is bleach episode 218 filler?

With Charlotte Chuhlhourne defeated at the hands of 5th Seat Yumichika Ayasegawa, his Rosa Blanca fades away. The fully bloomed flowers from Yumichika's Ruri'iro Kujaku fall and Yumichika catches one in his palm.

After re-sealing his Zanpakutō, he bites the flower he caught, absorbing Chuhlhourne's Reiatsu. A near-death Chuhlhourne compliments Ayasegawa's technique, assuming it to be his Bankai.

Yumichika corrects him and explains the real name of his Zanpakutō to be Ruri'iro Kujaku. He tells him that his sword has a favorite color, sapphire and that it despises lavender.

As Fuji translates roughly into lavender, his sword hates the name.
