is bleach episode 64 filler?

As his alarm clock begins ringing in the morning, a startled Ichigo Kurosaki bolts upright in his bed and looks around his room before turning off the alarm while noting that he came home. Suddenly, as Ichigo moves forward to stand up, Isshin Kurosaki greets him and crashes feet-first through his open window into the floor, narrowly missing Ichigo, who looks at him in confusion.

Quickly recovering as the dust settles, Isshin praises Ichigo for improving his combat skill and reflexes to this extent.
