'Well, that's not good.'
Jinju Ren could sense the incoming attacks about to pierce her backside, and she could sense that Rianna had decided to bust out one of the new aether arts that Zhen Liu had pulled out from the library for her.
The Kaijin Lord had reported to her and the others that something bad was brewing, and that they were going to need all the firepower they could muster to deal with it.
As such, Rianna wasn't the only one to receive an aether art.

Jinju Ren knew that attempting to dodge would probably prompt Rianna to try and follow up her attack with another weird arrow, while spinning around to deal with the attack would cost her time and may end with her getting shot anyways.
As such, she decided the best course of action was to concentrate her aether to her tailbone and summon and illusionary dragon tail that she then used to smack the arrow out of the air and attempt to smack Rianna with it.
