"Bakugou! Bakugou!" Mina excitedly said, running up to Katsuki. "Izuku and the others are trending online!"

Katsuki was busy doing some cooking in the kitchen at Miruko's agency as he paused what he was doing to see the video, smirking at what he saw.

"Goddamn, Deku! Taking down the fucking Hero Killer?! Why weren't we in Hosu?"

"Hey rookies!"

The two turned to see a gleeful Miruko finishing a carrot.

"Warm uop and head out! We're going on join patrol!"

This made the two raise an eyebrow.

"Really? Ms. No Team needed?"

"This is a special occasion." Miruko assuered Katsuki as she took out her phone and put someone on speaker. "Sides, I got a feeling you know some of them."

"Hello, sweeties!" a familiar voice smiled.

"Midnight-sensei!" Mina beamed, waving at her Modern Arts teacher.

"What's bringing you around, teach?' Katsuki asked, geniuenlly interested.

"We've got a lead on something big." Miruko explained. "So big in fact, that Mount Lady and great Tatcian Tsuru will be joining us."

And at that, the kids' interests were peaked.

"…The old hag is there to keep peace between Sensei and giant fetish?" Katsuki guessed.

"Yeah, pretty much."

"Oh my, are you cold in this gym? I can warm you up after training if you wish~"

Lilique, Rikidou, and Kouji were all interning under Melony/Mother Snow , currently at her agencies training dojo. Thanks to her rather unique quirk; Snowball, a fusion of cushioning, damage absorbption and temperture control along with some snow creation, Mother Snow and those under her specialized in Rescue missions, which she was focusing on for the internship with the three students who had caught her eye.

And the kids had been doing quite well, Kouji asking the mice Melony allowed to live in the mountains where people were, Rikidou focusing himself to prevent the negative side of his quirk and Lilique acting as moral support to the two while also quickly finding and saving the civilains, all with a cute smile on her face.

Currently, they were working on endurance and strength, their mentor in her largest form. And they had been going strong, but where clearing beginning to tire.

"A-Aizawa sensei says disasters and nature don't care for us. So, we should endure." Rikidou said, Kouji noddimng and Lilique stopping to catch her breath.

"Just give me a moment, please…"

"…But…You're still students." Mother Snow reminded them with a gentle worry in her tone. She understood the Underground hero's reasons, but…call her soft, she still saw children in her interns. Children who were willing to take on a heavy burden, mind you…but such a burden, Snow felt, did not need to be placed so quickly on them.

With that, her mind was made up and she lifted a hand to pause the exercise

"Take a break. Sit with me."

The three kids were confused at first, but did as ordered, just as their mentor took them into an embrace. The cold immedatley began to vanish from their forms and happy, dazed smiles overtook their forms as they dozed off from the comfort.

The scene made Melony smile warmly as she began to dream of blonde and white haired children…

'…The moment Stain is dealt with?' She decided. 'I'll tell Toshi how I feel.'

But for now? She let her hardworking interns rest,

DEVIL

At the S-Rank Tower, Ochako was calling Izuku on her phone.

"I'm glad to hear you and Iida are okay, I just saw it on the news."

"Yeah, we were all watching each other's backs. Nothing bad happened other than a few scratches."

"Talking with Midoriya, huh?" Puri-Puri Prisoner said as she came over. "You two are really cute together, you know?"

Ochako turned bright red, and from the sounds of it, Izuku might also be having something of an embarrassed reaction.

"We're so pressuring him for details later," Sumiko smirked while having a coffee break with Atomic Samurai and Flashy Flash.

Tatsumaki smiled at the scene off to the side and made a vow: Next day off? She was remeeting her nephew….and also looking into hiring the Uraraka to construct her new place.

DEVIL

"Alright folks, we're doing joint work with the SCP Foundation's very own Vigorshy and his unit in Hosu to deter any future villain activity," Kaku said to the rest of CP9. "Boss Lucci is currently elsewhere so for the time being, I'm in charge."

Mukuro was looking at her phone. "I didn't think Midoriya and the others would do something so foolish."

"Don't overthink it, Ikusaba. I'm sure they did everything smart when confronting Stain. After all, they had their supervisors helping." Blueno said as he put a hand on her shoulder.

"Oy, come on! Let's show 'em what we can really do!" Nia called over.

DEVIL

"Wait until I tell Garp about this!"

Selkie, the seal like Rescue hero, beamed as he patted both Tsuyu and Mipha on the head.

"I knew you two were diamonds in the rough, but by Oda and Horkioshi did you blow my expectations out of water."

His sidekicks all clapped and cheered in approval of the two girls, who beamed at the praise.

A few hours ago, some pirates ead by the dreaded Innsmouth, had managed to lure Selkie away from his crew via a false distress signal, with the plan of using his ship to escape and holding his crew hostage…or selling them to the highest bidder.

But the two UA students were not deterred, even with the sidekicks managing to negotiate them being left alone. No, Tsuyu had easily dispatched of the lone female member and aside from Innsmouth himself, none of the priates lasted more than a single Fishman Karate move from Mipha.

Innsmouth himself, after tanking two punches and a judo throw, had tried to shame the two for betraying tyheir kimnd, reminding them of how unfair the world was to mutation types….

"Shut. Up." Mipha glared, silencing the pirate with a wave of Haki that made him wet his pants and knock his sibling out, while Tsuyu was unaffected and the crew stared at her in awe. "If you did this to feed your siblings alone, I'd understand. I'd even try and pull strings as a princess of our people. But you and your siblings are not innocent. You're all proud career criminals. Never mind the lust I saw in their eyes towards our mentors."

Tsuyu then slapped the Squid-man uncousious with her tongue.

"Oh come on. Mineta could've tanked that…Don't tell him I praised him, ribbit." She noted.

"About what?" Mipha smirked, smiling alongside Tsuyu.

All in all? It was a good day for the two water-based heroes in training.

DEVIL

"Midnight, we're en route as we speak! We'll be there in about five minutes!"

"Aw, you just take your time, girls! As long as you don't go and hurt those adorable faces of yours, then you can take all the time you need!"

Momo sighed. During a patrol with Tsuru, they received welcome aid from Metal Bat, Mount Lady, and Miruko along with their interns, which consisted of Kyouka, Minoru, Katsuki, and Mina. While catching up and discussing Izuku and the others' encounter with the Hero Killer in Hosu, a Villain Attack had been reported downtown.

Having summoned forth a skateboard through the lipids in her body, Momo rode it as fast as she could down the crowded street. The people were quick to jump out of their way when they saw her heading towards them, while all of the others were rushing for the hills in terror from what sort of chaos was transpiring at the end of the street.

"Oy, Ponytail! Glad you could come!" Katsuki barked as he saw Momo arriving. "You're not gonna fucking believe what this shit is!"

Momo looked to see what the others were facing off against and was deeply flummoxed by what she saw.

"Is that...a giant cake monster?"

Sure enough, it was a giant golem made out of cake, wreaking havoc on the town as people ran away in terror.

"Ruuuuun! It's Cakezilla!" Minoru panicked before being pelted and flattened under a mound of whipped cream.

"I've seen some pretty weird baddies on the news before, but this one takes the cake. Literally!" Metal Bat said.

"Ah, there you are! You showed up even faster than five minutes you know!" Midnight said, landing on her feet near Momo. "Are you okay? It wasn't too hard getting over here at all?"

Momo shook her head. "I'm fine, Midnight-Sensei, but we need to stop this monster now!"

"There's probably a Villain responsible for this," Tsuru deduced. "If we stop them, then it should stop the monster."

Then we should split up. Some of us will go find the Villain responsible, while the others keep the monster from rampaging any further," Metal Bat said, and soon, he, Tsuru, Katsuki, and Minoru went to track down Cakezilla's master, leaving, Momo, Midnight, Miruko, Mount Lady, Mina, and Kyouka to deal with the monster itself.

"ACID GUN!"Mina shouted, aiming both index fingers together like she was holding a handgun and firing a glob bullet of acid that hit Cakezilla, making it reel back.

Next, Momo created a giant hammer while Itsuka enlarged her fists and attacked one of its legs, making it stumble.

"Oh yeah!" Mount Lady shouted, grabbing Cakezilla and delivering a German Suplex, knocking it down for a moment and allowing Miruko to jump over and bring her powerful legs down on it.

"LUNA FALL!"

Midnight and Kyouka then took charge attacking it with their whip and earjacks respectively, breaking through layers of cream and frosting. Unfortunately, Cakezilla was much more resilient than it appeared and soon picked itself up, putting its body back together.

"Argh! This is pissing me off!" Miruko grumbled.

"It doesn't work, we're just wasting our energy!" Momo spoke up.

Midnight's eyebrows furrowed as her face reflected concern, trying to consider all the possibilities as Cakezilla let out a furious roar. She rubbed her chin in deep thought before her eyes lit up, everything clicking into her brain.

"I think I got an idea!"

"Mind sharing it with us? Rather now than later, old hag!" Mount Lady replied, her tone bound with a certain annoyance.

"If you'd give me time to get a word in edgeways, I might have time to explain!" Midnight retorted.

"We're listening, Midnight-Sensei!" Kyouka said.

"Well, since it's a monster made of cake, let's just eat it!"

All the other girls stopped in their tracks, flabbergasted by the idea the 18 Heroine had suggested. They exchanged glances that conveyed the uncertainty they felt, before looking back at Midnight.

"What?" Miruko flatly asked.

"Midnight-Sensei, are you sure?" Momo asked skeptically.

"Well, there's six of us. I think we can wolf it down in no time!" Midnight said.

"Free cake! I'm in!" Mina cheered.

"I hope you're hungry, everyone, we've got our work cut out for us!" Midnight smiled as she ran in.

"Ugh! That skank is crazy!" Mount Lady groaned. "I'm gonna regret this!"

"Eh, why not?" Miruko shrugged as she leaped in. "Hope you girls got room in your stomachs!"

Momo and Kyouka looked at each other, still unsure but ultimately, they followed as well.

The six proceeded to go on the offensive again, but this time, rather than attempting to blow it away like a sledgehammer, they went with the scalpel method, tearing away small bits of its outer layer as they proceeded to chow down on the first mouthful of many more to come.

"Mmmmmm~! This is delicious!" Mina moaned, her mouth stuffed with whipped cream. "I think I can eat this all day!"

"I sure hope this actually works," Kyouka said, though she'd be lying if she said wasn't enjoying the cake.

"At the very least, this cake is quite delectable," Momo admitted.

"Less talking, more chowing!" Miruko urged.

"At least I'll be giving my fans something to remember..." Mount Lady sighed.

Mouthful after mouthful, they forced huge portions of cake into their mouths, making Cakezilla shrink down. Whatever the strange mixture of this monster was laced with, it had already begun taking quite its toll on the six ladies' bodies.

Without them noticing it, their slim, muscular bodies began to disappear relatively quickly under layers of soft, tender, flabby fat. In a very short amount of time, the six sumptuous ladies went from thin, with some muscle definition and generous, envious curves at all the right places; to quite fat.

"Ugh. S-So full-*BWOOOOORP!*" Momo moaned before involuntarily letting out an unladylike belch, making her face turn red as her costume in embarrassment.

"Oh man...they'll have to roll me home now..." Kyouka groaned, looking over her now rotund and rubenesque body.

"Hehehehe, I'm like a big pink marshmallow now~" Mina giggled as she played with her newfound fat.

"It's gonna take forever to work this off..." Mount Lady whined as she shrunk down and felt her fat body all over.

"Awww come on, don't feel bad!" Miruko laughed, slapping her belly. "To be round is to be proud, ladies!"

"That's right," Midnight said as she held the now-helpless and shrunken cake golem in her pudgy hand. "At least this thing won't be causing havoc anytime soon."

The 18 Heroine then proceeded to shove Cakezilla into her mouth, gobbling it up in one bite. Her distended stomach rumbled as she rubbed it.

"*BWWWWUUUUUUUUUUUUUUAAAAAAAAOOOOOOOORRRRRRRRRRRRRPPPPPPP!*Damn, that felt good." Midnight chuckled, a grin forming on her chubby but still gorgeous face.

"Well, it seems my daughter has been having fun making an absolute pig of herself."

Midnight paled as she turned around to see Tsuru there with her arms folded, the old woman giving her a stink eye. Metal Bat, Minoru, and Katsuki were nearby, the former holding an unconscious man dressed as a patisserie with a whiplash mustache.

"We found the villain responsible and DAMN!" Minoru said as he ogled the ginormous girls. "Today has been the best day ever!"

"Stare for more than I can tolerate and I will sit on you." Kyouka threatened, making the dwarfish boy gulp and look away respectfully.

"I see you've been taking my lessons on chivalry to heart, Mineta." Metal Bat noted, nodding in approval as he looked over Mount Lady. "As for you, Yuu...you wear the weight well."

Mount Lady teared up, her chubby cheeks blushing brightly as she scooped up her boyfriend in a big loving hug and peppered his face with smooches, much to his embarrassed protest.

Momo meanwhile, prepared to face Tsuru's disappointment…

Only to see the elderly woman smiling.

"I can see why Nemuri is so found of you." She smiled. "Yes, I gave you heck for being too modest, but at least now I see it comes from an…understandable place."

"Told you, mama." Midnight smiled, the older woman shooting her a look, but then smiling again.

"But I…" Momo began.

"This is good for you." Tsuru said, cutting off any discussion. "And if your career suffers because of those dirty old horn dogs in the HPSC? Well, they'll have to answer to me again."

"…Again?" The students asked.

"Who do you think helped me out during my costume debacle? Midnight msued.

"And not just then." Tsuru smiled. "the crushes…"

"SHUT UP!" Midnight screamed with a blkush on her face as she raced to silence her mother, who effortlessly dodged all her attacks and simply smiled at Momo.

"This is good for you. Remember that."

"Miss Tsuru does have a point, Yaomomo!" Mina chimed in. "I mean, you do use fat for your Quirk, and now you've got lots of it!"

"You know, maybe we can get in on Fat Gum's Super Diet Plan..." Miruko thoughtfully said, rubbing her chubby chin with a smirk.

"I don't know…" Momo said, pinching her giant belly.

"I know it's not exactly what you were expecting but sometimes even the strangest events can lead to the best outcomes," Tsuru said.

Momo, considering her options, nodded.

"Good point, I guess. I'll try seeing if this works for me."

"That's the spirit!" Midnight beamed as she patted the girl on the head. "Now let's get some grub, I'm still starving!"

Knightmare Lord A/N:

I hope you enjoyed the internships with some of the other characters. And I certainly enjoyed fattening up Momo, Mina, Kyouka, Midnight, Mount Lady, and Miruko. And yes, they'll all be keeping the weight.

Guess Hilda and Rosa won't be alone in the BBW department, huh?
