Mirio had both girls by the hand, leading them to safety.
Until his legs gave out.
He collapsed against the wall, and struggled to even stand straight. "Eri... you.. must hide... take Avari and wait... wait for others to come... there are.. dozens of people here... to save the two of you... everything.. is going to be fine! You'll be okay," Mirio instructed, his body limp on the ground.
Chisaki, who had went up against Midoriya, held his hand out, a mouth forming on it. "Eri... Avari... it's your fault I had to die, again! Is that what you want?!" He yelled.
Avari tugged on the end of Eri's dress. "S-stay. I go... talk h-him..." Avari mumbled. She took steps towards the gaping hole in the wall that they had came out of. She climbed over it, slowly. Her small body struggling to keep its balance.
"N-not.. what.. I w-want..." Avari said, glancing at her sister, who was watching in pure fear.
"No, stay away! Avari, go back to Togata and Eri!" Midoriya instructed, but Avari only stared at the ground.
"Do you really think that this boy can beat me by himself?" Chisaki continued.
"N-n-no..."
"So what do you have to do?"
"C-come back.." Avari took a step. "B-but.. let e-every one go. L-let Eri go," she bargained. Chisaki thought for a moment.
"I suppose I could do that.. because it's so much easier to get hurt yourself than for others to get hurt for you, isn't it?" Chisaki spoke. "You have been very cruel to them, trying to get both of you to leave... it's truly a shame. You... you have been nothing but a liability!" She began walking, ignoring the calls of her sister, or even Midoriya vowing to save her.
Just then, the ceiling broke from above them, and Team Ryukyuu came crashing in. Midoriya handed the injured Nighteye to Uraraka, before reaching out to Avari. Before he could touch her, Chisaku created a pillar on which he stood on, holding onto Avari.
Avari could see the red cape she was wrapped in before, and subconsciously reached out to grab it. Nemoto separated from Chisaki, and Avari pushed herself out of his grasp. She sat on the edge, clutching Mirio's cape. She jumped off the edge and into Midoriya's arms.
Midoriya prepared to kick, but he accidentally lost control of his power, launching both him and Avari into the air. He began descending, and as he landed, a cold sensation was in his body. It confused him, using his power at 100 and not breaking anything. He looked at Avari. "Is this your quirk?" He asked, softly.
Avari shook her head, just as Eri ran over, her horn glowing. Midoriya gasped, his body suddenly feeling like being ripped apart. "She's unable to control her quirk. By some magical chance, she was able to activate it, but now she can't stop it!" Chisaki, in a horrid form, stood in front. Midoriya wrapped Eri around his back.
"Avari, you see the girl with the brown hair? Go to her. She can help you," Midoriya instructed. Avari nodded before stumbling over to Uraraka and Nighteye. Uraraka was careful to pull her closer. "What is she doing to Deku?" Avari shrugged at Uraraka, implying her lack of knowledge.
Ryukyuu instructed Uraraka to take Nighteye to the hospital, and so Uraraka left, leaving Avari alone.
More people came outside, talking in big words that Avari didnt understand. She turned, seeing Eri in tears, Midoriya on the ground in pain. She ran towards them, once again not listening to the people around her telling her it was dangerous. She placed a gentle, scarred hand on Eri, and the glowing of her horn stopped. Eri passed out close to Midoriya, who had lost most conciousness, while Avari collapsed next to him, laying her head on his back.
Midoriya did the work of getting both Eri and Avari situated on an ambulance and it was, unfortunately, a while before either of them awoke.
Sorry this one was a tad bit shorter, the other one will be the usual length!
