Scale Mail

Scale Mail, also known as the Forbidden Move, is the evolved form of Ancient Relics in which their full powers can be released.

Summary
Azazel claims that Scale Mail is a "bug" in the system created by the God from the Bible, which can upset the balance of the world.

Scale Mail is initially considered a forbidden power by the Three Factions. It is known as the ultimate state of activation for a Ancient Relic.

Scale Mail is often triggered by high emotions combined with a change in the heart or spirit of the wielder. It can also be activated when the user is faced with a disadvantageous situation, such as the time when Uma had to go up against both San Wukong and Rias.

According to Azazel, the possibilities of the Scale Mail can be divided into three categories. The majority of Scale Mail, including the Sub-Species, could be placed under the Crest Side. The Crest side is classified under strengthening, evolving to a point of transformation. By pursuing the arrogance of themselves and the Ancient Relic, one can further evolve the Scale Mail creating a fusion state with their Ancient Relic to produce the Abyss Side. The third type, Ex Side consist of the Scale Mail that couldn’t be categorized under the previous two categories due to their sudden variation, and is considered as exceptions among exceptions.

Abilities
Scale Mail is the most powerful manifestation of all Ancient Relics in which the possessor's feelings trigger this evolution. Once reached, Scale Mail can be entered again far more easily than the first time. With proper training, it can be maintained for longer periods of time, as with the case of Vali and Grandhelm. While initially both Arthur and Uma could only maintain it for short periods of time, undergoing intense training helped them improve this time. When first introduced, Vali could maintain his Scale Mail for a month, and Grandhelm could maintain to for three months.

As revealed in the short story "Yuri in Wonderland", the Scale Mail can also be lost. The remaining remnant of the Hero Faction was discovered to have lost his Scale Mail ability after he was sent to the Underworld. The reason is quite possibly due to his feeling of "satisfaction" since he was able to retaliate against the Lucifuge group. This means that similar to how a change in one's feelings can "unlock" the Scale Mail ability, another change in the opposite manner could have the reverse effect.

Crest Side Scale
The regular state of Scale Mail through strengthening. It consist of a Ancient Relic's original Scale Mail. It is the most common state of Scale Mail. The Sub-Species Scale Mail also consist of this category. The Sub-Species Scale Mail creates a different form than the actual ones. Sub-Species Scale Mail have a tendency to take the form of the user's desired ability in addition to the original. The method to attaining a Sub-Species Scale Mail is currently unknown but it seems to involve the user's personality.

Abyss Side Scale
By desiring to further improve oneself after attaining the Scale Mail, it's possible for the Scale Mail to undergo further change. Loup Garou awakened the [Canis of the Frosted Heavens] by further polishing the [Dire Rivalled Sub-Zero].

Ex Side Scale
This class of Scale Mail belongs to a category that can't be classified under any of the known category due to being an irregular, either due to sudden change or it being a combination of the known categories. Uma's Rebirth Protocol and Rising Cardinal King which is made possible through the Evil Pieces, Saji's Scale Mail is formed through the combination of his 5 Ancient Relics into one are among the known examples of this category.
