"So what is it you brought us in here for, anyway?" Sue directed her inquiry at her brother. Along with her mother, they stood in the middle of the living room. The space was furnished with a couch, a television set, a coffee table, and two reclining chars with standing lamps.

"Take a look at this." Kazuma gestured to the far wall, bringing Sue's attention to a large rectangular object, covered in what appeared to a tarp.

"What is it?" said Sue.

"The Professor sent it to me yesterday via teleporter," Kazuma replied. "He says it was found in the ruins of the tower on the Island. Apparently it's a painting of two important figures in ancient mimiga history."

"That certainly sounds fascinating," said Momorin. "Do you think we could take a look at it?"

"Um... sure," Kazuma said hesitantly. "But, uh... be warned. You might be in for a shock." He steadily approached the object on the wall. With a single yank, he pulled off the tarp cover and tossed it aside, revealing the painted stone slab underneath.

Momorin let out an audible gasp, which Sue herself mirrored. She marveled at the sight of the familiar figure painted in detail on the slab. "Oh my god... is that Toriel?"

"Oh my..." said Momorin.

"That's correct," said Kazuma. "And the one next to her is Asgore, the King of Monsters."

"K-king? Then Toriel's the..." Sue cut herself off, barely able to contain her excitement at the revalation."Holy crap, do you know what this means? I'm friends with royalty!" she cheered. "You'd better watch out, Kazuma, or I'll have her take your head off!"

"Sue, this is serious!" Kazuma forcefully cut in. "Do you have any idea how significant this discovery is? If Toriel was a figure in ancient mimiga civilization, then that means the monsters that have suddenly appeared must have some connection to the Island!"

Sue suddenly hesitated, her excitement briefly giving pause. "Huh... I hadn't thought of that. Does this mean that Toriel really is a mimiga, though? I mean, she does look kind of like one..."

"Perhaps it is some form of phenotype variation," Momorin chimed in. "There were some mimigas on the island who were different. I believe one of them had purple fur, for example."

Sue shrugged. "I guess so. We'll have to ask her if we see her again."

"Ah-hah! There you are, Sue!" Sue's heart skipped a beat at the sudden shout, a loud female voice booming from the other room. She turned towards the door, and what she saw was both terrifying and bewildering. Standing at just over six feet tall was a large humanoid figure, clad in full plate armor save for her exposed head. Her skin was a deep blue hue, and gill-like protrusions extended from her neck, complimenting the appearance of her long red ponytail and single eyepatch.

With clanking footsteps, she entered the living room and stood several feet across from Sue. With a single gesture, a spear made of glowing blue energy materialized in her hand, and she pointed it threateningly at Sue's head.

"The name's Undyne!" she announced, her wide grin revealing a row of immense teeth. "We're going to be best friends!"

"Get away from her, you monster!" Momorin screamed. Moving with nearly blinding speed, she placed herself between Sue and Undyne, her arms outstretch by her sides in a protective pose. Kazuma said nothing, having retreated against the wall, his face frozen in terror.

Undyne's face contorted into a look of annoyance, and she held her spear upright by her side. "Hey, what gives? You got a problem with monsters?"

Momorin's face froze, nonplussed. After a moment's pause, she spoke again, her voice trembling in quiet anger. "You'll have to forgive me. I can't help but get a little bit nervous when strange fish people-"

"Water nymph," Undyne interrupted, plainly irritated. "I'm not a 'fish person', I'm a water nymph."

"I can't help but get a little bit nervous when strange water nymphs show up in my house and start brandishing magical weapons in front of my daughter, " Momorin continued. "Now you put that spear away before I put it someplace that will make you very uncomfortable!"

"Whoa! Calm down, lady!" Undyne exclaimed, her spear disappearing as she threw her hands into the air. "There's no need to... wait, did you say daughter?"

"Yup, she's my mom," Sue replied.

"So humans are already adopting monster children! That's great!" Undyne said. "Integration is going even more smoothly than I'd expected!"

"Huh?" said Sue. "No, that's not-"

"And look!" Kazuma flinched as Undyne pointed in his general direction, towards the tablet propped against the wall. "You even have a portrait of our royal family! You must really like us, huh?"

"Forget about that," Momorin firmly countered. "Why are you here? What gives you the right to trespass in our house?"

"Trespass?" Undyne hesitated, and panic slowly crept across her face as comprehension dawned on her. "Ack! You're right! I am trespassing! C-crap, I'm so sorry!"

"Don't worry, it's fine," Sue reassured.

"No it isn't!" Momorin yelled.

"H-hey now, calm down," said Undyne. "I'm pretty sure this is just a big misunderstanding. I didn't meant to scare you like that, honest! I just... well, I get a little overexcited sometimes. Frisk said he'd made a new friend, and I just wanted to meet her myself."

"H-uh?" Sue's eyes went wide in surprise. "You know Frisk?"

"Yup!" Undyne proudly responded. "We're besties! Though I guess if I'm best friends with you too, then it would be a tie? I wouldn't want to play favorites or anything."

Momorin paused, closing her eyes in contemplation. She stood in place silently, as though she didn't even notice the outside world.

Sue felt a pang of worry welling up within her. "Are you okay, mom?"

"I... I don't know," Momorin said. "For a moment, I was so frightened for you... but now I don't know what to make of this situation."

"Heh..." Undyne gave a single awkward laugh. "I'm sorry about that. I'm, uh... not really that great at first impressions."

"Undyne! There you are!"

Sue heard a familiar voice calling from the distance. She looked to the door and saw Frisk running into the living room.

As Frisk approached Undyne, he immediately grabbed onto her, hugging her tightly around the waist.

"Hey! Easy there, kiddo!" said Undyne.

"Undyne, you idiot!" Frisk cried out. "What were you thinking? You can't just go breaking into someone's house wearing battle armor!"

"Hey, relax," said Undyne. "Everything's fine now."

"And what if it wasn't?" said Frisk. "You know that humans are stronger than you. If Sue's mom thought you were a threat, and was willing to use to violence to defend her family... there's no telling how badly you could have been hurt!"

"Aww, come on," Undyne protested. "You don't give me enough credit! I totally beat you when we were sparring in the Underground!"

"That's because I didn't want to hurt you," Frisk pointed out, still holding on tightly. "You're my friend and I care about you. If I didn't, then I could have hurt you a lot more." He turned upwards and looked at Undyne with pleading eyes. "Just... promise me you won't do anything else reckless like this, okay? I don't want to lose you."

For a brief moment, Sue could hear Frisk whisper "not again" under his breath.

"Yeah... I guess this was kind of a dumb stunt, wasn't it?" said Undyne. She reached down and affectionately russled Frisk's hair. "Don't you worry about it. I won't put you through this again."

Frisk released his grip on Undyne, and the room fell silent ever so briefly, giving Sue a moment to process the events that had just occured before her. What did Frisk mean by "not again?" How did he end up knowing someone so... enthusiastic?

In fact, now that she thought about it, it was almost ridiculous that she was ever intimidated by Undyne. Her passion was infectious, and Sue couldn't help but admire her for it.

"Is everything alright?" Toriel's voice suddenly came from the other room. She soom entered the living room, with Sans following closely behind her.

Sans casually waved his hand to greet Undyne. "What's up, Kanye?"

"Everything's alright," said Undyne. "I think we managed to sort out any trouble... wait, what did you just call me?"

Sans shrugged. "Eh, nevermind. Glad nobody ended up getting hurt. By the way Momorin, I repaired your door on the way here."

Momorin blinked in confusion. "My door?" Undyne said nothing, her eye darting around uncomfortably.

"You can thank me later," said Sans. He then suddenly raised the top of his eye socket, as though he were raising an eyebrow. "Say, what's that thing there?"

Toriel turned her attention to the object Sans was referring to, and let out a startled gasp. "T-that tablet! Where did you get that?"

For the first time since Undyne arrived, Kazuma spoke up. "We were just about to discuss that, actually. Toriel... I think we need to talk."

It felt good to have a form like this again. That was Asriel's first thought as he peered through his new eyes, seeing the shape his body had taken. It was a familiar body, a large bipedal body clad in black robes, with a pair of massive horns protruding from his forehead.

He felt the broken soul in his body extend his arms - their arms - out in front of them, flexing their fingers as they both adjusted to their new shared experience. The second thought that crossed Asriel's mind was how powerful they were together. Asriel had but a single human soul bonded to him, and yet its strength was nearly the equivalent of seven; power as great as the one he felt when Frisk had last confronted him.

Frisk. That name. Asriel felt an intense resentment build up within him at the memory. At first, it had seemed like Frisk was a friend. Saving him from the depths of his own madness, showing him the error of his ways. It was because of Frisk's kindness that he had decided to shatter the Barrier, going back to his soulless existence so that everyone else could be happy.

But Frisk wouldn't let them be happy. He reset to before their battle began, and made it repeat all over again. Over and over, Asriel would attempt to smite Frisk with his godlike strength. And over and over, Frisk would put on an act of kindness and persuade him to let go, sacrificing his own happiness for everyone else's.

Asriel fell for it every single time. Even when it became clear that Frisk was resetting to mock his incompetence. All the power in the world, and he couldn't even destroy a single human. All because he was foolish enough to keep letting Frisk win.

"You are wondering where our power comes from."

Asriel was startled by the sound of the broken soul speaking through his mouth - their mouth- reverberating fiendishly just as when they first met.

"That anger you feel. That hatred. That is what makes us strong. Embrace the power of hate, and together we shall become a god."

Embrace hatred... Asriel liked the sound of that. Yes. That would be the solution. The God of Hyperdeath would rise again.

"God of Hyperdeath. What a pathetic name. No... that will not do."

What? Pathetic? Yeah, right. He would like to see the broken soul come up with a better name.

"Actually... that is not a bad idea. My old name no longer holds any meaning to me. Perhaps it is time that I granted myself a new one."

Asriel's curiosity was piqued. Now he really would like to see the broken soul come up with a better name.

"You can call me... Samael."
