Re: ★iSengoku - Kaene
Fire once used against water will conjure mist and sometimes steam.
Fire once used against wind will most likely either be exterminated or combine with the wind depending on the rank i suppose.
Fire once used against rock will merely make the rock harder and heated which in some cases will transform the rock into lava.
Fire once used against lightning can alter weather conditions in some cases.
Hello Onii! I will be taking over your fire training
Not onto what my Sensei asked you last. I believe she wanted to know what would happen if the other basic elements were applied in combination with fire. For example, if fire was used in combination with water, it would either evaporate it completely, creating a mist of steam as you described. Or, one could use a low enough ranking fire technique to bring the water to a boil, which would be scolding hot, and have severe effects on touch. This is not a popular combination, but its definitely a cool one. If I used fire release, I'd surely try it myself.
When Fire and Wind are combined, the wind will act as a fuel for the fire and cause it to grow larger. Though it is never a good thing to have too much oxygen (wind) otherwise the flame will burn out. When released from the same general direction, both elements supplement each other. However, when facing against one another, the wind technique wouldn't fuel the fire, it would in fact weaken it on the clash (Depending on rank interaction of course) and continue (Or cancel out).
Similar to water, fire can be used to heat up earthen structures, making them scolding hot to the touch, or they can be burned with such intensity that they would turn completely molten, thus making what we like to call 'psuedo-lava'. There is one earth style technique that revolves around the user creating a tunnel under ground and then spewing fire into it. The traveling fire melts the minerals in the ground as it heats them up, slowly but surely turning them into molten earth, (Psuedo-Lava). In some other cases, when facing against each other, there are certain fire techniques that back a solid enough punch, to break earth apart, as seen with some of Sasuke's fire dragon ball techniques.
As for Fire and Lightning, fire can't directly be used against lightning to produce stormy conditions. They are both intangible elements so they phase through each other. Fire release can be used to heat the atmosphere by releasing long-range fire projectile techniques that may set up the conditions for kirin, but you'll learn that later, both in fire and lightning training. (Mainly in your lightning training.)
If you have any questions please ask away! I am here to answer everything I can. ^_^
Afterwards I want you to perform a battle combination using some of the fire technique(s) you've learned thus far. Pretend like this is an official fight, follow all rules and restrictions. There will be a clone of myself, long range away from you. Make your move!
