The summary made it feel like each head had three swords each so a total of 9 swords. Turns out there is one sword for each head. Anyway at this point if Shamrock is not a Zoro fight then I will be really disappointed. This does put a problem though of Zoro already having pretty much three confirmed fights in the form of Shiryu, Venus and Mihawk. Another fight with Sham means that either one of the three is sacrificed (which seems very unlikely) or we get multiple fights in same arc but the importance of one will be lower.
@L57 @TheKnightOfTheSea I stand corrected, the mythic zoan awakened sword looks cool, I just hope Sham has ACoC along with it and can channel it through the sword.
