Air void!

The kind of thing you'll only see in Inuyasha: a monk with a black hole in his right palm. The subtitles translate it as "air void," but it acts more like a bottomless gravity well. He can use it to suck up youkai by the zillions, and in this cel it looks like he's just about to switch on the vacuum.
