Fairy Tail season 6 episode 10
Episode title: Tartaros Chapter, Prologue - The White Legacy
Natsu foiled the initial attempt on Michello's life, but now he has to battle Jackal, one of the Nine Demon Gates, to keep the former Magic Council member safe. It's a hard fight, especially since Jackal has the power to make anything he touches (or that touches him) explode.
