Devil Swarm Magic

Devil Swarm Magic(魔集の魔法, Mashū no Mahō) Is a Caster Magic, Lost Magic, and Subspecies Magic of Magic Eater that allows the user to create carnivorus mouths from the users own body or in forms of balls of energy that allows them to absorb Eternano energy and negate spell effects.

Description
It is said that to create a subspecies of a Lost Magic would take decades, and the user has certainly succeeded. When manifesting the magic, the user shapes and channels their eternano utilizing the basic concept of Shape Transformation; compressing and condensing their eternano and reversing its polarity so that it is capable of consuming opposing sources of eternano, so to speak. Using Shape Transformation, the compressed eternano takes the form of a ball of pure magical energy, which actually reveals a giant, all-devouring maw. Interestingly, when in motion, the maw loses the ability to consume opposing sources of eternano, instead exchanging it for consuming the damage and effects of opposing spells; essentially leaving the spells launched at the user positively harmless to the user—in a manner very akin to that of its parent magic, as well of Wave. The attack will then proceed to consume the magic, regardless of the opponent's actions, until it is completely eaten, and form into a ball, which harmlessly bursts after a few seconds, the energy emitted used to fuel its motion. In addition, it is geared towards consuming the magic of the opponent. However, this isn't the full extent of it's ability; it is said that the spell is "saving" magic from the user's opponent, the magic is thankful to Devil Swarm for being "saved" and they grant their powers to the magic almost limitlessly; drastically boosting its offensive powers. Lastly, the user is capable of producing mouths all over their body in order to launch the spell; or even concentrate its effects there as to turn them into a human deflector shield. One of the greatest advantages of this technique is that it will only aim for the intended opponent, and nothing else, leaving anything unnecessary unharmed.
