is one piece episode 35 filler?

Chew, Kuroobi and Hatchan investigate reports of a flying ship, finding the ship's wreckage in the paddy field. They confront Luffy, watching him taking a walk in the area.

Meanwhile, Nojiko tells the other members of the crew about Nami's past. Both were raised in the outskirts of Cocoyasi Village by their adoptive mother, Bell-mère, who farmed mikan to survive.

Being a low-income family, Nami often stole books from a local bookstore to support her passion in cartography, Bell-mère fed Nojiko and Nami while eating only mikans herself, and Nami received only hand-me-down clothing from Nojiko.
