is one piece episode 447 filler?

Luffy is furious, punching Blackbeard, making the latter fly into the wall. Blackbeard takes revenge and activates Kurouzu, making Luffy fly to his hand.

He then grabs the pirate captain and throws him into the ground, which causes blood to drip from his mouth, much to the surprise of Crocodile. Jinbe sees Luffy getting up, only to strike him down and talk about his main priority: Ace.

Blackbeard sees Luffy leave, telling him Skypiea and One Piece exists. Shortly after, Minotaurus comes from the level 3 staircase, punching the New Kama and the level 4 prisoners rioting down the stairs.
