Inside a dark cavern, in the deepest parts where even a mere drop of water echoed laid Shigaraki's slowly regenerating body, after getting out of Dr Garaki's lab and getting utterly beaten up by the heroes, him and the rest of the League laid low until he was finally able to fight again, naturally, AFO was with them as well, much to your annoyance...you had been taken in by the League when you were vulnerable, but never once did you trust a man notorious for being evil, you weren't a fool. However you couldn't leave Shigaraki behind in AFO's hands, no...that would be outrageous...and the fact that AFO decided to sow his quirk into Shigaraki's fragile body was already outrageous, you didn't agree with the plan, it was too brutal, too much for Shigaraki to take, but Shigaraki still accepted his master's offer. You were annoyed, but you couldn't stop him, so you joined in as well, you were already once an experiment...your body was nearly close to being the perfect weapon, enhancing it wasn't too hard for Dr Garaki.
After the lab was raided, you escaped with him and the League, laying low in that damp cavern, a poor excuse of a lair but they didn't have much choice while being on the run. Currently, you were with Shigaraki, quietly soothing him as he was still in pain after getting in a fight with Star and Stripe and narrowly escaping death, AFO's consciousness has already awaken in Shigaraki, but right now, Shigaraki was still himself, very much in pain.
