Glad to see her technique had worked, she leaped over to the other wall, making sure her connection to the wall would reinitialize when she landed on the other side. Rikku headed to where Yakuza and Eriu were currently, knowing full well her technique wouldn't hold the ordinarily rampaging beast forever. They'd have to kill it now, or at least soon.
She was worried, however, that Yakuza wouldn't be able to hold on to Eriu for very long, but maybe the kid had more muscle on him than she gave him credit. Although, she'd rather not test things either way. Still, they were busy, leaving the beast to be dealt with, so as she closed in on the two as they held on to the wall, she'd kneel down to see how they were doing, whispering to them as she knelt down.
"How are you guys holding up?"
She'd wait on their reply, and if they seemed to be doing well on their own, she'd leave them for now and eliminate their beastly companion. After all, it was completely immobile, finishing it off wouldn't be a problem. However, if Yakuza needed a hand she'd take over holding on to Eriu, and allow Yakuza to take care of the creature. That or, they'd make a beeline for the other end, where supposed safety awaited them.
