I can't know whether the need to give up our powers is genuine. It is possible that it is a ruse to get us to return our power. However, I'm still not sure whether these are our actual quirks—abilities—in the first place.

[As someone who's worked with All for One for more than a decade, he has a heightened skepticism about these matters. He's seen for himself how much abilities can be manipulated by one with such a strong power, and how such a power can alter the world itself.]

However, it is also possible it will make a difference, even if it is a deception.

[Kurogiri nods, having taken the question as a hypothetical. He takes no offense. It's not a thought that's new to him. He's also considered the possibility that Shigaraki himself might ask him to harm someone.]

It depends on what is meant by harm. I would restrain or incapacitate someone if it were necessary to protect them or those around them.

[He pauses. Things are different now than they were before—before he'd seen Hizashi and Shouta while incarcerated in Tartarus. The decision he's come to may be strange, but he's sure it's the right one. Saying it out loud feels odd. It almost feels like his voice doesn't fully belong to him, but he says it nonetheless.]

Shirakumo Oboro will not hurt others, and I must remain true to that.
