Demon Lord Diablo (How NOT To Summon Demon Lord)

Diablo had a item that was a marker that can change its form to any writing instrument, and that when he writes with it his name appears as the owner of the item (In Game), once someone sees the name they would thing Diablo always owner that thing but even if it was a person (Real Life).

Everything up to becoming adventures was the same just with the marker on him.

Diablo looked ahead as he saw three nearly identical girls at a series of desks. Each with short, somewhat messy brown hair tied with a ribbon, pale amber eyes, along with drooping canine ears atop their head and a matching bushy tail, each girl wearing a skimpy crop top with a baggy trousers, one wore blue, the other yellow, and the third red. What they also all had in common were immense orbs hanging from their chests, rivaling Shera's in size.

'Seeing them so much in the game is so different from seeing them in real life…' "So… Who do we speak to?" 'They look just like the quest-givers from the game. If I remember right, yellow, Jaune, is advanced quests, red, Rouge, is story quests, and blue, Bleu, is beginner quests.'

"The one in blue," Rem explained, pointing to Bleu.

'I'm so used to Advanced Quests I almost instinctively went to Jaune…'

"H – Hello…" Bleu greeted with a shaky voice as Diablo approached her desk.

Diablo did his best to put on a pleasant smile. "Hello. We would like to register."

"R – Right," she replied as she pulled a stack of several documents from under the desk.

Diablo twitched an eyebrow as he looked at them. 'Oh great… Paperwork…' As he scanned the papers.

"All done!" Shera cheered as she stood up straight, handing her papers and to Bleu. Turning to her Pantherian companion, she urged, "You're next, Rem."

Rem merely approached the counter without saying a word and began writing.

Diablo gave a smile as he patted Shera's head gently. "Good girl."

Shera looked up at him with astonishment before swooning as her ears wiggled.

"O – Oh…" she responded, seeming disappointed in his answer.

Diablo glanced past Shera to Rem, to see that she was done and it was his turn thy were out of ink and he remembered that he had that marker on him, after writing down everything he could think onto it he tried to give it to Bleu when she so it she was socked and asked, "Do you really want to give me something you own?" Diablo answered confused, "Is I need to so I can be an adventure." "Ok." Diablo was confused on what happened then he remembered that the marker was a item that you could display your named and that you own it, "So I own the paper i wrote my name on, does that mean I own anything I write my name on or is it only things that were a item in the game, maybe-,"

He was pulled from his thoughts by a light clunk as Bleu placed a large dagger on the counter. "Now, I need your blood seal," she explained, trying to hide her apprehension at the naturally imposing man before her.

"… Blood seal?" The same imposing man who suddenly felt like he was going to lose his lunch.

"It's necessary…" Bleu pleaded as Rem pricked the end of her finger and left a small, bloody thumbprint on her papers.

Shera quivered fearfully. "I don't wanna…"

"You have to," Rem urged.

Diablo, too fraught in his own fear to reassure Shera, gulped and tried to show as much false confidence as he could muster. "You'll never be an Adventurer if you balk at something as trivial as this. Besides, a syringe poke is hardly terrifying."

Rem blinked once or twice in thought before lowering one ear in confusion. "Syringe?"

"A needle used to draw blood."

She mouthed the word "oh" in recognition.

Diablo gulped down his nerves as he grabbed the dagger, trying to hide his trembling hand. 'It's just a little prick… like getting a shot…' With a single deft movement, he slashed the tip of his thumb.

All the girls around him shrieked in horror as blood shot from the cut like a hose.

Wanting to stem the tied swiftly, he slammed his finger down on the paper, unwittingly splashing it in blood, along with the terrified dog-eared girl behind the counter, who merely whimpered in fear.

Diablo twitched an eyebrow at his own mistake and weakly reach over and patted the girl on the head softly. "… Sorry…"

Bleu merely stood motionless, trembling.

After sorting out the documents, or what could be salvaged from them, sorting out the particulars, and cleaning up the mess, Bleu led the trio to a large mirror, the surface of which was black as night.

Shera looked at the object in thought, curious about its lack of reflection. "What's this?"

Rem answered plainly, "A mirror that gauges your power."

Diablo felt some sweat fall down his cheek. 'Oh this can't end well…'

Motioning to the mirror, Bleu explained, "Just put your hand on it and pump some mana into it."

Rem acted first as she put her hand on it. Almost immediately a partial reflection appeared in the mirror, though only of her, not of the surrounding area.

Bleu looked it over curiously, scanning over some papers she held at the same time. "Wow. It's so clear, and crisp. Looks like… Level Forty."

Diablo attempted to contain a small snicker, which earned him an annoyed ear twitch from Rem.

"Me next!" Shera cheered as she ran up to the mirror and placed her hand on it, watching her reflection form.

Bleu looked it over in thought. "Ooh, it's so clear. And goes all the way down to your chest. Let's see… if I can count the number of eyelashes and it extends down to your chest, that means… Level Thirty."

Shera backed away from the mirror in rejection. "… E – Eh…? No way…! I lost to Rem!?"

Diablo furrowed his brow in thought as well. "I think that mirror might be broken. She does have far more mana than her."

Bleu, wincing away from Diablo, argued weakly, "It measures a combination of mana, intelligence, skill, and strength."

"Oh. That is low intelligence, then."

Shera puffed her cheeks angrily.

Diablo merely stared at her adorable display before patting her head gently. "There, there. You have other things she doesn't."

That got Rem's tail twitching violently, though her face remained unchanging.

"What?"

Looking up from her papers, Bleu timidly urged, "N – Next…"

Diablo frowned as he walked toward the mirror incredulously, before looking at Bleu. "… I recommend you and your sisters close your eyes and mute your ears. Something tells me I might break this."

Taking his advice, Bleu backed away even further before Diablo put his hand on the mirror.

He watched curiously as he felt some of his strength leave him and saw the mirror change. Rather than show his reflection, however, it darkened even further, to a color of black that seemed impossible before it started sparking and sending energy bursting out in all directions, shaking the building violently. 'Ah fuck.'

Rouge and Jaune held each other as they shrieked in terror before Diablo finally removed his hand from the object, the energy receding completely.

The door on the side of the room suddenly burst open as a figure ran out in a panic. "What was that?!"

Diablo, still somewhat surprised by the development, turned to the source of the voice, a petite girl with short pink hair, teal eyes, an overly skimpy white outfit that hid very little of her delicate form, and two long, tall, black rabbit ears atop her head. Looking at her for a moment, he then pointed to the mirror. "It couldn't handle me touching it."

The girl just stared with befuddlement.
