Another giant monster thingy, no problem. Making the tiger seal followed by the redirecting and concentration of her chakra, Michonne does several full spins, before using her right leg to kick the air. On the tip of boot, a small flame wpuld protrude from the edge, that single flame would become a ring of fire fluttering through the empty field onward towards it's target. The ring made contact sooner than expecting, burning the crab's exoskeleton to a crisp, but it left the crab unharmed. Smiling as she remade the tiger seal, she plants both feet on the dark green grass. From her location, a ring of fire would surround her, then two large walls spew and encase the crab it's own, larger ring. The circle of fire would prevent it from getting away, and it also would slowly cook the soft, meaty parts to a sizzling perfection.
Watching her bleak surroundings carefully, Michonne notices a man she should have killed earlier. Obviously startled by the sight, she grips a dagger and ties thing wire like strings through the base's hoop. With a twist, turn, and flick of the wrist, the dagger was sent to the man's chest and it circled around him, tying the wire in the process. Smiling a sheepish smile, she weaves the handseals [Snake → Dragon → Rabbit → Tiger], and spits a large flame of fire made from condensed chakra from earlier. The flames run along the wire and burn the Asura path to a pile of grey ashes, a fitting end.
After completing another technique, she sighs and turns around to a revolting sight. Not only does Michonne shriek, but she cringes at the sight of the rough looking man with no clothes. He even had piercings on his...nope, let's be child friendly. She forms the tiger seal and spews a stream of fire at his face, kill it with fire they said, and that's exactly what she did.
