Dabi POV

10 days ago was new years day. Being villains, they didn't feel the need to celebrate nor did they have anyone to celebrate it with. Instead, they used this opportunity to plan their next course of action. Seeing how both Dabi and the Warp failed their missions twice angered Shigaraki to the core. He has had enough of those children messing up his plan time and time again. Shigaraki wasn't going to take any chances. This time, they were going to attack as a whole league, in other words, a full out attack. The aim of this mission was to get rid of Midoriya Izuku, Bakugou Katsuki and Todoroki Shouto. If they got rid of any other students and pro heroes, it would be a bonus.

So here they were, in Kyoto. The students where here on a school trip, Bakugou and Todoroki had followed along when though they had yet to receive their hero license. Honestly, Dabi had no idea how Shigaraki always knew where the students would be. There must have been a traitor in their class but he couldn't care less. Today, they were training in the forest. It was similar to the forest training they did back then. The only difference was that 1-B wasn't with them and Eraser head wasn't the only pro hero there. Endeavor had accompanied them. Seeing this, Dabi was excited. He could finally take down the monster that destroyed his whole family's childhood.

The students has just finished sparring and the sun had set. They gathered in a clearing where Eraser Head was briefing them about the next days activity. The villains had scattered around the area, keeping themselves out of sight while waiting for Shigaraki's signal to attack. When Eraser Head dismissed them, everyone started heading in the direction of the guest house. Eraser head being at the back and Endeavor at the front. Seeing that this was the perfect chance to attack, Shigaraki gave the signal to begin attacking.

All the villains respectively jumped out from their hiding spots around the area. The pro heroes instantly got into actions. Eraser head shouted towards Bakugou and Todoroki, allowing them to use their quirk to protect themselves. Dabi seized this opportunity to attack Endeavor and shot blue flames straight at him. Amidst the fight, Dabi could see that the Warp was fighting Eraser Head and the other villains where respectively fighting the students.

"Endeavor. This must be the first time we've met. But fear not, it would be the last." Dabi monotonously stated as he launched attack after attack.

"Dabi. I've heard about a villain with a blue flame quirk and was curious about his strength. Never would I have thought that you would look so small. Please give me a good fight, I've been itching to fight you and bring you down!" Endeavor shouted as he shot flames at Dabi.

The fight between him and Endeavor was brutal, both flames getting hotter and more powerful after each attack. Dabi looked around and saw that Eraser head and the Warp were still fighting, Toga and Mr Compress were taken down and the students were grouping together to battle the remaining villains.

"Do you think you have the luxury to look around? i've barely broken a sweat from your weak attacks." Endeavor shouted as he closed in for a punch. Something in Dabi snapped after hearing that. It was just like that time when he called me weak, called me useless, called me a failure! Dabi roared and charged in close to attack him.

As the fight prolonged, Endeavor could feel himself getting more and more tired. He had expected the same for Dabi however he wasn't expecting Dabi to still have that much strength and stamina. With that roar and charge, Endeavor wasn't able to guard in time and took the impact of the attack and fell backwards. Dabi, not giving a second glance, charged in for another attack. And it connected.

Seeing Endeavor on the floor powerless below him made him laugh. "And you called me weak? Look at yourself. And you call yourself a pro hero. You call yourself the number 1 hero after All Might. You make me laugh." Dabi activated a quirk and was about to finish Endeavor off when he heard it. He heard Shouto's voice.

"Toya-nii!"

shouto POV

Despite all the fighting that was happening, Shouto made sure to have Dabi in his sight. He was going to get his oldest brother back and today was the day. Dodging a knife thrown at him by Toga, he continued to defend against all the attacks coming at him and his friends. Occasionally, he would shoot ice to protect anyone who was unable to dodge or merely gave some support. He wasn't going to waste all his energy on the villains when he might need it to get his bother back.

When their group took down Toga, he looked around to gauge the situation. Bakugou's group had managed to take down Mr Compress and they were moving on to attack Twice. His group separated to join other groups that looked like they needed an extra hand. From the corner of his eye, he saw that Dabi had landed an attack on Endeavor. Shouto was honestly pleased, Endeavor definitely deserved it if Dabi was his brother. However, his happiness was short lived. He saw that Dabi had activated his quirk and was about to finish Endeavor off. When though Endeavor did deserve it, he didn't want his brother to become a murder.

"Dabi!" Shouto shouted. He had to get his attention somehow.

"Toya-nii!"

Dabi POV

"Toya-nii!"

Dabi stopped his attack just before it could hit Endeavor and turned to the voice. Endeavor, hearing his oldest son's name also turned in that direction.

Seeing that it was Shouto, Dabi got up from Endeavor and ran towards Shouto while activating his quirk, getting read for an attack. Shouto also activated his ice side to guard against the incoming attack.

"Toya-nii! You don't want to do this!" Shouto shouted after dodging an attack.

"I don't know who this Toya person is! I'm not him! I'm here to get rid of you and Endeavor!" Dabi replied shooting some flames against Shouto's ice.

The fight between the 2 carried out with Shouto only using his ice. Dabi was feeling more and more tired after each attack. The previous fight with Endeavor used up most of his energy. Suddenly, Dabi couldn't activate his quirk anymore. He must have used up all of his energy and Shouto must have realised it as well as he quickly shot ice at him. He couldn't dodge it, he had to take it. While expecting to be pierced by Shouto's ice, he didn't feel anything. Instead he couldn't move. Shouto had used his ice to stop him from moving, Shouto didn't intend to kill him.

"Dabi. Tell me the truth. Are you Toya-nii." Shouto walked up to where Dabi was and asked softly.

Dabi could see hope and sadness in Shouto's eyes. As much as he wanted to tell Shouto the truth and just wrap him in a tight hug, he couldn't do it. He couldn't risk Shouto's safety.

"Like I've said before. I don't know who this Toya person you keep talking about is!" 'Please just accept it. Your oldest brother is long gone. Long dead. Stop looking for him.' Dabi thought to himself after answering Shouto.

"Maybe if we tell you more about him you'll remember who Toya-nii is!" Another voice sounded from the distance. Both Shouto and Dabi turned to the direction of voice only to find Fuyumi and Natsuo there.

"Fuyumi! Natsuo! What are you doing here!" Endeavor shouted from where he was. He had also used up all his energy and wasn't able to move.

"Shouto called us here." Fuyumi answered, her glace never leaving Shouto and Dabi.

'Fuyumi? Natsuo? No, no, no! Why are they here?' Dabi inwardly panicked. Although he was glad to finally see them after many years, he didn't want them to be here were all the villains were.

Dabi quickly glanced around and noticed that most of the villains were taken down except for Shigaraki and the Warp but they were both in bad shape. The same could be said for the students. Many of them were injured and too tired t move. The only ones who were still fighting was Shigaraki, Eraser head and Midoriya. Everyone else who was down were staring in their direction watching everything play out.

"Toya-nii! Don't pretend! We know you remember us!" Dabi snapped back to face Fuyumi and Natsuo.

"Stop making me repeat myself! I don't know who you are and I don't know who this Toya person is either!" Dabi shouted while trying to activate his quirk to escape Shouto's ice.

Fuyumi and Natsuo had started running towards Dabi and Shouto. When they reached, Shouto used his flames to melt the ice. With the ice completely melted, Fuyumi, Natsuo and Shouto wrapped Dabi in a tight hug.

"What are you doing! Get off me!" 'No, no, no! The others cannot figure out what's happening! I don't want them to be in danger because of me!' Dabi struggled against the tight embrace but that only caused the three of them to tighten their grip. Tears were attempting to escape from his eyes but Dabi had to be strong, he had to pretend he didn't know anything. He had to do it no matter how painful it was. It is his duty as the oldest brother to ensure his siblings safety.

"Let go... please. I don't know who you are." Dabi said softly while choking back on tears.

"Don't lie Toya-nii. We'll help you remember everything. Natsuo, Shouto, carry on as planned." Fuyumi said.

Natsuo and Shouto nodded. It's time to get their oldest brother back.
