Adrien teleported to his room, and sat behind his desk again. A book flew out of one of the shelves and landed on the desk in front of him, then it opened on it's own and stopped on the page listing the ingredients for normal demonic poison.
"So where did I go wrong?" Adrien asked himself, he pondered for a few minutes searching his mind for any ingredients he might have missed. On his desk clay formed into a cup and water filled it from thin air. He took the cup and downed it in one go then refocused on the book.
The ingredients listed were: night shade petals, demon beast blood, demonic beetle shell and black serpent venom. Of course the measures were also listed, like how much he should put of each ingredient. For example if he puts a lot of venom, it would insta kill. or if he didn't put enough demon blood, there wouldn't be any reaction whatsoever.
Adrien closed his eyes and entered his mind palace.
A mind palace is a way to store memories in your brain by imagining a place, like a house for example. You place information in different rooms or spots so it's easier to remember. When you need it, you mentally walk through the place and pick the memory back up.
The place that Adrien chose as his mind palace was the library in the Agares estate and specifically the small library in the northern isle that he spent most his time in.
He walked in the library passing bookshelf after bookshelf. Then he stopped in front of drawer, he opened it. Inside were hundreds of files, each containing information about different type poisons. He rummaged through each file till he found a file titled 'demonic poison'.
"There it is" he whispered. He opened the file and started reading through it. When he got what he wanted, he placed the file back and opened his eyes, returning from his mind palace.
"So I should have put 0.3 grams of that beetle shell instead of 0.5... Tsk", another Erlenmeyer flask formed on his desk and just as he was about to start again-
Knock Knock Knock...
A knock resounded through his room, but no one entered.
'it must be a maid, anyone in the family would have barged in'
"Come in" Adrien said without looking toward the door. Like he suspected, a maid entered, she was one of the three maids placed under his service. She had long chestnut hair and hazel eyes, she wasn't exactly the beautiful type, more like cute with big round eyes and full cheeks.
The maid, Lynn, entered after checking the hall, and closed the door behind her
"Andyyy!!" She ran and hugged Adrien from the back wrapping her arms around his neck and pressing her cheek against his.
Lynn was an orphan that Adrien had took in while he was wondering around. Her parents were killed by a demonic beast that suddenly appeared from the forest near and rampaged in their village. Adrien who was 9 years old back then, had ran away from the island and just happened to be passing by.
He killed the beast and found Lynn who was crying outside her demolished house. He took her back with him and placed her as his first personal maid.
"Haaah-" Adrien sighed, "Can't you see I'm working?"
"I was worried... you were in trouble with Lord Agares..." Lynn answered in a soft worried tone.
Adrien never acted like a noble, so this personal maid of his was more like a childhood friend to him than a servant. So this situation was normal between the two of them, though Lynn always checked to see if anyone is watching. Adrien was still the son of the archduke and he couldn't be seen being overly friendly with her, even though he had told her that he didn't really care.
Adrien dismissed her worries, "Nah it's nothing, the Phenex are just crybabies"
"Yeah but aren't they like, super strong and influential. What if they go after you?" Lynn answered still slightly worried.
"I gave dad a potion that'll fix their problem, and they wouldn't mess with me with no real reason so they wouldn't push the matter too much"
"I hope so..." Lynn said as she approached a sort of large bean bag. "What is that? it feels comfortable, I've never seen anything like that before"
"Yeah it's nice, I stole it from France", Indeed, Adrien stole it the last time he was in Paris, he didn't have their local money so who could blame him?
"Stole it? You shouldn't steal stuff Andy!" Lynn scolded him.
"I'll just return it later when i get tired of it"
Lynn started lecturing him about ethics and morals, apparently she forgot they are devils. Adrien didn't hear any of it, he was back working on his electric potion of his. The second experiment failed again, the third one didn't explode but it had no effect.
An hour passed in trial and error until it worked, "Finally..." Adrien said as he stood up and swirled the flask in his hand, he turned to show it to Lynn but she had already left.
"Huh, when did she leave? Well anyways..." Just as he was about to summon a test subject, he felt an immense pressure hit the whole mansion, the suffocating pressure subsided then disappeared all together. "What an entrance"
'The fuck is going one today'
The flask in his hand disappeared into his dimensional storage in a swirling vortex. He walked out of his room, into a large hallway, a maid was on the ground, in front of her was a tray of food, it's content splattered across the ground in a messy mix of crumbs, sauce, and crushed pieces.
'She probably fell due to the demonic pressure'
When she saw Adrien she hurriedly started to clean the floor, he approached her and helped her up then with a flick of his fingers, the food stains on the ground disappeared. The young maid, blushing thanked him then ran away taking the tray with her.
Adrien continued forward and approached a floor to ceiling window, he looked outside toward the garden. On the pavement stood a tall man with shoulder length fiery crimson hair, his bluish eyes were looking straight at Adrien through the window, an amused smile tugged at the corners of his mouth.
'He got me' Adrien sighed.
He walked down the stairs of the mansion, then walked through the main entrance hall, Seekvaira was already there showing Sirzechs Lucifer, one of the four great Satans, in. Adrien stood in place looking at Sirzechs in annoyance, he on the other hand enjoyed Adrien's reaction to the fullest.
The three of them entered the main hall together, Seekvaira was talking with Serzechs and he was laughing softly. Adrien walked behind them, looking like he is being held hostage. Lord Agares stood up and bowed in a perfect 45 degree angle, hands behind his back. "Greetings Lord Lucifer"
Sirzechs Lucifer raised both hands, "No please, no need for such formalities"
Lord Agares straightened his posture slightly more relaxed, "Please to see you my Lord, If you would have notified us beforehand of your visit we would have prepared more-"
"There is absolutely no need for it, I didn't notify you since it's only a semi-official visit, and I'm not staying for long."
Seekvaira arched an eyebrow with subtle curiosity. "A semi-official visit, you say? Is it perhaps related to the latest council meeting?"
Sirzechs nodded with a warm smile. "Indeed, though I assure you, it's nothing too taxing. I simply wanted to speak with your family regarding some recent developments."
"If that's the case let's head to the guest wing", Valerius Agares looked toward his butler, Ravien. "Inform the kitchen to make some tea and bring it there"
"At once my lord" Ravien answered bowing his head before leaving the main hall.
The group headed toward the west wing, stopping in front of a medium-sized room. Inside, soft sofas were arranged neatly, with golden curtains hanging by the windows. A silver carpet covered the floor, muffling their footsteps as they walked in. It was an elegant living room clearly meant for private talks and informal meetings.
Adrien was, surprisingly, silent the whole way. When they entered the room he didn't sit on a sofa like the rest, he just leaned on a wall and said, "What an amazing entrance Sirzechs, had the maids on the floor" he said mockingly.
Sirzechs wasn't offended at all, that was the way Adrien talked with everyone, he just chuckled amused, "did you help her up?"
"I may be slightly eccentric but I am gentleman" He answered matter-of-factly.
"Slightly?" This time, it was Seekvaira who replied, causing both Serzechs and Valerius chuckled.
"Well, I thought that if I don't make an entrance, you wouldn't even show up".
"Me? Hell no—I'm not stupid. When the Demon King calls, you show up" Adrien said, acting offended.
"Is that why the last time I came you said you couldn't be bothered?" Serzechs answered still smiling softly.
'Shit, is he angry? I don't want to anger him, he's wayyy to influential'
"Ahaha, well... I really was working hard on a project and I couldn't come so I..." Adrien sent help signals to Seekvaira but she ignored him completely, adjusting her glasses.
"Well, please forgive my son for his unbecoming rudeness", his father answered shooting his son death glares, apparently he wasn't present that time.
'Whewww, saved me'
"So what do we owe the pleasure of your visit?" Valerius Agares changed the discussion before Adrien could humiliate him even more.
Sirzechs let the matter drop, he smiled and said, "Well, first-of-all, I would like you to inform the great king faction that the red dragon emperor has appeared and has possessed a human boy named Issei Hyoudou from Kuoh"
