Savato, I am involved in moderation (Due to being a long time friend of Syn.) And currently I can point out a few quick things. 

- The first is that Body Flicker technique is denied. It's in the banned jutsu list. (Or to be more exact, you can have it, but never use it for battle.)
- Dead Soul technique is up in the air, due to being very similar to impure world resurrection. I leave final judgement on that to Syn, but I recommend that you at the very least limit the number of corpses you can use with this technique and to apply a timer to how long you can use it and how long it takes to prepare the corpse. 

- More info on his backstory is required before full acceptance. 
- Also, you will need to pick an alliance. We have had issues with 3rd party ninjas in the past and would prefer than characters have at least a side to be a part of. (If you have any objections, please contact me or Syn privately and tell us what you have planned if he is a 3rd party.)

Final Verdict: Your character looks fairly decent. I actually like your idea behind him and want to see more.
