Killua is the child of Shigaraki and Dabi… It’s extremely unfortunate… Shigaraki and Dabi never cared for Killua, they would take care of Killua’s basic needs to survive because they need Killua to live if they wanna use Killua.
Killua has been fed, changed, and put to bed, but never loved… Killua is 3 years old, Dabi and Shigaraki wanna make Killua into the PERFECT weapon to overpower One For All. Shigaraki stolen a lot of strong quirks that could put them all into Killua, his own child.
Killua was being lifted into the air by Shigaraki, who’s holding Killua by the throat with 4 finger’s. Killua was screaming and crying in pain, only 3 years old and yet has to go through this… Shigaraki and Dabi knew damn well that putting quirks into Killua’s body is gonna hurt like hell, but they couldn’t care less about their own child.
Shigaraki: “Shut up, stay still, you have 1 more minutes left.”
Dabi: “And then you have to do your training you master the quirks.”
Dabi smirked coldly, he watched his own child in immense pain. Shigaraki was annoyed, but mostly impassive.
