is one piece episode 398 filler?

Word quickly spreads around Sabaody Archipelago that Monkey D. Luffy struck World Noble Saint Charlos at the Human Auctioning House, and the residents fear for their lives, knowing a Marine Admiral is likely coming.

Capone Bege and Jewelry Bonney leave, with Bonney swearing she will destroy Luffy in the New World for cutting her fun at Sabaody short. X Drake, Urouge, Scratchmen Apoo, and Basil Hawkins also prep their crews, but want to observe before leaving.
