Fire Sensei (Ninja 火災マスター) helped Sensei create the sport "Card-Jitsu:Fire". He is Sensei's long lost brother. He had disappeared in 1999 and had been missing for 10 years. He was found a week before the announcement of Card-Jitsu: Fire. Fire Sensei's appearance looks much like his younger brother, Sensei. He has the same features except there is a scar on his face to represent the differences. The main difference is that Fire Sensei wears his fire robes. Fire Sensei usually stays in the Fire Dojo, and usually visits his home-land, Fire Island.
