Yuri should have run. Blue light coalesced around Rukia's quaking fists as she stood her ground, glowering daggers at Yuri. There was no verbal response, save for one single word:

"Watera!"

A deluge of cold water rocketed forward from Rukia's palms as she thrust her hands forward at her dear, dear friend. Rukia didn't start water fights; she finished them.

At least she'd pulled her punches; instead of doing damage, all the spell would do was soak the target. And that target would be Yuri.
