"More and more heroes have vanished as of today. If it keeps happening at this rate, the world'll be stripped of heroes before Saturday. And now to Daryl for the weather."

Inko entered Izuku's bedroom. "Izuku? Are you alright? You haven't really left your room lately."

"Huh? Oh, yeah. I'm fine. I'm just worried about Mimi. I accidentally let her get away, and now more heroes have vanished! They started disappearing the day she escaped the prison. Could she be behind this?"

She sat down on the bed next to him. "Oh, Izuku. It's not your fault. They'll catch whoever is making the heroes vanish, and you won't have to worry about it anymore. I know I'm pretty worried too. We can worry about it together."

"Wait...that's it! Thanks mom!" He gave her a quick embrace. "Why wait when we can catch the hero-snatcher ourselves!"

"That seems pretty dangerous. Are you sure you should do this?"

"If we wait any longer, all the heroes will vanish. The sooner, the better. I'll be extra careful, okay?"

"Izuku, don't forget to eat lunch, okay? I know I can't stop you from doing hero work since that's all you wanted to do since you were young, but I can still look out for you. Be careful."

"Thanks, mom. And I will." He embraced her one final time and exited the house.

She sighed. "They grow up so fast, don't they?"

Izuku met with his friends in their usual park meeting point. Olive had forced Dimentio to come with him.

"Um," Izuku said as he came near. "Why is Dimentio here?"

"He's a villain, so he would know villains! If we have a lead anywhere, it'll be because of Dimentio. After all, he's a mastermind villain."

"Don't flatter me," he responded.

Olly hung upside down in one of the branches of the tree nearby. "He suggested starting our search at the school, since Aizawa and All Might were a few of the first heroes to vanish." The tree barked. "Oh, I also brought my dog, Stapler. He could use his nose to help us search for clues!" He sat upright on the branch, Izuku finally noticing he was in his small form. "And being in my small form will help with stealth, along with Mineta's Quirk."

"He's really stubborn about me using my Quirk for stealth," he said.

"I mean, we'll be trespassing into a highly-guarded school building, so stealth is crucial!"

"What's with you and stealth?" Izuku asked.

"Scissors told me stealth is important. You can use it to learn your enemy's plans, or to sneak into a school..."

"Maybe I need to start locking my bedroom door at night when I go to sleep..."

"So let's go see that school already," Dimentio pressed. "I'm getting impatient."

The school had a thick silence over it, choking any sound that dared draw near. It had been closed since this morning, and Izuku could already tell something was wrong. To enter, a brave should would need to hop the fence and open the gate from the inside. Ochaco, the Origami Twins, Kaminari, and Tsu offered to do the job.

Izuku felt something soft brush his hand, and he jolted away. To his surprise, it was Stapler. He was a black husky, the usual white instead being a glimmering silver. A red collar bore his name with a golden tag with Olly's insignia pasted onto the front. Izuku brushed the dog's body from the head to his lower back. He brushed the hair off of his hand.

"Oh, yeah. Stapler's kind of shedding at the moment. You know how it's getting close to winter now."

"Be careful," Tokoyami warned. "People won't like hearing that heroes in training trespassed into their own school."

"We'll be fine," Olly said.

"Wow, the school seems so creepy when it's closed like this," Olivia said.

"Yeah," Ochaco agreed. "Let's do this quickly. I still can't believe that I'm breaking into UA."

After using their Quirks to head over the gate, they headed inside. Olly used Fold of Life to make a makeshift key to get through the doors. They headed to the control room where Kaminari used a small, almost twelve hundred-bolt shock to deactivate the school's defences and security cameras. The rest of the group entered and joined them.

"Alright, we need to investigate the entire school, starting first with the classrooms that were run by heroes," Dimentio explained. "They may have left a clue behind. If they were clever, they would have been especially careful to cover their tracks. However, based on how quickly this has been happening, we can say that they were not being clever at all."

Olly suddenly jolted. "Magic. Strong magic. It's everywhere." He hurried off.

"Wait for us," Ochaco called, and he stopped in the hall.

He faced them. "The residue is very recent. Recent as in yesterday. The tracks are still fresh." Stapler seemed to be able to sense their magic as well, as he started off without his owner. "Stapler's on their track. We mustn't wait any longer!" He hurried off again.

"Dang, he's fast!" Izuku panted after him.

Olly stopped in Aizawa's classroom, their homeroom. He slowly crept over to the cabinet that held pencils and other necessary supplies if someone were to leave theirs at home. He reached for the handle.

"What do you sense, brother?"

He grabbed the handle and turned it, taking a deep breath before tossing it open. There was a high yell and a few sparks flew from the cabinet. Olly screamed, Izuku noticing his crown fly off for a moment from his sudden movements and land back onto his head lopsided. He fled, taking shelter behind Izuku. Olivia did likewise when her brother had screamed. Izuku went to the cabinet and pulled out a jack-in-the-box with a horrifying clown face painted horribly onto it.

"Hm..." Dimentio mumbled. "Hurried plan, horrible painting skills, a jack-in-the-box...This seems almost like something I would do, if it weren't for the quick take-and-run plan of theirs. But yet, this seems almost familiar...They're being too careless."

"Do you know who did this?" Izuku asked.

He shook his head. "Just rambling. Sorry."

Izuku held out the jack-in-the-box to the twins. "It's harmless, see?"

Olly flinched away from it. "Scary..."

"Sorry. I'll get rid of it." Izuku dropped it on the ground and stomped it to bits. "See? It's gone now."

"Pafetic," Dimentio muttered. He slapped his hand over his mouth. What a terrible time for his lisp to slip out! He felt his face grow warm, then relaxed when nobody seemed to have heard it.

Olly went into All Might's class next. He studied the room for a minute. "Our little villain won. There was a skirmish here between them and All Might." He folded small versions of All Might and the villain, who was completely black as they didn't know who it was yet. He moved All Might towards the board and the villain more towards the door. "All Might was working on preparing the class. The villain had probably just captured Aizawa at this time."

The villain moved closer to the ceiling. Izuku pondered how Olly knew this information just by sensing magic.

"They were floating p there, waiting for a time to strike." The All Might turned around and started heading for the desks. The villain landed right on top of him, both of the origami figures landing flat on the ground. "And they captured him too. He wasn't expecting it. They had a battle. Based off of how much the villain was moving around, I say they were playing defensive whilst All Might was attempting to stop them. I can't capture the entire battle. The magic layers over itself during the battle, since they were dodging around in a small space. But either way, All Might lost."

"How did you get all of that by sensing magic?" Izuku finally asked.

"Magic is inside of you. It follows the shape of your body if it's peaceful. Yours is for sure, Izuku. This makes it easy to tell where someone's been and what they were doing there. All Might is a bit hard to see. His looks damaged. It's mainly mixed up near his left side...It looks pretty bad there. I wonder if he's alright."

Izuku felt himself beginning to sweat. "Oh, really? You can tell where someone gets injured?"

"Only if their magic is affected. Dimentio's is very corrupted, and our mystery villain seems to be corrupted as well; but not as bad."

"How come you don't know who the villain is then?" Bakugou snapped. "If you can see them, you know who it is, right?"

Olly sighed. "I wish it was that easy, Bakugou, but it's not. I can't really read corrupted magic. Dimentio's already a problem, and the more corrupted magic there is nearby, the more mixed up my sense gets. If we can find an area where their corrupted magic is the strongest, we should be able to tell where they went. Speaking of which..." He peeked out the door. "It gets stronger that way. We should head there next."

"Looks like we didn't need you after all, Dimentio!" Olive joked. "Olly's getting us a pretty good lead already!"

"Excuse me? He wouldn't have that lead if I hadn't recommended checking the school first!" Dimentio rolled his eyes.

Olly stopped in the auditorium. Izuku noticed he began to shake. He came over to the tiny king and placed a hand on his shoulder.

"Are you okay? You're shaking."

"Th-the..." He placed his hands on his head. "Too...awful..." He exited the auditorium.

Everybody followed except Dimentio.

"Olly?" Olivia asked. "Are you okay?"

"Yeah, I am now," he panted. "It was too bad in there. That was the last place they were before their magic just suddenly cuts off. They may have teleported to cover their tracks to their hideout."

Dimentio was pacing around the room when Izuku returned with Bakugou. He stopped for a moment and grabbed something from his pocket. He held out his hand and blew purple glitter at the ceiling, it settling all around the room. Izuku saw a small glimmer in the light, and noticed Dimentio spotted it too; as he started walking towards it. Izuku joined his side. Dimentio flicked his finger across the glimmer, it making a sound like a harp and wriggling slightly from the force.

He rested his face in his hands. "Oh no...It can't be her. She died, she can't be here."

"Who died?" Izuku asked. "Who's taking the heroes, Dimentio?"

"I can't tell you, I really can't. It's personal." He removed his hat and fixed his hair. Izuku noticed that his white roots were more visible than before now. "I need to stop her. What does she think she's doing?"

"Deku," Ochaco said, "we should leave."

"No!" Dimentio shouted. "She'll find us. We need somewhere to hide."

Olly poked his head into the doorway. "Izuku? You should check the news. All the villains in the prison had been freed."

"What...?" His gaze went to Dimentio again. "Freed?"

"Yes. And there are no more heroes around to stop them."

Ochaco nodded. "All the heroes are gone."

Author note: Olive's voice actor: Alex Brightman

Dimentio's voice actor: Keith Silverstein

Super DimentOlive has Alex Brightman's voice, but with a hint of Keith Silverstein in it, along with a robotic tone.

I thought that would be helpful since I finally decided on Olive's voice.
