A long time ago in the time of the Egyptian pharaohs and queens there was a Jackal Beastman by the name of Anubis.

He ruled over half of the empire of Egypt making humans his slaves and was known as the pharaoh ruler of his subjects the Jackal beastmen. No human was ambitious enough to stand up to Anubis or stop him.

Anubis held possession over a very powerful artifact known as the Beastman scepter which had the power to change normal humans into beastmen if needed but in the wrong hands it'll be used for greater evil. No human dared to go near the scepter until one human slave more ambitious then all the rest named Alan Sylvasta dared to enter into Anubis's palace as he found a potion to give him eternal life in immortality.

The young human slave drank the elixir of life not only making him immortal but transformed him into a powerful Cerberus Beastman.

After drinking the elixir of life Alan snuck into Anubis's throne room while Anubis was fast asleep and transformed into a big golden Cerberus and killed Anubis in his sleep stealing the throne for himself and now having power over Anubis's jackal Beastman subjects now in possession of the Beastman scepter and making all the Beastman in the kingdom bow before him.

He then released the human slaves and declared war on the beastmen with the humans following his orders.

A deadly war was set on the beastmen around the Egypt and England killing all the remaining Beastman in Egypt then Alan sent the humans to England to destroy the beastmen that lived there. None have survived and with the Beastman scepter in his possession he had power to rule over both humans and beastmen alike as a tyrant ruler.

The only surviving Beastman left was a ordinary wolf Beastman named Ogami who fled to try to save himself from Alan Sylvasta's army of humans but Ogami was shot down and killed by Sylvasta with his corpse lying there. Till something extraordinary happened as the spirits of his fallen comrades gave him the power of immortality turning him in the the mighty silver wolf.

Ogami as the silver wolf killed all the humans in the army in rage of the loss of his fellow beastmen. Unfortunately he didn't stop the leader of the humans known as Sylvasta. Tormented by anger, revenge and grief he continued to live on to protect the well being of Beastman from the humans but ever since the Second World War he still was unable to find the leader of the humans that nearly killed him that day on the battlefield.

Eversince that day Ogami feared his own powers so he sealed the power of the silver wolf away and vowed never again the reveal his secret as the silver wolf to anybody till that day he met Michiru a former human who became a Tanuki girl Beastman and the rhino Beastman Yama losing control and causing chaos in Anima city with him still fighting the out of control rhino Beastman Yama alongside the help of Michiru Kagemori with her special ability to Shapeshift but to still get nearly crushed by the monster's massive hands and Ogmai's injuries real serious.

Shirou Ogmai knew this was it he had to do it but he was reluctant to release the power of the silver wolf within him as he pulled off his collar and transformed into the real silver wolf.

Silver wolf Ogami sliced the monsterous creature into pieces and saved Michiru's life.

Later after he changed back into his human form after the fight Barbra Rose came and saw Ogami in his condition as she helped him get back on his feet.

"She knows about me," he said as the mayor of Anima city took him back to get treated.

When Michiru said those words she found out that he was the real silver wolf not her best friend Nazuna.

Later after Nazuna realized she was being used by Boris she stood up to him to reveal who she really is and fought alongside Michiru and her friends to stop a manifestation of out of control beastmen all over Anima city only to find out that it was Alan who was behind all of it, Michiru and Nazuna becoming beastmen, the cures and the out of control beastmen all together later to find out that Alan was also a Beastman taking on the form at first of a anthromorphic dog then matching Ogami's strength as the silver wolf by becoming a big powerful golden Cerberus.

It was a one on one battle the silver wolf Vs the golden Cerberus one attack cancelling out the other when Ogami looked in Michiru's eyes and decided to do what he could to protect her and the well-being of humans and beastmen alike.

The battle was intense till Ogami getting Alan right where he wanted him as Alan was losing control to think he was too pure to lose control as Ogami punched him but instead of killing him he decided to let him live after his defeat of out of control aggression and fear of the silver wolf Ogami.

After Alan's defeat he was not gonna be seen for a while as he had to be sent to trial in court but when the court heard the truth about how he lived as long as he did and was actually a former human who powered for revenge on the beastmen who inslaved him many centuries ago Barbara Rose felt like he should have many years behind bars for his hunger for power and vengeance and especially using Michiru and Nazuna as his plot device to turn all beastmen into normal humans.

Barbra Rose told Ogmai and Michiru the whole story about him being a former human gaining the elixir of life to turn himself into a powerful Beastman for his desire for power and vengeance against all beastmen and making the humans become his followers even trying to play nice with Michiru and her friend Nazuna to get them to follow him as well.

Michiru never thought at first that Alan was a very hateful person that turned himself into a powerful Beastman so many centuries ago to seek revenge.

Michiru never really wanted to become a Beastman but she also didn't want to show such hatred towards those who were different even though at first she thought all the Ogami was doing was just showing true hatred towards all humans when it was the other way around with the former human Alan who only cared about vengeance.

"When I was just a normal wolf Beastman when I was about to die I saw Alan hold some sort of staff possessing some sort of power to control all humans and beastmen," said Shirou Ogami.

"You know about the Beastman scepter?" Barbara Rose said.

Ogami nodded.

"What's that?" Michiru asked still not knowing much about Beastman history.

Barbara rose found a book and opened it up to show a picture of the scepter.

"This is the Beastman scepter, once owned by a powerful Egyptian Beastman pharaoh named Anubis whoever had possession of it could bring on great good or terrible evil depending on who held the scepter," Barbara Rose read aloud.

"Wow, that sounds like a real powerful artifact," said Michiru.

"It is and Alan used to have it many centuries ago," said Ogami.

"Where is it now?" Michiru asked.

"In the Anima Natural History Museum Instatute," said Ogami.

"But it's protected by high security, so hopefully nobody can get past that security system," said Barbara Rose.

"Oh good," said Michiru.

"Not only that but it has the power to turn humans into beastmen and beastmen into humans, so it cannot leave the museum," said Ogami.

"Gee, don't worry Shirou, Rose said it protected by a high security system, you worry too much," said Michiru.

"It's because my nose gives me a sinking feeling that something might go wrong," said Ogami.

Unfortunately Shirou was right that night when Ogami, Michiru and everyone else was asleep a sneaky ninja Beastman snuck into the museum slowly making it passed the tight security and opened the case to the Beastman scepter and slowly left with the scepter without setting off any alarms.

The burglar Beastman returned and used the scepter to set Alan Sylvasta free from his cell giving the Beastman scepter to Alan.

"There boss, just what you asked for," said the burglar.

"At last with this back in my possession nothing, not man nor beast can stand in my way, I'll be unstoppable!!" Alan said.

Alan snuck out of the police department jail and escaped to the Amin land to a city known as Ville to go use the Beastman scepter on the first human in the city in the mainland.
