[ Yoshiko's still super hyped up on the idea of 'magical singing powers.' So when You suggests going somewhere else, she nods. ]

What about if when you sing, we first find someone within that half a mile. And after you sing, we ask them if they heard you singing and if your magical singing powers affected them. [ This is a perfect idea and nothing can go wrong (except this is Yoshiko, she knows that things might go wrong to begin with) ]

Give me just one moment— [ and then Yoshiko just fuckin CHUGS some of her sugary alcoholic monstrosity before looking back at You with a smile. ]

There we go!
