Like your vote man. In this battle, you're Akemi expertise will be needed (especially because I'm not hoping to get much vote in this shitty blog page)

But, telling you this, there's no instant kill button with Yuki. I've red some novels of Haruhi Suzumiya, and her enemies are not limited only to fellow artificial humans. She also faces a wide variety of enemies such as "foreign" threats, other different aliens, and rogue murderous time travelers.

Time manipulation won't work if both are inside Yuki's sealed space, where she has perfect control of virtually everything (seen in the videos)
