Brainwashing (洗せん脳のう Sen'nō?): Hitoshi's Quirk allows him to put someone in a state where they are forced to obey whatever he commands. He can only activate this power when his target verbally responds to something he says. Brainwashing needs to be intentionally activated and will not take effect if Hitoshi doesn't want it to.

Though he can have multiple people under his control at once, he can only activate his power on one person at a time.
