(A/N: Since I'm currently obsessed with Zamasu at the moment and Stacked Waters mentioned how it would be interesting to see a yandere Zamasu, I decide to write this little piece. :D You might want to read my Human's Are Idiots story so this will make better sense, but of course you don't have to. ^^

Not certain how many parts there will be, but I'm planning to make them very dark. I'll put the warnings in the chapters in case you aren't comfortable with certain situations. Also if any of you want this to be a Zamasu/Oc/Goku Black story, let me know. ^_^)

A young girl stood in complete awe at the scene before her. It wasn't like this was her first time seeing incredibly powerful and dangerous aliens engaged in combat. She had watched the battle with Cell on TV when she had been a very small child and had even seen innocent people get turned into candy of all things by a pink skinned creature she had learned was called Buu, (barely avoiding the same fate herself), but she had never been so close to witness the impressive sight up close and personal.

Her cousin, Leo, was an employee at Capsule Corporation. And while he had technically been advised to keep the fact that Bulma Briefs, who came from one of the wealthiest families in the world and happened to be married to an alien called a Saiyan-someone who was capable of destroying the earth if he so wanted to-a secret, he had unfortunately been unable to do so from Takara.

The girl had always been too inquisitive for her own good, and Leo feared it would lead to the both of them ending up as training dummies for Vegeta-something Bulma had threatened to do to Leo if he ever thought of blackmailing her or her friends with the information he had on them.

Surprisingly Bulma hadn't gotten angry with Leo like he believed she would much to his immense relief. The blue haired woman had found Takara amusing, informing the teenager she could come visit her cousin any time she wanted. In return, all she had to do was look after Trunks and Goten whenever Bulma required her to, which was definitely no easy task.

While it had taken some time to earn a lot of the members trust, Takara had eventually been accepted by the odd group of friends. That was how she was currently viewing Goku and Trunks, (whom Takara was still having difficulty coming to terms with the fact was the future version of the cute, yet mischievous child she looked after), battle it out high above the ground. Their power ups had even been so intense that it had caused the entire sky to turn grey and stormy along with the wind to harshly pick up.

"I still can't believe people this strong exist!" Takara squealed out, bouncing on her feet in excitement despite the fact that Trunks had been sent crashing to the ground. He was only a little bruised, so she didn't rush to his side like Bulma and the others had.

"Yes…I'm sure the people that had to endure that powerful wind storm just now weren't enjoying the abrupt change in the weather as much as you, though…" Leo mentioned with a tired smile.

Takara just laughed lightly, blinking in confusion when the sky that had brightened once the fight had concluded, was darkening yet again. This time lightning was crackling from it, giving the atmosphere a more ominous tone.

"I'm guessing this isn't something normal…?" Takara mentioned softly since the others even appeared startled.

"No. It isn't…" Piccolo muttered with narrowed eyes, having just arrived with Krillin.

A crack in the sky appeared where a figure emerged from it. The man garbed in black clothing looked like an exact replica of Goku, yet his appearance and demeanor was clearly darker and colder compared to the normally cheerful Saiyan's.

"Huh? What is this place?" the man mumbled, raising a thick brow when Future Trunks called out his name. "Trunks, in a place like this?" When his attention landed on Goku, a smirk formed on his features. "So, you're Son Goku?"

"And you're Black?!" Goku shot back, his expression serious.

Black's smirk seemed to grow, his wandering onyx eyes landing on both Vegeta and Lord Beerus. The shocking moment was when his gaze moved on Takara, causing the raven haired girl to tilt her head since he appeared startled at first; his face then taking on a manner of amusement.

That looks like the girl he told me about. Well isn't this interesting Black thought, chuckling to himself.

"Bastard! How did you come here?!" Trunks angrily demanded, snapping the Goku look alike out of his thoughts.

"Apparently, I came through the same path in space-time that you went through," Black replied. "Perhaps you called me here…to die by my hands?"

Leo bit his lip, taking hold of Takara's hand since he hadn't liked the way this 'Goku Black' had been staring at his cousin. "I think we should leave here right now…"

Not even getting to take two steps, Black had shot a Ki blast down at the ground near the two humans, causing Takara and Leo to freeze in place.

"I'm afraid I can't let you leave. You should stay and enjoy the show of your 'friends' dying slow and painful deaths at my hands," Black mused with a dark grin.

Goku who had flown up into the sky, merely smiled at his copy and moved into a fighting stance. "Sorry, but there's no way that'll happen. Even if I hear you're pretty strong,"

"It's an honor. I also wanted to fight you in this body," Black admitted, his demeanor showing one of absolute confidence.

"Huh? What does that mean?"

"There's no need for you to understand that." Black claimed, forming a yellow and black ball of energy in his palm and firing it straight at Goku; the impact sending him sailing far off and toward a rocky landscape.

Takara blinked as she watched Vegeta, Future Trunks, Krillin, and Piccolo fly off to be closer to the battle scene, turning to Leo who looked paler than normal as she tugged on the sleeve of his lab coat to get his attention. "Do you think we should try and leave still…?"

"I would advise against that. Unless you want to be blasted by this dangerous Black character," Whis voiced, his words causing Takara to frown and Leo to grip tightly onto her hand.

Bulma who looked nervous, managed to crack a smile as she looked over at the two. "D-don't worry. Goku and Vegeta will be able to stop that creep!"

Leo just chewed on the inside of his lip, not too certain about that. Noticing the crack Black had come through was shooting out a dangerous energy, he couldn't help but get a bad vibe, as if something terrible was about to occur.

Goku and Black's battle had grown more intense, yet it didn't appear as if they would be able to finish it. The distortion was trying to draw Black back into the future, causing the male to grit his teeth in frustration.

If I'm being forced to return, I'll bring back a consolation prize with me Black decided, struggling against the pull.

Realizing he was heading for them, Leo stood protectively in front of Takara, only to scream out in pain when he was backhanded into the nearby gazebo.

"L-LEO?!" Takara cried out in concern since his body impacting with one of the pillars had been knocked unconscious, her green eyes widening in fright when Black wrapped an arm roughly around her waist. "Wh-what are you doing?!"

"Be quiet." Black instructed coldly, extending out his hand and destroying Future Trunks time machine; an icy smile on his lips as he stared at the horrified expressions he was receiving before his prisoner and himself were pulled into the portal; the distortion instantly closing before anyone could pursue after them.

Takara had shut her eyes when they had gone through the portal, but she slowly peeked one open, only to have both of her green orbs grow wide at her surroundings. Future Trunks hadn't been kidding when he explained about his time period. It looked like something out of a apocalyptic horror movie. The area was dull, decrepit, and gloomy, and not a living soul could be seen anywhere.

"…This is horrible." Takara whispered out, feeling her chest tightening in sadness.

"Horrible, you say?" Black chuckled out with a smirk. "Is it horrible to cleanse the world of the filth that inhabit it?"

Takara gulped since this guy was clearly out of his mind, and even knowing she'd most likely die, she was tempted to bite his arm in the hope that he would release her. However when she noticed Black gritting his teeth and holding onto his chest as if in pain, she couldn't help but feel a bit concerned for him despite the fact that he had injured Leo.

"Erm, are you alright…?"

Black didn't answer, instead plummeting toward the ground as this caused Takara to scream; the fear causing her to pass out as she thankfully didn't feel the force when he crashed. Not that she would have been injured for Black had shockingly held her where she ended up on top of him.

"Honestly. I don't see why he was so fascinated with this creature…" Black scoffed out, wincing in slight pain as he slowly sat up after having roughly pushed the unconscious woman off of him.

If there was one good thing that had come out of this, it was that his encounter with Super Saiyan Goku would no doubt increase his own power, something that left Black feeling extremely gleeful. What was even better, he had destroyed Trunks only means of returning to this era. There was no one who could stop him and his partner from finishing the annihilation of the human race.

"The only question is, what should we do with you?" Black pondered, lifting the glasses wearing female up by the back of her turquoise shirt and lightly swinging her from side to side.

In a rather large cabin in the mountains, Zamasu sat at a rounded table sipping on a cup of tea. Yet sensing a familiar figure approaching, he turned his attention on him; a white brow lifting up when realizing he wasn't alone.

"What have you got there?"

"A present," Goku Black answered with a smile, dropping the girl carelessly on the floor.

"I wouldn't call a mortal something as nice as that," Zamasu chuckled out, standing up to examine the young woman. His grey eyes widened once he examined her features better, but there was no possible way this could be who he believed it to be.

"You probably sensed my disappearance earlier. Seems Trunks had a time machine to travel into the past. I was able to follow him there briefly, and found this creature there," Black spoke up, folding his arms over his chest. "She's the one you talked about, I assume?"

Zamasu didn't say anything, moving some of the hair that had come loose from her ponytail off of her face almost tenderly. Takara's body lightly twitched from the contact, and she let out a small moan, her eyes slowly fluttering open as even with her glasses, it still took a moment for her vision to adjust.

"H-huh?" she voiced tiredly, her eyes spotting a pale green skinned male kneeling down in front of her along with Black leaning against the balcony's railing with a bored expression.

A terrified squeal left her light pink lips, and Takara scrambled away from the white haired and green skinned male; shakily standing up on her feet and trying to flee. Except, she had ended up running straight into the glass screen doors.

"There's something very wrong with this woman…" Black muttered out, a small sweat drop rolling down the side of his head seeing Takara now sporting dizzy eyes. It was amazing she hadn't broken her glasses with that painful sounding collision. Or had knocked herself out for that matter.

Zamasu had a bead of sweat trailing down his own head, but he found his lips twitching from enjoyment at the girl's clumsy nature. She was just as foolish as he remembered her being.

"Calm yourself before you damage your brain cells any further," Zamasu commanded, placing his hands on the teenager's trembling shoulders since she looked like she was going to have another panic attack.

It took Takara a moment to realize she had been insulted, her cheeks puffing up in annoyance. "Y-you can't talk to me like that! You…um…who are you exactly?" Takara trailed off with a sheepish smile.

"Zamasu. And I gather your name is Takara, correct?"

"Yes…" Takara answered back quietly, her head cocking a little to the side. The way he had said that, he was acting as if he knew her, but also seemed like he wanted to confirm his statement too.

The raven haired girl felt even more bewildered when Zamasu looked pleased, and she placed her hands on her chest while glancing around nervously. "I'm not really sure what's going on, but can I go home…?"

"No," Zamasu said in such a sharp tone, it caused Takara to back away slightly from him. Seeming to understand that he had frightened her, Zamasu said in a much calmer tone, "You cannot return."

"The time distortion sealed itself. I'm no longer able to travel to your world, nor can Trunks or the others come here," Black spoke up nonchalantly.

At these words, Takara's body lightly shook while her skin grew paler. "A-are you saying I'm stuck here…? No! I-I have to get back to Leo…!"

Even if he knew Leo was related to her, Zamasu couldn't help but feel strangely angered hearing how she wanted to be with this man and not him. He had lost this creature who had fascinated him so once before, and he would not lose her again.

"You can not. This place is now your home," Zamasu informed. Seeing Takara shaking her head in obvious disbelief while tears formed in her eyes, Zamasu surprised both Black and the girl when he used a finger to wipe away the tears that trailed down her cheek. "Come. I'll take you somewhere you can rest and calm your nerves."

Black wasn't sure what to think when he watched the human hesitantly follow after Zamasu with her head lowered. His future self showed the same disapproval as he did toward mortals, yet he oddly seemed to care about this girl. He knew Zamasu said the human had merely amused him when he was assigned to watch over the earthlings by Gowasu, but he hadn't expected this at all.

"I suppose it will be entertaining to see why this human has managed to enamor him in such a way," Black mused with a small smile and shake of his head. "In the end, she'll still no doubt meet the fate as the rest of the filth once he grows tired of her."
