Roventiar says Kaido's son doesn't appear at all, not even a silhouette.
I honestly could believe that because usually these spoilerheads leak the most "exciting" or a portion of the most exciting parts of the chapter. Not to say there isn't anything else interesting in the chapter, but the last 3 chapters were:
- Jinbe returning
- Kaido's son/tobi roppo legs
- Tobi Roppo designs
as the initial spoilers. So I wouldn't be surprised this is partially what this chapter focuses on. Clearly there is a ton more, like last week where we didnt' know about the Onigashima double spread or Queen's whole ballad before the Tobi Roppo are revealed.
I just go into these things with my expectations low after initial spoilers.
That being said,
@Roventiar, didn't you specifically say you weren't getting spoilers anymore? How do you know Kaido Jr. doesn't show up this chapter?
Edit: Reading his post, I think he's just implying it is "unconfirmed", not that its not real.
