The manga has really been something lately, hasn't it?

"Here's his things, I probably missed something so if you need something just text or call me, okay?" Aizawa handed Izuku and a large backpack over to Mirio.

"Don't worry, sir!" Mirio saluted. "You take care of the villains, we'll be just fine here!"

Izuku wiggled his way out of Mirio's arms. "Eriiiii!"

An excited shout came from the other side of the apartment. "IZUUUKUUU!"

"The Wild Wild Pussycats should come by with Kota in a little bit." Aizawa explained urgently. "I can't guarantee we'll return… but if I-"

"I'll take care of Izuku until you come back." Mirio interrupted. "And you will come back, Eraserhead-sensei. Go protect your fellow heros. I hope your students do well."

"So do I." And with that, Aizawa left.

"Mirio!" Izuku and Eri came running back to the front door, each grabbing Mirio's hand and pulling him into the apartment.

Both of his parents were heros. They were gone to help with the operation. Mirio and the kids had the place to themselves.

Mirio hoped it wouldn't stay that way.

"Mirio, can you cut up this apple please!" Eri handed the fruit to him.

Mirio smiled. "Yes, of course! Do you want an apple too, Izuku?"

"Yeah! With peanut butter!"

Mirio pulled out a knife and cutting board, swiftly cutting up the two apples and giving them to the kids.

"We should make a fort!" Izuku declared.

"A… fort?"

"Yeah!" Izuku bit one of his apples and made a box shape with his hands. "You make a building out of pillows! They're super-duper comfy!"

"Oh!" Eri lit up.

The apartment door buzzed. Mirio walked to the door, leaving the two to plan their fort and finish their apples.

"Hello!" Mirio greeted.

"Hi. Mirio, right?" Mandalay greeted. "Sorry, I've gotta go. This is Kota - Kota, where- oh, there, why are you hiding? - Here's his overnight bag, and my number if you need something. Everyone else already went ahead, so-"

"Good luck, Ms. Mandalay." Mirio nodded. "I'll take care of Kota, don't worry."

"Thank you for this, on such short notice, too. Kota, you behave yourself for Mirio, okay? I love you."

Kota nodded, somewhat reluctantly. "Come back, okay?"

"I will. I promise. Bye, kiddo."

Mirio let Kota into the house, setting his bag in the living room. He returned to the kitchen to see the three kids sitting in a circle, a paper and a red crayon sitting on it.

"We should have lots of pillows inside, and make it really big!" Izuku said, reaching for the crayon.

"Idiot." Kota snatched the crayon away. "We need to know what our materials are first. Then we can plan."

"If we take the sheets off the beds we will have twice as many blankets." Eri mumbled.

Izuku gasped, and pointed at Eri. "You're right! Then we can use the soft stuff for inside!"

"Whoa, kiddos." Mirio said, grabbing the empty plates off the table. "We are not going to take the sheets off of my parents' bed."

"Okay, just my bed then." Eri said. "And Mirio-kun's."

"Do you have any fairy lights, Mirio-san?" Kota asked the older boy.

Mirio thought about it for a second. "Mm, probably."

"Go get it." Kota ordered. "And the other supplies to."

Mirio chuckled. "Aye aye, sir."

They had the fort built in a short amount of time, considering the size of three of the four builders. Kota and Izuku hung the fairy lights with care, and Eri helped Mirio pick out a movie to watch on his laptop.

"That one." Eri pointed at a movie that had a girl on a broomstick, flying with birds over a sprawling town.

"Kiki's Delivery Service?" Mirio nodded approvingly. "Sounds good to me."

They watched the movie, ("I wanna be a witch," Izuku said decisively. "And ride a broom like Kiki."), then Eri demanded Mirio teach her how to braid hair, using Izuku and Kota for models. Izuku gigglingly tugged on the tiny braids. Kota scowled and pulled them out everytime Mirio finished one. Eri then smacked him, and tied each of them off with a colorful ribbon. Mirio braided Eri's hair, ending it with a pretty red bow. Then Eri (with Izuku's assistance) decorated Mirio's hair with many colorful hair clips.

Izuku fell asleep at some point.

"Mirio-kun, can we make cookies?" Eri asked.

"I bet I could make better cookies than you two idiots could." Kota grumbled.

"I don't think so!" Eri replied confidently.

"Are you guys just going to leave Izuku out?" Mirio asked.

"He can be the judge!" Eri suggested.

They looked at Kota, to see if he was in agreement.

Kota sighed. "Sure, whatever."

And so the bake-off began, leaving Izuku snoozing in the fort. Mirio helped the two get things off of high shelves, and made sure they didn't make too much of a mess or burn the place down. Kota insisted on doing everything himself, even reading the directions (which he was surprisingly efficient at. Only a few times did he grudgingly ask Mirio to read a few of the harder words) Eri asked Mirio for help with a lot more.

After a flour spill, a few dropped eggs, eating half of the chocolate chips, and trying to eat the cookie dough ("Nope, nope, only adults can do this," Mirio ate a spoonful.) and about an hour of waiting.

"It's ready." Mirio said. "Go get Izuku."

The two crept into the fort, then jumped on top of Izuku. "COOKIES!"

"Arghgitg" Izuku woke abruptly to the air being squished out of him. A few tears welled up. "Mirioooooooo!"

Mirio appeared. "Did you guys jump on him?"

Izuku wailed, nodding. Eri and Kota glanced at each other guiltily.

Mirio sighed. "Come on, Izuku, let's go get some cookies, yeah?"

"Cookies?" Came the tearful reply.

"Yup."

"He's gonna like mine better!" Eri cheered.

"No he isn't."

"Yes he is! I'm his favorite!"

Kota scoffed. "No way."

"Yes way!"

Izuku ate both cookies with equal vigor. "More?" he asked Mirio hopefully.

"Nope," Mirio answered, mouth stuffed with cookies (A/N: mood). "You'll get sick, kiddo."

"Which one was your favorite, Izuku?" Eri asked.

"Um…"

"The second one, right?" Kota asked.

"No, it was the first one, right?" Eri pushed.

"I… they were both yummy!"

"But which was better?"

"Same cookie!" Izuku giggled.

"They did use the same recipe." Mirio muttered.

"Oh." Eri frowned.

Kota shrugged. "I'm still his favorite."

"No!" Eri yelled. "I am!"

"I am!"

"I am!"

"Idiot, you're wrong!"

"You're an idiot!"

"You're both my favorite." Izuku said absently. "Like a, um, Kota-ani and Eri-ane!"

The two froze. Mirio almost spit out his cookies in surprise.

"Uh." Kota spoke first. "You're my favorite, too, Izuku...-otouto."

"That's what I was gonna say!" Eri chimed in. "Izuku-otouto!"

Izuku giggled.

Japanese: ani- big brother (suffix); ane- big sister (suffix); otouto- little brother (suffix)

Mirio is written way out of character and I'm hungry for cookies now.

Appreciate you all! ~BP
