Blood Geist: Blood Cataclysm

A highly devastating technique within the Blood Geist series, it can change entire landscapes in seconds.

By conjuring centuries of blood from the soil, Yosoi can tap into the natural energy of the Earth and its atmosphere, causing a reaction within the jetsteam. This reaction causes numerous tornadoes to form for miles, devestating anything within their path, while crushing anything that enters them. The rapid rotation of these tornadoes and typhoons induce extreme lighting strikes within its area of effect. Massive resevoirs of blood erupt from the ground and form cyclones as they flood the area. It also rains blood capable of eating through steel during this period, while anything within the effective area of this technique will have their chakra systematically drained while their blood starts heating up to the point of it boiling before it exits their body and contributes to the technique. On command, Yosoi can trigger a massive explosion of boiling red blood.

Kerryūgan and Blood Release wielders seemed to be unaffected by the blood boiling aspect of the technique.
