So let me get this straight.... There is no such thing as a Roronoa Clan on Wano, as there has not been a single mention of one.
But somehow, Ushimaru married a Roronoa, and 21 years ago, sent this mysterious woman, all the way across the blues, where they magically ended up in Shimotsuki Village.
And these halfwitted clowns have the gall to act like my conclusion is fucking far fetched......
