Chapter 19
"Yeah, I'll read it this time," Isa replied and reached down and grabbed the note. "It says, the results proved that because they were born on the same date, they are fraternal twins, they have different fathers."
"Makes sense why we have similar hair I guess, our fathers both had deep blue hair," Inosuke replied slowly.
"Well at least we know, anyway, you see how strong Inosuke is?" Isa replied.
"Yeah, what about it?" Inosuke snapped.
"Well, I read Amaya's mind earlier, she was thinking, I see his hair on her, and that my father was one of the strongest demons she's seen, so if Inosuke is as strong as he is, think about how strong I'm going to become," Isa answered.
"She's right, if both Inosuke's father and your mother were strong, think about Isa's father, who was a demon and stronger," Tanjiro replied.
"No way, that's so cool," Zenitsu replied. "I told you you guys were siblings."
"Don't even start with that, Zenitsu," Isa and Inosuke snapped at the same time. They then looked at each other and burst out laughing.
"You know," Inosuke stopped laughing. "You're pretty great, I'm glad you're my sister."
"Twinsies, from different fathers," Isa laughed. "And Inosuke, that's adorable."
"Stop reading my mind, and yes, my mother used to stroke my head when I was little," Inosuke replied. "Probably why I cuddled you last night."
"I softened you up," Isa laughed.
"Yeah, yeah, whatever," Inosuke sighed. "Now shut up and let's get going." Inosuke walked off and then stopped when nobody followed him.
"Inosuke, why are you nicer to her?" Zenitsu asked. "Why can't you be nice to me?"
"Because he's a Tsundere," Isa replied.
"What's a Tsundere?" Zenitsu asked.
"A person who acts cold, blunt or curt and is nicer to certain people they like, there are other definitions but, that's the one that fits Inosuke," Isa explained.
"What about Tanjiro," Zenitsu pointed out.
"He just knows when to keep his mouth shut, for the most part," Isa replied. "Right Inosuke."
"Yes," Inosuke snapped. "Are we going or not?"
