After Aizen walked out of the blood-soaked and chaotic gold exchange, he opened the information he was holding about Mano Seiichiro, a Jonin from Kumogakure.
The intelligence photo shows a dark-skinned, rugged-looking man: Mano Seiichiro, male, 27 years old, a veteran Jonin Kumogakure, specializing in Kumogakure-Style Kenjutsu, and also possessing considerable skill in Lightning Release Technique, making him a standard Kumogakure ninja.
This kind of ninja skilled in Taijutsu was exactly what Aizen was good at countering. With a smile on his masked face, he thought this mission would be very easy.
Before long, he arrived at the outskirts of Kumogakure. After observing his surroundings, he used his Makeup Jutsu to infiltrate Kumogakure as a merchant who wanted to issue a mission.
Upon entering Kumogakure, he found the Kumogakure to be quite bustling with a diverse array of people. After inquiring, he learned that due to the war between Konoha and Sunagakure, those who needed to issue missions had come to the relatively peaceful Kumogakure.
However, this situation also provided favorable conditions for his infiltration. Without wasting too much time, Aizen followed a Kumogakure into a secluded alley and controlled the Kumogakure with Genjutsu before being discovered.
"I'm asking you, where is Mano Seiichiro?"
Controlled by the Genjutsu, his eyes glazed over as he stared at Aizen, uttering the information Aizen wanted. " Mano is in Valley of Clouds and Lightning."
Aizen was surprised that the Kumogakure he controlled with Genjutsu actually knew where Mano Seiichiro was. He had been prepared to take his time to search, but he found him by simply controlling one of the Kumogakure.
"Oh, good luck. But Valley of Clouds and Lightning, that name sounds familiar."
Aizen the name Valley of Clouds and Lightning somewhat familiar. After recalling it carefully, he realized that this was the place where Eight-Tails Jinchuriki, Killer B. In the original story, Sasuke was brutally beaten by Killer B here.
"Isn't Valley of Clouds and Lightning Killer B the place where Eight-Tails Jinchuriki of your Kumogakure, lives? Can ordinary ninjas really enter there?"
"No, although Lord Killer B trains there, the vast terrain and frequent flashes of lightning make it ideal for training as Kumogakure. Most Jonin also prefer to train there."
Having understood the reason, Aizen turned and walked towards the direction of the Valley of Clouds and Lightning. As for the Kumogakure that was controlled by Genjutsu, Aizen had already given him Genjutsu hint that he would find a mission to leave the village in two days and then die on the mission.
Although the ant that provided him with value has the right to survive, he cannot reveal himself at this stage, so he can only ask him to die.
Gradually, the area where Aizen walked became less and less populated, and the terrain became higher and higher. Before long, Aizen arrived at a man-made platform, where he saw his target Mano Seiichiro.
At this moment, Mano Seiichiro had his eyes closed, seemingly lost in thought.
However, upon hearing footsteps, he immediately opened his eyes and, looking at the merchant-looking figure before him, said with a hint of authority in his voice, "This is not a place for you. If you wish to issue a mission, please go to the mission department."
Mano Seiichiro mistook Aizen for someone who had come to issue a mission, and because he was unfamiliar with the terrain of Kumogakure, he stumbled upon the place by mistake.
After he finished speaking, he closed his eyes again. He had just encountered a problem related to his cultivation and was now deep in thought.
"I am indeed here for a mission, but not to issue one; I'm here to complete one."
Aizen spoke in a gentle tone, showing no anger at Mano Seiichiro. In Aizen's view, there was no need to bother with the dead.
Upon hearing Aizen's words, Mano Seiichiro immediately realized something was wrong. He opened his eyes, jumped and rolled several times, and quickly leaped backward, increasing the distance between himself and Aizen.
"Who are you? What is your purpose in infiltrating Kumogakure?" Mano Seiichiro realized from Aizen's words that the person in front of him was probably an enemy who had secretly infiltrated Kumogakure.
However, he looked relaxed, and he even felt a little amused. How foolish would someone be to think of causing trouble inside the Kumogakure, and then expose themselves in front of Jonin like him?
"Boy, which village are you from? How dare you be so ignorant as to sneak into Kumogakure and even show your face in front of me." Mano Seiichiro looked relaxed, as if the enemy in front of him was just a piece of cake.
However, seeing Aizen remain unmoved and silent, still maintaining his indifferent demeanor, Mano Seiichiro felt a surge of anger rising within him, a sense of being slighted. "You won't talk? No problem. Once I capture you and throw you in the Konoha Torture and Interrogation Force, you'll tell me everything."
He reached behind his back to draw the Ninja Blade he carried on his back and subdue the enemy, but before he could draw the Ninja Blade, he heard Aizen's voice in his ear.
"A monkey that only knows how to squawk and squeak cannot fight against a god; there is a difference between being famous and being human."
Mano Seiichiro looked in Aizen's direction and saw Aizen walking towards him leisurely, looking as if he were not fighting, but sightseeing and enjoying flowers.
This nonchalant attitude initially made Mano Seiichiro sneer, but it also fueled his anger.
He wanted to draw his Ninja Blade to show this arrogant brat the strength of Kumogakure, but a strange thing happened. He tried desperately to draw his Ninja Blade, but found that he couldn't do it no matter what he did. It was as if his Ninja Blade and scabbard were stuck together, and no matter how much force he used, he couldn't pull it out.
He broke out in a cold sweat, and suddenly realized that the enemy on the other side must have done something to him.
Seeing Aizen getting closer and closer, and realizing he couldn't draw his Ninja Blade, Mano Seiichiro had no choice but to abandon his idea of using the Kumogakure-Style Kenjutsu and prepare to create distance to fight with Lightning Release.
Just as he was about to lightly step back, he discovered that he couldn't even control his body. No matter how he tried to move his body, it wouldn't react at all. He remained standing in the position of drawing his sword, watching Aizen slowly approach.
Only then did he realize how terrifying the enemy was, managing to Jonin like him without warning. He also deeply regretted his underestimation of them.
However, Mano Seiichiro did not give up. His mind raced as he considered strategies to counter the enemy. Suddenly, he wondered if the Genjutsu had disrupted his senses, causing him to be unable to move.
The more he thought about it, the more sense it made, so he immediately unleashed his Chakra in an attempt to disrupt the flow of Chakra within his body.
But something even more despairing happened: no matter what he did, he couldn't disrupt his Chakra, as if the Chakra within him wasn't his own and was completely beyond his control.
"How is this possible?" Mano Seiichiro was filled with despair.
In his despair, he also heard the enemy's voices.
"Although you were just an ant, Jonin a Jonin, you are the first Jonin to die by my hand. As a reward, I will remember it."
Aizen's tone was tinged with gratitude, but the content filled Mano Seiichiro with terror. However, he was helpless; he knew he was doomed. In this remote training ground, no one could save him. He could only stand still and wait to die.
Aizen walked up to Mano Seiichiro and saw surprise, fear, anger, and despair in Mano Seiichiro's eyes.
However, he didn't care at all. He raised his hand and easily drew the Ninja Blade that Mano Seiichiro thought was impossible to draw.
Then, with a light flick of his wrist, the sharp Ninja Blade easily sliced across Mano Seiichiro's neck without pausing. A large amount of blood gushed from his neck.
Mano Seiichiro's consciousness gradually faded into eternal silence, and the only question that remained in his mind before his death was this one.
"How exactly was all this accomplished?"
