Almighty Shift

Sensō channels the power of four elements around him, preparing to ravage his surroundings. The sheer lethality of this technique is incomprehensible, reducing everything in a 6 kilometre radius around the centre to rubble.

Usage
The first stage of this attack is for Sensō to form hand seals before smashing his palms to the ground. The surrounding ground cracks and gives way, forming massive holes in the ground and even causing certain parts of the ground to sink into the bowels of the Earth. With the ground in tatters, Sensō proceeds to the next act.

The second stage is initiated by Sensō charging up a massive fireball in front of his mouth. Kneeling down, he spits the fireball into the ground. The massive gaps left in the ground by the first stage of the attack now become conduits to enable incredible fires to leap from underground to the surface, effectively creating miniature volcanoes. This leads to a savage firestorm engulfing the surrounding area.

The third stage of the attack involves Sensō blasting a massive jet of air around the battlefield, turning it into a swirling hurricane of fire. The Wind feeds the fires, making them grow to titanic proportions while causing a swirling jet of fiery devastation to wreak havoc around the epicentre, where Sensō stands. This move also makes storm clouds, cumulonimbus, to gather due to the intense temperatures generated by the firestorm.

To finish off the attack, the final fourth stage is initiated by Sensō. With the firestorm still swirling, Sensō raises both arms to the skies and channels lightning from above to mix with the firestorm. Now an inferno powered by lightning, the lightning savagely strikes from all angles, devastating the land and effectively killing anyone who survived the initial assault.

The unimaginable power of this attack was used by Sensō to defeat armies consisting of hundreds of thousands in mere minutes, further adding to his god-like status.
