Storm Release: Olympian's Wrath

This is Kenno Sagii's most powerful original technique, as well as one of his most risky. After weaving the needed series of hand signals, the user gathers Water Release chakra in one hand and Lightning Release chakra in the other. The user then clasps their hands together to create Storm Release chakra. The user channels the chakra throughout their body and stimulates their tenketsu to send all of their chakra to the user hands. The user is then covered by a layer of storm chakra all over their body. Shortly afterward, a large sphere of whitish-blue energy erupts from the user and spreads out at a incredible rate in a large radius, tearing almost everything that comes in contact with it to ashes. This technique can also generate raging supercells above and make large quantities of water erupt from under the ground and cause violent reactions to pre-existing water.

However, this technique requires nearly all the chakra the user has. That being said, after one use, the user is instantly drained of much of their chakra and are unable to use any other jutsu. This attack also attacks the user's skin, muscles, and tenketsu. After this technique is over, the user suffers from severe muscle burning similar to fever, burning of the skin in some areas, and tenketsu exhaustion. If the user is not medically treated immediately, they will die. The effects will lessen if less power is used, but the burning will remain.

Trivia
This technique, its name, and its effects are derived from the Olympic gods of Greek lore. It is more focused on Zeus and Poseidon, two the oldest and most powerful Olympic gods as well as brothers.
