Concealment Magic

Concealment Magic (隠蔽魔法, Inpei Mahō) is a Caster Magic and a type of Sealing Magic that deals with using sealing symbols if the user wishes to cover something up on their body, or covering other things. This magic is utilized by various mages, and is rather easy to use, making it a perfect basic spell learn-able by anyone with magic.

Description
There are certain levels of advancement that the user is able to learn with the right time put in to master them. The most basic level works like an invisibility cloak, where the object can't be seen, but it can still be felt and if someone were to put something on top of it, the visible item would be seemingly floating. Same thing goes for limbs, where if the user conceals their arm, nobody can see it, but it can still be felt and held by others.

The second level of this spell is the ability to conceal items that can't be seen nor felt, except for the user, making it a sneaky trick for magicians or anybody else who has use for it. The user can pick up the item all they want, whereas others won't be able to even sense it. Although someone with exceptional magical prowess, or someone who can sense magic signatures would be able to see the outline of such an item by seeing the outline of the magical signature on the item.

The last level deals mainly with body parts, and has the use of seals. For example, Velesko uses the magic to make his own spell which allows him to seemingly draw his wings into his back, sealing it with a purple magic circle. If you were to touch his back, you wouldn't feel his wings, but his back would be rather sensitive. Since the seal draws the limb into the body, and into their magical core, not even the user is able to feel the missing appendage.

Velesko's Spell

 * Wing Seal (翼封, Tsubasa Shīru): This command allows Velesko to fully seal his wings from feel and view. He keeps them like that most of the time so no one can see his fallen status (not that he cares much) but also to keep them out of the way, especially while fighting since most devils know how sensitive angels wings are. But around demons and vampires, he could care less.
