微笑むSōsuke Aizen


In BLEACH, we see Sōsuke Aizen as a cruel character who used even his own superiors and subordinates as material for his experiments. His ostensibly gentle nature and warm embrace of his subordinates made him popular even outside the ranks, and he was adored by many who did not know his true identity. However, he had an ambition to reach the heavens, and he would go to any lengths to obtain it.

Shinji Hirako, who was then the captain of the 5th squadron, was the first to recognize him as a danger and went to the trouble of appointing him as the deputy captain of the 5th squadron to keep an eye on him. Although Shinji Hirako was a good judge of character, he was unaware of his ambitions, experiments, and activities behind the scenes. So, we will also introduce the curious end of Sōsuke Aizen, who was quite a schemer and the strongest of all, and his subsequent reappearance in The Thousand-Year Blood War, as well as Kurohitsugi’s strength.

Synopsis of BLEACH

BLEACH 7 (ジャンプコミックス) (日本語)


Ichigo Kurosaki, who is friendly with others, is sometimes treated as a delinquent by those around him, but he doesn’t care much because of his seemingly flashy natural hair. He lost his mother to the evil spirit Hollow and began training to become a Shinigami/Soul Reaper to become stronger. He has to work together with Kuchiki Rukia, who tends to take on everything on her own, to defeat a variety of enemies.

Profile of Sōsuke Aizen

Sōsuke Aizen’s calm and smiling personality in Bleach is actually his front face, and behind the scenes he has been doing all sorts of dark deeds to get himself into the heavens. He is currently the captain of the Fifth Squadron in Gotei 13, but 110 years ago he was the vice-captain of the Fifth Squadron. At that time, the captain of the 5th was Shinji Hirako, a blonde with long hair. He obtained the position of captain by making him a Hollow through his own Hollow experiment.

Ambitious and ruthless when it came to his own goals, he experimented with merging Shinigami/Soul Reaper with the vicious Hollow. The eight Hollows formed Visored to avenge him. The leader of the group was his boss, Shinji Hirako. He experimented on his fellow soldiers one after another, blaming others for his crimes and then banishing them.

Sōsuke Aizen Objectives

To be perfect?

In BLEACH, we see Sōsuke Aizen trying to become a perfect being in order to stand in heaven. For him, a perfect existence meant obtaining an immortal body. He believed that once he had an immortal body, it would only be a matter of time before he would stand in heaven. In order to obtain an immortal body, he needed “Hōgyoku,” a substance that could cross the border between Shinigami/Soul Reaper and Hollow.

にやりとするSōsuke Aizen


Hōgyoku, which allows one to obtain an immortal body, was developed 101 years ago by Kisuke Urahara, who was the owner of a candy shop (Urahara Shoten). Shortly after he completed Hōgyoku, he realized that he had created a rather dangerous substance. The spirit of Kuchiki Rukia, who was very serious and companionable, was chosen as the spirit in which to hide Hōgyoku.

However, Aizome, who is intelligent and ambitious, discovers the hiding place. This made Kuchiki Rukia, with her manly personality, a target more than necessary, and through his scheming, she was subsequently put to death. However, he is saved by his friends. Not one to give up, he succeeds in taking Hōgyoku in a different way and leaves Soul Society; with Hōgyoku in his possession, he succeeds in obtaining an immortal body and finally a perfect existence.

Reason for killing Soul King

Sōsuke Aizen, who has become a master calligrapher in BLEACH, has succeeded in acquiring Hōgyoku, which makes him completely invulnerable. Now that he was in a perfect state, he had a job to do. That was to kill the Soul King. However, the existence of the Soul King, who is the king of Soul Society, was known only to a few; he lives in the Soul King’s beautiful palace, which is guarded by the Zero-Guards.

凛々しいSōsuke Aizen


In order to defeat the Soul King, who was an eyesore in order to stand in heaven, he needed the royal key to get there. The key to the Soul King, who stands at the top of the Soul Society, required a heavy spiritual land with a radius of one spirit village and 100,000 souls. He was able to prepare all of these, and he was even going to create his own Zero Unit that would follow him.

He seemed to know the Soul King, whose existence was unknown even to the captain class. Therefore, he planned to kill the Soul King with great precision. With his ambition to stand in the heavens, he obtained Hōgyoku in order to kill the Soul King at the top of Soul Society.

Sōsuke Aizen was originally the main character of BLEACH?

Sōsuke Aizen has shown overwhelming strength, and some BLEACH readers have rumored that he was supposed to be the main character. Some BLEACH readers have rumored that he was supposed to be the main character. The main character in the story is Ichigo Kurosaki, who has orange hair, but he may have been whispered as such because of his overwhelming presence that surpasses his own. He had a strong impact on the audience, and his charisma was outstanding.

He was so highly acclaimed that some people said there was no one they liked more than him, despite the fact that he was a villain. However, it can also be said that it was because he was a villain that his charms were enhanced. If he had been the main character, he might have been too strong from the beginning and the story might not have been so exciting.

Sōsuke Aizen’s Personality



Sōsuke Aizen, the captain of Bleach’s Fifth Squadron, had a gentle personality and never stopped smiling, which made people around him trust him greatly. But this was only the front face of his personality. He was a very ambitious man who was ruthless and cruel, using his subordinates as pawns to achieve his own ends.

110 years ago, he was the deputy commander of the Fifth Squadron, and he used his superior Shinji Hirako and the captain and deputy captains of the time for his own experiments, turning eight of his best men into followers. However, he is ambitious to stand on his own in the heavens, and only recognizes Ichimaru Gin, an aloof and elusive character, as his only second-in-command.

Relationship between Sōsuke Aizen and Ichimaru Gin

Ichimaru Gin, once the captain of the Sambantai in Bleach, was looking for a chance to defeat him by approaching his nemesis Sōsuke Aizen and working as his subordinate so that he would not have to cry in order to protect the woman he had a single-minded love for. However, ostensibly, he had betrayed his former Sambantai and the other members of his unit to join the ruthless Aizen in rebellion. He had taken a shine to Ichimaru Gin, who had risen to the position of captain at a young age, and took Gin on as his second-in-command.

笑顔のSōsuke AizenとIchimaru Gin


Aizome, who could invoke Kurohitsugi, was the only one who recognized Ichimaru Gin, who sometimes did not know what he was thinking, as his second-in-command. However, he could treat his subordinates as pawns, and his true intentions were immeasurable, so when push came to shove, there was no telling how he would treat them. He seems to have trusted Ichimaru Gin, who betrayed his former comrades to come to him, more than his other subordinates, and went with him to the Hollow Sphere where the Hollows live when he achieved his goal at Soul Society.

Ichimaru Gin, who was the captain at that time, was a man of considerable ability. He was therefore regarded by Aizome, who was able to activate Kurohitsugi, and became a member of the group. However, he had planned to kill him for the sake of his childhood friend Rangiku, whom he loved with all his heart. He then gets the chance to do so, and performs a special move that he had hidden from him, but is unable to defeat the immortal he had become, and dies in the end.

Relationship between Sōsuke Aizen and Shinji Hirako

Sōsuke Aizen was able to activate Kurohitsugi in his final form in Bleach, but in the end he was defeated and sealed away by the inexperienced but righteous Ichigo Kurosaki and his friends who supported him. He then reappeared in the final battle of The Thousand-Year Blood War, helping his former enemies Shinigami/Soul Reaper to defeat their adversaries, the Yhwach.

勇ましいSōsuke AizenとShinji Hirako


Shinji Hirako has believed in the earnest Ichigo Kurosaki, who was able to defeat him, to the very end, and has guided him under his watchful eye since he was still in his infancy. He was a student who transferred to Ichigo Kurosaki’s school, where he was easily mistaken for a delinquent, and was the leader of Visored, but 110 years ago he was also Aizome’s superior who could activate Kurohitsugi. At that time, it was Shinji Hirako, who spoke in a Kansai dialect, who was the captain of the 5th squad.

Shinji Hirako, who had been suspicious of Aizome’s ostensibly calm demeanor since that time, had dared to put him under his supervision by making him his own subordinate, the deputy commander. However, he later used Aizome as material for his experiments and turned him into a Hollow, which led him to form Visored with other captains and others who were in the same situation and became its leaders. Therefore, the two had a history of a relationship that began 110 years ago.

|What happened to Sōsuke Aizen at the end? Will he reappear in The Thousand-Year Blood War?

Appears in Sōsuke Aizen’s last 1) The Thousand-Year Blood War

右眼を眼帯で覆うSōsuke Aizen


Kurohitsugi, a type of Kidō Corps in Bleach, had exceptional power among the Kidō Corps. In the final battle in the “Breach Arc,” Sōsuke Aizen succeeds in obtaining an immortal body by fusing with Hōgyoku, which he finally obtains, and assumes his final form. In doing so, he was able to activate the powerful Kurohitsugi, and when he activated the Kurohitsugi, he was in his final form, radiating a gravity so strong that it distorted space-time.

However, his Kurohitsugi was destroyed by Ichigo Kurosaki who, with the support of many of his friends, was able to unleash his power. He was defeated in the end, but he demonstrated a Kurohitsugi of tremendous power; he was defeated in the end despite activating the Kurohitsugi, and was then captured and sealed. However, he reappeared in The Thousand-Year Blood War, this time with his entire body in a state of bondage.



He was once on a rampage after activating Kurohitsugi and was considered a dangerous person even in his sealed state. He was therefore bound with strict restraints over his entire body. However, his power to activate Kurohitsugi was necessary for him to win the battle against Yhwach, the leader of the Quincy in The Thousand-Year Blood War.

Although his power was limited, he reappeared in The Thousand-Year Blood War to support the Shinigami/Soul Reapers of the Soul Society in their fight against Yhwach. He was able to use Kyōka Suigetsu, which has the power of “total hypnosis,” and he was able to hunt down his powerful foe Yhwach. In the end, however, he was defeated when his Kyōka Suigetsu was destroyed.

Appears in Sōsuke Aizen’s last 2) Activate Kurohitsugi

Sōsuke Aizen, who was able to obtain an immortal body, succeeded in activating Kurohitsugi in the Kamen Arc; he was also able to obtain the power of Kurohitsugi because he was able to obtain Hōgyoku and successfully fuse with it. The power of Kurohitsugi was one of the Kidō Corps, which combined exceptional power. Kurohitsugi, whose gravity was also destructive, had the power to distort space-time.



However, in a battle with Ichigo Kurosaki, a man with a strong sense of justice and a love for his friends, his strongest Kurohitsugi was destroyed, rendering it useless. He was defeated in the end, having lost his most powerful Kurohitsugi, and although he had demonstrated the power of his Kurohitsugi, he was finally sealed up and bound with restraints. However, he reappeared in The Thousand-Year Blood War when Yhwach became overwhelmingly powerful.

He was thought to be the breakthrough to defeat Yhwach in The Thousand-Year Blood War. Although he had been sealed off, he tried to use the power of Aizome, who had once activated Kurohitsugi, to defeat Yhwach, who had become the most powerful enemy in the Thousand-Year Blood War, and who was now trying to dominate everything. He thought he could defeat Yhwach by putting him into a state of complete hypnosis through his Kyōka Suigetsu. When the seal was broken, he tried to escape by activating Kurohitsugi, but failed.

|After Sōsuke Aizen

What happened to Sōsuke Aizen is revealed in the novel version?

BLEACH Can't Fear Your Own World I


Sōsuke Aizen reappeared in the final battle of Bleach, The Thousand-Year Blood War, and many people are wondering what happened to him after that. His subsequent condition was briefly described in the novel “Bleach Can’t Fear Your Own World.

Sōsuke Aizen was then imprisoned again?

微笑むSōsuke Aizen


Shinigami/Soul Reaper, who thought that the power of Yhwach, who appeared as the last boss in The Thousand-Year Blood War in Bleach, was too powerful to handle, released Sōsuke Aizen, who had been defeated and sealed up tightly as the final weapon, once and for all. Shinigami/Soul Reaper and others released Sōsuke Aizen, which they had once defeated and sealed tightly as their ultimate weapon. Thereby they succeeded in defeating Yhwach, who ultimately dreamed of Quincy’s resurrection. However, since Aizen, who had been the most powerful villain of all, had not died, many people wondered what happened to him afterwards.

A bit about what happened to him after that is discussed early in the novel “Bleach Can’t Fear Your Own World”. There, his business was done and he was once again imprisoned. Shunsui Kyōraku, the new captain general, is present at his sealing, along with several other captain-class colleagues. Just prior to his imprisonment, he uttered eerie and enigmatic words about Shinigami/Soul Reaper and Soul Society.

|Strength of Sōsuke Aizen

Strengths (1) Yhwach has a good eye for it.



In The Thousand-Year Blood War, which was the final battle in Bleach, the final boss was Yhwach, who commanded the “Invisible Empire” in order to revive Quincy. He was one of the most powerful of the villains. He seemed to recognize the power of Sōsuke Aizen, who took Hōgyoku and fused it with his own body and his original powers to become its final form. He was considered one of the “Five Special Forces.

He was a great help in The Thousand-Year Blood War, as he aimed at the revival of Quincy and others. Quincy and his friends’ resurrection, he did much to help them in The Thousand-Year Blood War. Even Yhwach, the most powerful of all the “rascals,” took a shine to Aizome.

Strengths (2) Final form in BLEACH Soul Ignition



In the game adaptation of Bleach, “Bleach Soul Ignition,” attention was focused on Sōsuke Aizen in his final form. Bleach Soul Ignition” is a game released in 2011, in which Aizen, who had ambitions to stand in the heavens, appears as a rusbosu.

As a result, his final form, in which he is active as a rusbosu, became a topic of discussion. In his final form at the end, he has evolved into a rather frightening figure. Later, in his final form, he became very powerful and strong, making it difficult for many players to conquer him. He was also active in the last The Thousand-Year Blood War, and his subsequent appearance as a villain in the game world will remain a focus of attention until the end of the game.

Strengths (3) Kyōka Suigetsu is a zanpakuto

微笑むSōsuke Aizen


The zanpakuto that Sōsuke Aizen, who showed his strongest power in Bleach, can handle is Kyōka Suigetsu. When he released his ability, there was no change in form. He had the power to put a person in a state of complete hypnosis once he saw the moment when he released his ability to use Kyōka Suigetsu. This was a terrifying power that allowed him to freely manipulate and dominate the other person’s psychic senses and the five senses.

It seems that he was able to perform his elaborate and elaborate deeds for 100 years largely because of the power of complete hypnosis in “Kyōka Suigetsu”. Kyōka Suigetsu” could control anyone, but it could not work at all with Ichigo Kurosaki, who was still carrying the burden of his mother’s death. He was defeated by Ichigo Kurosaki in the end and was sealed up tight until The Thousand-Year Blood War.

Strengths (4) Chairs and other restraints

剣を持つSōsuke Aizen


After being able to incorporate Hōgyoku, Aizome was able to evolve to its final form in the subsequent broken surface version. It was expected that Aizen would finally become a heavenly being. However, his ambition was crushed when he was defeated by Ichigo Kurosaki and others who did not tolerate his evil. He should have been executed, but he could not be killed because his body had become immortal after taking possession of the hōgyoku.

Therefore, he was sealed up tightly. During the sealing process, a variety of powerful restraints were used. These multiple layers of tight restraints would be used to seal him until The Thousand-Year Blood War. In the final battle of the Thousand-Year Blood War against Yhwach, the last boss of the tournament, he had to use his zanpakuto to fight while wearing the restraints (e.g., a white chair).

|Sōsuke Aizen does not use Bankai What is the reason?

凛々しいSōsuke Aizen


Aizome was the most powerful fighter in the final battle of The Thousand-Year Blood War, but he did not liberate Bankai. As he was a captain, one would expect him to be capable of releasing Bankai as well. However, the manga does not show him releasing his bankai power until the very end. Therefore, various rumors about his zanpakuto, Bankai, have been circulating.

Why Sōsuke Aizen does not use Bankai

Reason #1: Bankai is so strong that it is unnecessary.

にやりとするSōsuke Aizen


Aizen, who considers his subordinates only as pawns, does not release Bankai in his Zanpakuto, but the reason for this can be considered that he is strong enough to fight without releasing Bankai. He had shown his overwhelming strength and succeeded in acquiring an immortal body by taking Hōgyoku and fusing it with his own. In doing so, he was also able to acquire even more powerful powers.

Thus, in The Thousand-Year Blood War, even without the liberation of Bankai, he succeeded in hunting down the most powerful Yhwach, who appeared as the final boss. He may not have needed to perform Bankai’s liberation because his fighting ability was also enhanced by Hōgyoku, which allowed him to obtain an immortal body.

Reason #2: inexperienced in training

Sōsuke Aizenの横顔


Some people have speculated on the Internet that Aizome, who is not depicted fighting through the release of bankai, did not actually acquire bankai. He may have been so confident in his own strength that he did not feel the need to acquire bankai because he was able to do what he wanted to do with only the “Kyōka Suigetsu” from the release of the initial solution.

It is also rumored that he was unable to use it because he had no experience in training, since even the most talented fighter cannot release and use abilities that he has not acquired. It is unlikely that he did not acquire Bankai even though he is a captain class, but it is a possibility.

Reason #3: There is no Bankai itself.

凛々しいSōsuke Aizen


The reason why Aizome, who is an excellent trooper, did not release Bankai can be considered that his zanpakuto itself does not have Bankai’s ability. If he did not have the ability to use Bankai, it would be impossible for him to use it. There has never been a zanpakuto (a sword that is used by a samurai) that does not have the ability of bankai, but it is not surprising that there is such a zanpakuto.

If Kyōka Suigetsu itself, in its initial state, has already reached the level of Bankai, then it is fully equipped with this power and does not need Bankai. It is not surprising that he has an irregular zanpakuto, so his zanpakuto may have had a special element that made it different from those around him with the most powerful abilities.

Reason #4: People around me have no memory of Bankai.

怪我を負うSōsuke Aizen


The zanpakuto released by Aizome, whose true feelings are difficult to grasp, is also equipped with the ability to release Bankai, but it can also be considered to have an element of being able to attack without giving the people around it the memory of Bankai or the memory of Bankai because it is an even greater ability than “Kyōka Suigetsu”. The moment he unleashes the technique, he sees it.

If the moment he releases the technique, the memories of all those who saw it are completely lost, then it is not surprising that the attack of the release of Bankai’s solution by his zanpakuto is not remembered at all. It would not be surprising if Bankai, which should be more powerful than Kyōka Suigetsu, which has the power of complete hypnosis, has the power to leave no memory.

|Summary of Sōsuke Aizen

凛々しいSōsuke Aizen


Sōsuke Aizen, who had the ambition to stand in the heavens, used eight of his colleagues in the captain and vice-captain classes to conduct his experiments. Many other Shinigami/Soul Reapers and humans were also victims of his experiments. Therefore, there were numerous people who held grudges against him.

He was a ruthless character who was selfish and would use his subordinates and all others as pawns for his own ends, even though he appeared to be a gentle and kind-hearted person. He was ultimately defeated and imprisoned by Ichigo Kurosaki and others who tried to bring him to justice, but he became very popular because he was a fascinating character as a villain.
