"Wait you're?" Bakugo beamed.
"The one and only," Isa laughed.
"Wait, no way, sis," Bakugo exclaimed and hugged Isa tightly.
"Bakugo was your brother?" Yuki snapped.
"Are you kidding, she was not only my sister she was my best friend," Bakugo cried.
"Oh lord," Mitsuki sighed.
"What?" Oboro called.
"They both used to stay up all night throwing their sibling parties after Isa got him to sing, and they both were caught cuddling each other multiple times," Masaru sighed.
"I wanted to kill them, I hated both of them, they got high off of each other," Mitsuki sighed. Isa and Bakugo burst out laughing.
"So you're the reason Kacchan was mean to me?" Deku sighed.
"I lost Isa, and I felt I would lose you too," Bakugo snapped. "I'm sorry."
"You didn't have to say what you did though," Isa pointed out. "You went too far with that."
"Shut up, you idiot," Bakugo snapped and wiped away his tears.
"I've never seen Bakugo so happy before, is he crying?" Mina beamed.
"Yes," Isa laughed.
"Wait, didn't you say Shoto was like a brother to you?" Dabi smirked.
"Not exactly, but yeah," Isa answered.
"I'd gladly adopt you," Endeavor joked.
"Really?" Isa replied. "I can make that happen."
"Uh, okay," Endeavor hesitated.
"Wait, you can't be serious," Shoto replied. "This is a joke right?"
"No, I can make it happen," Isa laughed.
"I'll do it too," Aizawa joked.
"Zawa," Oboro snapped.
"We did it first," A voice filled the room.
"Nighteye," Isa laughed as Stain and Nighteye appeared. Deku, Mirio, and Eri beamed in excitement.
"I'm sorry, what just happened?" Oboro faltered.
"Isa's now my sister," Dabi laughed.
"She's mine too, you moron," Shoto sighed.
"What do you mean Sho?" Dabi laughed.
"You did that on purpose, she said you felt like a brother to her, not me," Shoto sighed.
"Yeah, I know," Dabi chuckled. "I didn't expect this to happen though."
"You two aren't the only ones though," Isa pointed out. "Fuyumi, Natsuo, Eri, and Shinso did too."
"Right," Aizawa smirked.
"Two dead people adopted you," Deku pointed out.
"Yeah, that's fun," Isa laughed.
"Wait, is Nighteye dating Stain?" Deku asked.
"No, they are ghosting," Isa replied.
"Very funny Isa," Nighteye smirked.
"Anyway, let's see it seems like Deku has two adopted siblings," Isa replied.
"What?" Deku exclaimed.
"I didn't adopt anyone," Inko protested.
"Yeah, it wasn't you," Isa replied.
"Wait," Inko hesitated. "Hisashi?"
"I'll explain," Isa replied. "Deku is not All Might's secret love child, Shoto, Deku's quirk was handed down from All Might, All For One had a brother whose quirk allowed him to pass down quirks and when passed down they get stronger, so when All For One gave his brother quirks forming One For All, it was passed down, Deku is the eighth."
"I-Isa," Deku snapped.
"That's not all, Deku was actually born with a quirk that could make him telepathically burn things and breath fire, but it was taken from him because it was an overpowered quirk, also the doctor that did that ordered the same for me, and the current All For One gave me back my quirk and he is a replacement and is actually Hisashi, he left to keep his son and wife safe." Everyone then looked at Isa in shock.
"You really do know everything," Oboro gasped.
"Toya is alive," Shoto blurted.
"That was next," Isa laughed.
"Way to drop a bomb Shoto," Bakugo joked. Isa laughed and glanced at Bakugo.
"I didn't want Isa to say it," Shoto snapped.
"I didn't want to," Isa chuckled. "So thanks."
"T-Toya's alive?" Natsuo blurted.
"Waking up to Endeavor this morning was a surprise," Dabi grinned and looked at Isa.
