Kitchen Zone was an offensive defence zone in Lynn's repertoire. Although the Lancer's pierce was fast, the rigid defensive manoeuvre has given her sufficient advantage to be able to deflect it. The only thing she regretted was choosing to evade instead of countering the attack. Due to the lack of experience she had given up the chance to break the Elite Lancer's weapon as she had done with the Swordsman.
Slaze, the Tyr Swordsman managed to pull his buddy away before the cook could rectify her mistake. Only after they had both put a considerable amount of distance away from Lynn, did they realise that she was not pursuing them or pressed for the next attack. This made Slaze believe that there was some limitation to the unbelievable chopping power she had presented just now.
