Chapter Eighteen: The Seige begins... Or so it seems

The next day Xero went to Nezu's office and had the top heroes there with him. "Ok so we have a problem," said Xero. "What kind of problem do you mean Xero?" asked Nezu. "Well the world's No.1 Villain is after me and I need help," said Xero. "Wait, seriously?" asked the heroes and Nezu while sweating heavily. "Yes, and if you don't want to help then I don't blame you," said Xero. "We'll help but as soon as it gets to be too dangerous we'll have to bail because we can't let the hero society fall because of our deaths," said Nezu and the other heroes. "Thank you very much but i also have to tell you something that might change all of your minds," said Xero. "What would that be?" asked Nezu. "Well before you overreact he agreed to help in defeating her," said Xero. "Who is this he and this she you're talking about?" asked Nezu. "Well this guy that I'm talking about is All for One. And this girl that I'm talking about is Saiita, also known as the No.1 villain of the world…" said Xero. Everyone was broken after trying to contemplate what they just heard. "Okay now-... WAIT WHAT???!!!," said Nezu. "Yeah, It's crazy," said Xero. Most of the Heroes bailed knowing that they'd be working with a villain. The only ones that stayed were All Might, Eraserhead, Best Jeanist, and Endeavor. "We'll help you," said All Might. "Thank you all for this," said Xero. "But like we said before, If we end up too close to death we will have to bail. If we were to stay in the case of near death then hero society would for sure fall and there would be nobody to stop the villains," said Nezu. "I understand, I know I can take her on my own but I don't know the full extent of her power." said Xero. "Ok so when will she be arriving approximately?" asked Nezu. "In about three to four days," said Xero. "I see…" said Nezu. "My plan is that I go in with All for One first and if he tries anything that I find threatening then I'll signal you all to join the fight," said Xero. "Ok, understood," said Nezu and the other four heroes. "Great, and also if I feel the situation is getting out of hand and you don't see me, All for One or Saiita then you have my absolute full permission to leave." said Xero. "Ok, we'll do our absolute best to assist you!" said All Might. "Okay. Thanks," said Xero. The next day Xero met up with All for One. "All for One…" said Xero. "Ah, Xero you're here.." said All for One. "Yes, and I have come to meet you here today because I just want to let you know something," said Xero. "And what would that be?" asked All for One. Xero looks at All for One with a death glare. "If you even try to double cross me or attack my allies I will not hesitate to wipe you from existence…" said Xero coldly. All for One almost shits himself hearing these words and seeing the look on Xero's face. "Do I make myself clear?" asked Xero. "C-crystal," said All for One, trying not to show fear in any way. "Good… I'll be seeing you…" said Xero. All for One stood there, speechless. Not knowing what to do, All for One went back to his base. When Xero returned to the school he told Nezu that All for One wouldn't try anything and that he saw that it happened personally. Later on Xero and Nezu spoke in private to see that the other students that will not be involved are moved to another location temporarily so as to not have them injured during the fight. Xero recently started practicing training with clones so if he had to multitask he wouldn't get tied up in what he was doing at the moment. Xero also practiced his timing and his ranged combat so he could have the upperhand. Time skip 3½ days. Suddenly the ground starts to rumble towards the coastline. Bystanders then see a girl walk out from the water making their way to the city. There's a sudden gust of wind and she disappears. In the middle of the city the winds get really high for a second then die down. Everyone looks in the direction of where the wind came from. She stops on a sidewalk in front of the Endeavor Agency. She walks in and goes to the front desk and asks for Endeavor. "I need to see Endeavor immediately please," said Saiita. "Do you have an appointment?" asked the receptionist. "No, but it's urgent," said Saiita. "Ok well I'll call him down here right now," said the receptionist. "Thank you," said Saiita. Endeavor makes his way down and walks over to a waiting Saiita. "Are you the one who asked for me?" asked Endeavor. "Yes," said Saiita. "What is your name?" asked Endeavor. "Oh, yes I almost forgot. Please don't over react. I'm here to warn someone named Xero about All for One." said Saiita. "I'll see that he gets the message. But you still haven't answered my question," said Endeavor. "Sorry, I just wanted you to hear me out before attacking me." said Saiita. "What do you mean?" asked Endeavor. "Well, I'm Saiita The World's No.1 Villain." said Saiita. "Oh, so wait, you're not a threat?" asked Endeavor. "No, I'm not a threat," said Saiita. "Hm, well would you mind coming with me to prove it?" asked Endeavor. "Sure, I don't see the problem," said Saiita. "Oh, I honestly thought that you would decline," said Endeavor. "Nope," said Saiita. They both left for the police station. Saiito took a lie detector test and passed. She walks up to the doors of U.A and walks in. She doesn't get attacked because she has a visitor pass from Endeavor. She then makes her way inside to Nezu's office.
