Yukina leaped into combat, unsure of what just that red marking was. Whatever it was, however, it was dangerous. However, whatever power compelled it it would be no match for Sekkarou and it's ability to cut through magic - or so she hoped.
Bringing her own spear down, Yukina attempted to block the Knight of Honour infected naginata with Sekkarou before it could impale Asuna. Any portion touched by the spear's tip would be cut, for Knight of Honour ran Berserker's own Prana through it to assert it's control, and Sekkarou was the spear which cut all magic.
