User blog comment:The ASL Pirates/4th Gear & Marine Ranks/@comment-4009563-20150316152819

Before I saw Red Hawk and Gear Second Buso, I was thinking Gear 4th would be Haki-enhanced form. However, currently I dont think there is a 4th Gear. (sorry for bad eng.) And ranks:

Luffy at full power (Admiral), Zoro (Btw. Vice Admiral and Admiral), Sanji (Vice Admiral)
