Too bad, we're doing this one by one. First up
(Ototon: Naiteki Ne no Jutsu) - Sound Release: Inner Sonar Skill
Rank: D
Type: Supplementary
Range: Short-Long
Chakra Cost: 10 (-1 per turn)
Damage Points: N/A
Description: The user will enhance their hearing by infusing his ears with sound chakra. Then, by utilizing chakra and enfacing his lungs, the user will be able to control the frequency and intensity of the sound emitted from his simple breathing. This low frequency, inaudible sound is passively emitted and has no effect other than emerging from him and bouncing off of objects. Using the enhanced hearing, the user is able to know where everything is around them, effectively creating a sonar effect through the rebound and reflection of sound waves. The hearing and the sonar effect is precise enough so that one can effectively use it to substitute one's vision in battle if needed. Despite being very effective, specially if the user has any of his other senses hindered, it also leaves the user vulnerable to sound genjutsu or sound attacks which will be much more drastic in its effects.
Note: Lasts 6 turns
Okay, with this one, you activate it once at the beginning of your turn, and then it lasts until you release it or until 6 turns are over, whichever is shorter. With this, you can periodically get a reading of everything around you, by the sound waves bouncing off of objects and returning back to you. Problem is, if the object is able to absorb the sound waves, you'll get a distorted reading, or no reading at all. If you're relying on this jutsu alone for a way to see, then it's the same as being "blind" higher than mid-range because it will take a bit longer for the waves to bounce back. Granted, this doesnt take a lengthy amount of time but it's something to keep in mind. With that being said, it works marvelously in a mist, or even in a dust screen. It works underground, above ground to sense underground, in forests, inside a room, etc etc. The advanced version that Mugi created is so much better, able to tune out specific sounds as well as hear things as small as ants walking. When it's active, you gain a x2 tracking boost as well.
Lastly, beware of the enhanced sound, as you'd be extra susceptible to loud noises. Similar to how Kiba was extra susceptible to farts.
