is bleach episode 228 filler?

The members of the Shinigami Women's Association are shopping for new swimsuits. Lieutenant Nanao Ise holds up a purple bikini and wonders whether she's allowed to show off a bit or not.

Lieutenant Rangiku Matsumoto asks her why it's giving her such a hard time because she doesn't have any breasts to show off anyways. Nanao tells her to leave her alone.

Yoruichi Shihōin holds up an orange and green bikini with interest, saying she'll get it. Captain Suì-Fēng states that she'd expect that from Yoruichi, as she is so refined.
