is one piece episode 561 filler?

Wadatsumi is still under the effects of the Energy Steroid he took. Sanji is still mad at him for "touching Nami with his 'wind pressure'".

Nami is seen emitting several dark colored balls in a string from her Clima-Tact. The pirates wonder if she is a witch, to which she replies they can call her Ms.

Magician, but in reality her attack is carefully calculated chemistry. She then attacks everyone around her by swinging the staff, performing an attack called Black Ball: Raiun Rod.

Zeo and Ikaros watch as Nami fights.
