This attack is very similar in structure to Screech Beta, as it also assumes the form of a mouth, but it is instead launched at the enemy as a projectile. It grinds through the floor, causing heavy destruction as it does so, while heading towards the enemy. It will explode at any time when it makes contact along its path. The majority of the attack features a black color surrounded by a purple aura. This attack was first demonstrated by Crona against Maka Albarn in their intial fight.
Black Dragon Resonance (Aerial)Edit
When used with the Black Dragon resonance technique, its power is drastically increased. In this circumstance, the attack doesn't employ its "mouth" to inflict damage but instead radically reduces its width, until the form is entirely flattened to create razor-sharp edges around its exterior. Due to the force at which the ability is launched, it easily slices apart the intended target and anything else in its path, before erupting in an enormous upward and similarly shaped explosion.
