I crunched about 500 kut-ku in unite, but none were destroyed this totally! Special frontier wizardry again!

I worked out once using a weapon calculator that it is possible (just) to 1 shot a kut ku in unite. If you use art of unsheathing, king atillart sword and adrenaline, and hit it with a full charge in the stomach. It should work, but I've never pulled it off.
