This is going to be tough but I am a tournament champion. I will attack all simultaneously. I will distract fire demon with my hot poses, this will obviously cause him to heat up even more, hopefully so much he will explode. At the same time I shall scream out my famous battle cry which will cause temporary deafness in the other thug or thugs (not sure how many there are?) I will then viciously throw my ninja stars into their hearts. If fire demon doesn't explode I will attack with a flying side kick to his temple and follow with an amazing tornado kick to the right side of his head. "Aaaaaah, take that bad guys"
