Izuku stopped as Super DimentOlive and Fawful entered the building. Super DimentOlive said this was an important stop. But why?
Bakugou started past him. "What's wrong, Deku? Scared?" He entered.
"Hey!" He rushed inside. "Super DimentOlive, can I ask why we're here? This building's been closed for years."
They were digging through things on a shelf in the back. "We uh...need some supplies. They're..."
Izuku saw them rub a silver-rimmed glass bottle between their pointer finger and thumb. It looked like there was water inside.
"Important supplies. Why don't you and Fawful watch the door? Bakugou could keep a lookout from the roof."
Bakugou sighed and climbed up a ladder to the roof access.
"Are you okay?" Izuku asked, letting Fawful guard the door on his own. "You're not happy like you usually are."
They grabbed their arms and raised their shoulders. "We're worried. We're worried about what's going to happen when she gets to us."
"Who's 'she?'"
"We can't tell you. It's too dangerous to know. The less you know, the better." Tears filled their eyes. "We just wanted a friend...Why did we have to make this all happen?"
Izuku heard a small thud and looked around worriedly. He saw Super DimentOlive had a long imp-like tail that had drooped thanks to their sadness. It was a pale red with two black stripes near the tip and one final stripe about halfway down it that went nearly to the end.
"Tail...?"
"Uh...yeah. It's an Oni Sprite thing. Some Power Sprites have them too, depending on their genes."
Izuku examined the shelf. He spotted more of those vials on a shelf that was too high for any of them to reach.
"Hey, there are more of those things up there. That's what you're looking for, right?"
They looked up, the bells on their hat ringing. "What are you doing, Izuku?"
"I'm helping you, of course. You might creep me out, but it's even creepier seeing you sad." He began scaling the shelves.
"You're going to fall," they teased.
"No I won't. I've done more dangerous stuff than this, believe me." He grabbed the vials. "See? I'm fine!"
The shelf cracked and snapped in half. Izuku began a quick decent. He came to a sudden stop.
"I'm not dead...?" He asked, shaking.
Super DimentOlive giggled. "We told you that you'd fall! You're lucky we caught you!"
"C-caught me? But I'm like five feet from the floor?"
"Is this a joke or..."
Izuku stared down at them, then followed their arm until he saw that they were holding him from the shoe.
"You have stretchy arms?! Why didn't you say something sooner?!"
"Why else did you think we were teasing you for? We knew you'd fall, so we were going to catch you. We wouldn't just let you splat on the ground like a tomato now, would we?"
"I really wish you didn't use that simile right there..."
They put Izuku on the ground and accepted the vials from him.
"So why do you need those?"
"Many reasons. But we do need to..." They glanced around, then pulled the lid off of one.
They drank it, getting a strange look from Izuku. They broke into a coughing fit afterwards and a bit of dark mist came from their neck ruff. They tossed the empty vial behind them.
"What was that?"
"Holy Water. It dispels darkness. We've been using it to heal the damage from the Chaos Heart."
The doors slammed open, Izuku and Super DimentOlive being startled. They both turned to find Fawful tied up in the corner and a female walking towards them. There were two burly men locking the doors by using a metal pipe and bending it into a knot.
"You must be Izuku Midoriya and Dimentio." She slammed her hand on the wall next to Izuku's head and brushed her hand under his chin. "You fit her description, but Dimentio looks a bit different than expected."
"It's Super DimentOlive, actually. And who are you?"
"You can call me Siren." She pushed Izuku down. "And you seem Dimentio enough, even the name..." She poked their chest and moved her hand up to their head and brushing it against their cheek. "Maybe she could let me keep you for myself, mister sexy."
"We're a they/them, actually..." Izuku could tell they were uncomfortable.
"How about a song, pretty boy? My tunes are irresistible."
"Uhh..." They tugged at the neck ruff. "Maybe later?"
She huffed.
Izuku took the chance to untie Fawful. He went back over to Super DimentOlive with Fawful.
"You know how playful you were being in that world you teleported us to?" Izuku whispered to the fusion.
They nodded, nervously watching Siren telling something to the two men guarding the door.
"Well, we need you to create a distraction so Fawful and I can get to that window up there and get out of here."
They followed Izuku's pointing finger to a window across the room. It was close to the ceiling, so they would need to crawl along the beams lining the roof to get to it. They also noticed the window was locked.
"It's locked."
"Then create a loud one so we can bust the lock," Izuku said.
"Okay..." They said, still keeping an eye on Siren.
"Her villain name is Siren, so she has a Quirk to match. Don't let her sing, because them we'd all get dragged along with her. Talk over her, be a nuisance. As much of a nuisance as you can. Just don't let her get a single note out."
"Talk over her, huh?" They grinned. "Oh, we can do that."
"Great. Fawful can get us up there. Escape as soon as I give you a thumbs-up, okay? A thumbs-up from me is the signal that you can get out of here. Got it?"
"Oh yes. We've got this. One distraction coming right up!" They passed Izuku the vials of Holy Water. "Guard these with your life."
"Got it. Come on, Fawful, let's go." Izuku and Fawful started up the ladder.
Siren returned. "So now that your little friends are gone...What do you say I take you out? A pretty boy like you would love a woman like me."
They stuck their forked tounge out at her.
"Wh-what does that mean?"
They tapped her shoulder with their tail.
"What?" She whipped around and saw nothing. "Who just touched me?" She turned back around. "Was it you?"
"Maybe."
She grabbed their tail before they could poke her again. "Ooh, a man with a Quirk. I love men with tails."
They got uncomfortable again.
She spun in a slow circle holding their tail so it would wrap her up when she spun, and moved closer to them. "Wrap me up and take me home, pretty boy; I'm yours." She brushed their chin, forcing them to make eye contact with her.
Izuku tapped his fingers together as Fawful picked at the lock. "Come on, Super DimentOlive, I know how obnoxious you can be. Just tap into that one more time for us, please!" He kept his voice down, but hoped his wish would reach them.
They uncurled their tail, sending her spinning away from them. "Women, huh? Think they're so pretty. We can be a pretty woman too!"
"There we go," muttered Izuku. "I kind of want to see how bad they embarrass her. But I also don't want to watch this."
Fawful shushed him.
"Sorry, am I breaking your concentration?"
He gave Izuku a side-eye glare.
"Sorry, I'll stop now."
"You can't just change your mind about being a man suddenly," Siren said. "That just doesn't make sense."
"We're non-bianary and bisexual and we can do whatever we want! Be right back!"
Izuku cringed. "This is not going to work, we're going to die."
Siren turned two her bodyguards when they hurried into the storeroom. "Find the kid and that green man. Puppetino will flip if she finds out I lost them."
"Ma'am, who was that strange person?" Asked the one on the left.
"That was nobody, sweetheart. Sometimes I forget you can only hear me when under my spell..."
The lights all flickered out except for one in the center of the room. Izuku looked over at Fawful, who brought out a flashlight and continued working at the lock. Super DimentOlive stepped into the spotlight. Izuku snickered when he saw them dressed in a short skirt and half shirt. They found some fluffy fabric and made a makeshift scarf from it.
"Boys are soo attractive!" They mocked, tossing theirself into the left bodyguard's arms. "We mean, you are really something! We have a thing for big burly guys like you, sexy man!"
"I-what?"
Siren rubbed her temples. "He's not a girl! You shouldn't be able to hear him!"
"We're a pretty, beanpole female just like you, Siren." They rubbed against the man's chest. "And we need strong men like this to protect us from dangerous heroes like Izuku Midoriya!" They dramatically flopped back into his arms, resting a hand on their forehead.
The man blushed. "I-I can protect you, miss."
"He's not a girl!" Siren snapped again.
Izuku chuckled, trying to hold back his laughter; for laughing too loud would give them away. "This is great. Siren's getting a taste of her own medicine."
Fawful angrily picked at the uncoorapative lock.
They formed a heart shape by the man's head with their tail. "Siren, keeping all the men for herself. Can she be anymore shellfish? We think not!"
Siren pulled them from the men's arms. "That's enough! What kind of sick game are you playing, boy?"
"We're a woman. But now we're a shark." They bit her hand, digging their fangs into it. She screamed and let them go. "Yay! Back to the man of our dreams it is!" They turned their back to the men and began shaking their hips. "Siren sucks, yes she does!" They sang mockingly.
"I think they just love making fun of people," Izuku pondered.
"Shut your pie hole!" Fawful finally snapped. "Fawful lost focus! Again!"
Izuku kept quiet and Fawful continued his work. Izuku watched Fawful pick at the lock when Super DimentOlive started doing a sexy dance.
"Sorry, Fawful. Can I help?"
He sighed. "Not working." He looked around. "Make them do it loud."
"You want Super DimentOlive to be louder now? Okay..." He tapped his chin. "What to do..."
He saw Super DimentOlive glance at him, so he signaled for him to be louder by raising his hands into the air. They nodded. They tossed off the scarf and tore off the clothes. Izuku wondered how they were still wearing their usual outfit underneath, but decided not to question.
The bodyguard blinked a few times. "Wha...? Where am I?"
"He broke out of my spell?!" Siren screamed.
"Haha! We turned him gay! Take that!" They begun doing a funny jig. "Dadatatahoora!" They spun and tossed confetti into the air. "Ay?"
"Get him!"
The left bodyguard sat there, stunned as the one to her right charged for Super DimentOlive.
"Why was the clown in the hospital?" Super DimentOlive asked.
"What kind of joke is that?!"
They jumped over the bodyguard. "Because he broke his funny bone!"
The bodyguard grabbed them by the ruff. "Subject secured, ma'am."
"Thank you! Finally!"
They shoved the pointed tip of their tail up his nose. He screamed and dropped them. Their tail gave him a bloody nose.
"Must I do everything myself?!"
"Only if you want to. Let's party!" They grabbed the shelf behind them and winked at Izuku.
"Fawful, now!"
Fawful nodded and four spider-like, shadowy limbs sprouted out of his back.
"It won't be a party without the fireworks!" They tossed the shelf at her.
She dodged, but as is crashed against the floor, Fawful used the bug legs to rip the lock off and slid open the window. He gave them a thumbs-up.
"Well, looks like it's time for this parade to end with a flash!" They elongated their arm to grabbed the lightbulb and tossed it at the ground. It sparked brightly for a second, and during that time, they jumped up to the beams to join Izuku and Fawful.
"How was that for a distraction?"
"The dance was a little much," Izuku said.
"Let's get out of here!" They kicked the window out of the wall, creating a bigger hole.
"Why didn't you do that before?!"
"We were having fun! Hey, Siren!"
Siren glared up and growled. "There you are! Get them!"
"Thanks for being such a good audience!" They wrapped their arms around Fawful and Izuku, carrying them off the beam. "Ciao!" They gave her the bird as they leaped through the hole.
Izuku watched behind them for a bit before realizing the group was safe.
Super DimentOlive started laughing. "We haven't had fun like that in a long time! That felt good!"
"Is it okay if I give you another name?" Izuku asked. "Super DimentOlive is a mouthful."
They slowed from a run to a walk. "Sure. If you want. We don't care."
Izuku pondered the decision for a moment. "What about Ninshisho-no?"
"That sounds Japanese. We don't know what it means though..."
"It stands for uh...'friendly person?'" Izuku lied. It stands for 'demented,' but he wasn't going to tell them that to their face.
"Oh! Well then, we love it! From now on, our name is Ninshisho-no!"
"You can shorten it to 'Shi' if you want."
"Shi it is! We're Shi! Shi!" They skipped happily along until they were suddenly grabbed from behind and pulled into the sky. Luckily, they dropped Fawful and Izuku, but the landing had hurt. "Find shelter! Now!"
Izuku rushed off with Fawful following behind. He ducked around a corner and slid off the lid to the sewers.
"What was the flying about?" Fawful asked. "They cannot do the fly. Right?"
"Get in."
Fawful started down the ladder, climbing back up a bit to ask, "Coming?"
"In a minute. I want to see who we're up against."
Fawful exited through the sewers. Izuku peeked around the corner and saw Puppetino holding Shi in midair with a sort of string. They were hanging by their tail.
"Dimentio I-" She grimaced. "Who the h#$% are you? You're not Dimentio!"
"Finally, somebody who got it right." They held out their hand. "We're Sh-" Fear struck their eyes. "P-Piper? B-but you...you were..."
"Killed? No, I lived. Em didn't though. I hope you're happy. Plus, now I know I was right. How does it feel to be the one trapped and suffering?"
"Peppi! We're so glad you're alive!" Tears filled their eyes. "We've been living with that guilt for years! But now you're here, and not a single burn on you!"
"Listen here, Didi. I won't stop until all of Japan is mine. I'll kill them all, one by one, and make you watch. I'll keep you safe for now, but you better watch your back."
Shi fell to the ground as the string vanished. "You wouldn't!"
"I would, and I will. Say goodbye to your friends, because this might be the last day you will ever see them again." She held up Bakugou, Ochaco, Mina, Kaminari, and Momo. "I might kill these ones first, so look out. Toodles!" She vanished.
Izuku ran over to them when he saw they were shaking. "Shi? Are you okay? Who was that?"
"That was her. The person we're so scared of." Their hands were resting on their chest.
"We'll stop her."
"Do you still have those vials of Holy Water?"
Izuku held one up to them. "Yep. I made sure not to lose a single one."
"Great, because you're going to learn how to undo puppetization." They held up the puppets Piper had displayed to them.
"Did you steal those from her as she was talking?!"
"Just because we were a mercenary for a while doesn't mean we got all of our money from jobs. We became a master thief from that."
"I also know where we can hide for now," Izuku explained, leading them to the sewer.
"Let's stop Peppi, together."
"We got this, Shi."
