is one piece episode 990 filler?

A mysterious masked figure runs through the halls, excited to meet Luffy. He is chased by the Beasts Pirates after they see him.

He crosses through several rooms, including the one where Kid is fighting some of the Beasts Pirates. Meanwhile, Ulti checks on her brother Page One.

She again throws a fit in front of him, remembering how she rode on Page One's back down the staircase. She then confronts Luffy, being told that he is a pirate intruder.

They immediately get into a fight and they headbutt each other, each attempting to knock the other down.
