This is not the only series in which an old man can become powerful. That seems to be a constant in anime. I think that once they get out, that old man will be a rallying point for allies. Luffy will as well with his tales of battle and his support. I am glad that this chapter confirms that Sentomaru is using that advanced haki, a fitting ability for the man who claims to have the strongest defense in the world. Probably an exaggeration, but I would think that fighting him would manage to give Luffy a boost in his advanced haki. As mentioned he seems to adapt and get stronger through a trial by fire and I think the flames in this game need to be stoked a bit more to really help him. Also, good to see that my prediction is correct. That ability to see the future is coming in very handy now.
