That Is the Power of Life is the 415th chapter of Hiro Mashima's Fairy Tail. The dangers posed by Face and Acnologia are averted thanks to the Dragons. But they reveal that they had been killed by Acnologia long ago, only their souls surviving inside their children. They bid their wards farewell and depart in a blaze of light. Elsewhere, Natsu is comforted by Igneel's fading spirit and swears that he will defeat Acnologia someday.
