is one piece episode 739 filler?

At Kyros' house, Zoro and Robin remark on the bond Luffy has with Sabo, and Franky is in tears after hearing Sabo's story, causing him to short-circuit. Kyros then gets up, revealing that he heard Sabo's story from halfway through.

He offers the Straw Hats a drink, his hospitality toward them being in gratitude for them freeing Dressrosa. Robin and Franky fall asleep as Zoro drinks a bottle of alcohol, saying that he would like to spar with Kyros someday.

Kyros is pleased by the compliment, and Zoro hands the rest of the drink to him as he falls asleep in his chair.
