Natsu gets more and more excited as the fight goes on, loving the feel on living on the edge. As his fire is absorbed, he pulls out 4 shuriken in both hands and just lets them go, so they go flying at you as you finish up with the barrier. Suddenly fire/lightning errupts around Natsu showing his excitement, with such excitement on his faces as he does two quick motions, he blasts to your left with his feet punching forwards releasing the force of the blazing lightning blade as you deal with the shuriken:
(Kaen rai ken) - Blazing lightning blade
Rank: S
Type: Attack
Range: Short-mid
Chakra Cost: 40
Damage Points: 80
Description: The user will gather a large amount of fire and lightning chakra around their fist. They will focus the lightning chakra to make it sharp, while they control the fire to surround the sharp shaped lightning. The user will then punch at their target, the lighting will cut what it comes into contact with (within reason, like not Forbidden ranked stuff) while the fire will be released in a huge burst blasting forwards to mid range burning what ever the user has hit with the lighting wrapped around the flames to shock and numb what ever it hits for 1 turn.
Note: useable twice
Note: No water jutsu in the same turn
(Kaen Rai Reiki) - Blazing Lightning Aura
Rank: A
Type: Attack/defend
Range: Short-Mid
Chakra Cost: 30
Damage Points: (+20 to taijutsu attacks)
Description: This is much like chidori nagashi. The user will focus their lighning chakra around their body (the lightning will not be touching the user) creating an aura of lightning. They will focus this chakra so that the lightning vibrates around their body moving faster and faster, without hurting them as it is controlled. As it moves faster, the lightning creates a mass of heat to produce flames that combine with the lightning moving around the users body. These flames wont be touching the user so he wont be burnt. This aura is used for close combat attacks and can be formed pretty quickly. When hitting something in this mode, the user will release the lightning through the object shocking it with a bolt of lightning and cause numbing/partial paralysis to living objects. Not only this, but the heat built up from the electircal current will burn the target too. And example of how this would work would be, when you go to punch an opponent, if they put their hand up to block it, you would hit their hand, shocking their hand dealing lightning damage, numb their hand from the shock for 1 turn and burn the targets hand.
Note: This mode can but used for up to a total of 4 turns in a battle.
Note: The user is more vulnerable to water attacks and would take +20 more damage if hit by a water jutsu.
Note: When this aura is active, the user can't use wind or water jutsu.
Note: This isn't using two elements at the same time, the lightning is generating the heat, i'm not creating the fire.
Note: Can't be used while in Sage mode (or similar) or with EIGs.
