Miroku :

Miroku is a lecherous monk. He asks every pretty woman he meets if she'll bear his child. Though this sounds quite ridiculous, Miroku has a good reason to ask. He, his grandfather, and his father have been cursed by Naraku with what is called a kazaana [Air Void]. In the palm of his right hand, Miroku uses a monk's seal to keep the Air Void in his hand from sucking in everything around him (it's like a black hole). The bad part of this curse is that the Air Void will eventually suck him in as well, just as it did to his father and grandfather. Thus, Miroku has to continue his family's line so that if he fails to kill Naraku, thus lifting the curse, his son will have to take on the job. He meets up with Kagome and Inuyasha early on in the series. Finding that he and Inuyasha (as well as Sango, who joins the Yasha gang last) have the same purpose (finding the Shikon shards and killing Naraku), he helps as best he can whenever they fight Naraku's evil forces.

Personality:

Miroku seems superfluous and flaky, but he constantly worries about the Air Void in his hand, and feels that time is running out. He has a good sense of humor, cares for the others in the Yasha gang, and makes great sacrifices if he feels it will help them.

Skills:

Though his kazaana (AKA 'toraeza') is his most powerful weapon, he sometimes cannot use it due to Naraku's poisonous insects (Saimyoushou [Hell's Insects]), which sometimes pop up to willingly get sucked into the Air Void, stinging Miroku as they enter. However, he also has some significant holy powers, which he can use to protect the others by making a invisible shell over them, and his shakujou [monk's staff] is a pretty good holy weapon.
