This technique concentrates Kurumi’s energy through her hand to project a ray of heat which would detonate with great force, producing situated explosions with a great deal of precision. This technique is extremely effective and very destructive, capable of being used at close and long-range; it can completely disintegrate hill-sized boulders and instantaneously evaporate large bodies of water with ease. With training Kurumi has learned to employ it to burn things without setting off an explosion, similar to a lens focusing sunlight. This is probably due to the energy being entirely focused into creating the explosion, without wasting energy maintaining a long-range jet of flame. However, the technique has the potential to be just as hazardous to Kurumi as it can be to her surroundings, so she has to be very careful in its use.
