the tree-sucky thing (<-- bad with names) that Kurama used on ani-Tugoro, that's the kinda toture a fan lives for. : )

though Touya's ice-sword-knife was pretty spiffy (not the most original, but hell.)

Jin's wind tunnel! >w< spiffiness, there aren't enough air-based characters in anime, and when there are, usually they look like some angel or something, and have this whole "graceful" look, while Togashi goes right in the oppposite direction and basically says "fudge standards, I'm coming up with my own character!" >w< too much genius.
