Fissures of Fire

 is a technique of Shūsuke Amagai's Zanpakutō, Raika.

Description
As Amagai draws his sword straight back, his Shikai begins to glow red hot, forming a ball of fire within the hook of the blade. Raising the sword upwards, Amagai swings the blade around himself in a circular fashion before slamming the blade into the ground. Upon striking the ground, a large geyser of flames, many times taller than Amagai himself, rises from the ground, consuming anything caught within it. Despite this attack's large size and apparent power, Ichigo Kurosaki had no problem defending himself from it with his Shikai.
