Realization

Reverse Sealing Magic (逆封印魔法 Gyakufūin Mahō, literal translation, Reverse Seal Magic) is a highly complex and powerful form of Lost Magic, which is also the opposite of sealing magics such as Susanoo Magic Seals, Amaterasu Magic Seals and Izanagi Magic Seals. It is used by Ankoku Joukei

Reverse Sealing Magic, unlike most magic, can have two distinct uses dependent on the situation it is used in. Although the ability remains exactly the same, which is "releasing the innate potential of anything in the world". This is done by seeping in his own magical power into an object, whether it be from one of his arrows, or his own body. Thus, once this has gone to the "will" of that object (must be animate in some way), it's magical potential is released. Albeit it is under complete control of Ankoku due to the object having his magical power. This is only until the potential is withered or it's own magical power is erupted. This can be applied readily in combat situations, as animate objects such as plants and many other organisms can be used to his advantage, as they can either be used as explosions or subordinates in combat, and combined with Ankoku's innate strategic brilliance, they can be used as powerful weapons.

In the case of when a sealing magic is pitted against him, Ankoku is able to use the usage of building up innate potential to override the sealing technique pitted against him. Sealing techniques require precise magical control, and the amount of magical power in each formula must be in an exact proportion to the user's magical power, otherwise the seal itself will collapse and be negated completely. However, the end result will be a large implosion of energy which can cause Ankoku himself to take damage if close enough to the seal.
