this panel is just vague he may be using it here as well .. in other cases i'd admit that sparks are signs of haki.. again no loss if i do so here as well
how is a CoA clash with visible black lightning coming out vague?
why is it even controversial to say sanji will be able to use diable jambe on the RS?
this is literally just a costume.
the vinsmokes were thoughful enough to cater the suit to sanji and to give it to him.
dont you think they'd factor in that his favourite style of fighting is using flaming kicks?
stop the suit downplay please XD.
but DJ is a different case all together
no it is not. if he can use it on a normal suit, he can very well use it on another costume.
