Shuten-douji was not very strong when he first appeared, and was driven away by humans using ordinary spears and cannons.
On the way to escape, he met the Ghost Lord, a very thin ghost tribe. When he was stealing salted fish, he was almost beaten to death by the villagers with hoes and axes.
Shuten Doji easily rescued him and adopted him as his younger brother.
In this way, the ghost master became Shuten Doji's first younger brother and fled everywhere with him.
During the journey, they had conflicts, laughed, talked about their dreams at night, and faced enemies side by side, supporting and helping each other along the way.
Although the relationship is nominally superior, they are actually deep friends and brothers.
They gathered a large number of monsters on the road, and finally built a cast-iron palace belonging to monsters in Hokkaido. They fought side by side and repelled human attacks many times, and gradually became stronger.
When they came back to their senses, they had transformed from the two downtrodden monsters they were being chased into, to a giant monster that commanded tens of thousands of subordinates and made humans fearful. They had completely established a foothold in this world ruled by humans.
Shuten Doji and Oni Lord thought they could coexist happily like this forever.
But it turns out they were all too naive.
It is impossible for any organization to be intimate with each other. This is true for humans, and it is also true for monsters.
When external conflicts are suspended, internal conflicts begin to emerge.
The first conflict between Shuten Doji and the Oni Lord was the development direction of the Iron Cast Palace. The two sides had serious differences in their routes.
Shuten Doji always remembers the humiliation of running away when being driven away by humans. His goal is to lead the monsters to occupy the entire 11th area and kill all the humans. He cannot wait for a moment.
The Ghost Lord believes that the Iron Palace needs to develop peacefully and accumulate strength. The monsters have suffered heavy losses and are exhausted from resisting the human attack. Shuten Doji's goal will only drag the Iron Palace that was finally built into the abyss.
The two sides had numerous quarrels over this issue and could never compromise.
The second conflict between the two sides was the tyrannical rule of Shuten Doji.
He likes to eat people and uses virgins as food and drinks. The ghost owner does not object to this. After all, monsters and humans are considered hostile races.
But Shuten Doji gradually began to attack monsters, and his methods were so cruel that even the most perverted monsters could not stand it.
During his reign, there were even monsters escaping to the human side of the Iron Palace.
The third conflict is that the trust between Shuten Doji and the ghost master begins to crack.
The ghost master is extremely capable, and all the monsters in the Iron Cast Palace are convinced by him. However, Shuten Doji has long lost the spirit of monsters due to his tyrannical rule.
Shuten Doji was worried that the ghost master would replace him, and suppressed him many times regardless of the relationship between the two parties, making the brothers who were originally close to each other become suspicious and hostile to each other.
In the end, the unbearable ghost master teamed up with the big monsters of the Iron Palace to poison Shuten-Dōji's wine, and then found Tsuna Kiri Yasu, the boy who was said to be able to kill Shuten-Dōji.
At the top of Sounkyo Gorge, the betrayed Shuten Doji finally died under the sword of the boy Kiriyatsuna.
"I will come back and take revenge on you with my own hands."
After saying these words to the ghost master before his death, Shuten Doji's body sank into the Lake of Heaven with the boy Kiri An Tsuna, and no one could find it.
Decades later, Shuten-dōji was reincarnated into the body of Onitakizawa, the second son of the Oni Lord.
When he was young, he had not awakened the memory of his previous life, but he had already performed extremely well, making the ghost master very happy, thinking that he had obtained an outstanding successor.
But when Oni Takizawa gradually revealed a similar appearance and temperament to Shuten Doji, Oni Lord finally recalled the words Shuten Doji said before his death.
He realized that Oni Takizawa might be the reincarnation of Shuten Doji, but in the end he did not kill Oni Takizawa. Instead, he sealed all the power in his body and ordered Gekko Hoshiki to monitor him.
Shuten Doji's past life memories gradually awakened. After his power was sealed by the ghost master, he immediately changed his original personality and remained peaceful for more than ten years, deceiving everyone around him.
About ten years ago, the ghost master came back seriously injured after going out. The injury would relapse every once in a while, and he had to hide in the iron palace to recuperate.
Onitakizawa took advantage of the relapse of his old injury to sneak into the Lake of Heaven and found the bones of his previous life under the mud, as well as the boy Kiriyasu Tsuna on the bones.
With the help of the boy Kiriyatsuna's power, he broke the seal placed on his body by the ghost master and recovered part of his strength.
Until the past month, the ghost master's injury recurred again and he died directly.
This made Oni Takizawa extremely disappointed. He had prepared a lot of conspiracies and tricks to take revenge on the ghost master, but in the end, he died in such a shameless manner.
"Didn't you injure father?"
Gui Yunji suddenly asked.
Ten years ago, the ghost master came back from a serious injury after going out. When the injury relapsed and he was in coma, he mentioned the name of the drunken boy several times, but he denied it when he woke up afterwards.
At that time, Oni Yunji thought that Shuten Doji was not dead, so she attacked and injured her father. When Oni's injury recurred and died, Oni Yunji regarded Shuten Doji as the enemy who killed his father.
But Shuten Doji had been disguising himself as Oni Takizawa and stayed in the Iron Palace without leaving, which meant that someone else had injured the Oni Lord.
Oni Takizawa came back to his senses from the memory of the past and smiled at Oniunji: "How could it be me? During this period, I have always been your dearest second brother, hanging out in front of you every day."
Oniunji felt cold in her heart. She had no defense against Oni Takizawa before. If he wanted to take action, he would have countless chances to kill her.
"Then what exactly are you going to do?"
Gui Yunji said in a deep voice: "Are you going to kill me and take back the throne that belongs to you?"
"No no no."
Oni Takizawa raised a finger and shook it: "I am no longer interested in the Iron Palace. One of the reasons why I still stay here is that I want you two brothers and sisters to kill each other to show the ghost master. It’s a pity that he died too early and couldn’t catch up.”
Before Oniunji could say anything, Umitsu Kaori suddenly interrupted with a cold tone: "So, you are the one who has been secretly targeting the Uguang family? It was you who ordered Okuyasu, and my daughter was almost kidnapped by a vampire. Is it also your handiwork?"
Fang Cheng, who was eating melon, didn't expect that he would have his own role, and then he realized that the vampire Umitsu Kaori was talking about was not him, but Kuroishi Yuto, who had captured Umitsu Mirai.
How come Kuroishi Yuto is related to Shuten Douji?
Fang Cheng looked confused, but Umitsu Kaori had no time to explain to him.
Yu Guang was kidnapped by a vampire in the future because someone secretly lured her bodyguard away. Otherwise, how could a vampire with no fur even grow out of her body possibly capture her.
Including the actions of the Aardvark to sabotage the peace talks, there must be people from the Iron Palace supporting them.
Umitsu Kaori has always believed that these things were secretly sent by Oni Rakshasa. After all, Oku Aardvark was the Oni Rakshasa's right-hand man before he defected to the Iron Palace.
This is one of the reasons why Oni Yunji is determined to fight to the death with Oni Rakshasa. Sabotaging the peace talks will destroy the development prospects of the Iron Cast Palace.
Now it seems that he may have been wronged by the ghost Rakshasa, and he probably doesn't have the brains to play such a complicated conspiracy.
