is bleach: thousand-year blood war (bleach: sennen kessen-hen) episode 25 filler?

As rain begins to fall across the replaced Seireitei, Yūshirō Shihōin leaps across the rubble with a large bundle of items held above his head and urges Yoruichi Shihōin to wait for him. Elsewhere, Kisuke Urahara draws a line in the mud with his cane before being approached by Hiyori Sarugaki, who questions why he is doing this instead of making preparations inside with the others.

In turn, Urahara asserts that he was preparing while waiting for Hiyori, Love Aikawa, Hachigen Ushōda, and Lisa Yadōmaru to get here.
