is one piece episode 227 filler?

The crew is shocked to see Robin panicking at the sight of the man they met, and immediately faced him, ready to attack. She tells the crew that the man is marine Admiral Aokiji one of the three Admirals: Akainu, Aokiji, and Kizaru; one of the World Government's three greatest power.

Usopp questions why Aokiji is there but Aokiji ignored him and turned towards Nami and tells her that she is a "super-babe", which angers Sanji and Usopp. Aokiji explains to them that he is only out for a walk.
