Its been there for a while

E: jk that shit has been there for 2 years now. ive tried to get rid of it by putting it on my deactivate but it still plays the sound. I am lost and i dont even know what to do and how to fix it >:(

Go to your toribash folder, in here to the custom folder and delete the folder called Legendexpe.
Now go ingame and type /dl legendexpe
Now go into an online match and your kiai should be gone.
