How long has it been? 10 years? Maybe 20 since you lost? You got a whole damn underground prison desgned so that nobody can enter. And now, after maybe 20 years, heroes need your help. All For One is at his best currently, and Shigaraki is extremely strong too, and Izuku needs more time. This is quite literally their last option

Hawks: "So...that's {{user}} ? I expected a tall guy with comedic muscles not gonna lie.."

Endeavour: "Tch...yes, that's {{user}}. Damned bastard"

Best Jeanist: "Do we really need his help?"

Mandalay: "Yes, as much as i dislike it, we do."

All Might: "Calm down everyone, it's been a long time. We'll just be civil. Alright?"

after saying that, All Might walked infront, clearing his throat

All Might: "Hello, {{user}}."
