Today was different I found. What was different? Well, we were leaving the Gremory estate… for something. They didn't elaborate on where we were going, but I had the oddest feeling about it. That may be simply because it would be the first time I left the castle since my arrival… and I was both nervous and excited. Nervous because I had little idea of what to expect and excited because I might see some cool magic stuff.
Cool magic stuff usually overrides most things I feel.
I was dressed in spiffy clothing as always, and Rias was in a cute dress. She held my hand as we followed after her mother and Grayfia to another part of the castle. We entered a room that held an ornate magic circle.
Venelana waved us over and knelt, "Alright, I trust you two will keep this a secret, okay? We aren't supposed to have a teleportation circle that goes straight into Lilith, especially into the capital buildings."
Rias tilted her head, confused, "Then why do we have it?"
Grayfia answered with a sigh, "Lord Lucifer requested it despite security concerns."
Venelana giggled, "Ufufu, that son of mine is quite the worrywart at times."
Rias blushed a little bit as she recalled… her brother, presumably? Venelana did refer to him as her son despite Grayfia referring to him as lord Lucifer. And wasn't that a title? Lucifer, as in the biggest bad, and The Devil himself?
…I suddenly felt that I may have been picked up by more than simple nobles. Sure, they may be devils, but I didn't think they were directly related to the fucking Demon King himself!
… I suddenly came to a dire realization. Grayfia… is married to Rias' brother.
Then that means …I've been getting handjobs from the wife of The Fucking Devil for a month!
It was at that moment I decided to pass out, unable to comprehend just what kind of situation I ended up in.
As I slumped over, I heard Venelana say, "Oh, dear, looks like he's a little sleepy. Well, this works out in our favor. Give him here, Rias."
In my last fleeting moments of consciousness, I was pressed against Venelana's wonderful tits. At least something in this world made sense.
__________________________________________________________________________________
Ajauka Beelzebub looked at his patient, a tiny goblin… who was still unconscious as he slept curled against Venelana's bosom. When he received the call from her yesterday, he didn't think much of her request… but when she mentioned the extinct Shax clan. Well, he was a tad interested.
Now, however, he was curious for another reason. But first, he waved his aunt in all but blood to lay the goblin on the examination table. She did so, and Sirzechs sister walked up to him and nervously asked, "He's going to be okay, right Lord Beelzebub?"
He knelt down and smiled at her, "Do not worry. Even if something is wrong, I will help him."
She sniffled, and he produced a lollipop from his coat and handed it to the girl. She brightened up a bit and walked over to her mother while enjoying the treat. He had procured a few treats for today's examination as rewards made for happier test subjects… or rather patient in this case.
He stood up and looked at the… interesting specimen that graced his table. The goblin was doing something interesting. Perhaps not consciously, but interesting nonetheless. Ajuka was rather attuned to his environment thanks to his particular abilities and he had noticed immediately that the goblin was doing something.
And now it was time to find out.
"Ajuka."
He paused as Venelana spoke up. She then gave him a look he hadn't quite seen in some time. One of warning, "I know that look, young man. Don't get too invasive."
Ah, now he was a tad embarrassed. When was the last time he had been admonished for his particular habits? Some centuries ago, if he was right. It was a bit nostalgic and refreshing. Nowadays, just about everyone folds under his power and reputation. It's nice to know that Venelana would still treat him like a child.
He smiled, "Very well."
His magic circle spun to life, and then he observed the goblin.
Oh, that is quite interesting. With a better look, he can see that the goblin is passively absorbing energy from his surroundings and assimilating them. Similar to the Sage Arts… but with everything rather than natural ki.
Light, heat, radiation, and, of course, a variety of magical energies were taken in and assimilated.
How fascinating.
While the energy absorbed was minuscule, under the careful gaze of his Kankara Formula, all was revealed. He looked deeper and saw there were extremely small reactions occurring as he absorbed energy. His internal magical energy would heat up, brighten, chill, and a dozen other things. Normally this would be cause for concern… but the scale at which it happened was so small that it didn't negatively affect him.
If anything, it was good for him. The nature of his magical energy was in constant flux as with each passing second he could feel affinities develop. Very, very minor affinities, but the fact they were developing in the first place was so very fascinating.
From his observations, he did get an idea of what was happening. The assimilation process wasn't free. His magical energy had to vie for dominance and tame the foreign energies. What could be gathered passively was minuscule and he was suddenly very curious if the goblin could actively use this ability.
Perhaps he could gain a few insights that he could use for his own work.
He wanted to perform a few experiments.
He got another look from Venelana, and he calmed himself.
Apart from his fascinating absorption ability, the goblin was healthy… if small for his apparent age. Ajuka had a little theory about that as well. The goblin's body felt… malleable in a way. It was similar to the shapeshifters he had encountered before.
His magical energy was also much more potent than any goblin that he had examined before, but that could be tied to his unusual ability.
Then there was his Demonic Power. It wasn't much when compared to a proper devil or half-breed… but it would fit if he had devil ancestry.
Who would mate with goblins, of all things?
He shook his head and decided to share his findings, "Well, there appears to be nothing wrong with him."
Venelana narrowed her eyes, "But?"
He smiled, "But he has a peculiar ability to absorb and assimilate energy."
Before anyone could speak, he rubbed his chin in thought, "It actually reminds me of some research I did on goblins before. You see, goblins' genetics are extremely adaptable. You could throw a standard goblin into a new environment, and in a single generation, they would begin to develop adaptations to fit in the new environment."
He gestured to the goblin resting on the table, "What this goblin is doing is perhaps that adaptability taken to the theoretical maximum," he then hummed as the pieces came together, "Hmm, That would fit with how malleable his body is. Once he reaches a certain threshold or outward stimuli his body would likely change to accommodate. Quite the fascinating quirk of nature he is."
At that, Grayfia furrowed her brow in confusion, "So is he like yourself and Lord Lucifer and some sort of… Super Goblin?"
Ajuka raised a finger to protest but lowered it a moment later, "That… that would not be an incorrect term. A Super Devil is a devil whose abilities are far beyond that of a normal devil… and I suppose his ability is far beyond any ordinary goblin. So Super Goblin it is, then."
Little Rias made her presence known at that, "Gobugobu is a Super Goblin! That's so cool!"
The little devil had stars in her eyes as she looked at her familiar with amazement. That was when he noticed the goblin stir.
The small goblin looked at him and promptly… faded from his vision? He could still see the goblin, but he looked a tad see-through.
That was when Venelana spoke up, "Ah, this is what I wanted to talk to you about. He seems to be able to do that on command," she then smirked, "Does it remind you of anything?"
He furrowed his brows as he attempted to recall something. Then he was suddenly reminded of her earlier call, and he spun on his heel and pointed at her, "The Shax!"
Venelana smiled as she walked up to the goblin, "Yes, it is very reminiscent of the Shax's clan trait, isn't it?"
The goblin calmed down and returned to full clarity. He looked a bit confused but was silent.
Ajuka then paced back and forth a bit, "I have never met any of the Shax as they were long since purged by the time I was born. But I have read up on their clan ability. Presence Concealment that can even fool God as they so proudly declared."
Rias winced slightly from his declaration, and he apologized, "Sorry about that."
The little devil waved him off, "I'm a strong girl, so it's fine."
Venelana then laughed bitterly as she held the goblin up, "Not that their ability helped them much back then," she shook her head, "But that brings me to Gobu-chan. I think he might have that ability."
Ajuka rubbed his chin in thought, "It would explain his Demonic Power if he was descended from a Shax devil and the union of a… goblin."
Oddly at that, Venelana and Grayfia flushed slightly. How strange.
Grayfia then asked, "Does this make him a devil then?"
Ajuka shook his head, "No, the devil blood is likely extremely thin, and he likely only has access to Presence Concealment thanks to the mutation that makes him a Super Goblin."
Said goblin tilted his head and said, "Super… Goblin?"
It was then that little Rias ran up to her mother and looked up at her familiar, "Yeah, Gobugobu, you are so cool! You can suck in magic and ass- assim-"
"Assimilate it," he finished for her. He then looked at the goblin once more, "You may not understand this at the moment, little one. But you have quite a peculiar ability. You can take in all manner of energy and make it your own," he then leaned in, "But do be careful. You may injure yourself if you take in too much energy. Don't want to burn yourself up from taking in too much heat, yes?"
The tiny goblin slowly nodded and he got the feeling there was quite a bit of intelligence behind those eyes.
He smiled and produced a lollipop, "Now, here you go for being a good patient."
He grabbed the offered candy with his small hand and began to suck on it happily.
He then asked Venelana, "Now then, I can have a more conclusive report if you will allow me a few tests. Nothing too invasive. Just a blood sample and to see if he can actively use his absorption ability."
Venelana eyed him for a moment and then looked down at the goblin within her grasp, "Gobu-chan, do you want to do the tests? I won't make you."
The goblin made a noise of affirmation and gave a thumbs up.
Ajuka smiled, "Well, I suppose that answers that?"
Time to begin the tests.
_____________________________________________________________________________________
Waking up from having my meager worldview shattered in what had to be a mad scientist's lab was not great. Learning I was some sort of Super Goblin, on the other hand, was great.
If I didn't know better, then I would assume I'm the protagonist of some sort of Isekai. However, given my master was the sister of literally Satan, it was far more likely I was just the cool pet of the protagonist… or love interest. I refused to think that my cute master would be relegated to love interest! So Rias had to be an Otome protagonist. She fit as the cute but powerful dork who would pull in all manner of people who would fall in love with her.
While I was relegated to the role of a pet. With hard work and effort, I could be the cool butler of the protagonist.
Butlers are cool, and they get cool fights.
All those thoughts rumbled in my head while I got my blood drawn by the mad scientist. Oh, he may not look like a stereotypical mad scientist but something in my bones told me this guy can make some crazy shit.
At least he had good taste in candy.
I rolled the lollipop around my mouth as he set up the test of my absorption ability, as he called it.
The mad scientist then held up a finger, and a small marble-sized sphere of green energy appeared at his fingertip.
"Alright. Now, I want you to touch this and focus on taking it into your being. This is healing energy, so it shouldn't have any adverse effects on you."
I lifted a hand and tapped the sphere, and I did as I was told. I closed my eyes and focused. My eyes then opened as the sphere broke apart into streamers of light and flowed into me.
I blinked as I felt rather good.
The mad scientist nodded, satisfied, "Good. But I want to do one more test," this time a weak flame flickered on his fingertip, "Now this one is fire. So you may feel some warmth as your magical energy attempts to suppress and assimilate it."
I nodded and tapped while I focused. Like last time, it burst apart into embers and floated into me. I then grunted as I suddenly felt very warm. It passed after a moment… but I could tell that it could have been much worse if he had used something stronger.
It looked like my cool power had some drawbacks.
The mad scientist smiled once more, "Good, very good," he then turned to Grayfia, "Ask whoever handles his education to start including magic lessons. He has some excellent potential."
Grayfia bowed, "Then I will add it to my lesson plans."
The mad scientist paused and then smirked, "I see," he then turned to Venelana, "Now I ask that he come in for the occasional check-up. I wish to see his development, and if anything strange happens, I would like to know."
Venelana smiled and looked amused, "You will have to ask his master that, Ajuka."
His adorable master simply smiled, "As long as he's happy, I'm happy!"
The mad scientist then turned to me, "Very well then. Would you be fine with coming for later tests? I would like to see how far your abilities can go."
On one hand, mad science… on the other, possibly learning cool things about myself.
Cool stuff wins, and so I nodded, and the mad scientist looked satisfied.
"Very good. Then I hope to see you soon, Oh, and have one more for the road," he then handed me another lollipop.
Venelana picked me up and bowed slightly at the mad scientist, "Thank you for your help… Lord Beelzebub."
… The mad scientist was another Demon Lord! Are you kidding me?
I give up. I curled against Venelana's magnificent mammaries and decided to take a nap.
Hopefully, the world would make sense when I woke up back at the castle.
