A meeting in the ice castle.

A few days before the Walpurgis.

.

In a land covered by ice where fierce blizzards reigned,

Its vicinity was covered in a barrier of ice, with temperatures of minus 120° Celsius such that nothing could live there.

Its presence testified to an unimaginable amounts of magical energy–truly a castle of the highest demon.

And it was ruled by Demon Lord Guy Crimson.

There was a being leisurely walking though the castle.

Skin so white that it was almost transparent.

Demon Lord Leon Cromwell. The one called the Blond Demon.

Ahead of him was a door with beautiful carved decorations. It led to the audience chamber of the lord of the castle.

Leon stood in front of the door, and the two large attendant demons opened it.

And,

''Demon Lord Leon Cromwell-sama has arrived!''

A female-like demon announced.

In this room was 200 named greater demon which easily surpassed A-Rank.

And before the throne was 6 incredibly powerful demons at the level of pseudo-demon lord.

And even stronger was the two "Demon officers" Mizari and Hirari.

And that's where Mizari and Hirari kneeled, and

「「Leon-sama, it has been a long time」」

At the same time they greeted Leon with a beautiful voice.

And after that only Guy and Leon the two demon lords had the right to move within the room.

After a few familiarities the two beings of incredible power sat down to discuss and Leon began by asking:

"So? Why have you called me?"

"Ah. Do you know about the upcoming Walpurgis? I was thinking that if you couldn't attend I'd have to make you attend."

"Huh? You know I hate these gatherings? But I was planning to attend."

"And what made you decide to participate ?"

"The Walpurgis this time is hosted by Clayman. I'm curious why Milim is supporting him and Karion's death is suspicious. At first it was because Clayman wanted to spur us on a subjugation, but then Ramiris requested that the party in question attends. In other words, everithing seems connected. So I feel the need to see, this new Demon lord Rimuru."

"So you believe he has the qualification to be a demon lord ? Well I fought the same thing. Ho, and for Milim she is surrely just playing around. No use trying to figure out what she think. And we do not have to listen to the opinion of Clayman but Ramiris' opinion, on the other hand, seems promising and if she found someone interesting I might enjoy myself even more."

" Ramiris... Well I'm no good with her. From the very moment we met I had thought to go and kill her a few times. And why do you say more ? Someone interesting is coming with any other Demon lord ?"

" Well if you kill Ramiris I'll be your enemy. And to answer your other question, no said person doesn't come with any of the demon lord but is a new demon lord just like this Rimuru."

"And who might that be I do not remenber anyone who had the potential to be a Demon lord for the past year ?"

"Hoh. She is already pretty known and was there since 50 years ago."

"You couldn't be talking about HER ? "

" I do think I am."

" How in hell did she become a Demon lord I thought she disappeared all this time ?"

" Well, it would seem she disappeared because she was beginning to transform into a True Demon lord. Which is quite funny, to think 2 True Demon lord appeared at the same Time."

"Well, It would seem you do not need me anymore so I'm gonna take my leave. See you at the Walpurgis".

Leon then left the castle going back to El Dorado. During this Guy was thinking:

' What a good day to learn that not only Leon is participating willingly in the Walpurgis but that she reached such strength, it truly is something I'm eager to see. Well I'll have to wait for the Walpurgis to see it. Maybe she even attained an Ultimate skill."

.

Back to the Walpurgis.

.

"What are you doing here?" asked weakling/already dead Clayman.

To which the unknown figure that ABSOLUTELY nobody know who she is. (Well everyone knows except the weakling Trio, the sons of Dagruel and Rimuru.)

"Well I asked Guy if I could come and as I am a bonafide Demon lord he axcepted and here I am well maybe a few minute late but, hey, its not my fault its the fault of the road."

While she was saying that everyone thought the same thing.

'You just got lost and do not want to admit it."

Clayman giving up and as she already had the permission of Guy he said to her:

" Well, if you say so. Take your seat. We are going to begin the Walpurgis."
