is one piece episode 489 filler?

Shanks stands firm before Akainu while Garp recognizes the former for corrupting his grandson into being a pirate. Almost all the pirates and Marines are surprised, while an amused Teach catches notice that the Red-Haired Pirates had arrived.

While Law's submarine sails away, his crew members race to save Luffy and Jinbe who are rapidly losing blood. As they prepare for transfusion, Bepo reminds his captain they need to go underwater soon.

The Marines learn that Shanks' crew had a run-in with one of the other Four Emperors, Kaido, yesterday.
