It's taken me a while, but I guess I have the time so I'll review the character you sent me via PM.

[hider=Shiro Konton Review]
Kekkai Genkai/Jutsu:
I've seen blood release before, and so far this is one of the stronger variants. And quite frankly, this is the biggest issue. Not only is it versatile, it is also powerful in all the departments it dabbles in. I would suggest, personally, that it can just be utilized as a weapon itself. The acidic, explosive, or defensive properties of it make it too strong for a genin to possess. We had a blood release user before that could make blood acidic or explosive, and he was S-ranked. So tone down the KG (and the consequent jutsu).

Also on the note of the KG, since you put it as the chakra release as well, does this mean that she cannot use other jutsu or is she limited to only her blood release?

Traits/Skills:
I don't have any real issues with the skills, but I don't think a genin should have Killing Intent. I believe the other GMs would agree with that as well, so I would suggest removal. Besides, a genin doesn't need it nor is a genin terrifying enough to use it. :p

History/Personality:
Both are a bit thin, and I would prefer if they were improved. Though that isn't a requirement, I think it would be better if the character was more fleshed out and had more detail.

Fix those up and I'll take a look at it again.
