"Shokugeki no Soma" chapter 155 is already available for online reading thanks to Manga Reader.
The chapter is beginning of shokugeki between Ryo and Central's Rentaro as the former tries to save the club Alice won through a separate shokugeki. Before any predictions and speculations for the upcoming chapter, here's a brief recap of the latest events in the manga.
Ryo and Rentaro started their shokugeki and it was revealed that the food war will focus on salmon. Through flashback the battle between two chefs are already determined thanks to Alice's decision to continue the research society she won through cook off.
Meanwhile, Soma's interaction with Momo who was also attending the match was not going well but Alice noted that the actions of Momo should be expected since it's her first time interacting with Soma.
Central's Rentaro acknowledged the ability of Ryo to bring out the best dishes when it comes to seafood. Because of Ryo's skills, Rentaro decided to bring out the special cooking equipment in the competition.
Blogger MangaKaido speculated that Rentaro is not the only one who will take advantage of the special equipment in the competition since experience has taught Ryo a lot when it comes to competition, "He's like Soma in that respect, using whatever can give him an edge in the battle...It would be really weird if Ryo didn't start using the techniques that regularly beat him."
The chapter also revealed that the chefs from Central did not choose any theme and they are practically keeping their best cooking skills a secret.
User JonDou at Manga Helpers has a speculation of conspiracy in the competition, "I think the reason that Central has defeated everyone at their specialties is that they are receiving special coaching that targets particular chefs. I don't think the Central chefs are really as good as they are being passed off as." If this is true, then Ryo would have an upper hand soon if this secret is revealed.
