In the Ohara BC we know that then Admiral Sengoku oversaw the entire BC operation. In addition two of the VAs that participated directly in the BC were Kuzan and Sakazui (now Admirals Akoji and Akinau). That sill leaves three VAs unaccounted for. Although it's possible that these three VAs were just random characters, and not important to the overall story, I belive that we have been introduced to at least one of these VA's already, but Oda never mentioned that they participated in the BC.
My candiates for these VA's are:
- Admiral Kizeru
- VA Crane
Like his Admiral counterparts I belive Kizeru was a VA during the BC and like Akoji and Akinau he got promoted for his duties relating to the BC.
Although it maybe hard to belive that Crane has been a VA for 20+ years remember there are different levels of VA's. You have the VA's of the four Blues (such as Garp), you have the Marine HQ VAs, and you have Marine HQ VA's with special privilages. IMO during the Ohara BC Crane was the VA for the West Blue and it would be convient for Sengoku to chose a VA that is in the same general area as Ohara. Some proof to backup this theory lies in chapter 234. During the Marjeola(sp?) confrence Crane reconizes Latiffe, and she says that he was a peacekeeper from the West Blue who was thrown out power because of his violent ways. After the BC Crane was promoted to Marine HQ VA, and also had the privlage of being the closest adivsor to newly elect Chief Admiral Sengoku.
