The Silver Devil is the phenomena behind the principle of Sincere. The Silver Devil is in line with the concept of "Beyond I AM" in which its nature is not only different but also conceptually superior to the concept of Christopher Sincere Pride as a formless, transcendental boundless realm, that is, even a boundless beyond dimensional reality beyond trans-fictional ever-increasing hierarchy would be nonexistent in comparison to The Silver Devil, regardless if the setting of a verse is infinite-dimensional or not. This is the 1st layer of the phenomena behind the principle of Sincere.

The Silver Devil makes his first appearance in Solecism III. He appears before Giovanni Opus Demiurge, but only briefly. However, because Sincere could not control the release of the form, his body collapsed, irreversibly disappearing from all modes of existence and all modes of nonexistence; completely leaving the Allscape.

In Pharos of the End, The Silver Devil returns. In this series, Christopher Sincere Pride is fully capable of maintaining this form.

In Solecism - Rajashekhara (Heir to the Stars III), The Silver Devil appeared before Obsidianiste, making its official first appearance in chronological feats. This was the advent of The Silver Devil, as The Silver Devil, appeared in this moment, the realm of Cataphysics started to break for fear of him deciding to “Act” or “Will” even once.

The Silver Devil possesses all of Christopher Sincere Pride's abilities, for they are literally one and the same. The Silver Devil is the true form of Christopher Sincere Pride that exists outside Existence and Nonexistence, wielding power that equates to The Ace of Spades.
