This hissatsu is the combination of two Fire Tornado. It is very similar to Double Tornado and Fire Tornado. Tsurugi Kyousuke asked Matsukaze Tenma to learn Fire Tornado DD with him in order to use it in the finals. They practiced the move at the Kasenjiki multiple days till it became night but never really succeeded in using the move properly.
First two people would spin around and create a fire which surrounds them by spinning, later both goes up and kick it towards the goal with one leg of each person. This technique only works if the two users sychronize each others movements.
In the GO series, when they performed the move in the Holy Road finale, the commentator said "It's the legendary shoot that Gouenji Shuuya used only once as a Japanese national!", talking about Fire Tornado DD, meaning that Gouenji has used it at least once when he played as a Japanese national with an unknown partner.
