"Koki stop," Isa laughed.
"Don't come near me I'm going to commit arson, Everyone can commit arson, Forget I committed arson, go commit arson, help me commit arson, I committed arson," Koki continued.
"Koki," Isa laughed as he paused for J.
"Just commit arson," Koki tried to continue but his hand covered his mouth and he looked at Isa.
"I said stop," Isa replied. Koki then laughed as his hand stopped covering his mouth.
"Isa what have you done to him?" Kagami asked.
"He was a mature spider and I didn't know he was the spider until later," Isa sighed. "Those spiders can survive up to ten months so he was a fully grown adult because it has been a year, I also got the first two quirks about eight months ago ."
"Carbon three, Hydrogen five, Nitrogen three, Oxygen nine," Koki replied. "Can I have some?"
"What the hell is that?" Dabi asked.
"Nitroglycerin," Isa sighed.
"Twelve thousand nine hundred fifty-six times seven hundred-thirty-four is nine million five hundred nine thousand seven hundred-four," Koki replied.
"What the," Yuki replied.
"Koki," Isa replied. Kazuko and Torako then walked in.
"Isa's favorite number used to be nine hundred sixty-three, now it's nine thousand, seven hundred twenty-five," Koki laughed. "That divided by twenty-five is three hundred eighty-nine, all those numbers add to twenty and twenty subtracted to that number is three hundred sixty-nine."
"I'm sorry?" Katobuki asked.
"Why the hell would those be your favorite numbers anyway?" Kahida asked.
"Nine hundred sixty-three was my favorite number because I was a strange kid and I loved every number and I decided to do the random number from one to one thousand," Isa explained.
"Okay, that makes sense, but why is it now nine thousand seven hundred twenty-five?" Kinoski asked.
"Kinoski's favorite number is nine, Bakugo's seven, Koki's used to be eleven, and Yuki's is five, now add both the one's together and that would be two, nine seven two five," Isa explained.
"Mine's now seven," Koki laughed.
"Why, is it because of Bakugo?" Kona asked.
"No, after I found out Isa's new number I added all the numbers together giving me twenty-three and then added eleven which was thirty-four, and then added three and four, also it's in the middle of nine and five, but Isa's new number has a significance to her old one."
"Yeah, yeah we get it Koki," Yuki sighed.
"Wait, you know how you divide by twenty-five and then subtract twenty?" Koki asked.
"Yeah, what about it?" Yuki asked.
"Kirishima's favorite number is twenty-five and Kona's is twenty, being the only two siblings Isa lived with and the person they ended up with," Koki laughed.
"Koki, quit being a smartass," Isa laughed.
"That is kind of interesting though," Kinoski replied. "And very unfortunate."
"What's my favorite number?" Haruki asked.
"Ninety-seven," Koki replied. "Which are the two numbers at the beginning of her favorite number."
"And our father's?" Haruki asked.
"Do not answer that," Isa objected. Koki then looked at Isa with shocked amusement.
"You, Isa, what the hell," Koki beamed. "That is so unfortunate, how the hell did that happen?"
"What?" Haruki asked.
"Okay your mother's favorite number is seventy-two and your father's is twenty-five," Koki replied. "I mean, ninety-seven, seventy-two, twenty-five, it's the order of their age, don't duplicate any numbers and it's nine thousand seven hundred twenty-five."
"Wow, that is really unfortunate," Kazuko laughed.
"Wait, and Oboro's is ninety-five," Koki replied. They all then looked at Isa.
"What?" Isa laughed.
"The other thing that is unfortunate is Wakumi, my mom, Nori, and Akima," Koki replied.
"What do you mean?" Kagami asked.
"Koki stop, stop it," Isa laughed.
"Try the numbers backward and in the order she interacted with them Nori's is fifty-two, my mom's is twenty-seven, Akima's is seventy-nine, and Wakumi's is fifty-nine," Koki replied.
"Well Isa has a very unique number," Kagami replied. "Also Isa saw you only three times while she was at that house, why were you going to the park saying you were hanging out with her?"
"Uh, well, I was listening to music," Koki laughed. "Music is the best medicine."
"Where'd you hear that from?" Kagami asked.
"Uh," Koki looked at Isa and started laughing. Isa then chuckled.
"It was me," Isa replied. "There was a spot in the park that hardly anyone went to and Yuito and I would go over there occasionally and that's how we bumped into Koki, it was like a hidden spot."
