Yeah Joa is stronger than the 3 disciples but I don't know what to make of that character. It's not even clear if Joa is a female. By appearance that is obviously implied but everybody refers to Joa as a he. I don't know if it's Japanese gender neutral terms but I've found that whenever it is unclear they either are almost always male or remain unrevealed when it comes to anime. Now that it's confirmed not to be an evil Frohze, that may be another hint at the gender. Idk. But it's not a very relevant subject. Also yes, Komatsu's food luck will catch up. It was deliberately shown that Joa and Komatsu were making paths at the same time. I just wish Komatsu would stop being so whimpy. He needs Gourmet cells. He already has Food Honor, food immersion I believe, and unmatched food luck and a Deeous knife. If he got Gourmet Cells he would jump to a level above pre food honor Toriko immediately most likely.
