The strongest Flare Release technique, the Flare Release: Energy Explosion Technique is a suicidal technique, used only when there are no other options. The users builds up chakra directly in the heart and then converts it into "flare energy", and finally releases the energy from their body in the form of maroon-colored lightning in all directions. The force exerted by this energy, combined with its high temperature (100,000 °F), means that there is almost no way to block this technique, even with Earth Release. This technique not only causes the user's heart to burst, but also cooks their insides, meaning no medical ninjutsu can save their life.
