Satoru Gojos son Killua? Killua adventure

Small talk and training

Killua?" Gojo asked as he walked into his room. "Yeah, what's up?" Killua asked, pretending everything was fine. "So, uhm, everything okay? You're all sweaty and stuff. Did you have a nightmare?" Gojo asked. "No, it's nothing. Just go," Killua replied, turning away. Gojo approached Killua and sat on his bed. "Oh, come on, Killua, you can tell me if you had a nightmare, my little Chibi," Gojo said, lifting Killua and setting him down next to him. "Did you really have to carry me?" Killua asked annoyed. "Yeah, besides, could you just tell me what you dreamt of? I mean, come on, just tell me, Chibi," Gojo said, grinning. "First, stop calling me Chibi, and second, why do you want to know so badly?" Killua asked. "Well, when you were a baby, we used to call you Chibi, and why I want to know? I just want to help you. I don't want my little Killua to have to sleep with a nightmare," Gojo said. "Come on, just tell me," Gojo urged. "Fine. So, I had a nightmare about that Sukuna guy, you know," Killua lied. Gojo knew Killua was lying but pretended to believe him. "I see," Gojo said. "Yeah, um, could you tell me exactly how everything went down with that Sukuna's blood and all?" Killua asked. "Okay," Gojo said, becoming serious. "So:"

Storytime (10 years ago):

Sukuna and Gojo were in a fierce battle, both covered in blood and injuries. "Sukuna, I don't believe you're stronger. I WILL KEEP GOING," Gojo said, bursting out and attacking Sukuna, but he countered. "This is getting ridiculous. Maybe I should..." Sukuna laughed. "Gojo, Gojo, Gojo, you pathetic Jujutsu sorcerers. Hey, Gojo, how's your little son doing?" Sukuna asked, smiling. "What's it to you?" Gojo replied. "Oh, I don't know, just asking. Maybe someone's on their way to him, you know," Sukuna said, smiling. "What are you getting at?" Gojo asked. "TELL ME!" Gojo shouted. "Well, maybe a part of me..." Sukuna yelled and ran away. Gojo chased after him. They continued running, but then three curses appeared from the sky, one holding Killua. "KILLUA!!" Gojo shouted and ran towards the curse, but it was fast enough to hand Killua over to Sukuna. "I don't care if I die. I'll come back," Sukuna thought. Sukuna screamed and cut a small wound on baby Killua's chest, then tore off a piece of his own finger, letting the blood drip onto Killua's wound. "Perfect," Sukuna whispered. Gojo ran towards him, punched him in the face, and grabbed Killua.

The end.

"That's it?" Killua asked. "Yes, once the blood enters your body, you are the chosen one to defeat Sukuna. Do you understand?" Gojo asked. "Y-Yes?" Killua replied uncertainly. "Hmm, let's go outside," Gojo said, and Killua followed him.

"So, Killua, since you have the ability to see curses, you can also learn some curse techniques. First, close your eyes, breathe in and out, then use your Ren. When you use your Ren, keep using it until you feel a strong power within you. Once you feel that power, release it. Understand?" Gojo asked Killua. "Yes," Killua answered and did as Gojo instructed. It was easier said than done because Killua couldn't feel that power, and when he did, he either released it too early or too late. It had to be right in the middle, with an even strength, neither too weak nor too strong.

"Keep trying, Killua. I don't blame you for not being able to do it at the moment, okay?" Gojo encouraged. Killua nodded and concentrated. "Someday, you'll get there, Killua."
