is one piece episode 481 filler?

Whitebeard's pirate coalition celebrate their victory while the Marines are horrified and angered that Ace was freed. With Ace now glowing with fire and free-falling with Luffy, Ivankov cries with joy that the latter's father would be happy.

Hancock praises Luffy hoping he will have a happy ending with here and wants to marry him after leaving Marineford. Helmeppo is in shock while Koby accepts that Luffy is just as he is.
