The Brave Saint system was created after the peace treaty between the Three Factions by copying the Devil's Evil Pieces system and the Fallen Angel's Artificial Sacred Gears technology. This was so that the Angels could increase their numbers since they could no longer depend on God to create new Angels. The Brave Saints, however, are currently only limited to the Seraphs.
The Brave Saints system, which the Heavens created by imitating the concept of the Evil Pieces, is the set of 13 cards which each of the Seraph and high-level Angels have in order to reincarnate other beings into Angels (high-level Angels choose the "suit" of their liking. Though the ones with a fixed "suit" are Michael with Spade ♠, Gabriel with Heart ♥, Raphael with Club ♣, Uriel with Diamond ♦). Most of the reincarnated Angels are former humans. Unlike Devils who base their choice on strength alone regardless of the species, the Heavens choose and reincarnate talented humans who are strong followers and have a "pure heart".
The Brave Saint allows the Angels to reincarnate or angelize humans into Angels. In contrast to the Evil Pieces which consist of different traits and values for each piece, the Brave Saints have many special effects which comes from actual card games like poker and blackjack.
The Brave Saint system, just like the traits of each of the chess pieces of the Evil Pieces have their own special ability and are based on card games, for example “Black Jack”. Reincarnated angels will gather together base on their numbers and suits to make a 21. For example each suit prepares reincarnated angels with the number 4, 6, and 10 and if they make them team up with the Ace (1) Irina and cooperate with her, they would be able to unleash overwhelming power.
Also, added in is the Poker’s system as well. Five High-level angels or Seraphs who are Kings gather members from Ace to Queen and by forming a ‘hand’ it will give birth to a certain power. An added advantage is that effect will still display with members of the different suits. The effect, however, will be stronger if it is between the members of the same suits. Similar with the Evil Pieces, the Brave Saints cannot reincarnate Gods/Buddhas and Dragon God into Angels even with a Joker card.

The Joker Card is a special type of card whose function is similar to that of the Mutation Pieces. A Joker does not belong to any of the 4 types of cards.
- The 12 cards used in the Brave Saints are based on the Twelve Apostles of Christian belief.
- Azazel has said that the creation of the Brave Saint system will result in a change in future Rating Games.
- Both of Uriel's named Brave Saints are named after Roman emperors.
- Each member of the Brave Saint became a member of Team Trump Card of Heaven for the Azazel Cup (with the exception of Irina Shidou and and Caesar Villiers).
- In Volume 23, it was mentioned that there is another Joker (also knows as the Extra Joker), but the status and information on this person is currently unknown.
- It was mentioned by Lint Sellzen that she is a Extra Joker candidate, when she revealed herself to be a newly Reincarnated Angel with silver wings and there are also several other people as Extra Joker candidates. Silver-winged Angels were candidates for the [Extra Joker] position that existed among reincarnated Angels. There were a number of people who could utilise the [Joker] in the Angels’ [Trump Card] prepared in order to act as a substitute. The [Extra Joker] in the Angels’ [Trump Card] system was used when a [Joker] couldn’t be utilized or when a substitute of the [Joker] was needed to be on the move. It was a feature based on the item used to reincarnate someone into a reincarnated Angel, [Trump]’s Extra Joker (Joker’s semi card).
