Kristoph's strike was heavy, but slow. With ease, Eiro twisted his body out of the way and took hold of the other fighter's wrist. Using the momentum built during the dodge, Eiro pulled him forward, while hooking his own ankle onto Kristoph's.
Instead of doing the generally obvious thing and trying to struggle against this, Kristoph did the opposite; he further jumped into Eiro's pull and thus managed to take control of his own movement again. Eiro's hand was still tightly wrapped around his wrist, but that also meant that Eiro was in range and it would be hard for him to dodge out of the way. Kristoph leaned back and to the side, and pulled his leg upward to strike at Eiro's arm.
