is one piece episode 263 filler?

Blueno appears behind Sanji using his Doa Doa no Mi powers and uses Rankyaku to send Sanji flying backwards. Robin and Sogeking watch in horror as Sanji almost slides off the train car.

Sogeking wonders how Blueno did that and Blueno slowly starts walking toward them. Sogeking stands in Blueno's way but as Sogeking briefly talks with Robin, Blueno disappeared.

Blueno suddenly appears behind Sogeking and Sogeking turns around in horror.
