Disclaimer I don't own My Hero Academia or Undertale.

Authors Note: I realized I called Mei a man. Oops. Misspelling. Its horrible. Wow. I have more than a hundred followers for this story. Neat. I wonder if I'll ever get that amount of reviews too...Anyways, Izuku realizes he has crazy friends. He also realizes that he may or may not have created a miniature Hero Agency...

Rule 12: Do not steal from Pro Heroes. Unless they are Endeavor. Side note: Ochaco is really scary good with money. Side notes side note: Do not go to an expensive buffet/playground/arcade if you use the Number Two Heroes credit card. Apparently that is easier to track than taking a huge chunk of money out.

Touya Todoroki laughed with his siblings Natsuo and Fuyumi as they watched their mother Rei ask for Endeavors credit card.

Shoto had gathered his siblings the week after what Endeavor or Enji Todoroki had dubbed "The Sleepover of the Green Haired Brat," along with his mother last night to explain the prank he wanted to pull on his father. Rei, much to the children's surprise, had a twinkle in her eyes and a smirk upon her lips. She helped him plan how to go through with it. Natsuo and Touya had enthusiastically said that they would cover for him. Fuyumi grinned and suggested he do something with his new friends. With a laugh, Rei Todoroki had called all the mothers and suggested that the kids have a day out with her older children chaperoning with her husband providing funds.

Due to Endeavor leaving for a patrol he didn't see the cars pull up with parents and children.

It was when David Shield made the remark that his family was moving during the greeting that made the mood drop.

"Well, I guess it was a good idea for the children to get together for a day out! A farewell party for the kids and the adults can do their own thing!" Cheered a smiling Inko.

The Yaoyoruzu family suggested that the children go in the limo and could decide what to do on their own.

"So Shoto, whats the plan?" Asked Izuku with his signature grin.

"I want to use as much as my dads money as possible."

"Wait. Can't we get money out? We could have cash?" Ochaco had money signs in her eyes and the little girl started to drool.

The girls next to her looked at her wide eyed and tried to scoot away from her.

Ochaco turned to Shoto with a stern face with a dark aura around her. "Gimme money."

Shoto just stared at her and shrugged. "Okay! What does everyone else want?"

"Money for tools and babies-I mean gear?" Said a blushing Mei.

"I want a speed boat! A car! A helicopter! No a plane! Wait all of them!" Exclaimed an excited Melissa.

"I want a cat. A cat bed would be nice. Scratching post. Anything to do with cats." Muttered Shinso.

Shoto hummed. "I want a house to play in. I think mom would help me with that. It would be cool."

"That would be awesome! Like a secret base! I can help with that! We should also look cool. My mom and dad could help us with that. I want to try designer my Hero costume early so I want material for that!" Katsuki was jumping in his seat.

Izuku grinned. "We should do it all! A secret base with a cat room, a giant garage/warehouse, two workshops with one being mechanic and the other for clothing, a big kitchen, lots of rooms, I want a pool, at least one office for each of us! It would be like we are starting our own Hero Agency!"

"Wait a minute." Shoto held up his hand. "We can't have a Hero Agency. We're kids."

"It doesn't mean we have to have it labeled as an Agency! It would be like a huge prank!"

"Umm...Boys?" Asked a meek Ochaco.

"What is it?" Asked Izuku.

"Whats the matter?" Asked Shoto.

"We should get the money before we do anything."

"You're right we should probably do that."

Thirty minutes later at an ATM had Ochaco being given a huge stack of hundred dollar bills after forcefully taking the credit card from Shoto. Everyone was freaked out with her dangerous aura.

"Scary." Muttered the rest of the children in fear.

Once the girl finished counting the money to make sure everything was there, Touyas phone rang.

Answering the phone, Touya whimpered after hearing his mother. "I'm just going to ask this now. Did Shoto just withdraw money?"

"His friends did."

"That sounded more like a question."

"One of his friends is scary with money."

"Oh, which one? The Momo girl?"

"No. The Ochaco girl."

"Why did she take that much?"

"The children want their own secret base. They want a house with...a pool, a garage, lots of rooms, workshops, game rooms, a...cat room, guest rooms, offices, a big kitchen, probably a training room, a landing pad, an air strip, and anything else they can possibly think of."

"What?"

"Shoto and his friends want to be Heroes. He asked his friends what they wanted to do with the credit card. Izuku said they should do it all. Then the Ochaco girl said they needed money. She scared everyone."

"Oh. That's a lot. Does she have a plan?"

"I'm listening to Ochaco and the other girls using terminology that is going over my head. Izuku is making suggestions and is following their conversation."

"So you think they are being responsible?"

"Yes. I think so."

"Good. They can continue. Make sure to get something to eat."

Izuku and rest decided to celebrate with a party at a buffet that also split into a playground that had an arcade and goodie store.

Izuku decided to watch what his friends played and ate.

After two hours he had come to certain conclusions.

One: Shinso loves fish and can win anything involving a cat.

Two: Melissa loves pizza in any combination and is a master at puzzle games. He shouldn't play chess with her unless he wants to lose. She also loves to drive.

Three: Shoto likes soba noodles to the point it seems like he is obsessed with them and is good at throwing games.

Four: Mei likes coffee a little too much and should be restricted in having caffeinated drinks. Also, he shouldn't try and beat her with a gun simulator. He always loses badly. Maybe one day.

Five: Momo likes pastries more than other people. She likes burgers and other greasy foods. When he watched her, he learned that he probably shouldn't mess with her if she was playing a luck based game. She growls when she loses.

Six: Katsuki, of course went to the spiciest section of the buffet and then teamed up with him to do multiplayer games.

Seven: Ochaco loves mochi as much as Shoto loves soba. He should also try to stop them from arguing about their favorite foods. He also realized that she liked the driving games a lot and rarely lost.

The fun had to end when Endeavor looked at his bank account and they were all grounded.

Too bad Ochaco had a stash of money that he couldn't find and they all blamed the money on someone else hacking his account.

With Yaoyoruzu, Todoroki, Shield, Midoriya, and Bakugou mothers help they set up accounts for the children. To the parents surprise each of the children asked if Ochaco could take care of their accounts and help her make money.
