Yuko stood to the back of the police, her hand on her hip. She scanned the area, as well as the house belonging to the Hassaikai, her body tense and ready to act.

"Once they've read the warrant, charge in! I'm counting on everyone to move swiftly." The Chief called back to them.

Yuko slipped her mask over her face, making sure her hood was secured, before her crimson eyes returned to the gate in front of them. She couldn't shake the feeling that something was up, and she knew Night felt it too.

The large reptile was currently hidden in the clouds above, watching below. Though he wasn't the stealthiest on the ground, the sky was a different story. That was his kingdom, he knew how to maneuver storms, and stay hidden in the clouds. When it came to flying, Night knew what he was doing.

'Yuko!' The girl snapped her head to look to the Chief, before looking over the group, her crimson eyes snapping to the gate, before she quickly understood.

"Wait--" She was too late as a large, muscular man, wearing a mask slammed through the gate, knocking back a few police officers, -who were fortunately caught by Izuku and Aizawa.

"What do you want?" The man asked in annoyance, "bringing all these people so early in the morning..." Yuko's eyes narrowed on the Hassaikai member, her mind reeling as she watched his movements.

The Hassaikai sucked in a breath, the heroes all taking a defensive stance.

"Did they already notice us?" Rock Lock questioned.

"Forget about that, let's just all hold them back together!"

"I feel a little more awake now. Jeez..." The larger man muttered, his feet shuffling under him, before he reeled an arm back, it growing in size.

Yuko's eyes instantly widened, rushing forward, -alongside Ryukyu, and holding her arm out, "get back!" She ordered, 'Night!'

"What do you people want?!" Dust circled the group, the officers kneeling as they held up their shields.

As the dust cloud cleared, Night could be seen with his wings spread out, blocking the group behind him, with his jaw locked around the Hassaikai's arm, his teeth sinking itself in his flesh. Ryukyu stood beside him in her dragon form, her fist holding the man's neck. The two held back the Hassaikai member, as Night growled in warning to the large man.

"Anyway," Ryukyu grunted, "we shouldn't split up our forces here. Ryukyu agency will take care of him." The woman informed, slamming the man down, leading to Night taking his claws to hold him down, as Ryukyu stepped back, looking at the large beast, a little taller than her.

"The rest of you go now, while you have the chance!" She ordered, Yuko looked back at the dragon-formed woman and Night.

"Okay everyone, get in! Quickly!"

"Night'll stay here to help you!" She looked back at her partner and best friend as he growled at the Hassaikai, "listen and protect." She ordered, before quickly running to catch up with Fatgum's agency and the others, drawing her staff in the process.

The girl ran alongside Eijiro, as the Chief called out out to the house, warning them of his warrant.

One of the three men standing in front of them, blocking their way, went unbothered, waving his arm and sending needles made of leaves from the bushes, at them. He was cut off as one of the heroes struck him, stopping his attack.

Yuko huffed as she watched multiple Hassaikai make their way out, trying to stop the charging group. The girl ran past the police officers pushing the Hassaikai back, following her companions.

"Leave them to us and go on ahead!" Mr. Brave ordered as he sent a few of the men back.

"We're counting on you!" Nighteye called back to them, Yuko quickly swiping the feet of a few men that stood in their way.

"It's an emergency! Excuse us for not taking off our shoes!" Fatgum shouted as they pushed through the front doors of the Hassaikai's household.

"They haven't done anything suspicious yet!" The BMI Hero pointed out as he looked back.

"I'm getting kind of worried, man." Rock Lock expressed, "we have no choice but to keep going now that we've started, though."

"I wonder if someone leaked information to them." Tamaki huffed, "I feel like they're gathered in one place for some reason..."

"If someone had, I think they'd be avoiding us more smartly." The Chief called back to him, "they should all be used to working together with one will already."

"They devote their all to their bond with their boss and brothers. They might feel ashamed now, but that makes them put more importance on their old bonds." Aizawa added.

"This commotion... And Chisaki and the top brass haven't shown themselves yet. They're probably underground getting ready to hide or flee right now."

"That's not loyalty!" Eijiro shouted, irked. "Forcing their henchmen to take responsibility and running away themselves isn't manly!"

"Yeah!" Fatgum agreed.

Yuko ran beside the red head, finally deciding to speak, "but what Chisaki is looking for, isn't loyalty. It's power." She bluntly pointed out.

They all skidded to a stop as Nighteye stopped in front of a opening in the wall, a flower pot resting there for decoration.

"It's here. There's a device here to open a hidden passage. By holding down these wooden floorboards in a specific order..." He removed the pot, beginning to press on the boards, "...it'll open."

The girl felt a sudden chill, her hand hovering over her dagger. "Be careful of Quirks we haven't seen yet."

She gasped as three men emerged from the tunnel, Centipeder quickly acting, calling out to his partner, Bubble Girl. The two quickly took down the men, Yuko staring in awe of the two.

"I'll make them stay here and not follow us." Bubble Girl assured, "please go on ahead."

"Let's go!" Nighteye ordered.

"I'll join you again soon!" The female called to them as they all quickly made their way down into the tunnels.

"We're almost there! Hurry!" They came to a stop as they turned a corner, a wall blocking their way.

"It's a dead end...!" Yuko rolled her eyes as they called out the obvious. "You sure you're not mistaken?"

"Explain yourself, Nighteye!" Rock Lock demanded.

"I'll go look." Mirio offered, removing his helmet.

Eijiro looked at the third year, "Lemillion, wait! Your clothes might--" The red head was cut off by Tamaki

"It's all right. Mirio's costume is made of a special fiber made from his own hair. It's made so it becomes permeable when he activates his Quirk." The blue-black haired male explained.

"It's just been blocked off by a wall." Mirio called to them, after looking through the wall. "But it's a pretty thick wall."

"With Chisaki's ability to break down and restore things, even this is possible?" Rock Lock whispered in surprise.

"A cheap trick..." Fatgum huffed.

"It's like he's telling us he'll be in trouble if we go this way." Izuku spoke up, Eijiro and Yuko agreeing.

The dragon rider looked at the boy's with a nod, taking a few steps back, "let's show him something like this won't stop us."

Eijiro's fist hardened, as the signature green lightning surrounded Izuku. The two launched at the wall, the greenette with a kick and the red head with a hardened punch, bringing the wall down. Yuko huffed with a grin, looking at the two, seeming proud.

"You guys aren't too bad..." Rock Lock mumbled.

"They beat me to the punch." Fatgum nodded.

"Let's keep going." Mirio ordered, the group quick to follow the students as they began to run, yet again.

Yuko's crimson colored eyes widened in size as the floor began to move under them, the walls following. The girl's movement grew wobbly as she tried to keep upright, grabbing onto Izuku's arm as she tripped forward.

"What the..?" She mumbled, looking around in confusion, caught off guard by the sudden movement.

"The path is moving..?!" Eijiro shouted, as he too tried to keep upright.

"It's changing!" Izuku added as the girl removed her grip on his forearm.

"It's not Chisaki! It's different..." The Chief of police pointed out, "the only one it could be...is the director, Irinaka!" Yuko huffed as she outstretched her arms, trying to keep her balance.

"Irinaka's Quirk, Mimic, lets him go into objects and control them freely from within! He's gone into the concrete that makes up the underground, and it's turned into a living maze!" Yuko looked back at the information.

"But it's on too big of a scale! He shouldn't be able to enter and control objects bigger than a fridge!" Yuko's eyes widened, coming to a conclusion.

"A boosting drug!" She yelled back at them, Fatgum nodding in agreement with the girl.

"If he gets a big enough boost, it's not impossible, huh?" Fatgum added, "I was bein' careful about what he'd turn into, but I didn't think he'd turn into the underground. This has got to be hard on him physically."

Yuko began to trip over her feet, her hand moving to the flimsy wall, hoping for some type of support, before she once again held her arms out for balance.

"Eraser, you can't get rid of it?" Fatgum questioned the underground hero as they ended up back-to-back.

"Not if I can't see the main body..." He answered.

Yuko looked back as Tamaki began to mutter, the girl frowning at his negative outlook on the situation.

"Tamaki!" Mirio stopped the male's muttering, placing a hand on his shoulder despite the moving floor.

"That's not going to happen. You're the Suneater!" The blond reminded.

"Besides, this is just a stopgap! No matter how much they try to warp the path, as long as we know the direction of our goal, I can get there!" The blond ran forward, surprisingly keeping upright in the process as Nighteye and Izuku called to him.

"Time is of the essence! Those guys know this, too. That's why they're stalling for time. I'm going on ahead!" He called back to them, not bothering a glance as he pushed past the unbalanced flooring, disappearing through the walls, out of sight.

Yuko gasped as the flooring was suddenly opened below them. She grunted as her back hit hard flooring, she pushing herself into a sitting position, looking up at the closed ceiling above.

"A hall?" Izuku questioned.

"We're getting further and further away from our goal! It looks like they've got us good!" Rock Lock stressed.

The black haired dragon rider slowly stood, looking around with caution. Her head whipping to look back as someone approached from behind, repeating hey.

"Some government authorities have fallen from the sky. Strange things happen, huh?" A male with yellow hair and a bird-beak-shaped mask looked at them with wide, crazy eyes.

Two other males stood with him, a bald male, who was much muscular then the yellow haired one, with a white mask, stood beside him. Another stood behind him, he with a mask over his head, it tied around his neck with a rope, there was two holes for his eyes, and there was a stitch along the bag, that seemed to represent a mouth.

"It looks like they're ready for a fight. It's about time we showed them the strength of a pro--" Fatgum began, cracking his knuckles, only to get cut off by Tamaki holding a hand in front of him.

Yuko blinked in surprise, staring at the older male, who she looked up to, despite his serious anxiety.

"Save the strength of pros for the goal." The male ordered, Yuko eye's widening at the strength in his voice. She could hear the determination.

"For the ones stalling for time...I'll be enough by myself." He declared.

"What are you saying? Let's work together!" Eijiro tried to reason.

"Yeah, work together." The yellow haired male chuckled, showing the blade he held, "I'll kill all of you."

"It's Setsuno! We can't use our guns against him! Heroes, it's up to you!" The Chief of police informed.

"You figured it out, huh? Oh, well." Setsuno shrugged, flying at them, his hand outstretched, and his blade at the ready.

"It just makes it easier to go wild!"

"We won't let you!" Aizawa grabbed his scarf, his hair flying up, "throw away your sword." The hero ordered.

Setsuno stopped as he looked down at his hand, "I can't use it."

His bald companion drew a gun, pointing it at the underground hero. Yuko's eyes narrowed, huffing under her mask as she took a step closer to her homeroom teacher, a pair of daggers in each of her hands.

"He erased his Quirk?" The Hassaikai muffled through his mask, "an inferior version of Eri's Quirk. I've heard a hero like that exists. But it doesn't matter. What we should be doing is blocking them. That's all."

"Swords and bullets will just sink into my body." Fatgum informed, "it'll be better for you to give up now."

"Threats like that just make you sound like you fear for your life." Setsuno called back to him, unfazed by Fatgum's supposed threat.

The police drew their weapons, pointing it at the three, "since Eraser's erasing your Quirk, we can use our weapons! Resign yourselves and surrender!"

Yuko gasped as octopus tentacles wrapped around the three, Tamaki naming them as he goes.

"Larceny, Toya Setsuno."

"Crystallize, Yu Hojo."

"Food, Soramitsu Tabe."

"I've looked over the documents with their info!" Tamaki shouted, slamming the three into the wall, "I'll take these guys on." He held up another tentacle, which held the their weapons belonging to the Hassaikai members.

"At Fat Agency, we eat tons of takoyaki, so I'm really good at using octopus. Since I was shot before, I'm more alert to things like this." The tentacle replaced itself with the claws of a crab, smashing the weapons.

"But Suneater!" Eijiro protested.

"It won't do any good for us to all fight against them." The male once again interrupted, "with so many pro heroes stopped here, we're playing right into their hands. We should save the pros' Quirks, including Eraser's, for later! We should save the power to get through the wriggling underground, too! And the police officers and their guns! Fat Gum!"

Yuko looked up at BMI Hero, "if it's me, I can completely shut down all three of them." The dragon rider stared at the hero, waiting for his call.

"Let's go!" Fat Gum ordered, Yuko quick to follow him, glancing back at Tamaki.

Setsuno went to stop them, despite the tentacle wrapped around him. Aizawa turned to him, erasing his Quirk. The underground hero ran at them, snapping Tabe's head to the side, and knocking him out.

"Amajiki, I used my Quirk on the three of them. Bind them up before the effect wears off." Aizawa informed, before they all quickly followed Fat and Yuko, leaving the third year on his own.

"Everyone!" Tamaki called before they left, slamming the villains into the walk, once more.

"Please take care of Mirio! He's definitely going to try too hard, so please help him." They pushed through the doors, entering the tunnels once again.

"Fat! You're going to leave him alone like that? What are you thinking?" Eijiro questioned the hero in worry.

"He's from your agency, so I left that decision to you, but frankly, isn't he in trouble?" Rock Lock, too, decided to question.

"He's stronger than anyone here." Fat Gum declared, Yuko running a few paces behind as she nodded.

"But he was weak emotionally. He crushed himself with pressure to do things perfectly. He climbed up to become part of U.A's Big Three under those conditions. Someone like that declared that he could completely shut them down! So...all I can do is leave it to him!"
