Bat-Body Manipulation (バットボディの操作 Batto bodi no sōsa) Is an extremely powerful Caster Magic used by Jean-Jacques Mathieu De Tristan, as well as being the only one to have fully mastered it.

Description
The the body users of this magic, after a proper training, become formed by a group of a total of 1.000 of bats,capable of deconstructing and reconstructing himself at will, with his body maintaining within a constant unstable flux, as the multitude of 'bats' persistently rearrange themselves. This results in the users being able to change shape at will, and separate into countless bats, which is extremely useful to evade and confuse opponents as well as trap them and attack from all sides. The bats themselves are also able to change shape. They can be sharp blades which dive forward and slice the opponent with their wings, or they can form a magic circle on the ground for diverse attacks. A user can also use bats in his human form attached to his arms in the manner of blades. The only was to seriously damage the users of this Magic is to hit all of a users bat a once, since they can regenerate the ones that individually get destroyed. The bats, even if separated from the rest of the body of the user, he can still know where they are and what they are seeing. Thanks to this particular feature, they are also useful as spies to follow or observe a determinated person.

This magic is said to be a very particular and unusual form of the Darkness Magic which uses the control of ones direct body instead of manipulating only his internal Ethernano.

Effects
Shapeshifting: The user can dismember his body into a maximum of 1.000 bats as well as revert back in his human form

Bats-Shapeshifting: Due to their property of being a variation of the Darkness Magic, the bats can shapeshift into razor-like shapes or even magic circle-like one

Mind-Bat connection: As said before, the bats are still connected to the user even if they are far away from him, and they can spy someone or something

Regeneration of Bats: Should they be destroyed, the user, if he has still a good number of bats at his command, he can regenerate the dead ones up to reach 1.000 of bats again. If a good portion (At least 700) or all the bats are hit at once, the user will instead suffer seriously damage

Spells
Darkness Shredder (闇のシュレッダー Yami no の no particle * shureddā) Jean-Jacques extends his arm forward and launches a significant number of the bats that compose his body, while still retaining his human form, at his opponent. The speed at which these bats obtain while sent and their sheer number, result in tearing and ripping the opponent apart as they make contact with the bats razor-like shape.

Fang Tornado (牙のトルネード Kiba no torunēd) Jean-Jacques sets up a formation with the entirety of his 'bats' that surrounds the opponent from all direction, forming a circular seal. Immediatly after the bats start to do circular movements with extreme speed, forming a tornado of bats that drags the enemies up and tears them apart.
