Setsuna deflected Calen's quip with a slight wave of his hand, the other already holding up Taro. Man was he heavy. Feeling a slight twinge of respect for Calen being able to carry three people down with his semblance, there was no way that he couldn't at least keep Taro safe. Pulling his sword out from it's place on his hip, he shuffled the deadweight on his left shoulder and charged up, ready to rush straight in and wipe the path clean. "When I go pink-reddish, wait for me to clear the path, then rush through the gap. I'll stay behind you guys and cover your backside, since Calen has the light."
He stayed still for a few more moments, then abruptly surged forward, his body and aura turning the aforementioned color, disemboweling everything that jumped in his face with his increased speed. He wasn't sure if the light coming from his body was attracting the Grimm; if it was, he was a better target, thus hopefully keeping the others safe. Slicing through even more of the endless horde, he hoped the others were already moving so he could retreat safely.
