(Fūton: Kū Sora ) – Wind Style: Spirit Void
Type: Defensive/Supplementary
Rank: S
Range: Short - Long
Chakra: 40 (-10 each time it's used)
Damage: N/A
Description: A technique simple in nature, but extremely effective, Spirit Void was one of Roy Mustang's own creation. Versed in it's defensive capabilities, the jutsu begins once the user channels and sends a a copious amount of his chakra into the skies above, ranging from short to long range all around. Following this ensues an unpredictable and quick movement of visible Wind in the skies, continuously flowing and swerving, seemingly without purpose before heading downwards and disappearing into nothing. However, purely through the users will (or through hand/leg/general body movement for cosmetics) the user can harness the wind power to create a defence which leaves the user unharmed. When seeing an incoming attack, through will the user controls the wind around the jutsu and forms it around the incoming attack, where the Wind would then slices/cut through it and/or blows it away, depending on the nature of the attack. For example, an Earthen projectile could be sliced and cut until it is no longer a danger, whereas a Water attack would be blown back. Of course when being used to defend, the Wind once again becomes visible to the naked eye, showing a green-ish hue. Although the process at the beginning appears to take time, when used within the same time frame of an incoming attack, the defense would be able to work just as well as any other Wind jutsu. This technique will only activate against techniques that it can neutralize (as an S-Rank Wind) and it will only activate once per turn and it cannot be stacked with other automatic defense jutsus.
~ Can only be taught by Erzo. This jutsu can be used twice, lasting four turns each time. Cannot be used consecutively, but instead with a one turn wait after four turns are up/the jutsu is deactivated. Although the user can manipulate this jutsu through will, thus allowing himself to remain unoccupied and free to perform other techniques, when used to defend against other techniques it will still count as one of the three allocated moves per turn.
(Ototon: Jentoruekō) - Sound Release: Gentle Echo
Type: Defensive/Supplementary
Rank: S
Range: Short - Long
Chakra Cost: 40
Damage: N/A
Description: A sound jutsu versed in it's defensive abilities, Gentle Echo allows the user protection from specific techniques. The user must first focus on the vibrational frequency of the opposing jutsu, having done that then releases Sound either through a clap, or via the mouth, creating a sound of equal frequency, mimicking the incoming form(s) of energy/chakra. By altering it's vibrational frequency and mimicking that of the opponents jutsu, the sound is able to displace the incoming form of energy, allowing the two to clash and nullify each other, leaving nothing behind but dispersed energy. This jutsu is able to defend against Wind/Fire/Lightning, and other elements of that nature, and anything which is Energy-based, as long as it is created using chakra (so can't use this against SM) of equal rank. But it would not be able to handle the physical attributes that come with Water/Earth based techniques.
~ Can only be taught by Erzo and is usable three times per battle, with a turn between each usage. Within the same turn, the user is not able to use other Sound techniques of S-rank and higher. It can only nullify up to A-rank wind due to the elemental disadvantage.
(Ototon: Heka no Kaiteki ) - Sound Release: Heka's Comfort
Type: Defence/Supplementary
Rank: B
Range: Short - Long (depends on jutsu its backing)
Chakra Cost: 20
Damage Points: N/A
Description: Heka's Comfort is a jutsu versed in its supplement use of supporting other defensive and supplementary jutsus. Not having any power or use by itself, it's a jutsu used alongside another sound jutsu, allowing its use to be instant, and within the same time frame. It works by the release of sound waves which mimic the properties/abilities of the previously used jutsu, allowing this jutsu to act as back up and further strength, which is clearly shown as it allows the previously used sound jutsu to work against jutsus 1 rank higher than their usual limit. However, as mentioned, this by no means can do any damage by itself, nor when used alongside Sound jutsus which are able to deal damage. It's uses are purely supplementary and for defence purposes and thus can only be used alongside jutsus which are of the same type.
~ Can only be taught by Erzo. Can only be used 4 times with a turn wait after each usage.
(Fūton/Katon: Aiorosu `Ikari ) - Wind/Fire Release: Aeolus' Wrath
Type:Attack
Rank: A
Range:Short - Long
Chakra Cost: 30
Damage Points: 60
Description: The user releases their Wind chakra from mouth or through hand movements (short ranged release when used in either of these forms), or from the skies above. This releases what appears to be little light-green rain drops (ranging from 3-10 inches in size) which are extremely sharp and naturally fast due to the nature of Wind, and the way they are shaped, being extremely slimline. After these little rain-drops of Wind form, the user would add his Fire chakra into them, causing them to become extremely heated. Their colour would change into one extremely similar to the colour given off by '( Katon: Onidōrō ) - Fire Release: Demon Lantern', giving off a yellowish colour as the light-green and red from the Fire chakra mix together. Upon colliding with any other jutsu, regardless of whether it's Energy, or Matter based, the Rain drops would explode outward, releasing heated Wind which has blowing force with the addition of scalding effects. The jutsu is designed to always explode in the direction of the point of contact with the foreign chakra. Due to their size, each outburst of heated Wind would be quite small but since they always rain down/travel as a group of heated wind 'raindrops' the damage done is nothing but. Moreover, the addition of Fire also allows the jutsu to travel towards bodies of heat which do not belong to the user, making this a double edged sword if used in a fight alongside allies. Moreover, upon the creation of the Wind, a screeching and deafening sound can be heard, making the source of it's creation quite obvious. The screech can not do much damage other than causing a slight discomfort, unless coupled with another jutsu which can amplify it. The user can avoid the discomfort caused by sending chakra to his ears moments before the use of this jutsu.
~ Can only be taught by Erzo. Usable three times per battle. After each usage the user must wait a turn before being able to use again.
