Izuku was running towards the train station. A villain had recently appeared there, and had attracted several heroes. Of course, as soon as he had heard about the incident, he began to make his own way down to the station. Crossing the street quickly, he continued his run. This was the perfect chance to observe the heroes at work, and there was no way he would miss it!

Pushing through the crowd to the front, Izuku looked up at the incident in progress, watching as the hero Kamui Woods began his counter-attack. "Oh, this is gonna be good! Its Kamui Woods! He may be new, but he's making a big name for himself!" The stranger next to him turned towards Izuku and laughed. "One look at that dopey grin and I know what you are, A fanboy!" "Uh, sort of…" responded Izuku with a small laugh. Turning back to the fight, Izuku pointed up in excitement "There, His special move! The Pre-emptive, Binding, Lacquer chain prison!" Woods reached out his hand to bind the villain in a cage of wood.

And that was the moment the side of the villain's head exploded into a shower of blood and flesh.

Izuku looked up in shock as the villain's body fell to the ground, caught by an equally shocked Death Arms. What kind of person would do this? Even if the guy was a villain, he didn''t deserve this. More importantly, who did this? None of the heroes were responsible, but it must have been someone's doing. The question is, who?

Matsuo Yasushi, Accountant at the Mitsubishi Motor company and father of two, looked up from his scope to observe the results of his actions. Watching the villain fall to the ground brought a smile to his face. Quick as he could, Yasushi disassembled his rifle, and packed it away into his briefcase. The trains were out, and he was late as it was. Guess he would need to walk.

Yasushi turned to look at the television in the break room. The words *Villain takes child hostage! Heroes helpless* flashed across the bottom of the screen. Sighing, he picked up his phone and dialed a number he was quite familiar with.

"Hey, sweetheart. Yes, I'm calling about the Shopping street problem. Wait, what? What do you mean you can't? Yes, I know it's your day off, but i'm nowhere near the scene. I just need you to… Alright great, thank you. Don't worry, i'll make it up to you."

Laughing softly, Yasushi leaned back in his chair and waited for the show to begin.

Izuku was panicking. So far his "Charge the villain and save Bakugou" plan had gone off about as well as expected. He had reached Bakugou just fine, but had been unable to free him from the villain. He was just about to give up when he saw someone step out of the crowd and begin to walk forward. They were wearing a white lab coat and… was that a gas mask? It looked like Death Arms was about to hold them back, when they pulled something out of their coat, and threw it.

Matsuo Rin, Doctor of Toxicology and mother of two, smiled under her mask as her latest experiment landed by the villain, releasing a cloud of thick white gas. The two kids near the slimeball were an unexpected variable, but she was confident in her ability to get them out of the way as she… dealt with the green thing that was tearing up downtown. As she walked, she withdrew a second canister, and prepared to meet the villain head on. This would be a most fascinating experiment.

Izuku lay face down in the street, choking on whatever it was that women had thrown at them. Next to him the villain was also succumbing, the fluid of his body slowly melting off the limp form of Bakugo. Not that he noticed. He had no energy for anything but coughing up his lungs, and learning the footsteps behind him. Suddenly, a mask was pressed against his face, and he found himself slowly able to breath again. Looking up at his savior, he saw the masked face from earlier. Before he could ask them anything or even thank them, they pulled Bakugou from the ground and placed him in Izuku's arms. "Take him and get back to the crowd" They (She… it sounded like a she) instructed him as she moved closer to the downed villain. "Who are you? What is this stuff?" Izucu called after her. He got no response.

Rin walked closer to the pile of goo on the ground, slowly trying to rise from his spot on the ground. "Hm, I bet you thought you were invincible, with all those heroes that couldn't stop you, huh?" she asked him. "But you overlooked one vital weakness, air. As difficult as you might be to fight, even you need to breathe, so take a deep breath… and choke on it."

The attack near Tatooine Station ended with the hostage rescued successfully, but not in a way anyone could have predicted. As the gas cleared and Izuku Midoriya gave his testamony to both the Police and the heros, a search for the mysterious woman was launched. After a sweep of the area, however, no one who met the description of the witnesses was found. The search was dropped, but the face (or at least mask) of the mysterious poisoner was inevitably spread across the internet. As people began to speak in earnest about this mysterious stranger, and the recent murders in Musutafu, no one batted an eye at the mother returning to her family.

Matsuo Rin opened the door to her apartment to find her husband on the couch, watching news coverage of their actions at the shopping street. "Getting quite famous, aren't we?" said Yasushi. "Unfortunately so" replied Rin. "We won't be able to hide our work for much longer." Yasushi motioned for his wife to join him. "Well, what now?" She asked. "First, we need to make sure no one knows who you are." replied Yasushi. "Then we need to start getting closer to the heroes. If we can't work in secret maybe the kids can.. They're in position already, after all." Rin looked over to where Yasushi was sitting. "No I mean right now. You did say you were going to make missing my day off worth it, right?" "Oh, of course" came the expected reply. "I've put in a reservation at that restaurant you like already. we still have the whole knight ahead of us, after all, and we deserve to relax after the day we've had." Rin smiled. They could deal with all the problems they had caused later. Yasushi was right, after the day they'd had, they deserved to treat themselves.
