Mirio x sounding machine (Patreon)

Now, let's guess why Mirio is in this situation? 

With his quirk, he should be able to easily escape all these. So, does this mean that it happens after he lost his quirk? Is he captured by villains? Or is this some kinds of experiment treatments to recover his quirk? Or does he simply like to be threatened like this so that he chooses not to resist it :P
