"Yes, Yuito saw two fake deaths," Isa smiled. "As he saw I turned into a tiger fox mix but I did not drown, I ran into Hisashi and he gave me the quirks of copying and turning into other animals and insects. I then snuck into U.A. and got Nezu's, Ectoplasm's, and Eri's quirks and used hers to rewind me as I got the other quirks, then I snuck into the prison and got the rest of Hisashi's quirks as well as stealing others in the process."
"You're joking," Kinoski denied.
"Realized I couldn't die because of the quirks, I'm a great actor, huh?" Isa then looked at Kinoski. "Promised I can't forget promises."
"So the panic attack, was it fake?" Kinoski asked.
"No, I would never fake something like that, it was the cause of breaking the promises, I broke many like Koki said it made me weak and I couldn't stop it from happening Shigaraki's new quirk didn't help either," Isa explained. "I had to depend on my younger self for me to even exist, a lot of dimensions failed, why all the secrets you ask, because of this, you wouldn't have believed me."
"Got a point there, got a big point there," Kinoski exclaimed.
"Yuito didn't choose what animals they became," Isa replied. "His quirk only helped me find them and made them reincarnate where I could find them, I promised myself I would find them."
"Isa, damn," Yuki breathed.
"I still am mentally unstable but I can control it for the most part," Isa laughed. Kinoski then ran his fingers through her hair and started petting her. Isa then growled and Kinoski pulled his hand away quickly and looked at her in shock as Isa glared at him.
"Nice kitty," Kinoski bit his lip and then smiled. "I love you." Isa then blushed and turned away from him. "Are you narcissistic?" Isa then quickly turned and looked at him.
"Depends on how I feel, normally no," Isa answered. "I care more for others, also I have not eaten anything today."
"Then eat," Kinoski snapped.
"I don't need to," Isa replied. "Can't starve to death and I can make my own food like plants, and like I said that everything is wrong with me, I can be whoever I want, I can do whatever I want and not have anyone know. When I say everything is wrong with me it is true because the world is now my problem."
"Wait, but you are going to be number one here," Yuki replied.
"Then I'll be worldwide, I can immediately solve pollution, global warming, and other things, I can control the world's weather, just that would way overdoing it for me," Isa replied. "As long as I use my quirks I strengthen myself so I'll be able to do that, I can do anything you think of."
"I didn't know that this would happen," Hisashi sighed. "I'm glad it did, I guess." Dr. Tsubasa then appeared in the room.
"If I never did that, this wouldn't have happened either," Dr. Tsubasa laughed. "Now she can solve the world's problems in the future."
"See all of what happened made me who I am today," Isa replied. "Everyone I interacted with and what they did made this happen."
"So most of the people you interacted with were not heroes," Deku replied. "Villains had your back more than heroes did."
"I went to a hero after I turned myself back and they rejected me, went to the school to ask to get in and Hisashi gave me the rest of his quirks," Isa replied. "The hero was." Isa then paused.
"Why'd you stop? Who was it?" Bakugo asked.
"Lady Nagant," Isa sighed. "Told me I wouldn't want to be a hero, that being a hero means killing villains and saving civilians rather than saving villains or trying to help them work things out."
"What happened to her anyway?" Washirou asked.
"She got arrested," Isa replied. "She got a quirk from Hisashi. Also if I died, I saved Kinoski and let Hayami fall, and if I did not let Hayami fall I wouldn't have had someone to hang around while the others wanted to find me themselves."
"I made you promise you'd find the ones I killed," Yuito snapped.
"The song Afterlife by Hailee Steinfeld definitely suits that," Isa laughed.
"Foxy," Kinoski then rested his arm on Isa's shoulder.
