The reaitsu system, it is used to determine how much power your attacks have. Lets say I and Takumi are fighting, I have 50 Reaitsu at the moment and Takumi has 30, 50-30= 20 Takumi can do a max of 20 damage to my hp while 30-50=0 meaning I can do a max of 50 damage to Takumi's hp. The only way to get Reaitsu eeffectivly immdeaditaly is to start good threads in training. You cannot ask for how much you get, the admins will decide how much you are able to get. As you use techniques your Reaitsu decreases out of its max a bit and also f you have shikai,bankai etc... your reaitsu gets bigger you may also post trainigns to improve the amount of reaitsu taken and given to you for things like this. and let's say that my Battle with Takumi is done and I used all my Reaitsu, then my Reaitsu shall stay like that for the whole day. The next day it shall all be recovered to its max, but alternatively you can use your coins to restore you Reaitsu (1 Coin = 1 Reaitsu) but notify the admins if you want to resotre your reaitsu by coins.
