As Sans blasts a wall of fire between the fae and everyone else, Shima takes a last look at the scene before elbowing Rin and bolting, drawing from Yamantaka's strength and speed to tear through the aisles and leap over shelves, making his way toward the nearest exit. They put some good distance between themselves and the fae with no sign of pursuit, sprinting down hallways looking for familiar turns before Shima finds himself stumbling, his energy running dangerously low faster than expected. He's been practicing more with his familiar since his status as a double agent was revealed at home, but it hadn't really prepared him for the son of Satan borrowing an actively summoned Yamantaka, and wielding him with all his usual finesse of a thundering rhino.

"Your inexperience betrays you," Yamantaka grumbles to both Shima and Rin by extension. Which is real helpful commentary when Shima can feel his vision starting to swim.

The demon's presence begins to fade and Shima slows, grabbing onto the nearest wall-- "Oh crap--gonna. pass out.. Oku..mh...." --yeah, he's blacking out for a minute.
