After completing their most recent experiment, Satanael and the Wizards of Oz organization returned to the research institute they were using as a base.

The location of the institution was an ample, pre-prepared space that had been established underground beneath one of Japan's urban areas.

The site had not even been reported to the people of the "Utsusemi Agency". Those who could enter and leave now were only the personnel authorized by Satanael, as well as the Wizards of Oz.

From the beginning, the Agency people had been used as sacrificial pawns.

With the data from the time they had been manipulating the "Utsusemi Agency", together with the cooperation of Augusta, they had achieved the result they had been aiming at without any problems.

On returning to his own personal laboratory inside the institution, Satanael opened the cap of a cognac bottle that had been placed on the board, from which he poured some into a glass.

The moment he took a sip, several mages entered the laboratory.

They were mages with some leadership within the side of Oz.

"So you have returned, Satanael."

Having received a greeting from one of the mages, Satanael says.

"I assume you are aware of the matter concerning Augusta."

Even knowing that the Wizard of the East, who was one of their leaders, had perished, the Wizards were not at all concerned.

"There is still the candidate for Wizard of the East. It's very nice that it was possible to recover the purple flames."

The Longinus of the Flames, which had been lodged inside Augusta's body, had been recovered by her disciple Walburga and had been taken back to this institution.

"No, he has let her recover the purple flames."

Who Satanael was referring to, the witches didn't know. However, it was clear to Satanael that, with the alignment they had prepared for that night, probably all the enemies of the strange robe organization would have been eradicated if that man had so decided.

Why had that dragon let Satanael and Walburga escape?

Satanael did not know, but he was only excited to face such an unpredictable opponent.

Walburga herself was in this room, she had been looking curiously at the experimental equipment in the room.

In terms of the death of Augusta, her teacher, her state was one of total lack of concern.

"Were you able to get in touch with that side?"

"Indeed. It seems that the "Emerald City" has woken up considerably. After all, we may be able to achieve our goal of using the Three Demonic Beasts again."

The Three Demon Beasts of Oz were: the lion with no courage [Cowardly Leo], the metal man looking for a soul [Dead Lumberjack] and the brainless scarecrow [Rampage Scarecrow].

Once again, using them had become the only goal publicized by the people of Oz. If this was their only target, Satanael didn't know it, and he didn't care.

One of the Wizards turned her gaze to the corner of the room. There was a single long sheathed sword sleeping in a capsule for exclusive use.

"Could that be a demonic sword?"

In response to the Wizard's question, Satanael stood in front of the capsule being fitted.

"It seems that among our opponents there are several who carry problematic "swords". So, when I slipped away from Grigori, I simply thought of something I could take with me that would be useful."

As he tapped the capsule with his finger, he said.

"Arondight. The only legendary sword which falls from a sacred sword into a demonic sword. With this, either the sword of Longinus or if it is that woman, I should be able to exchange a few blows with them. Above all, it is suitable for an angel who has fallen like me."

Not only that, but this sword is considered a Dragon-Slayer. More than one of Satanael's opponents are dragons, or their powers are related to them.

As they turned their eyes to the sacred sword that had fallen, the Mages asked Satanael.

"So, what about the previous target?"

"To invoke disturbing elements, power is necessary. If it's a human, it's okay as long as they've been given Sacred Gear, but as far as fantasy beings are concerned, it's a different story. When it comes to attracting fantasy beings, power as an explicit offer is necessary."

"So that would be your goal?"

Satanael looked at the wall of the room.

That place... was decorated with a painting of a long black dragon that was like a snake. The dragon held its own tail in its mouth.

Satanael says.

"The longest living creatures in the world: dragons. Among them, who is said to be a Dragon God, is one endowed with the power of infinity..."

The Mages understood.

"Uroboros, huh. The power of the "Serpent" of Uroboros..."

"In fact, my target is Ophis."

A legendary dragon. The Dragon God considered the strongest in the world.

The being who was the personification of infinity. Satanael had decided that the strongest dragon was his target.

Walburga posed a question as she extended her hand to a fresco in the corner of the room.

"By the way, what is the name we are giving this gathering of forces?"

"Put a name on it, just call it what you want."

One of the leading Wizards sharply rejected the statement of the young Walburga. However, Walburga, not caring about anything, asked a very interesting question.

"But, but, isn't something like this of considerable importance? Shouldn't we give it a name like those of the opposing powers?"

To this, Satanael responded.

"If it's a name, I've been thinking about one."

After a moment's pause, he said that name.

"Khaos Brigade, I think that's what we should call our meeting."

It all started from here...
