A strange entity named Shoggoth was suddenly summoned by Chaos. The young Vampire Dragon felt surprised by its overly affectionate acts and then discovered that "she" was able to speak, calling "herself" as Abyss.

And as Chaos named her Abyss as well, she was given such a name, which came accompanied by millions of Mana that emerged from his body like black fog, filling the slimy creature named Abyss with power.

"Abyss… It is a strange name- Ah! Lord Chaos, how much mana did you gave to her?!" asked Belphegor in shock, as the blazing skull glanced at the black slime coated with eyes and a disfigured mouth overflow with power!

"Only 50 million I think… Ah, it is recovering fast thought," said Chaos, as he saw how he was recovering a few million mana per second.

"50 Million Mana is a lot!" cried Belphegor in surprise, as Chaos left Abyss over the ground, glancing at her change and mutate.

Abyss' slimy, black-colored body began to shapeshift, growing bigger in size and extending upwards.

Chaos realized that she was suddenly taking a humanoid shape… or something.

Part of her torso formed, and so her hands extended out of it, then came her head, and hair.

Afterward, her various glowing yellow eyes opened once more, as two of them emerged in the middle of her black-colored face, a smile also emerged, and even a few human-like features, making her resemble a… slime girl! But a very grotesque one.

Her slime down below quickly separated into two legs, and then the complete figure of a girl around her late teens showed up in front of Chaos, sitting over the ground as her slimy body twisted around, her various eyes spread through all of it glared at him, Chaos could notice that there was some kind of very unhealthy fascination held within such a gaze… But he didn't mind it.

Ding!

[Congratulations! Your Summon [Shoggoth (Phantasmal+)] has evolved into [Shoggoth Maid (Phantasmal+++)]!]

[All of your summon Stats have increased!]

[Your summon has learned new Abilities!]

After Abyss performed what seemed to be evolution, the system alerted Chaos that she had gained new Abilities and Stats as well.

"Hello, it seems that you evolved…" said Chaos.

Abyss slowly stood up, as Chaos helped her by giving her his hand.

However, she used her black tentacles to entangle his arm and reach to his chest, entangling him with the slime that would be her legs, resembling black and oozy tentacles, while her upper torso hugged his head.

"Eh?"

Chaos was then smothered by Abyss's bouncy pair of peaches, albeit they were merely her slime, they now had some kind of bounciness and heaviness that differentiated it from mere slime.

"Master…! Master!" she said, with a rather adorable voice.

"You can call me Chaos…" sighed Chaos, as he tried to move her away from his chest, but because she was all slimy, it was very hard, his hands kept diving inside of her oozy body without reaching anywhere.

"Chaos! So that's your name! It is… the same as Abyss, me! You're using the name they gave us… Right?" she asked. She was slowly managing to speak more fluently.

"Huh? Wait…" muttered Chaos, as he suddenly realized that she knew way too much about his past for him to feel comfortable with.

"What do you mean?" he asked.

"I know you! Even with your appearance… changed!" said Abyss with a cute smile, as all the eyes of her face seemed very expressive compared to the ones over her body.

Chaos couldn't help but pet her head gently.

"You're a gentle girl, but I really don't understand," said Chaos.

"Well, it doesn't matter! Someone sent me here, for you! I want to protect you! And I will! So let me… protect you!" she said, as she approached her face to Chaos and kissed his nose adorably.

"Oh, my lord, she seems very eager! Good! Abyss, let me introduce you to the rest of the facility then!" said Belphegor, as Abyss completely ignored him, she didn't want to avert a single eye from Chaos.

"Someone… Who?" asked Chaos.

"I don't know…" said Abyss.

"Hmm… Well, it is better to not annoy you with this for now…" sighed Chaos.

Abyss smiled cutely, as she hugged Chaos again.

"Will you stop hugging me?" asked Chaos.

"I don't want to…" said Abyss.

"…Okay," said Chaos, as he decided to walk at the side of Belphegor. Noticing that Abyss ignored the blazing skull, so he had to show the castle to Abyss and give her a brief introduction of everything by himself, although Belphegor also spoke in between.

"Lastly, this is my throne. I suppose… This place used to be of my father, but it is now mine… I am still trying to cope with everything," said Chaos, as he sat down over the throne, while Belphegor suddenly brought a strange dress with black and white colors.

Abyss glanced at the dress as she smiled happily, finding it cute, and finally stopping to ignore Belphegor.

"Hahh… This is it! I brought this because you said her evolution was Shoggoth Maid, so perhaps she could get some kind of enhancement if she wears maid clothes. We once used to have Maid Zombies and Maid Ghosts… but they died protecting the castle alongside Master Ainz. Perhaps Abyss could be our first Maid after a long time," said Belphegor.

"Ah! Thank you, skull!" said Abyss, as she grabbed the long and traditional maid dress that quickly wore it, looking rather cute, which made Chaos glance at her with intensity, but because he was expressionless and stiff, he seemed to be glaring behind her than directly at her by how uninterested his expression seemed to be, despite actually finding her cute.

"M-Master, do you like it?" she asked.

"Yes, I think you look very cute, Abyss," said Chaos nonchalantly, he didn't even stutter to praise a girl's beauty. Although deep inside he was nervous to say such a bold statement, but in the end, it came out rather flawlessly.

"Hehe… I-I am glad that you like it, Master Chaos!" said Abyss. Chaos felt intrigued about her origins and began to think that she might originate from his same Earth, especially because she seemed to somehow recognize him despite the change in appearance.

He also felt a strange and unique connection with her between both of their souls, it was as if she was given his power even before being summoned here.

Chaos began to speculate that this girl might have been somehow related to him in his past life, or that something happened to her that ended making her so familiar to him.

Some of his hypotheses, from what he had heard from the scientist, was that she could have been a guinea pig such as him and that they used his miasma to experiment with her body…

Although this was a mere hypothesis, Chaos should praise his amazing insight, as this was actually the truth.

However, he decided better to not speak about this for now, as he didn't want to bring back bad memories of his past, nor those of Abyss if she ever had some.

For now, he decided to call all the monsters of the castle, as he decided to "upgrade" them by feeding them large amounts of Mana and Miasma, and also he planned to get out of the castle for the moment and explore the area, as he had heard by Belphegor's words that there was a dungeon nearby.
