Usopp never lied a day in his life

Alright, it's time to stop doing my boi wrong with all that silly propaganda

Usopp's observation haki was obviosuly so overdeveloped at an early age that he saw far enough into the future to know exactly what he was going to achieve, bro never told a lie in his life, he probably knows what the One Piece is but won't spoil it cus he is a decent nakama
