Eiko was thrown by Cassius but stopped herself by stabbing her staff into the ground, she put the staff away and flipped towards him and was in a hand stand, she had her feet up to his face and started to kick at Cassius' face. 

( Jun has super strength as well )

Jun felt the attack to her knee, she didn't show any pain from Kori's attack, she let go of Edge and balled her free hand up into a fist and swung towards Kori's face with all her strength. 

( Jun's strength level is unknown )
