Uraurashima
Uraurashima, better known as Reverse Urashima, is an English manga fighter and member of the Fractured Fairy Tales. His whole gimmick revolves around a twisted take on the classic Urashima Tarou tale.
During the tournament's Semi-Finals, he faces off against Kurama. His strategy is pretty clever—he convinces Kurama that he's being forced to fight, then whips out the Idunn Box (a reverse treasure chest) with the goal of regressing Kurama back into infancy so he can finish him off. The plan backfires spectacularly though. The magic works too well and brings out Kurama's true form: the ruthless Yoko demon thief. At that point, Yoko decides torture sounds like a fun way to extract the box's secrets from him.
Before Uraurashima can spill anything useful, Shishiwakamaru ends the fight by throwing his sword through the barrier, piercing Uraurashima in the neck and killing him instantly.
The real kicker? He turns out to have been a lesser demon in disguise the whole time, which explains how he pulled off that whole magical reversal thing in the first place.
