is jujutsu kaisen episode 45 filler?

Todo and Yuji fight Mahito together. Boogie Woogie turns the battle into a two-man assault where neither Mahito nor the fighters themselves know who's attacking from where.

Todo swaps positions constantly, creating openings that Yuji fills with Black Flash. Mahito escalates to Soul Multiplicity and Body Repel, reshaping himself into increasingly dangerous forms.

The fight is the peak of Todo and Yuji's partnership — two friends who met hours ago fighting like they've trained together for years.
