is bleach episode 352 filler?

Riruka Dokugamine storms out of the Xcution Headquarters angrily. Once she is outside, she says that she doesn't want to look at Jackie's Fullbring, Dirty Boots.

Ichigo's fight with Jackie Tristan in the fish tank continues. Jackie says that she is noticing a pattern in Ichigo's fighting style.

She then explains her Fullbring's power to Ichigo. She says that the dirtier her boots become, the stronger she gets.

Riruka then comments on Jackie's Fullbring, saying that she doesn't want to be dirty and that she will remain clean and cute forever. Back in Ichigo's fight, Jackie tells him to stop messing around, and points out the flaws in his technique.
