is one piece episode 969 filler?

Roger became the first-ever Pirate King, after which he went back to the island to pick up Shanks and Buggy. However, he knew that his days were ending as he was dying from a terminal illness.

The Marines, including Garp, as well as other pirates started fighting more aggressively to take Roger down. So, he decided to disband his crew.

He recalls his times in Fish-Man Island, where he heard voices from the sea creatures saying that there will be a new king succeeding Roger.
