"Miss Undyne, what are your thoughts on class 1-A?"

"They're sloppy, unrefined. But they have heart. With time and training, they will become great heroes."

"I agree with your assessment. I shall see you tomorrow for your own hero training."

"Okay, see ya tomorrow boss."

Undyne left the Principal's office and followed Sans's magical signature to the 1-A classroom. The scruffy human wasn't in the classroom and Sans was napping on the Bakugo kid's lap with a group of kids surrounding them. Her presence was noticed immediately by Sans's apparent friends. She wasn't completely sure why his new human looks changed so drastically since the Sports Festival, but he looked healthy enough and that was as she cared about.

Midoriya - "Hello Miss Undyne!"

Iida - "It is a pleasure to meet you!"

Uraraka - "Your hair is gorgeous!"

Her clear path toward Sans was blocked by three children.

The tallest of the three had his hand extend for a handshake, which she granted him. He had a firm grip, which she took as a sign of respect toward her. The smallest of the three, a girl with short brown hair and pink cheeks was trying to ask what hair products she uses, to which she tactfully ignored. The third, a boy with black hair with dark green highlights, caught her off guard.

Midoriya -"Miss Undyne, if you don't mind me asking, what is your Quirk? Also, are you an Underground Hero like Mr. Aizawa? If so, why did you come to UA?"

"The hell kid, slow down. No, I'm not an Underground Hero. I was a police officer before today. I came to this school because of your principal. My Quirk is Hydro-Forge. I can manipulate water around me, on me, or in the air to do what I want, but I really only use it to make weaponry.."

Score, her lizard love saved her fins once again with a prepared quirk explanation. She summoned one of her spears and handed it to the smaller boy.

"I use my Quirk to make these spears for combat, and I recently learned how to create a barrier with them."

Iida - "This spear is made from water? It's really dense."

"That's because of the water in the air. The oxygen, carbon dioxide, and natural nitrogen mixes with the water and makes my spears denser and harder to snap."

If she replaced the big science-y words with magic, she'd be telling the truth. She had no idea what those words meant, but she practiced her "Quirk" explanation for days before Alphys let her get the police job.

"Fascinating! Can you make -"

"Midoriya, please leave my super cool Auntie alone. I'll have a written explanation of her quirk written for you later."

"O-okay Gaster! It was nice talking with you ma'am!"

The three children scurried away allowing Undyne to seat herself near the front of the room. All the kids filed out grumbling about an "English class with Mic" so she was left alone with their teacher. All she needed was one look at him to gauge him and holy fishsticks. The man was deceptively strong. He hid his muscle and strength under layers of baggy clothing and an unkempt appearance. She could practically feel the power radiating off this human.

"Hey, mind if I check you?"

"What?"

I just want to check your stats, you can check me too. You don't have to if you don't want to."

"Sure, I don't care."

Aizawa closed his eyes to enjoy a sip of his caffeinated goodness. A strange box of text appeared in front of his closed eyes. Undyne focused her magic, feeling more strain checking people in this world than her own.

*You've entered a fight with Yamada-Aizawa Shota*

*You check, Yamada-Aizawa Shota*

*HP- 175* *Atk- 382* *Def- 297* *LV- 3*

*Yamada-Aizawa Shota check, Undyne The Undying*

*HP- 379* *Atk- 395* *Def- 286* *LV- 1*

*You SPARE Yamada-Aizawa Shota.*

"I'm sorry you had to kill people Aizawa."

"Wha -"

"LV. It stands for LOVE. The more people you kill, the high it goes, though I've yet to meet someone with an LV higher than one. So I'm sorry for what you've gone through."

"Thanks, I guess. It's an occupational hazard to being a hero. There are some criminals and villains who choose suicide by cop/hero in favor of going to prison."

"I can sort've understand that. My guardian, Gerson, was a Lieutenant in the Great Human Monster War. He told me stories about humans and turncoat monsters who would rather be killed in battle than be taken as a war prisoner. He never let me know what his LV was, but being in the war, I can only assume it was pretty high."

"He sounds like a good man."

"No? Gerson's a Turtle Monster. He's an old fart, but he beats me in every battle I start with him. He's awesome though, you got that right!"

Shota and Undyne told each other stories of their lives, politely listening to the other, until the kids all filed back into the room.

"Alright, sit down and shut up. Final Exams are happening soon. As I'm sure you've been talking to your upper years, you will not be fighting robots.

Sans sat in his seat, beyond confused. He shot a questioning glance at Katsuki and Eijirou. He'd been sleeping through most of his classes so that includes the walking in between. This was the first he was hearing of robots and final exams.

"Your final exams will contain two parts. A written test,"

Sans snickered at the childish groaning of his classmates and laid his head on his desk after a big yawn.

"and mock battles. The reason you are not fighting robots, is because you all have faced against real villains and have gained real life experience because of it. Robots would pose no challenge."

Alight, this was getting interesting. Sans could deduce that they wouldn't be fighting each other. That'd be too easy. So if they're not fighting each other and they're not fighting robots, that only leaves class 1-B and their teachers. Surely they wouldn't pitt a group of teenagers against full grown Pro-Heroes...right?

As Sans contemplated his existence, he was swept into his boyfriend's arms and swiftly deposited onto Eijirou's back.

"Sans! Wait up!"

Sans startled from his thoughts, now confused as to when he got outside. Undyne caught up to them and gave him and Eijirou a wolfish grin. Me, Al, and Mettaton have a place around here. She insisted on having you over for dinner."

"Al and Met. is here too?!"

"Hell yeah they are! You coming?"

"Yeah, we'll be there!"

"Great! Bring your boyfriend too. I'm sure Al would love to meet him."

Sans's face burned as she and Eijirou laughed at his expense.

"I'll make sure to bring Katsuki. We'll see you later Undyne. Have Al text me your address."

Sans jumped off of Eijirou's back and took a hasty shortcut home. Natsumi was chatting with Grillby over wine, Hitoshi took the day off school because he was sick so he was playing a video game with Asriel, and Ichika was preparing meat skewers for grilling.

'Eiji, take our stuff to our room please."

"No problem bro! Hi guys!"

Eijirou ran up to their shared room.

"Welcome home Sans, how was school?"

"It was very interesting Ma. You'll never believe who I ran into today."

Grillby smiled from behind his wine glass. Sans was literally one second away from telling them based on the overflowing excitement.

"It was Undyne!"

And Grillby's wine went up and out his nose.

"Easy there Grilbz. Ma, you can save the skewers for tomorrow. Undyne and Alphys invited us to their place for dinner."

"That sounds fun! What should we wear? Casual, formal, nude?"

"Lol, casual is fine Mom. I don't think they know about Azzy or Grillby so be prepared for similar reactions to Grillby's wine snort."

Grillby nervously chuckled while rubbing the bridge of his nose. Sans snickered and took a shortcut to his room. His phone was on his bed and it was going crazy.

SkeletonFreak: ☹︎□︎❖︎♏︎ ⍓︎□︎◆︎📪︎ ☝︎❒︎□︎◆︎■︎♎︎ ☪︎♏︎❒︎□︎

<~>

Sans all but threw his phone down in red faced embarrassment. He didn't know why he was reacting like this. It's barely a three word sentence, in a language Katsuki didn't understand, but still.It was a simple enough task to create the WingDings language with this world's technology, and he was on of four people in either world who could understand it, BUT HE STILL SAID IT THROUGH TEXT!

"Bro, you running a fever? Do you want Ma to reschedule the dinner?"

"N-nah, I'm fine Eiji!"

"Oooo~ Bakugo said something to you?"

Eiji smirked and waggled his eyebrows suggestively. Sans wanted to burst into laughter at how stupid he looked, but he could only manage nervous giggling and rubbing the back of his neck.

"Um, no...I actually said something to him."

"OOO! What was it!"

"Bro, your spending far too much time with Mina."

With a serious deadpan face, Eijirou cocked one hip to the side, put his hand on his other hip, tilted on eyebrow, and said, with the gayest accent Sans had ever heard,

"Spill the tea sis."

Sans couldn't contain the bellyaching laughter that escaped him. He was on his back on the floor with Eijirou right there with him. They finally got dressed after fifteen more minutes. Sans wore a dark red shirt with his pull over hoodie on top, a pair of black jeans, and his favorite bright pink sneakers. Eijirou wore a black muscle shirt with red words spelling out Crimson Riot (courtesy of Ichika), khaki cargo shorts,and socks with bright red crocs.

"Bro if Mina were here, she'd tear you apart for wearing crocs."

"What she doesn't know won't kill her."

Sans snickered as he led his brother to the living room. Grillby wore his usual suit without his apron, and his little spectacle glasses, Ichika wore a simple dark blue dress with tiny white flowers embroidered on the neckline, the bottom, and the cuffs of the sleeves, and a pair of small heeled pumps, Natsumi wore a bright yellow shirt with black polkadots, black jeans, and flats.

Asriel looked miserable. Hizashi was brushing the top of his head, sobbing about his baby going away for a few hours. Hitoshi and Shota sat on the couch, not at all fazed about Asriel's predicament. It was clear Grillby was the one who chose Asriel's clothes for the evening. A royal red long sleeved shirt, black shorts, knee high boots with the DeltaRune near the top, and Azzy's spear was holstered on his back. Grillby had yet to stop treating Asriel like royalty, and Sans was enjoying it every chance he got.

"Oh great Asriel, Prince of the Underground, what is your first decree?"

"M'lord, do you wish to have ice in your water?"

Eijirou and Sans teased him mercilessly with wide cheshire grins. Ichika clapped her hands, smiling at her two troublesome boys.

"Okay boys, enough teasing Azzy. Sans, the address?"

Sans took his phone from his hoodie pocket and sent Ichika and Natsumi screenshots of the address Alphys had texted him. It must've been child's play to hack his phone. They all piled into Ichika's car and with her lead foot, they were at the address in no time at all.

"I'll be right back. Gotta fetch Ground Zero."

Sans took a shortcut to Katsuki's house and waited patiently for the door to open after knocking.

"Hello...Gaster?"

"You can just call me Sans, Masaru. It's less formal and I am anything but formal. And yes it's me, something quirk related happened and this is how I look now."

"Understood. Katsuki is just putting some finishing touches on his cupcakes. You can come in and say hello to Mitsuki if you like."

"Okay!"

Sans walked into the house and was greet by the comedic cacophony of mother and son screaming at each other.

"DON'T FUCKING TOUCH THE CUPCAKES HAG!"

"I JUST WANT TO SAMPLE YOUR WORK YOU STUPID BRAT!"

"I'll take Katsuki if you take Mitsuki."

"Thank you for the backup."

Sans walked into the kitchen and saw Katsuki protecting two trays of beautifully frosted cupcakes. They were orangish with pure white frosting with little frosting made carrots on top.

"Ground Zero, those look amazing!"

Sans started damage control with Katsuki as he slipped Mitsuki a cupcake when the blonde child wasn't looking.

"You ready to go then G.Z?"

"Hmph. Yeah, I'm ready."

Sans quickly did a once over of his boyfriends wardrobe choice. Black skull tshirt, black jeans, black sneakers.

"Masaru, do you have a nice shirt Katsuki can wear?"

"WHAT?!"

"Yup, be right back."

"Richter, what the hell is wrong with my shirt?!"

"Do you, or do you not want to make a good impression on my Aunts and cousin?"

"Tsk."

Masaru returned with a nice light red and white plaid button down shirt. Katsuki quickly changed shirts and packed up his cupcakes in a sturdy container. Sans grabbed Katsuki's arm and took the shortcut back to Undyne's house. But something was...off in the Void. His body radiating the new a warm light in the inky nothingness, but he could feel something watching them. He quickly got to point b and they set foot on Undyne and Alphys's front lawn.

"Sans what was that?"

"I...I don't know. Nothing ever made itself know in the Void before. Something is categorically wrong. I'll deal with it later. For now, we have a dinner to go to."

This chapter has two dedications!! One is for nonbinary_individual and the other is for potatoreak. On the discord server I made for the book, @potatoreak uses the word "germanification" a lot and I love them for it. Undyne's quirk name, *Hydro-Forge* came from the big beautiful brain of @nonbinary_individual, so credit where credit is rightfully due. 

If anybody is interested in joining the discord server, pm me and I'll send you an invite! Til next time!
