Kuroto is confident in himself, but this doesn't stop him to ensure more options in the case things changes and takes a turn for the worst-case scenario.
The plot has long since deviated from the original story, and there is no telling what the future look might like, therefore, the more options you have in your hand, the better.
If the situation gets too critical then Uzumaki Naruto and Uchiha Sasuke will come in handy as the trump card, to save the day.
Besides, the enemies aren't limited to just the other shinobi villages and Akatsuki, there are unknown numbers of Otsutsuki clan members spread out throughout the stars and it is unknown when they might come and attack Earth to plunder the Chakra.
As for the question that this might leave a shadow in Sasuke's heart?
He isn't worried, the term 'Child of Prophecy' explains it all, the halo of the protagonist will help Sasuke overcome all the challenges.
Suddenly, Yama noticed that a lot of Chakra signs were appearing in the vision of his Tenseigan.
Understanding that a large number of shinobi were coming here because of the emergency signal flare, Yama didn't waste any more time and used the Gravitational Traction of Rein Wheel Pull to lift unconscious Uchiha Hideki in the air and nodded towards Homusubi, "Let's go, we will follow the plan!"
Homusubi glanced at Sasuke's painful appearance, nodded with a hesitant look, and disappeared from his spot.
…
Uchiha Clan Grounds.
Uchiha Itachi, who just came back after completing the mission was walking towards the direction of the shuriken training field when he found out that Sasuke has yet to return home.
Itachi couldn't help but smile slightly at the thought of making his brother wait for too long.
The fact that Sasuke loves him so much really warms Itachi's heart.
Spark…. Whistleeeeeee… boom…
While still on the way to the training field, Itachi noticed the signal flare in the sky.
Looking up at the flare, Itachi's onyx eyes shrank, because he realized that the flare is an emergency signal of an enemy attack, moreover, the direction the flare was fired from seems to be very close to the agreed spot.
"Sasuke!" – The first thought that came to Itachi's mind, was that Sasuke is in danger.
Without wasting even a second, Itachi's figure disappeared from his spot and rushed towards the direction of the emergency flare using the body flicker technique.
Similar to Itachi, many Uchiha Shinobi discovered the emergency flare and immediately rushed in that direction, so the number of people rushing towards that direction became a large number.
Not only the members of the Konoha Military Police Force, but even many of the other Konoha Shinobi also rushed in that direction, upon noticing the emergency flare.
In everyone's understanding, the red flare is only used in the case of an enemy attack, the last time it was used within Konoha was during the Kyuubi's attack, and the mere thought of something like that happening again frightened everyone.
It wasn't long after Homusubi and Yama disappeared, and a large number of ninjas arrived at the place where Uchiha Hideki was ambushed.
The sight that greeted them wasn't that of an enemy attack, nor was there signs of the presence of any enemy, just a young child who knelt on the ground and choked out blood.
A non-Uchiha shinobi stepped forward and questioned the child while using Iryo Ninjutsu on the kid, "Hey kid, was it you who used the emergency flare?"
Because there were no signs of any fighting, so all he could think of was that the child might have accidentally fired the emergency flare.
It was at this moment that Uchiha Itachi arrived, seeing Sasuke kneeling on the ground and trying to get up but failing, he hurriedly went towards his brother, and checked his condition, Itachi noticed that Sasuke was not severely injured, and some of his injuries were already treated and sighed in relieve, but he didn't drop his guard and watched the surroundings carefully.
Whooosh… Whooosh… Whooosh…
The ninjas continued to rush here, and everyone surrounded Uchiha Sasuke, their eyes focused on him, seemingly waiting for the answer.
Itachi squatted down beside Sasuke and asked gently while helping his brother stand up, "Sasuke, what happened just now?"
"Nii… Nii-San… Uwahhhh…!" – Seeing Itachi, Sasuke rushed forward and buried his head in Itachi's chest, the tears he has been suppressing couldn't be held back anymore, and flowed out.
Itachi was obviously a little taken aback, but he calmed down and gently rubbed his brother's back to soothe him, "Alright, don't cry Sasuke, I am here, aren't I? And aren't you a strong boy? Can you tell me what happened? Who fired the emergency flare?"
For a while, Sasuke continued crying and he could hardly speak anything understandable.
Itachi didn't put pressure on Sasuke and helped him calm down. Itachi could see that his brother has experienced something terrible based on trembling and the painful look he has.
So, he didn't want to pressure his brother.
After he calmed down a little, Sasuke who still had the snot and tears on his face, spoke. "T-thele wele t-two stlange people cough-cough… with… with s-scaly mask… a-and they attacked... unkle Hideki… they… they were very powerful and defeated Unkle Hideki easily…and… cough… a-a-and they… they alsho p-punchd me hard in the face and tummy…uwwwaaahhhhh… it was scary… uwwaaahhhh….."
(Translator's note: Okay that was a bit too much, I don't think Sasuke would cry such pitifully… but anyway, let's just assume he did.)
"What!?" – The Uchiha shinobi were all taken aback.
Initially, they all thought that it was probably the young Sasuke who fired the signal flare because he encountered some dangerous creature in the forest.
But now that they heard that Uchiha Hideki was attacked, they all realized the seriousness of the matter.
Even Itachi was taken aback, but he concealed his surprise very well and calmly listened to Sasuke, when Sasuke was finished, Itachi spoke, "It's alright Sasuke, I am here now, nothing will happen, can you tell me what kind of appearance did the attackers have? Did you see them?"
How can Sasuke forget the appearance of someone who might have inflicted some nightmares in the kid's subconscious? So he spoke and described the outfit that the two of them were wearing, "B-both of them were wearing black cloaks with strange golden patterns on them and a strange mask to cover their faces!"
"Black Cloak with strange golden patterns, and a strange Mask?" – Itachi's face sank, it wouldn't take a genius to guess the identity of the attackers.
To confirm his guess, Itachi asked, "Can you remember what type of masks they were wearing?"
Sasuke nodded while wiping away the snot with his sleeve spoke, "One wore a scary black and white color evil mask, and the other one who defeated Uncle Hideki wore a fire patterned mask!"
"Sure enough, it's Amatsukami!" – came out the voice from the canopy of a nearby tree.
Attracted by the voice, everyone turned their heads and found the figure of Uchiha Fugaku standing there with a gloomy look.
