[n-a] Karui (S): Sword Challenge

It happened frequently to me in battle that when I used Karui (S)'s skill 'Sword Challenge' it gave the 5 points of permanent extra damage to the opponent even though Karui did more damage. Sometimes it gave both to Karui and the opponent even when the opponent did not do the same amount of damage.

I also noticed that her skill 'Karui Lariat' deals damage even when she dies (the second turn if its effect . Maybe it's on purpose, maybe not.

Please fix this. She is a weak character even without this glitch.
