Kyuuketsune
The Kyuuketsune clan uses a bloodline limit called 'konkihiru' (( literally meaning energy leech'. This clan is for the most part hated amongst its village for there way of 'leeching' chakra from the opponent, or whomever is around for that matter. The users of this bloodline have enlarges canine teeth which they use to bite into another shinobi's chakra network. From there they can drain the person of there chakra and adding it to there own. People of the Kyuuketsune clan have been known to use jutsu's while draining some ones chakra, but using the hosts chakra to power the jutsu opposed to there own. People from this clan have also been known to be attracted to chakra of others with bloodline limits and hosts of demons saying that there chakra 'tastes better'. When some one using Konkihiru and they run dangerously low on chakra they have been known to go into and enraged frenzy, putting all there energy (( still unknown where this energy comes from seeing that they are low on chakra )) into draining the nearest person of there chakra. As the user grows there control over this furry grows but some in the clan have been known to use jutsu specifily made to burn chakra so they can put themselves into this state of rage.
