is one piece episode 901 filler?

Gazelleman barks with laughter as he speeds into the horizon, kidnapping Tama, and with Batman's arrow attacks drawing their attention, Luffy and Zoro are helpless to rescue her. To Zoro and Tsuru's surprise, Kiku grabs a resting katana, and chases after the gazelle human.

With his running abilities proving too great to match on foot, Kiku climbs atop Komachiyo to catch up. Realizing he must do the same, Luffy grapples onto Komachiyo, displaying his Gomu Gomu no Mi power before Tsuru and Kiku.

Zoro hitches along as they shoot off and board the giant dog.
