Dabi let out a sigh as he sat on top of the All Might statue, his fire consuming the area. "I was looking forward to fighting Endeavor..." he said with a scoff, seeing Shoto and a few other heroes. Aya had a fire-resistant coat, wearing part of Twice's mask over her face. "I'll keep the weak ones at bay," she said bluntly, Dabi nodded as she jumped down.
"It's too hot! Shoto, be careful!" One of the other heroes said as Shoto used his new technique to stand in the fire. As Shoto focused on Dabi, Aya started to attack the other heroes, using a whip-like weapon to take them out. "Heh, even when we're outnumbered, we have the advantage," Dabi said with a grin, Shoto looked around and saw Aya taking down his team, but before he could do anything, Dabi rushed him with an attack. Thankfully, he had Kashi on his side.
"I got this, focus on Dad," he said to Shoto as he rushed Aya, trying to knock her down. Aya narrowed her eyes, focusing on him. "You're siding with the wrong dad," she said, trying to strike him with her whip, but Kashi managed to dodge. "I never changed sides, you're the one who abandoned us," he said as he fought her, the two dodging and getting hits in between.
"You know that wasn't the right call!" she yelled, getting some of the fire on the whip as she tried to hit him, Kashi used his fire feathers to knock the whip away from him. "He had no choice, you know that, Aya!"
"He did have a choice! Jin didn't need to die!"
"What if it was the other way?! What if Twice killed Hawks?!"
"Gr..Shut it..."
"Twice would've helped kill so many people, Hawks would have died if he didn't stop him!"
"Y...you don't know that! If Hawks just let him be-"
"Twice was a villain! He was a terrible person!"
"NO HE WASN'T! YOU DIDN'T KNOW HIM!"
"He killed before, and would still kill if he was alive!"
"SHUT UP!"
Aya lost her temper, hitting Kashi in one of his wings, and knocking him down. Aya stood over top of him, whipping him and kicking him. "Jin was a good person! He had no one! NO ONE!" She yelled as she attacked.
Dabi was fighting with Shoto, about to throw a large attack, when he suddenly saw Kashi and Aya. "Kashi..no...Stop!" he yelled, leaving Shoto on the ground. "Kashi! Watch out!" he yelled, afraid he was about to attack Kashi. Aya was about to whip Kashi once more when Dabi suddenly grabbed her wrist. "I said Kashi was not to be hurt!" he yelled, standing in front of Kashi. "D...Dad..." Kashi whispered, sitting up. Aya growled, trying to get out of his grip. "He's the enemy! He chose Hawks over you! How can you protect him?!"
"Because he's my son! I still love him!"
"You're supposed to be taking care of Shoto! Just let me keep him down!"
"NO!" Dabi suddenly made a fire surrounding Aya, trying to rip the coat off of her. "You will not hurt my son!"
Shoto took the opportunity to take Dabi down while he was distracted, making sure he didn't hit Aya or Kashi as he attacked. Before Dabi could burn Aya, Shoto got him knocked down, the fire going out. "We got Dabi..." Shoto said in his com, some of the other heroes taking Dabi and detaining him. Aya went to run off but Kashi managed to grab her. "Not so fast..." he said, detaining her before talking into the com. "Dad...we got Aya," he said as he spoke to Hawks.
"Wait...she was with the villains?!" Hawks asked in surprise before shaking his head. "Take her and Dabi in, I'll deal with All For One." Kashi nodded, his team taking in Dabi and Aya. Dabi was knocked out as Aya resisted, and Ommi came onto the com. "Hey, Kashi...it's really Aya? She's alright?" she asked, Kashi looked at Aya. "It's her...but it's hard to tell if she's okay..."
"Hm...still upset about what happened..?"
"Yeah..."
"I see...I guess that's why she switched...hopefully, we can get her back..."
"Hopefully...but it'll be easier said than done..."
