2 AnswersSingapore8 years agosome Bleach questions?
In bleach manga chapter 509, when Yama was fighting Juha. Yama said that ichigo's bankai still has room to evolve. This makes me wonder that ichigo limit haven't peak yet but what about dangai ichigo/FGT? Isn't that his maximum potential? It will be scary if FGT is just one of his power and not even close to peaking his potential. We will probably see ichigo unleash hell at the end of this final arc. Any thoughts guys?
