Solo Era

Solo Era (のみ時代, Nomi Jidai) is a type of Caster Magic and Lost Magic involving restricting and limiting one's own magical power.

Description
Solo Era is an ancient and unique magic in which a certain process must be performed before it can be put into use. First the user must separate their inner magic from their physical bodies, creating a new entity of magic in their image. They then lock this entity within themselves, with a protective barrier around it, making it seem like they have no magic at all from outside detection. The user can then open this barrier, thereby releasing their magic. Normally, this would cause their magic to flow out, and they would eventually die, but the user's magic entity contains it in a white sphere around the user. The entity appears behind the user as it does this, with it's hands holding the white sphere, but only the user can see it like this. The user can then manipulate their Eternano in a much more refined form.
