is one piece episode 478 filler?

Luffy has restored his strength, just as the new executioners are ready. Ivankov confronts Luffy in that the energy hormones do not repair the damage he has taken, but Luffy claims he "will not fall again".

The two executioners prepare themselves to execute Ace. Ivankov tries to calm Luffy down, but is unable to do so, deciding he will protect a now rushing-Luffy.

Luffy is halted by multiple Marines, which he defeats, but to no stopping.
