【Fighting style】
Conservative. He's not particularly fond of fighting, however all males part of the Ooi bloodline must. Meaning he will play defensive, although when in a rage his true skill shows. Most blinded by rage tend to stray from their skills and fall back on more instinctive reactions. Douzen, however, hones all the skills and manages to remain sane and collective on the outside, while raising Hell inside.[/quote]

Hones all the skills? What does that mean? Does he have all the skills in the world? 

[quote=@Xuna]Jutsu name: Hell's Wrath
Rank: B
Range: 1 yard circumference around user
Description: After placing one's hand on the ground, the User channels their energy through the Earth, Sapping the the life force around a small area. After doing such, the user pulls his/her hand from the earth with it's energy flowing around the palm. The user then combines that energy with the fire elemental affinity to create a small ball of fire. Once the ball comes in contact with a target, there is a small explosion that occurs that may inflict more internal damage. This may also knock the target back a few feet.[/quote]

What energy is he absorbing? Measuring system for power in Naruto is Chakra, and you can't absorb energy from the environment without senjutsu, and it doesn't work that way either. However that aside, it's essentially a fire ball that does an explosion. The fact that it makes internal damage needs to be explained a little.

[quote=@Xuna]Jutsu name: Hell Hound
Rank: C
Range: 50 yards
Description: Douzen kneels to the ground and cuffs his mouth with both hands to perform this jutsu. He releases fire chakra from the mouth in the shape of a flaming wolf. The wolf charges forward to collide with the target causing a semi-small explosion that may leave 2-3rd degree burns.[/quote] 

I'm okay with this, just as long as 3rd degree burns don't suddenly happen unless it's a direct hit, and it's only at the most exposed parts. I'd say 2nd degree burns most of the time though considering it's only C rank.

You're going to have to link all the jutsu to the Narutopedia site. I have no idea what half of these do. 


[quote=@Xuna]【History】  

Museigan, however, would not let his son die with him. He filled a book with all his teachings and had asked Atemi to give it to Douzen. He had always seen great potential in his son and insisted that he become a ninja. Atemi also possessed the same feelings about the boy, so she obeyed her husband and handed the book over as promised. Douzen absorbed the information and translated it into action beautifully as a child, but lost a lot of that aggression and drive after getting over his father. Atemi never let him stray from the ninja way. after observing the boy's behavior, she knew the case and decided to put him through ninja school. [/quote]

This last paragraph is essentially the only part about your character's history. The entire thing is about his dead dad. That's somewhat irrelevant to the CHARACTER'S History. We want to know what he lived, not what his deceased father lived. I'm not sure what you were aiming for here.
