Highest Heaven Lightning Annihilation

The Highest Heaven Lightning Annihilation is Hiashi's most powerful long-ranged move, and, according to him, the most destructive Black Lightning technique in existence. He generates a titanic amount of the black electricity, causing it to surround his body. He then discharges it into the air, causing the atmosphere to become saturated with it. He then guides and shapes the lightning into several thunderbolts, which can be guided towards their targets. The lightning bolts are so concentrated that they have red edges, a testament to the technique's power. A single bolt has the power to completely decimate a small town. During the Datenshi War, Hiashi used it to break through Miyuki Murakami's Yata Armor. This alone is enough to demostrate the monstrous power of the technique.

The Highest Heaven Lightning Annihilation, however, has several drawbacks that limit severely its usefulness on the battlefield. Firstly, the technique has an extremely high chakra cost, so much so that Hiashi was hospitalized for three days after using it during the Datenshi War. It is important to note though, that Hiashi's chakra levels were severely depleted when he used it on that occasion.

A second drawback is that the intense buildup of lightning in and around the user's body can burn it, even when used properly. If it backfires, the technique can potentially kill its user.
