is bleach episode 39 filler?

Approaching Ichigo Kurosaki as he lies bleeding on the ground after being grievously wounded by 11th Division Captain Kenpachi Zaraki, Zangetsu inquires if he wishes to fight, win, or survive. When Ichigo decides that he wants to win, Zangetsu claims to not hear him, prompting Ichigo to elaborate that simply fighting or surviving have no meaning on their own before proclaiming that he wants to win as he grips his broken Shikai, Zangetsu.

As he kneels before Ichigo, Zangetsu acknowledges this and declares that he will take Ichigo there as his cape flares outward and engulfs Ichigo, transporting him to his inner world, where he finds himself standing on the side of a skyscraper.
