is one piece episode 968 filler?

Oden's adventure with the Roger Pirates led him back to his homeland, Wano Country, since there was a Road Poneglyph there. However, Toki fell ill from the fatigue from several years of adventure with Oden, so Oden was forced to leave her and the children in Wano.

Inuarashi and Nekomamushi also decided to stay behind. Oden was also willing to stay, but Toki insisted that Oden sail with the Roger Pirates.

As he set sail once again, he noticed a slight change in Wano Country. Meanwhile, Orochi and Higurashi expressed disappointment that the Kouzuki Family now had a viable heir after Oden.
