In the grand tomb of Nazzereck, Albedo stood next to the throne of Ains Oon Gown. Her eyes were deeply fixated on the orb, so much so that she didn't notice that Demi-urge had entered.

He too saw what she was deeply fixated on, a fight between a human child and the true vampire herself. The sight almost made the demon himself lose his composure in a bout of laughter. "Such a mismatch, it's almost a joke."

The succubus only gave him a glance with no emotion behind it. "Yes, quite." Since the orb was focused on Shalltear's location it meant that Aura's protection from detection was also null and void. "They will all learn to not dare to defy, my lord Ains~" She shuddered at the mention of her lord.

Demi-urge pushed up his glasses in mutual agreement. "Well, lesson learnt for them. Such a shame that Aura is now one of them." He lamented only a little as he looked more closely into the orb. "So that's Frisk then? I have no idea why our lord was so fascinated with a human so feeble looking as this."

Albedo nodded before she realized something about the human. "Why are their eyes closed? Are they actually blind, how pitiful."

Demi-urge was curious as well why a human would be stupid enough to face a vampire with such a disability. However, when he looked closer he notice how the child's eyelids were incredibly tense. "They're doing it on purpose, Wait." He surprisingly got a chill on his unholy spine when the child smiled and cackled with an insane glee. "Wait, are they the ones responsible for the laughter?"

Albedo laughed, assuming that the demon was joking. "No way could a weak human be able to do that!"

Demi-urge removed his glasses as the fight was about to commence. His diamond eyes shine as they scanned every detail that was about to happen. "Nothing is impossible Albedo, so we shall see." She snorted with disgust at his quote.

Shalltear approached the child slowey, a tactic to inspire fear to those far weaker then hèr. "I'm going to take my sweet time with you, the flower, and the bastard of an elf." She promised as she wiggled her fingers.

The double whistled at the vampire. "Yeah...by the way nice stats, seems I was right to wait." The true vampire stopped at the claim in confusion. "Least I know my check still works, though credit might take awhile..."

She frowned at being ignored by such an ingrateful maggot. "Hey take this fight seriously! Death would be such a blessing for you when I'm through!" Her frown deepened when the child only smiled. "And what is 'check' anyway? A worthless skill?"

The double feign surprise and fear. "Ohh nooo, my trick has been found out. Hahahaha as if it's worthless! However, an ignorant knucklehead like you can never understood it's properties." The vampire was about to strike from the insult when the child continued. "Shalltear the bloodfallen, 88 attack, 85 defense...lalalalala~" They started to sing as the Vampire actually grew a little worried. "Not as much like Undyne the undying or the royals, but you might be worth some excitement." They gave a shrewd smile and revealed their eyes for a split second to the vampire. "Be granted the pleasure of pain!"

Suddenly a wave of intense and fatal madness filled the air, even causing Zaryusu to vomit. "W-What is this feeling, it's like my mind is made of water..." Zaryusu groaned in pain as he lost the abilty to move or comprehend his surroundings. Even the vampire felt the immense amout of ungodly maddes that resided inside the double.

Strangely Aura was uneffected by the madness and blinked in confusion. "What's wrong, why did you vomit? They haven't even fought yet?" She inquired as she slowey recovered from the fatigue.

The double cackled as the lizardman and vampire heard an eldritch-like laugh, while the elf heard only their usual laughter. "Now, let me tell you my stats. It seems my defense and attack equipment also counts for magical defense and attack, lucky. Attack and defense are over the limit, I guess this world can't limit my weapon or armor effects to my personal stats." Shalltear took a step back, she wasn't even sure this child was sane or bluffing. "Agility's the same, resistance is 89, and the special ability is an unknown stat." Shalltear grit her teeth as they know that this human must be bluffing.

"Like hell it is you maggot!" She dashed forward so fast that the lizardman couldn't even see her. Even Aura could barly keep track of the speed and closed her eyes for the worst to happen. "Die!"

In a blink of an eye the double dodged the insanly fast attack with no effort. "Dye...no my hair is all natural my dear bitch, unlike your chest." They joked as they stuck out their tounge at the vampire. "There's no loot inside of it!"

She fumed at the jabbed at their secret. "You think this is a joke, then try if you can make a joke about this! Summon household!" A heavy swarm of bats and wolves leaped out of the darkness in the forest. "Attack that worthless piece of existance!"

As they attacked all at once the child smiled. "Challenge accepted, I'm glad you have friends of the same size!" They vanished before several dozen red lines had decimated her entire reinforcements. "But it's not nice to pelt them at a child, dirty horse!"

Aura weakly raised her hand in the air. "Nice one!"

The double turned back and gave a thumbs up. "Thanks." They turned back to the vampire and pointed them with the true knife. "Now then, let me show you all a magic tri-"

"Implosion!" The true vampire used one of her most powerful and last resort spells against air controted around the double. They responded with a knowing smile before a powerful blast occur. A rain of black liquid started to rain down upon the battlefield. "Ha, no human can defeat me!" The explosion had made a huge and dense smoke cloud. It was hard to tell how many pieces were blown apart inside the cloud.

Aura felt tears well up in her eyes. "No..."

In the tomb, Albedo stood up and began to walk to the exit. "The deed is done, though it did surprise me that they actually had a chance." She gave a hollow laugh at the result. "Then again, no human maggot could possibly defeat a floor master alone."

Demi-urge was quiet still scanning every detail. Then his dimond clear eyes spots movement inside the implosion's smoke cloud. "Wait what, they still live!?" He was shocked that anything could live from implosion.

Albedo dashed back to the orb and saw the moving form as well. "Maybe some pieces remained from the implosion!?" But then the human exited the smoke cloud completely unharmed. "What the fuck!?"

Shalltear face grew paler then it once was as the human left the cloud in perfect condition. "H-how!?"

The double smiled as they showed off some foggy glasses and a self-inflicted knife wound on their right hand. "These cloudy glasses are an excellent style of defense, by taking damage the wearer gains immunity from all attacks for three whole human seconds! Get these lovely glasses now at a Gerson's shop near you. Warning this product does prevent karma or stupidity." They smiled after their small showmanship bout of insanity. "In other words you only damaged the land around me by contorting the air, also that was very rude of you!"

The three monsters all had thier jaws drop from the quick exploit. "Wow..." Was all that Aura could say, Zaryusu was still paralyzed by the madness.

Shalltear took a step back in fear, at which point she knew she lost to a degenerate human. "Y-you can't be human, no one has survived implosion before!"

They shrugged to her shock. "Oh no you definitly would have killed me had your spell not have been so verbal. It's like this is an anime akin to DragonBall Z or Bloodlad, I personally loved that anime." They smiled fondly at their distrubing memories before pointing a knife at Shalltear. "Well I guess your time is up, flathead. I did promise that I would teach you to fear death."

The moment she tried to run, the double was again in front of her. "Telepor-!?" The double gripped her mouth silencing the true vampire. She bit them, thinking they were stupid to try that tatic. Then she felt an intense pain in her mouth, like she drank a vat of boiling acid.

The double laughed as she struggled. "Yeah, my blood is a little sour with the flavor of madness, but what can you do?" They laughed as they tighten the grip on her jawline. "Now, I grant you the mer-"

"Frisk! Don't kill her!" Aura shouted, completly recover from magic fatigue. "It's not right, let her live!"

"Oh great another monster with the morals of-you know I'm tired of being referenced as my accursed other half!" They shouted more angry with their name then the issue of the vampire's death. "This is who I wa-no who I am, but I was locked away by a naive fantasy where death dosn't need to happen!" They kneed Shalltear in the gut which caused her to cough up and accedently suck more of the acidic blood.

"I know she wanted to kill everyone and I know you want to return that feeling." Aura walked closer to them until she was face to face with the double, unaffected by their madness. "That death will always happen to even those who don't deserve it."

"Skip the goody two-shoes speech and get to the point."

She sighed and put on a determined face. "I won't stop you, but don't delve into her level." They were in complete dead silence before the double gave a small, but a diabolicaly mad smile. Aura closed her eyes expecting a slash, snap, or a bloodcurdiling scream.

"Hehehe, fine but let's leave her a parting gift." They stared into the tortured eyes of Shalltear. "Face madness of my soul!" The double was in kissing range with the vampire. The double opened their eyes and Shalltear screamed as she saw the pure and unadulterated insanity inside the double. Then she fell limp and motionless from the mind attack. "The eyes are the gateways to the soul, mine's like a eldritch's hell gate~" The double sang in madness.

Aura looked down at the limp Shalltear. "Thanks for not killing her." She gave the double a hug. "See, you're not so different from Fr-"

"I just said don't refer or compare me to my weak double!" They growled before brandishing the knife away. "But, I'm going to take a nap...So..." They fell over backwards and then the aura of madness vanishes Like it never existed.

There was complete and utter silence in the tomb of Nazzereck. Demi-urge hastily put on his glasses before Albedo would snap in a rage.

Behind the throne room Demi-urge collected his thoughts on the battle. "It's harder to predict a genius then a fool, but the insane are always out of the equation..." He sighed and reveiwed the evidence in his mind. "They cracked Entoma, but Shalltear means that they could possibly break anyone's sanity. They are also almost physically impossible to catch, intelligent or lucky enough to dodge implosion, and Could wipe out a maid of Nazzereck with possibly one hit."

As the situation with the human grows more dangerous, the more Demi-urge realized that they need to be more quiet and catious with their ops.

"Ains needs to know, but not now in case the sudden awareness could break his cover." Demi-urge made a mental note to warn Ains as soon as he comes back to his grand tomb.

Hey everyone, every chapter seems to grow more and more short. I could make the case that this is a fight chapter, but honestly it was hard for me to do Frisk's double because of how insane and unpredictable they should act. I really don't know how to write characters with those attributes.

Also before I get bombarded by correction comments, stop and listen to me please. I actually looked at both fandom wikis and was actually surprised that the true knife (It's real knife, but my version sonds cool) and the heart locket provides 99 attack and a defense stat boost. I also did the magical stat addition since all the weapons and armor in undertale appears to be made of magic and should boost those stats as well, easy example is the empty gun, temmie armor, heart locket, etc.

I hope I respected both fandoms by making Frisk's double the first, actual, and (maybe?)the only threat they have. I mean I watched Overlord's three seasons and the first and only thought that came to my mind was that the humans are fucked with no real contest. So I hope I respected both fandoms by making this decision, see you guys see you next time.
