Mina waved the criminals through. "Alright, everyone! Please stay in a single file line! The more you cooperate, the faster you can be put in your cells!" Momo looked at Mina. "Pinky, do you have to mock the prisoners?" Mina thought for a minute before smiling at Momo. "Yep." Nejire walked up to the two students. "I'm proud of you guys. Your very first raid went incredibly well." Momo smiled. "Thanks, Guiding Light, but it was just a small gang." Nejire waved it off. "It's still something. I know Ryukyu will be very proud of you both." Mina smiled. "I took out more bad guys." Momo did a quick count on her fingers. "...No you didn't. Guiding Light did." The sidekick smiled. "Yep." Mina did her own count. "...No, because I helped with half of them." Momo shook her head. "Assists don't count." "Yes, they do!" The three argued all the way back to the Ryukyu Agency. They burst into the pro's office to have her settle the argument, but all fell silent when she raised her hand up. She was on the phone. "Yes. Yes. Ok. Yea, we'll be there, Nighteye. See you tomorrow." Ryukyu hung up. "Pack your bags girls. We leave for Los Angeles tomorrow." Momo perked up. "We're going to be helping the Nighteye Agency?" "Yes. He's planning something big and he needs our help. Nobody can know about this." The girls nodded and began preparing to head to Los Angeles.
Kirishima, Tamaki, and Fatgum all entered the Nighteye Agency. Kirishima immediately hugged his friends. "Hey, guys! Long time no see!" Jason playfully punched him. "Saw your little fight on the news. Nice work." He looked stunned. "Wait, that was on the news?!" Chris looked up at the ceiling. "Oh my god, he's still slow." Kirishima pointed at Chris. "Don't you start!" They all shared a laugh as they went to wait in the lounge.
Chris, Jason, Momo, Kirishima, and Mina all sat together at the meeting table, along with 10 pro heroes and their sidekicks. There were also several police officers present too. Nighteye sat at the head of the table. "Thank you all for coming. The time to end the Cosa Nostra has come." The room fell silent. Nighteye turned on a projector, showing an image of Overhaul. "This is Overhaul: the current leader of the Cosa Nostra. It's believed his organization has been creating and distributing darts that can temporarily deactivate quirks. They have been improving in quality over time. However, an inside source has informed us that he's currently in the works of creating a version that permanently erases quirks. Unfortunately, we lost contact with him only a few hours after he informed us." Ryukyu swore. "Which means they're onto us." Nighteye nodded. "However, thanks to Impact and Lemillion, we now have a good idea of what the source of the darts are." The picture changed to a blurry shot of the alleyway confrontation. "The young girl, named Eri, is presumably Overhaul's daughter. The current theory is that she has a quirk that allows Overhaul to create the darts. If that's the case, then her rescue is our top priority." The heroes nodded. The stakes were painfully clear: if they can't rescue Eri and capture Overhaul, the Cosa Nostra wins.
The five students sat in the lounge. Momo looked up. "...Too bad Shoto isn't here…" Jason sighed. "If the Endeavor Agency was involved, this entire operation might go public and ruin whatever element of surprise we have left." Aizawa walked up to the table. "Hey, guys." Chris stood up respectfully. "Mr. Aizawa!" The teacher raised his hand in silence. "We're working. Call me Eraser Head." Chris nodded. "...Right. Sorry, Eraser Head." Jason looked up at their former teacher. "This is our first big raid. Any advice?" Aizawa thought for a second before looking back at his former students. "Keep your head on a swivel, stay close to your mentors, and remember your training." He gave a small smirk. "If you all fight like you did in the USJ, you'll be fine." He walked off. The five friends smiled. They were more confident now. They would beat the Cosa Nostra at any cost.
The next day, there were a hundred people gathered outside the alleged Cosa Nostra headquarters. A police officer was reading the search warrant out loud. Chris looked up at Nighteye. "If we know the Cosa Nostra are inside, why can't we just go in?" The hero looked down at the student. "A few years ago, heroes and police officers kept going into homes that had suspects inside. However, in some of the cases, there was no investigation or logical reasoning for doing so, resulting in a lot of false arrests and avoidable collateral damage. Now a warrant is needed to search any property." Momo took a deep breath. "This is it." Ryukyu smiled and put a hand on Momo's shoulder. "Calm yourself. There's a small army here. I'm sure they're already trying to run." Before the officer could finish reading the warrant, a giant of a man burst out of the entrance, tearing down the entirety of the front wall. Everyone was speechless. The man looked down at the heroes and cops in disgust. "Get off our lawn." A shadow loomed over him. Ryukyu had activated her quirk: she had taken the form of a five-story tall dragon. She smacked the man away from the main building. "Go! I got him!" Momo, Mina, and Nejire activated their quirks to help Ryukyu. Jason was shocked to see Chris rush in first. Then everyone else followed suit. The raid had begun.
