This sounds weird...

Hey,One Piece and 《银魂》 粉丝 out there!Did u realize that Hijikata's voice and Zoro's voice us the same...here let me 显示 u.....go watch some video of 《银魂》 Hijikata and Obe Piece Zoro....they both sound the same!!!Go look at 《银魂》 - Jump vs. Magazine(a video name for Hijikata,watch it.)and One Piece Clip-Sanji and Zoro (Zoro is the green headed guy)
And also watch "Sanji and Zoro fight again" just to check

TQ
