is bleach episode 354 filler?

Using his newly developed Fullbring abilities, Ichigo Kurosaki uses his new blade to battle against Shūkurō Tsukishima. Ichigo attacks from above and, on the roof, Tsukishima casually raises his sword and blocks the incoming attack.

Determined not to give up, Ichigo releases a large amount of dark Reiatsu that emanates from his body and his blade. This takes Tsukishima by surprise and he is knocked back due to the increase in pressure.

Tsukishima's hand and lower arm are singed as a result of the attack.
