Akaza is the upper rank 3 Demon of Muzan Kibutsuji‘s 12 moon demon army.

Expert in martial artist Akaza, too like the other demons in the upper moon 12 ranks, had heart-wrenching backstories.

He was previously known as Hakuji before transforming into a demon. In this article, we will discuss all the details related to the backstory of Akaza, how his early life was, how he was transformed into a Demon and his love story with Koyuki.

Every detail related to Akaza will be discussed in this article. So without further ado, let’s discuss the details.

Akaza’s Backstory

Akaza’s early name was Hakuji Soyama; born and raised in slums from his early childhood, he had difficulties managing his family.

Hakuji’s father had a serious ailment. To provide for his father’s medicine, Hakuji used to do unethical works such as pickpocketing from the town’s people, stealing, etc.

For this, even he was caught could of times, and the magistrate beat him up and marked his head with tattoos and called him names such as Demon Child.

One day Hakuji’s father hanged himself because some villagers told him that his son got arrested again for stealing and pickpocketing. Hakuji’s father wanted his son to live a straight life, but the circumstances for Hakuji were such that in order to provide for his father’s medicine, he had to steal.

Hakuji’s father left the last letter to Hakuji; there, he told his son that he wants him to live a straight life and wanted him to earn by honest means and not by pickpocketing or stealing.

After his father was gone, Hakuji now had no one and no place to live, and devasted by his father’s loss, he became very angry with the people of the village.

He started beating people and even killed several men in the village; then, he was approached by Keizo, who used to run a loco dojo center in the village.

Keizo saw something in Hakuji, but Hakuji, on the other hand, was annoyed with Keizo and challenged him into a fight.

Keizo defeated Hakuji with ease and then told him he would give him shelter to live and food every day, but he will have to take care of his daughter, who is currently sick.

Hakuji previously took care of his father, so he knew how to take care of Keizo’s daughter as well.

Although Hakuji was an expert in taking care of the ill so this wasn’t a problem because, in the past, he had taken care of his father, but here Koyuki wasn’t like most other girls. She used to burst into tears for tiny things.

But Hakuji knew how to motivate her; he once promised her that he would take her to a local firework once she has recovered from her ill health.

One day Hakuji discovered that Koyuki was forced outside and was left by the nearby Dojo owner. The nearby dojo owner had always been eyeing Soryuu dojo and was always jealous as they used to get more students.

But Hakuji prevented them, fought them, defeated nine people, and eventually made them apologize to Keizo and told them never to look back to this Soryuu dojo or Koyuki again.

After that, the rivals apologized to let Soryuu Dojo in peace and promised that they would never harm Koyuki.

Hakuji’s Tragedy which turned him into Akaza

After this, two years had passed, and Koyuki’s health had improved significantly. The love blossomed between Hakuji and Koyuki.

Hakuji was now teaching the students in the Soryuu dojo, and it became popular locally, and more and more students eventually visited the Soryuu dojo to learn skills from Hakuji.

Then one day, Keizo offered Hakuji the proposal he said to Hakuji to take over his Dojo and marry Koyuki. Hakuji agreed and promised him that he would take care of Koyuki for the rest of his life.

Then in the festival, Koyuki told Hakuji about her past and ask him if he was ok with the proposal, and he also reaffirmed his vows to her and promised her that he would protect her with all his life.

Then rival Dojo heard about Hakuji’s marriage with Koyuki, and he was furious; he gathered some students from his Dojo and tried to fight Hakuji, but they lost.

Then starts the sad part of the entire story; after the whole incident with the rival Dojo, a few days later, he visited his father’s grave to get his blessings and show him that he has chosen a good life and was about to be married with the love of his life Koyuki.

Then soon after returning to the village, he sensed something wrong. He could feel that something must have happened while he was gone then one of his students tells him that the rival Dojo that he defeated had poisoned the well from where Koyuki and Keizo used to drink water from both of them are dead. This all happened while Hakuji was out of the village.

Hakuji, after hearing this was heartbroken. The person who gave him a good life and the girl he loved with all his life was no more.

Hakuji was no longer normal at that time. Maddened by the whole situation, he killed all 67 members of the rival Dojo, including the owner, with his bare hands.

He made sure all of their corpses are also not recognizable; this news caught the attention of Muzan Kibutsuji, whom we all know is the main antagonist of Demon Slayer.

He soon goes to the scene and witnesses what havoc Hakuji had caused and decided to make him one of the Twelve Kizuki.

Hakuji now had no one to protect the love of his life was gone, and his father figure Keizo was also no more, so he accepts Hakuji’s offer and becomes one of the strongest demons of all time, the Upper Rank 3 Akaza. This is how Hakuji turned from a normal human being to a demon.

The Most Powerful Demon Moons Ranked in Demon Slayer

Who Beats Akaza in Demon Slayer/Kimetsu no Yaiba?

Tanjiro and Giyo beat Akaza at the much later stages of the manga; during the “Final Battle Arc,” Tanjiro and Giyu Tomioka, also known as the Water Hashira, meet Akaza within the Infinite Castle.

This final battle was one of the most memorable battles in the mange of Demon Slayer or Kimetsu no Yaiba.

In this battle, Giyu was able to awaken his Demon Slayer mark, and Tanjiro used Hinokami Kagura (the dance of the fire god, which is only known to the Kamado family).

The powerful technique was used with Tanjiro’s Transparent World technique, and through this, they were able to cut off Akaza’s head in half.

But despite all of that, Akaza fought on with only his head, but while he was attacking Tanjiro and Giyu, he started recalling memory before he was turned into Demon by Muzan.

He started to recall his real name Hakuji the struggle he did to provide medicine for his sick father. He remembered the violent beatings he took from the magistrate, the unfortunate death of his father.

He remembered how he met Keizo, then Keizo gave him shelter and food while he was asked to take care of his ill daughter. He recalled the moments he spent with Koyuki, how he fell in love with her.

He recalled all the moments they spent with each other in the local firework show the time they reaffirmed their vows to one another, then, at last, he remembered the horrifying death of his lover when he went to his father’s grave to get the blessing for the new chapter he was about to start with Koyuki.

When he returned to the village, he remembered that he was given the news that his loved ones are no more and how the rival dojo owner poisoned Koyuki and Keizo. 

Also, he remembered how he took his revenge on the 67 members responsible for the death of his loved ones; he also recalled the moments with Muzan how he was turned into a demon by him.

Akaza finally realizes that all this hatred was because he couldn’t protect his loved ones, and fate was cruel to him; he lost everyone he had ever loved.

He was not able to be by their side at crucial times when it was needed. In the fight’s final moments, we see Akaza acknowledging the defeat and started attacking himself while Muzan urged him to fight with his demon side.

Finally, Akaza listens to his humanity and meets his father, Keizo, and the love of his life Koyuki. His loved ones meet him and welcome him to join them in hell, and then with flames swirls Akaza, now finally he becomes Hakuji and dies with that his demon body also crumbles away.
