Kazaana
	Miroku's grandfather Miyatsu battled Naraku and was cursed with the Kazaana (Wind Tunnel). Eventually Miroku's Grandfather was swallowed up by his own Wind Tunnel at which time the curse transferred to Miroku's father, and in turn was passed on to Miroku.
	Miroku has used the curse as a weapon, for when he removes his prayer beads and opens his right palm, anything in front of his hand will be sucked in. The technique is extremely powerful and has only one weakness, if Miroku absorbs any poison his body will feel the effects, therefore the Wind Tunnel is useless against Naraku's Saimyosho.
