I'm a Villain, So I'll Take Over The World!

A vast quantity of mana exuded around him in the form of cosmic air, swirling azure energy from his position as the magecraft forged something yet unseen before an intricate seal etched itself on the back of his closet.

The entirety of his home rumbled, quaking beneath the output of energy like anything else as the shine of esoteric magecraft gleamed against the walls of his room, shining through his window briefly.

"Ngh…"

For the first time, he felt his muscles ache from a departure of mana, having to exude an ocean's worth of magical energy to create what had yet to be seen.

After it finished, it looked as though nothing had changed, however, that was intentional to keep a level of secrecy to the true nature of the woven spell.

"Melly," he snapped his fingers.

The simple call caused the maid to return to his side as she looked at him with a kind smile as always.

"Yes, Master?"

"Follow me," he said with a smile.

He led the way, walking into his closet and stepping through the back wall itself as it had an intangible form that was unnoticeable unless knowing something laid behind it. As he stepped through the secretive entrance, he entered the premises of a vast mansion.

It was created perfectly to his will, using a certain billionaire's home as a basis. It was built like a pacific lodge, though taken to exuberant extremes, using douglas fir wood as the main material.

"Welcome to my new home: 'Xanadu 3.0'," he said.

"Amazing. Your abilities are simply beyond this world, Master Noah," Melly said, "This'll be quite the task for a maid such as myself to keep clean–I can already tell, this place is quite expansive."

'Ninety-thousand square feet, a library, gyms, endless rooms, food, and even a home theater. Though…this is the first time I've felt myself strained for mana after a spell. This was quite the task,' he thought.

The library itself was larger than his house, and the gym put any public gym to shame. He made sure to create it with his favorite foods stocked in the cabinets and fridge, keeping the entire place electrically powered with his own mana, though that part wasn't difficult.

It was undeniably a feat straddling the threshold of godhood.

"What would you like me to do, Master?" Melly asked.

He looked at her after being deep in thought, "Hm? Ah, you can do whatever you'd like for now."

"Really?"

"Even dutiful maids need days off," he smiled.

"Thank you, Master Noah," Melly bowed her head before heading off into the vast interior of the mansion.

It was disconnected from Earth itself, existing in its own pocket dimension that he linked directly to the closet in his room. Such was the perfect place to be able to use his magic without a second thought, and a sanctuary.

With that in mind, he didn't intend to leave it so vast yet unoccupied as he briefly left through the front door, leaving the subspace and walking the dark closet of his room again.

'It's time to finally start putting this power to some real use. If people out there want a fight, I'll make sure they rue the day they thought of challenging me,' he thought.

His sights were set on the figurines that cluttered his shelves. The bulk of the figures he owned were of characters from 'shonen' anime, usually super-powered heroes or villains, along with mecha builds that he'd spent far too much of his allowance on the past couple years.

Towing these inanimate objects back with him through the closet that led to the subspace mansion, he neatly lined the figures up in a large courtyard occupying the center of the spacious domain.

'Every king needs an army,' he thought.

Such thoughts were born not only from his cautiousness of the mysterious system wielders, but for grand plans of the future that he deep down yearned to enact.

A massive seal of purple majesty was born on the floor, spiraling as hieroglyphics spun and carried the inner workings of the intricate magecraft. Such immense magical energy caused an ungodly pressure to expand outwards, rumbling the entirety of the vast mansion as particles of mana flooded out.

Like a parade of colors, strands of crimson mana, azure bands, and flashing violet swirled around in the presence of the supreme magecraft.

"First things first, I need my own 'right-hand' men, so to speak…I need fighters capable of combating other system wielders," he mumbled to himself.

One-by-one, the figurines grew to the canonical size of their fictional origins, gaining the complexion of living creatures as blood ran through their veins, given life by the Creator's Grimoire.

The first to awaken was the figure pertaining to the main hero of one of Noah's favorite action manhwa: "Singular Leveling."

He had pitch-black hair and purple eyes that lightly possessed a shine, wearing a loose-collared, dark suit and wielding a massive greatsword that had a frosty-blue blade forged of mystical properties.
