Custom Demon ~ Kentai

Name:Kentai

Effect: When Suki's health is at Crisis level her body heals it's self and she comes into a demon stage. She has blck eye's and grows fangs.

Downsides: Suki can't hold this for long so soon after she faints and will be out for a long time.. When she can take control of the demon stage she can stay demon for a bit longer.

History:Kentai attacked Ame when Suki was born. Her father, the Kage of the village sealed it inside Suki. He died from the jutsu and her mother thought of Suki as the demon. Suki's mother still couldn't kill her so she sent her away to Konoha to live with adoptive parent's. Suki's adoptive parent's could not tell Suki about the demon or who her parent's really were.

Description: Kentai has four tails. Two blue and two red. Half his body is black and the other half is white. He looks like a sort of lion.

Denied, sorry but for one parents that worked on a farm wouldn't be strong enough to seal a demon unless they were ninja, and even if they were it is unlikely that ninja strong enough to seal a demon would work on a farm.
Two because the downsides happen for pretty much everything, jutsus, kekkei genkais, etc etc.
Three, because the Effects can be initiated with simple training and it is unlikely that that is the effect of a demon.

This better???
