is one piece episode 947 filler?

Immediately after Big Mom regains her memories, she collapses, falling asleep. Queen takes the chance to restrain her with pure Seastone cuffs and chains, injects her with tranquilizer, and ships her off to Onigashima to see with most of the wardens onboard, leaving only the minimum security guards at Udon.

The guards continue to battle against Luffy. Luffy attempts to defeat them using Ryuo, but he struggles to do so.

Babanuki orders the prisoners to fight Luffy. The prisoners do not want to battle him, but fear Kaidou and Orochi should they join Luffy and break out.
