It was time for the I-Island which Izuku went using a ticket she afforded for herself by using her kingdom's treasury. She felt guilty doing it but Moon insisted Izuku go to such an event besides Moon said the kingdom owes Izuku one for all she done for it. So, she went and had a grand old time first she went to the pavilion show casing several inventions where she runs into Ochaco, Momo and Kyoka. They decide to have some drinks (tea) together. Where they found Denki and Minoro working as staff members, that's when Tenya ran at top speed to remind them to represent U.A as good workers. That's when they hear an explosion thinking it's an emergency, they go towards the blast noise only to see it's Katsuki at one of the attractions, winning first place. Eijiro then explains that first place at the U.A festival got Katsuki two free tickets. Izuku tries the attraction next and uses Strawberry Blast to hit all the targets coming in second "How you like me now?" Katsuki said bragging to Izuku causing Ochaco to try the event next out of jealousy, she used Zero Gravity on the rocks nearby and threw them at the targets, winning her third much to Katsuki's relief (to his own surprise). Only to get knocked out of first by Shoto using his ice much to Katsuki's anger. Shoto reveals he's there to represent Endeavor, Tenya runs over at top speed again and yells "We can't misrepresent U.A."
Later that night while All Might is making a speech the gang (Izuku, Momo, Ochaco, Denki, Minoro, Tenya, Shoto and Kyoka) meet up "You look good Ochaco." Izuku said, only for Ochaco to say while blushing "Yah so do you Izuku."
Izuku was wearing strapless light purple dress underneath she was wearing dark purple long sleeve and matching stockings with light purple high heels and matching gloves
"Thanks." Izuku said and couldn't help but blush at the complement but it quickly turned to sadness "You missing him, aren't you?" Ochaco said with the him being Katsuki, Izuku nodded her head in agreement "We can wait here for them if you want, no one would blame you." Ochaco said "No, I do not want to intrude on your guy's good time. Let's go." Elsewhere "Do you think this is good enough for her?" Katsuki said with what he was referring to what he was wearing, only for Eijiro to say "For the millionth time, yes. Now let's go." Back with the gang there were about to leave for the gala when the alarms goes off across the entire island, the security system threatens everyone with a curfew. The system also locks the central tower from the outside. All Might notices Izuku flashing a light at him from the third floor. Kyoka uses her quirk to listen in on All Might who tells them what's happing. That's when a person they never meet showed up "I'm Melissa, don't worry I know All Might. He's a friend of my father David Sheild." Melissa sayed "Whoa as in the David Sheild, All Might's first partner. David Sheild, that David Sheild! Wait, how do we know we can trust you? Not From The Roof, Tell The Truth." Izuku said then blasted Melissa "I'm telling you the truth; my dad really is David Sheild." Melissa said "Yep, she's telling the truth. I just used a truth telling spell on her." Izuku said, "We should escape since we can't legally fight villains." Tenya said, only for Melissa to say "On this island you approved to use your quirks and you know I'm telling the truth since I'm still under that truth spell." Shoto and Kyoka say at the same time "We should help, jinx." Only for Minoru to say "Haven't you learned anything from the U.S.J incident, Izuku?" "We can save people without fighting." Izuku said, only for Melissa to say "I believe in him." "How you just meet him." Kyoka said, only for Melissa to say "I watched the U.A sports festival, so I know what I'm talking about. We can reset the security from the top floor of the tower." Everyone decides to work together to disable the security system so All Might can save the day. "Now quick what's your quirk." Izuku said, only for Melissa to say "Actully I'm quirkless but I should still go on with you guys since I'm the only one here who knows how to disable the security system." "That's true, you guys." Izuku said, only for everyone else to agree with her "Great, now that's settled let's go." They told All Might what they were doing who disapproved but ultimately agreed to it. They scale fifty floors until they run into a shutter cutting them off on the 80th floor then Minoru makes the mistake of opening the door to the main section of the floor. This notifies the villain, Wolfram who send his men to neutralize them. Shutter's close the students on both sides of the hallway and Shoto uses his ice to keep one of the doors open, long enough for Tenya to open a path to the plant factory. Kyoka then notifies everyone that the elevator on the floor they're on is moving so Izuku hits them with an invisibility spell then when the door opens, they go in for the attack only for it to be Katsuki and Eijiro. 'Wow, he's so handsome. No don't be like that, don't be the type of person who judges people on looks. Be the type to judge on personality and his is great' Izuku thought "I know you guys are here, I can hear you. Drop the invisibility spell, Izuku." Katsuki said, Izuku did just that only for Katsuki to think 'Wow, she beautiful. No don't think that, it's not about looks, it's about personality and hers is great.' "We got lost." Eijiro said, only for the villains that Wolfram sent to arrive and get rough. Shoto acts quickly and creates an ice shield to protect Eijiro from the goon's (named Nobu) quirk while also creating an ice piler to rise the others (with the exception of Katsuki and Eijiro) to the next floor "We're going to reset the security system, so All Might can save the day." Shoto says before they (Katsuki, Shoto and Eijiro) engage in battle. Izuku's group don't see a way forward but they notice a small door on a nearby roof panel. Melissa explains it leads to the maintenance room but can only be accessed from the inside. Momo creates a small bomb to open the door and tells everyone they can still use it to access the outside wall. The group volunteers Minoru for the job since he's the only one who could easily climb and fit in it, and Denki encourages him "There's going to be a harem waiting at the end of this incident for you." Minoru uses his Quirk to scale the outside of the tower and completes his task by opening the way for his friends. In the control room, the villains are irritated by the student's resistance. They demand the invaders in the field to deal with the students. The villains fighting Shoto and Katsuki prove to have strong Quirks. Daigo has a beast shifting Quirk while Nobu's Quirk allows him to hollow out space. Katsuki defeats Daigo with his Howitzer Impact move. He gets his sweat on Nobu, giving Shoto the opening to detonate it with his fire. After defeating the villains, Shoto and Katsuki check up on Eijiro. He's fine, just stuck in place by his own Quirk. They're interrupted when a mass of security bots flood the plant factory. Wolfram orders his subordinates in the control room to use the security bots to apprehend the students. Izuku's group passes the 100th floor and Denki notes how the shutters have opened for them. Ochaco deduces that the villains are trying to lead them somewhere. They reach the 130th floor and are greeted by dozens of security bots. Momo prepares a sheet of isolation for the group and they execute Plan A. Tenya uses his speed to throw Denki at the bots where the electric hero uses Indiscriminate Shock 1.3 Million Volts. The robots are able to defend against his Quirk so Denki turns up the voltage to two million. His power quickly fades out and Denki shorts out his brain. Tenya holds off the Security Bots, then says "Switch to Plan B." Momo creates smoke bombs that interfere with the robot's systems. Everyone throws them at the robots while Minoru uses his balls to trap them. Izuku and Tenya use their strength to break through the blockade. Izuku pushes the bots back using "Raspberry Roast." Wolfram's subordinates notify him that the students got away and he deduces one of them has a sensory Quirk. The students make it to the server room on the 30th floor where they are ambushed by even more security drones. Melissa warns everyone they can't afford to damage the server room by fighting. Tenya and Momo offer to hold off the drones while Izuku takes Melissa on another route. Ochaco joins them and leaves everyone else to fight. Tenya takes on the bots using Recipro Burst while Momo creates a cannon that fires adhesive material. Izuku, Ochaco, and Melissa continue ahead as their friends fight. The bots manage to outlast Tenya's time limit and Momo and Minoru's bodies have reached their limit as well. The robots use restraining bonds to capture the kids. Izuku's trio reaches the wind power generation system where they hope to avoid getting ambushed again. Melissa asks Ochaco "Use your Quirk to float Izuku and me toward the emergency exit at the top of the tower." Shoto sends Izuku and Melissa to the top of the tower. Ochaco lifts Izuku and Melissa toward the exit, but this leaves her exposed to another robot ambush. Melissa tells Ochaco to release her Quirk but she refuses. Just before the robots get to her, Katsuki makes an explosive entrance and saves her. Shoto and Eijiro join the battle and repel the bots using their Quirks. Wind threatens to carry Izuku and Melissa away but Shoto acts quickly. Katsuki moves one of the wind turbines toward Izuku, and Shoto uses his flames to push hot wind in their direction, setting them back on course. Izuku takes a moment to thank Shoto for using his fire and then uses "Super Strength" on herself to break her way into the top floor of the tower. Ochaco releases her Quirk once they're inside and Wolfram learns of their advancement. He orders Swordkil to deal with the intrusion. All Might struggles to maintain his form but he continues to believe in his students. Izuku and Melissa recover from the fall as neither of them are injured. Swordkil suddenly attacks them both and Izuku grabs Melissa and rolls out of danger. Swordkil keeps up his attack using his Sword Hands Quirk but Izuku parries using the wand. Swordkil nearly gets the better of Izuku but Melissa helps him. The villain knocks Melissa aside but this gives Izuku an opening to land a Strawberry Blast to defeat Swordkil. Izuku makes sure Melissa is okay before they continue their mission. Izuku clashes with Swordkil, She fights her way through more of Wolfram's henchmen until she and Melissa finally reach the top floor of the tower. Together they find David Shield inside some sort of vault. Inside the storage room, David manages to unlock a special block and sends Sam (his assistant) to retrieve a special item. David swears to never let this device into the wrong hands and Sam replies that everything is according to plan. Melissa overhears the men talking about working with the villains. Melissa makes her father admit the truth, as he reveals he created a Quirk Amplification Device, but it was taken away and locked up by their sponsors. It was originally Sam's idea to hire fake villains to steal the research back for them. Izuku and Melissa are both horrified by this revelation and the latter demands to know why. David admits that he was doing this for All Might because his Quirk is disappearing. Izuku feels guilty knowing the truth of why All Might lost his power and now David is acting desperately on that. Angry, Melissa tells David that she and her friends risked their lives to save everyone, showing off a scar from Swordkil's attack on her arm. Confused, David says the villains were supposed to be fake. Wolfram makes a dramatic entrance and reveals that the only act was the villains pretending to be fake. Izuku tries to attack but Wolfram quickly restrains him using his Metal Manipulation Quirk. Sam betrays David and brings the device to Wolfram. He claims that David turned his back on him when they never got paid for working so hard. Wolfram shoots Sam in the arm and acts like they never had an agreement. He shoots again but David jumps in the way of the bullet. Wolfram steps on David's injured body and tells him to "Stop playing hero. What you did was a crime and that won't disappear with one good act." Wolfram claims David can't go on being a scientist anymore and knocks him out. He plans on using David to mass-produce the Quirk Amplification Device. Melissa pleads with the villains to return her father. Her cries fall on deaf ears and Wolfram threatens to eliminate her. Izuku breaks free from his bonds and attacks, only to be blocked by Wolfram's Quirk. Izuku tells Melissa that "I'll save David but you needs to be the one to save everyone else." Melissa flees and the Hacker tries to follow. Izuku refuses to allow him to pass, forcing him to come to blows with Wolfram. Together, Melissa and Izuku manage to save everyone by disabling the security system. All of the drones return to normal mode and I-Island is set free from the grasp of the villains. Wolfram prepares to escape with David on a helicopter and Izuku pursues them. Melissa calls All Might to update him on the stakes. All Might promises to rescue Izuku and David. "Give the Professor back!". Izuku screams, David asks that the villains kill him but Wolfram has other plans in mind. Izuku catches up to them on the roof and Wolfram asks if she's come to rescue a criminal. Izuku rushes toward his foes and cries out that she's going to rescue the professor. Izuku manages to evade most of Wolfram's attacks as he shouts "It's a hero's duty to rescue those in need." Wolfram turns his gun to David, forcing Izuku to stop, and then slams him with a metal pillar. He barrages Izuku with similar attacks and gets on the helicopter with David aboard. Izuku refuses to let the professor go and uses Light Wings to go after him. She grabs on to the helicopter and tells the professor that "Melissa is waiting for you." Wolfram tries to shoot Deku but the bullet is sent off course by a swift tackle from David. Izuku crashes into the helipad below and laments letting the villains escape. All Might's voice reaches through the sky and reminds Izuku to smile in situations like these. The Symbol of Peace leaps high above the helicopter and restores faith in everyone with his signature motto. "Everything is okay because I am here!". All Might says as he returns to save the day and soars through the helicopter, rescuing David and sending the villains to their fiery demise all in one motion. David tries to apologize to All Might but Wolfram abruptly appears from the smoldering remains of the crashed helicopter. He attacks them both with a metal pillar and traps David in a metal casing. Wolfram is using David's Quirk Amplification Device to boost his Quirk exponentially. The No. 1 Hero tries to silence the villain but Wolfram proves far more powerful than before. Wolfram uses his enhanced powers to transform the tower's roof into a scrap metal hell. Wolfram nearly crushes All Might under the weight of a steel barrage. Shoto and Katsuki prove a hero is never alone and come to his rescue. The other students join the fray, with Tenya and Eijiro taking on the metal pillars as well. Motivated by his student's passion, All Might goes beyond his limits and uses his awesome power to break through Wolfram's iron defenses. All For One secretly aided Wolfram's invasion to spite All Might. Just when it seems like the No. 1 Hero is gaining the upper hand, Wolfram traps him with metal wires and tries to crush his throat with a surprise Muscle Augmentation Quirk. All Might can't believe Wolfram has even more power and deduces that his most evil foe, All For One, must be behind this. When Wolfram was planning the invasion, All For One contacted him offering to help. All For One gave Wolfram this power and information on All Might because he wanted to help twist All Might's best friend to the darkness. All Might's smile fades from the shock of finding out his arch-nemesis has orchestrated the incident. Wolfram crushes All Might under a torrent of scrap metal. Izuku's instincts kick in and he breaks the iron prison apart using an Ice Blast in time to save All Might. All Might scolds Izuku "You were being reckless with your quirk." Only for Izuku to argue "A hero must act when people are in trouble." All Might's smile returns and he thanks his young student. He asks that Izuku aid him in this final battle. Izuku arms her wand and Izuku and All Might, rushing pass an endless iron assault from their foe. Melissa watches as Izuku mirrors All Might and is moved to tears by their teamwork. Wolfram's last-ditch effort is forming his metal into a massive iron cube large enough to crush the tower. All Might and Deku go beyond their limits and break through the cube by using their respective powers (All Might with a Detroit Smash and Izuku with an Ice Blast)! David and Melissa watch as the U.A. students cheer on their heroes to victory. All Might and Izuku chant the time long motto of U.A., "Plus Ultra", as they finish the villain off with their respective abilities (All Might with One For All and Izuku with Blueberry Bomb). At last, the heroes are victorious and the scrap metal hell disintegrates into dust, along with the Quirk Amplification Device and the Full Gauntlet. As he regains consciousness, David sees the triumphant pose of Izuku, and sees a young All Might within him. Melissa checks on Izuku and All Might on David. David thanks All Might for saving him but All Might bestows the credit on their successors. They are the two heroes who saved the day. Reuniting, Melissa appreciates everything Izuku has done, while reminds her that her actions helped save everyone on this day. All Might tells David that Melissa explained the details of what happened. David admits that he was so afraid the Symbol of Peace would fade away and lead to the end of peace. David realizes now that he was just trying to hang on to the past, and knows that Izuku and Melissa will protect the future and ensure peace to everyone. All Might says "Izuku you aren't ready yet but you possesses the potential to be the greatest hero". David says he can feel the same light in Izuku that comes from All Might, the light of a hero.
