Guys i have a question.I am a BIG fan of the OP soundtrack.So i have a question.I have been searching for a soundtrack for over a month now.....but i cant find it.I am talking about one that plays not to often,but is SO cool and epic.I remember it playing twice:onece, when luffy has a flesh back when Bon clay saved the SH(link below),and second,in episode 513,when Chopper has the flashback about the separation of the SH.So if anyone knows what it's name is, pleas tell me XD.
