"so, pal, about that pun earlier. it was good, but i think i can lend you a hand in improving them, whaddya say?" Sans held out his hand to Sirius, but when the other took it, the hand as well as the arm came clean off, making Sirius yelp. "hey, i said i'd give you a hand."

Toriel, sitting next to Sans, was trying hard to cover up her laughter, while Albus was doing his best not to groan, because although he'd done similar jokes in the past with props, it was still a horrible joke.

Sirius paused for a moment before bursting into laughter. The gag reminded him so much of what he and his friends used to do in the past, that he couldn't help himself.

"SANS! I CAN HEAR YOU MAKING HORRIBLE JOKES FROM UP HERE! YOU ARE DISTURBING FLOWEY AND I'S PUZZLE GAME!" A voice called from upstair, causing everyone's heads to turn in that direction.

"c'mon paps, it's been awhile since i've had an audience like this guy before! he likes puns almost as much as i do!" Sans responded. There was stomping as the person upstairs came closer, then a skull poked out from behind the wall, peering into the living room.

"OH! HELLO THERE! I DIDN'T KNOW WE HAD GUESTS! COME FLOWEY! LET'S GO GREET OUR NEW FRIENDS!" The skeleton said with a grin, grabbing the dark brown pot from off the ground.

Flowey, for his part, was silent. He didn't move, nor did he say anything, doing his best to pretend to be a normal flower. He'd played this prank on others in the past, and it NEVER got old.

"GREETINGS! I AM THE GREAT PAPYRUS! IT IS A PLEASURE TO MEET YOU! THOUGH, I BELIEVE WE'VE MET ALREADY!" Papyrus said, tilting his head at Albus.

"We have, I am Albus Dumbledore. This is Sirius Black, Harry's godfather." Albus responded, with a smile on his face. Sirius held out his hand, which Papyrus took after putting Flowey on the table.

"IT IS WONDERFUL TO MEET YOU! THIS IS FLOWEY! HE IS A VERY GOOD FRIEND OF MINE!" Papyrus introduced, gesturing to the still unmoving flower. Sirius had to keep himself from rolling his eyes. How old was this monster? 3? He seemed far too old to be making friends with inanimate objects.

But, Sirius, deciding to humor the skeleton, reached out to one of Flowey's leaves to 'shake' it, but was stopped when Flowey suddenly turned and gave him a huge smile.

"Howdy! I'm Flowey the Flower!" Said flower exclaimed, making Sirius jump back with a shout of surprise. Flowey doubled over with laughter, tears rolling down his face. "That never gets old! You idiot!"

"Flowey, don't be rude! It's not polite to scare our guests like that!" Toriel chastised, giving the flower a disapproving look. Sans, however, was chuckling.

"i'll, admit that was pretty clever you little weed." The shorter skeleton admitted, winking. Flowey had a smug look on his face.

"I… didn't know that plants could be monsters. I mean, the Whomping Willow might count but it can't talk! The closest thing to that would be mandrakes!" Sirius exclaimed, hand over his chest.

"Normally no, but Flowey is… special shall we say. Alphys created him by accident." Toriel explained.

Sirius was about to say something, when the front door unlocked, and in stepped four children.

"Mom! We're home! MK's parents sent over some cookies!" Frisk called, motioning to Chara, who had one hand in the bag of cookies, but took it out when everyone's eyes turned to him.

"Welcome home my children! I hope you had a nice time. We do have some guests so be on your best behavior." Toriel greeted, standing up and walking over to the four, pulling them into a tight hug.

The children hugged their mother back tightly, but Harry's eyes were focused on Sirius, who was staring back as well. When he was released from Toriel's embrace, the small halfling squirmed, moving closer to Frisk nervously.

"A-Are you my godfather?" He asked, his voice small. Sirius nodded. "I… kind of recognize you… somehow…"

"Yeah, I am… I don't know how you remember me, since the last time I saw you… you were just a little baby…" Sirius gulped slightly, his eyes becoming shiny. "Harry, I'm so, so sorry. I… that night, I was so angry that I did something reckless, which made me be locked up. If I hadn't done that, then you wouldn't have had to go to the Dursleys, I'm so sorry…"

Harry stared at the man desperately trying to hold back tears. He fidgeted a bit before Frisk pulled him along towards Sirius, stopping just in front of the couch.

"It's nice to meet you! I'm Frisk, I traveled with Harry all through the Underground! This is Chara and Asriel, our brothers." The ten year old smiled and held out their hand, which Sirius took gently.

"Nice to meet you. Um… I'm not really good with kids so… sorry…" Sirius mumbled back, rubbing the back of his head. Frisk elbowed Harry in the ribs, prompting him to hold his hand out as well. Sirius went wide eyed at the sight of Harry's skeletal hands, but took the tiny hand nonetheless.

"You were… telling the truth about Lily being a monster then… Merlin, how did I never notice?" Sirius mumbled aloud.

"Well, Lily said she had been hidden under a glamour, which wasn't all that uncommon. Many monsters hid under glamors during the war. Some of them managed to continue to do so afterwards it seems." Toriel explained, taking a sip of her tea.

"my bro and i have even been teaching the kid some monster magic, since he has the ability to." Sans added, making Harry grin.

"Wait, but how is monster magic different from the magic we use? You said that wizards descended from monsters, shouldn't the magic be the same?" Sirius asked. Toriel thought for a moment.

"Well, I suppose that has to do with the human DNA. Your magic is linked to your SOUL and if one has a mostly human SOUL, that magic is influenced by that." Toriel theorized. "It's a bit unclear, as it wasn't thoroughly studied before the war. Perhaps you can speak with our scientists about it, have them study it so it can be better understood."

"I would be more than happy to assist you. I truthfully wish to know as well." Albus said, a small smile on his face. "I'm sure that if we cooperate, we can make great strides in learning more about the connection between wizards and monsters. The Ministry would have to approve of course but I'm sure with some conversation we can reach an agreement."

"Well, my ex-husband is the king after all, diplomacy comes as second nature." Toriel replied.

"Mom… can we talk with Sirius a bit more?" Harry asked timidly, cutting into the grown up talk which was getting quite boring to him and the other children. Toriel glanced at Sirius, who gave a nervous smile.

"I suppose so, take Sans and Papyrus with you as well, you can show Sirius what they've been teaching you hmm?" Toriel suggested. She wanted the two skeletons to go to keep an eye on Sirius, but she was too polite to say it aloud.

"OK! C'mon, I can show you my 'Special Attack'! Sans and Papyrus taught it to me!" Harry cheerfully said, grabbing Sirius and pulling him to the backyard along with his siblings, Sans and Papyrus.

Sirius seemed confused by followed along, a bit curious. Once they got outside, Harry let go of his hand, and ran into the middle of the yard.

"This should be good, he's been practicing for months, Papyrus was eager to teach him. Sans helped out too a little… not much though." Chara said, sitting on a chair after brushing off some snow. Frisk sat down across from him, eagerly looking at Harry. Asriel sat on the ground, not that bothered by the cold seeing as he was very furry. Papyrus and Sans stood near Harry, who beckoned Sirius forward.

"HUMAN! I AM UNSURE IF YOU KNOW HOW TO BATTLE! DO YOU?" Papyrus asked, a slightly worried expression on his face. Sirius straightened his spine slightly, looking a bit proud.

"Of course! I've dueled a lot in the past but uh… are you sure it's safe to do it around a kid? I mean… Harry's not even 10 yet." Sirius trailed off, earning a scoff from Sans.

"don't worry buddy, as long as you don't have any actual intention to hurt him, you won't. go ahead babybones, rek this guy." As soon as Sans said that, the world went black and white, and Sirius' bright orange SOUL was pulled from his body, making him yelp in shock.

"WHAT IN THE BLOODY HELL IS THIS?!" He yelled, looking around, seeing Harry standing in front of him with a smile on his face.

"It's a battle silly! You dodge my attacks and then you either Fight or Spare me. It's kind of easy. But this isn't a real battle so don't worry. You get to go first!" Harry chirped happily, and Sirius saw several floating buttons in front of him.

He hesitantly pushed the 'ACT' button, then pressed 'Check'.

Harry Potter ATK: 3 DEF: 4 A half skeleton with a kind SOUL.

Harry smiled at Sirius. "OK! My turn now!" He yelled as two, large skulls appeared next to him, and without hesitation, fired blasts of white magic at Sirius.

Sirius, without a wand, could only dodge. He wasn't fast enough however as one of the beams grazed his side, taking off a small chunk of his health. It took a moment for Sirius to recover before he managed to figure out how to move his SOUL over to the MERCY button, Sparing his godson.

"OK, again, what the hell was that? That was not a battle!" Sirius yelled angrily.

"It was a monster battle numbnuts. That's how monsters fight. It's a turn based system. I mean, you could attack someone outside of their turn but it takes a lot of determination and training to do so. Determination and training that you don't have." Chara explained, picking at his nails.

He recalled the first time Harry had used a Gaster Blaster, freaking both him and Frisk out, bringing up memories of that run. But, after a while, they'd gotten used to it, encouraging Harry to practice with it.

"OK, and those… things he used!" Sirius asked again, gesturing to where the Blasters had been.

"gaster blasters. my dad created them… kind of. he just discovered how to use them. apparently every skeleton monster has the ability to create them, it just takes the right training to do so. i don't think any other kind of monster can use them though, since they're based on skeleton magic, which is slightly different than other monster magic." Sans explained with a casual tone, like it was the most obvious thing in the world.

"I… I don't even. Fine… this isn't the weirdest thing to happen to me." Sirius finally gave in, sighing. "But… it's clear that you guys are a good family to Harry… I won't try and take him away from you… on one condition." Sans gave the wizard a hard look.

"and what'd that be?"

"I get to visit every so often." Sirius said with a smile. Harry looked thrilled at the prospect, jumping in the air happily.

"It's a deal!" He yelled.

"hehe, kiddo you don't really get to make that call but… i'm sure tori will agree to it."

(Ok, so that's the last chapter for THIS part. I realized that if I have all the parts on this one story, it'd be like 100 chapters long and that intimidates me way too much. So I'm going to break it up a bit. This is the first part, then I'll do first year, second year, third year and on. It probably won't go on for as long as the actual HP series, since it'd take way too long to write. So, enjoy this chapter and be on the lookout for some oneshots of Harry's life with the Dreemurrs and the Skelefamily.)
