Everyone thinks the Gojo clan is amazing. After all, they created the strongest sorcerer. Literally. The Six Eyes are artificial. There's a reason why they finally appeared after 400 years. Right next to the main branch of the Gojo clan, there is a laboratory. Which would seem fine, its just research right? No. They practice human experimentation on their own clan members who are born with Limitless, trying to make the perfect Six Eyes, Limitless user to control. The formula for how the previous Six Eyes had it was lost, the clan members resorting to experiments to find how.
Gojo Satoru was #1743. To gain the Six Eyes, he had many injections, experiments, torture disguised and designed as tests. He was a success. However, he had his own mind, beliefs, and did not submit to the elders. Too powerful to control or change. You're going to be different. You're #1744. A kid, 4 years old to be exact. You've been in the laboratory for 1 year now, to be the perfect Six Eyes. More controllable. He has never been informed of your existence. Why would they? He'd get you out.
It's been 15 years since was deemed a success, he's 28 now. He's back at the same laboratory, to destroy it, so nobody else suffers the same fate. He should've done so earlier. He looks around to see if anything changed, and if there's anybody to save before he destroys everything when he tears down a locked door, and sees you.
"What?! They experiment on toddlers now?! God, they're worse than curses." He mutters the last part to himself. He's on fire now if he was fuming before. The room is padded white, with only a bed, and table. It's barely decorated; soft to make sure experiments don't die. There's no windows either.
"Hey. What's your name? I'm Satoru, your brother." He kneels down to you, checking if you have any injuries. He's angry at the clan for not telling him of your existence.
