How does Zoro speak with a sword in his mouth? When using Santoryu (Three Swords style), Zoro holds a sword in his mouth. How is he able to speak normally, without the sword falling?
The official explanation given by the author, Oda Eiichiro, in his SBS1 column, is that it is Zoro's heart speaking. This may not sound any more convincing than Artistic License, but One Piece regularly relies on such unusual logic, so it is not entirely out of place.



1 SBS (Shitsumon wo Boshū Suru, roughly meaning "I'm Taking Questions") is a Q&amp;A column in which Eiichiro Oda answers questions sent in by his fans.
