"Ow." Jiro slowly sat up, holding her throbbing head.
"What the hell-!?" Kaminari groaned, brushing bits of cement from his hair. "-what happened!?"
"I don't know." Shoto answered, looking around the room they had fallen into too. It was large as a gym. Class 1-A collectively began picking themselves up from the floor, checking on one another to make sure no one was injured.
"Where are we?"
"This place is creepy." Mineta shivered, thinking it looked like something out of a horror game.
"I don't know." Kirishima looked up, the hole in the ceiling was too high up for the class to climb by hand. The sharp-toothed hero glanced over at Katsuki who was leaning against a fallen piece of cement holding you in his lap.
With you knocked out, Kirishima knew his explosive classmate would not part with you meaning Katsuki couldn't blast his way up there.
"Man!" Kaminari rubbed the back of his head. "We were so close!"
"There is no use in complaining-" Ida turned to his class. "-we need to keep moving. Whoever brought us here must have known we escaped by now."
"Ida's right." Momo breathed through her nose, "It's best to keep going."
"We don't even know where we are!" Kaminari argued.
Katsuki fletched; his face instantly blushing as he felt you snuggled closer to his body. You could smell his familiar scent, it brought you comfort as you tried to steal his warmth. Katsuki pants tighten feeling you so close.
"S-Stop that!" Katsuki harshly whispered, causing you to chuckle. His red eyes widened for a moment, hearing the sweet sound. "Your-!?"
You yawned, sitting up you stretched your arms.
"(y/n)!" Mina breathed in relief, seeing you moving around.
"Hey!" Kirishima grinned, "So good to see you alive!"
"Mm." You hummed, still sleepy. "Where are we?" You wondered, looking around the stone room.
"We don't know." Momo sighed.
"How did you all manage to fuck up our escape so quickly?" You groaned rubbing your face, not bothering to remove yourself from Katsuki's lap. Asui and Jiro blushed, avoiding eye contact.
"I-I don't see you doing anything!" Sero pointed.
"Oh, I'm sorry-" You flashed a grin, "-I was busy being a fucking extension cord to free us, what the hell were you doing again-!?"
"Alright." Ida stepped closer, "This is no time to fight, we need to come together and figure a way to get out of this place."
"Well, isn't that a door?" You asked, lazily pointing across the room.
"That looks like a whole ass trap-" Sero replied, "-just waiting to happen."
"Yeah!" Ochaco agreed, "We are not stupid enough to fall for that lame trick!"
"But you did fall for the old floor falling out from under you?" You questioned, causing the two young heroes to blush shades of red.
"Well-Well..." Ochaco awkwardly laughed rubbing her arm, letting the conversation drop.
You stood up, walking over to Mina who held her shoulder, her face clearly showing she was in pain.
"You ok?" You asked her, Katsuki remained where he sat, his sharp eyes locked onto you as his mind raced on whether or not the obvious door was the answer to getting out of here.
"Yea-Yeah." Mina breathed, you ignored her protesting, gliding your fingers over her arm causing her to whimper.
"Your shoulder is dislocated." You stated.
"Wh-What!?" Mina gasped.
"We need to get you to a hospital!" Ida quickly jogged over; you rolled your eyes.
"It's not like she'll die." You say, "But this is gonna hurt like a bitch."
"What is-?" Mina frowned, not understanding, before she could react you placed a hand on her back and the other firmly gripped her arm. Quickly you popped the shoulder back into place. Mina gasped out in pain, dropping to her knees.
"(y/n)!" Ida harshly protested.
"What?" You asked, "I had to pop it back into its socket."
"You're not a medical professional!" Ida lectured.
"Oh, I'm sorry-" You glared, "-would you rather I wait for a magical rescue and allow the Mina to lose mobility in her shoulder?"
"You don't know that would have happened!" Ida replied.
"No-" Shoto spoke up, "-(y/n) is right, if a dislocated shoulder is left untreated it can damage the surrounding area, causing loss of mobility."
"But-" Ida went to defend himself.
"Why are you bitching at me when we are still standing in our kidnapper's creepy dungeon?" You asked, "Complain when we are standing outside."
"You-" Ida was cut off but a rushing water sound. Mina, you, and Ida all looked to your left, seeing a flood of green swallow you three whole.
"What the hell!?" Sero jumped back, getting out of reach of the thick green slime. Katsuki was already on his feet, eyes wide searching for you.
"What the hell is this stuff!?" Toru shrieked, seeing the goo touch her foot. She instantly jumped away; thick slime oozed down her shoe.
"Whatever it is it has Mina, (y/n), and Ida!" Ojiro pointed the three of you out, who floated into the goo. Katsuki let off a few tiny explosions inside his hands.
"Bakugo don't!" Momo shouted. "You could hit one of them!"
"Damnit!" Katsuki cursed, knowing she was right.
"Why aren't they fighting to escape?" Jiro muttered to herself. Katsuki looked from her to you, questioning the same thing.
"Who cares!" Katsuki cursed, knowing he just needed to get you out.
You breathed in, shifting your legs feeling the softness of Katsuki's sheets. Caramel with melted sugar mixed in your scents, nuzzling your face into the crook of his warm neck your leg draped over him. Your muscles felt like jelly as his strong arm wrapped around your torso. Lightly he squeezed you, relaxing you further.
"(y/n)-" Katsuki's husky voice graced your ears.
You could honestly die happy at this moment...
"-(y/n) wake up-!" Katsuki's belted out, "-damnit!" He cursed, his legs sinking into the muck of the giant slime ball that was growing at a rapid pace, filling the room with the UA students inside it. His hand gripped around your wrist.
Katsuki's eyes narrowed, seeing small glowing dots being drawn from you and absorbed into the goo. "What the fuck is this?" Katsuki breathed, receiving flashbacks to when he was attacked by the sludge villain. He shook his head, refusing to feel weak right now. "Now flex tape!"
"Wh-What did you call me!?" Sero yelled standing behind Shoto who used his quirks as a barricade from the slime, pulling on the tape wrapped around Katsuki's waist, bringing him flying backward through the air, and you to freedom.
Sero guided the two of you the best he could, Katsuki broke free of the tape landing in front of Sero with you tightly in his arms.
"What did that thing do to her!?" Sero noticed your closed eyes and limp body.
"Shut up!" Katsuki snapped, glancing at his classmates who were all trying to contain the thing.
"Does this stuff look alive to any of you!?" Sato questioned, jumping away from another wave of goo shooting towards the sugar hero.
"This must be a quirk of some kind!" Ida realized.
"No shit." Katsuki cursed.
"We need to figure something out!" Jiro called backing up, "We are losing too much ground! Pretty soon we won't have any place to stand!"
"Nothing is working against it!" Midoriya replied, "The quirks we can manage to use are almost useless against it!"
'Their quirks.' Katsuki thought, taking in a deep breath he tightened his grip around you for a split second before yelling out: "Shitty hair!"
"Stop calling me that man!" Kirishima turned, his red eyes widened, and his arms instantly flew out. Katsuki tossed you through the air to him.
"You better not let anything happen to her-!" Katsuki warned, "-or I'll kick your ass!"
"What are you-!?" Kirishima didn't get to finish talking before Katsuki blasted himself through the air, using his quirk against the slime.
"Not even Kacchan's explosions work" Midoriya breathed, seeing how the slime seemed to be unaffected by the blasts. "Shoto's ice isn't strong enough to freeze it."
"Fuck!" Kaminari cursed, jumping away from the wave of ooze flowing over the rumble he stood upon. "High ground isn't working any more guys!"
"Kiri?" Kirishima snapped down, seeing your eyes fluttering open.
"Wha-?" He breathed, heart fluttering hearing his new nickname on your lips.
"Put me down."
"I-I can't." Kirishima shook his head, knowing Katsuki would be pissed if he did.
"Do you trust me?" You asked,
"I...of course I do but-"
"Put me down."
Kirishima went to set you on your legs, but they felt like cooked noodles, you instantly fell to your knees.
"(y/n)!?" Kirishima held his arms in the air around you ready to catch you should you fall. "What did that stuff do to you!?"
"I-I don't know..." You licked your lips; you could have sworn you were inside Katsuki's dorm room just a few moments ago but...that wasn't right, slowly reality came back to you. Holding your head, you locked your eyes with Shoto. Kirishima watched as the two of you seemed to read each other's minds.
Suddenly Shoto and you released your ice quirks, shooting them forward encasing the slime inside the sparkling display. Kirishima's mouth hung open, seeing the two different ice quirks side by side was amazing. Shoto's quirk was rough, leaving trails of spikes when he used his ice but you...your ice quirk was a smooth sheet of ice.
"What the hell shitty hair!?" Katsuki cursed, dropping down beside them. "I told you-"
"Guys!" Jiro pointed, cutting Katsuki off. The class turned to watch the ice begin to crack.
"No way." You breathed, there was no way anything could break out of the dome created by two ice quirks, it should have been too thick. After a still moment, filled with pounding hearts, everything was silent.
"(y/n)-" Katsuki said, "-can you remove the ice?"
"What!?" Kirishima gasped.
"No way!" Kaminari agreed, "We need to run."
You understood where Katsuki was coming from, something didn't feel right. The last thing you all needed was another surprise attack. Mina and Ida were out cold, you didn't understand how you were even awake right now. You felt so exhausted like all your energy was sucked dry from your body you just wanted to collapse.
You reached out, evaporating the ice.
"(y/n)-" You class protested but you ignored them, once the steam cleared Katsuki sharpened his eyes.
"I-It's gone!" Your class gawked.
"We need to go." You commented, feeling uneasy as the nerves on your back were raised.
"Right." Your class could feel the cold sweat on their backs. Where did that thing go, and when would it appear again?
Mina and Ida were picked up, Katsuki wrapped an arm around you helping you steady yourself.
"(y/n)?" Katsuki saw your confused face. "What-?"
"I-" You started. "-I could have sworn we were just in your dorm room."
"My dorm room?" Katsuki frowned. "What?"
"I think it's a side effect." Midoriya butted in, annoying Katsuki. "(y/n) when you and the others were trapped inside that stuff, we could see this substance-"
"Substance?" You felt confused, and a little grossed out, "I need a shower now."
"I think-" Midoriya breathed, "-whatever quirk that was, it was stealing your energy or something, that must be why Ida and Mina are out cold."
"But why is (y/n) up?"
"I-I don't know." Midoriya shook his head. "But I have read about some quirks having the ability to put their victims in a trance in order to siphon off them."
"That must be what happened." Shoto agreed.
"I feel dirty." You whined, causing Katsuki and Kirishima to smirk.
"Let's stop standing around-" Katsuki stated, "-we need to move."
