Parallel Existence

Parallel Existence (並列存在) is an Extra Skill created by Velgrynd which has seen use in the series by other characters.

Abilities
It allows the user to split their consciousness and give flesh to independent alter egos of themself, referred to as an Other Body (別身体).

Notable differences between Parallel Existence and the Body Double Skill:
 * Each Other Body can be considered the main body and will continue to exist even after the original body of the user dies. All Other Bodies are autonomous, able to take independent action and do not share thoughts and awareness; only upon their dismissal or destruction their individual experiences are assimilated by the user's remaining body or bodies.
 * All Other Bodies are actively connected to the magic pool of the user, allowing energy to be shared freely from anywhere. Use of Ultimate Skills is not restricted, either. The only notable drawback is how many Other Bodies can be active at once while sparing energy for other purposes. Each Other Body has an initial energy cost of 10%; this is essentially a collateral, an energy maintenance cost. The full amount will return to the user upon undoing the Other Body, assuming it has not sustained damage.

Some users are also able to effectively recreate the effects of the Body Double Skill, creating Body Double-like Other Bodies, which are weaker energy-wise and cannot be considered the main body, but are still autonomous and have a much lower maintenance cost, if at all. If the user has the Thought Communication skill, their Other Bodies can communicate mentally and share information, assuming they are within the skill's range.
