Miroku

A Buddhist 'houshi,' or low-ranking, itinerant monk, Miroku traveled the countryside performing services such as exorcisms and youkai exterminations to earn his living.

He suffers from a hereditary curse originally inflicted upon his grandfather Miyatsu (also a Buddhist monk) by Naraku, who exploited Miyatsu's weakness for attractive women by taking the shape of one, and reflected one of Miyatsu's ofuda back to pierce the palm of his right hand (it appears to be his left hand in the English language manga where right and left are reversed). The hole in his hand became a kazaana (air void or "wind tunnel") which sucks in anything not nailed down, regardless of mass. Miroku uses the kazaana as a powerful weapon against youkai, but as he grows older, the kazaana grows inevitably larger, and if the curse is not broken by Naraku's death, it will grow too large to control and consume Miroku…
