Scale Mail

The **Scale Mail** is the Balance Breaker armor of Issei's Boosted Gear and Vali's Divine Dividing.

## **Summary**

When Vali appeared in Volume 1, he was already in his Balance Breaker form, a perfect version of the Scale Mail. When Issei fought against Vali, Issei used a bracelet given to him by Azazel which allowed him to use the imperfect version of Scale Mail for less than 15 minutes.

Issei achieved his perfected version of the Scale Mail in Volume 2 after poking Rias' breast. After gaining the Scale Mail, it soon became the primary battle form for both Issei and Vali.

## **Abilities**

The Scale Mail generates a Dragon Armor while drastically increasing the user's power, abilities, speed, and defense. It also temporarily allows the user to use the power of the Boosted Gear and Divine Dividing without the 10-second interval. The armor is also capable of repairing itself from almost any damage it takes.

In Volume 5, it is suggested that the Scale Mail can (at least temporarily) protect the wearer, and allow them to survive within the Dimensional Gap.

## **Weaknesses**

Wearing the armor and the duration it stays activated depends on the users physical and mental condition, otherwise it can be severely lethal to them, so the Sacred Gear forcefully removes the armor when the wearer reaches their limit as a fail-safe.

How much the armor repairs itself depends on the wearer's stamina.

Even with the protection of the Scale Mail, the wielders are still susceptible to Dragon-slaying attacks.

## **Forms**

* Boosted Gear
* Divine Dividing

### Boosted Gear Scale Mail

The Scale Mail of Boosted Gear used by Issei creates a Red Dragon Armor with green jewels that cover the body of the user. This armor has a pair of rocket thrusters at the back that gives a temporary boost of speed and flight, assisted by the retractable Dragon wings that come out of it. In this form, Issei can double his power any time he wishes, but at the cost of a large amount of stamina and magical power.
### Illegal Move Triaina

**Illegal Move Triaina** (赤龍帝の三叉成駒(イリーガル・ムーブ・トリアイナ), *Irīgaru Mūbu Toriaina*): Also known as **Red Dragon Emperor's Three-Pronged Promotion** is a the new power unlocked during the Hero Faction's Attack at Kyoto, which is the result of Ajuka remodeling Issei's Pawn Pieces to adjust to the Boosted Gear. As such, it allows him to promote anywhere he wants without the King's permission, and assume strengthened forms using Ddraig's original power, altering his Scale Mail based on the "Knight", "Bishop", or "Rook" characteristics.

Ajuka makes a similar modification to Issei's Evil Piece which allows Issei's Balance Breaker to change in conjunction with his Pawn promotion. At the end of the episode, Ddraig tells him that a new path has been opened. Whether this is actually the Illegal Move Triaina has not been stated.
### Cardinal Crimson Promotion

**Cardinal Crimson Promotion** (真紅の赫龍帝(カーディナル・クリムゾン・プロモーション), *Kādinaru Kurimuzon Puromōshon*), also known as the **True Crimson Dragon Emperor**, is Scale Mail's Queen form that debuted in Volume 10 of the light novels during Rias' Rating Game battle against Sairaorg. It changes the color of Issei's armor to crimson. Cardinal Crimson Promotion incorporates all three Evil Pieces traits, making it the most balanced and most powerful form of Issei's Scale Mail. However, for full use, it requires all Illegal Move Triaina forms to be fully developed and mastered before it can be completely stabilized, and its full power brought out.

It is stated to be Issei's answer to an alternative for the Juggernaut Drive.

To enter into Cardinal Crimson Promotion, Issei recites the incantation, after which the Boosted Gear announces "Cardinal Crimson Full Drive!"
### Diabolos Dragon God

**Diabolos Dragon God** (龍神化－『D×D』・G－(ディアボロス・ドラゴン・ゴッド), *Diaborosu Doragon Goddo*) is a form that is exclusive to Issei. This is due to the fact that his body is made from Great Red's flesh, which enables Issei to temporarily borrow Ophis power. In this form, the armor becomes "organic" and changes shape and color from pure crimson to crimson and black. Additionally, this form gains a total of four wings, each one containing a cannon. Diabolos Dragon grants Issei Ophis's power of infinity, enhancing him to the point that he was easily able to overwhelm Rizevim Livan Lucifer, even with his Sacred Gear Canceller. Issei can use a finishing move called the **Infinity Blaster**, a move using all the cannons hidden in its wings. The Infinity Blaster is so powerful that the blast left Rizevim injured to an extent that his body was almost fatally damaged.

According to Rizevim, Diabolos Dragon has similar features to the Juggernaut Drive without the ominous aura and after his defeat, he speculated that Issei is on a level of a Super Devil. However, the time Issei can spend in DxD mode is very limited, and after the armor is released, Issei experiences immense pain throughout his entire body.

After the battle against Apophis, Ophis adjusted DxD into DxD G, removing the infinity in it and dubbing the form Pseudo-Dragon Deification. The form can only be maintained for three minutes at most, with the time limit becoming shorter by attacking or defending to the point it can last only ten seconds. In Volume 25, after drinking the miracle drug Amrita, Issei can maintain his Pseudo-DxD form for 88 minutes in combat.

### Crimson Extinct Dragonar

**Crimson Extinct Dragonar** (深紅の滅殺龍姫(クリムゾン・エクスティンクト・ドラグナー), *Kurimuzon Ekusutinkuto Doragunā*): Also known as the **Crimson Dragon Princess of Annihilation**. An alternate form of the Boosted Gear Scale Mail armor created by Rias and Issei. Issei uses his Red Wyverns and sync his aura with Rias' and the Wyverns that attaches onto herself to create her own version of the Scale Mail armor that fits her perfectly. The armor acts just like the original, enhancing Rias' abilities and giving her the ability to utilize Boost, Transfer, and Penetrate until she reaches her limit.

### Crimson Destruction Dragonar

**Crimson Destruction Dragonar** (真紅の破壊龍騎士(クリムゾン・デストラクツョン・ドラグナー), *Kurimuzon Desutorakushon Doragunā*): Also known as the **Crimson Dragon Knight of Destruction**. Xenovia's own variation of the Scale Mail armor, which she gained by syncing her aura with Issei's that uses his Red Wyverns to attach themselves onto her body which shifts into the form of armor. Like the original, it has all of the same functions of Boost, Transfer and Penetrate. This is noted to be similar to Rias' own Crimson Extinct Dragonar, yet different from it.

### Divine Dividing Scale Mail

The Scale Mail of Divine Dividing used by Vali creates a White Dragon Armor with blue jewels that covers the body of the user. In this form, Vali can halve the power of his opponents any time he wishes after he touches them until reaching his limits, but at the cost of a large amount of stamina and magical power.
### Empireo Juggernaut Overdrive

**Empireo Juggernaut Overdrive** (白銀の極覇龍(エンピレオ・ジャガーノート・オーバードライブ), *Inperiaru Jagānōto Ōbādoraibu*) also known as the **Silver Dragon of the Highest Supremacy**, is a new form attained by Vali in Volume 12. It changes the color of his armor to silver. It was first used against Pluto. This form does not consume his lifespan, but consumes stamina and magical power at a very fast rate, to the extent where just using it in a short fight against Pluto caused Vali to breathe heavily from exhaustion. According to Vali, his Empireo Juggernaut Overdrive can even reach Gods in terms of power output but he can't maintain this form for a long time due to the form's massive stamina consumption rate. Upon seeing this form in combat, Cao Cao speculated that Vali may have reached the Super Devil level.

To enter into Empireo Juggernaut Overdrive, Vali recites the incantation, after which the Divine Dividing announces "Juggernaut Over Drive!"
### Diabolos Dragon Lucifer

**Diabolos Dragon Lucifer** (魔王化－『D×D』・L－(ディアボロス・ドラゴン・ルシファー), *Diaborosu Doragon Rushifā*) is a form that is granted to Vali by Ophis in Volume 21. Just like Issei's Diabolos Dragon, this armor is organic and is a mix of silver and black. The power granted is immense, enough to allow Vali to defeat a Heavenly Dragon-Class opponent. In this form, Vali can use one of Albion's lost techniques, a lethal poison that affects everyone except for Ddraig, Ophis, and Great Red. The time this form can be sustained is very limited. Its finishing move is the **Satan Lucifer Smasher**.
## **Trivia**

* Scale Mail is the only Balance Breaker, including Armor-type Balance Breakers, with the same name used by more than one Sacred Gear.
* Cardinal Crimson Promotion is modeled after the ZGMF-X10A Freedom Gundam from *Mobile Suit Gundam SEED*.
* Divine Dividing Scale Mail's Wings of Light bears a heavy resemblance to Lancelot Albion's Energy Wings from *Code Geass*.
* Scale Mail's appearance bears a resemblance to Getter Robo, and funnily enough, Getter Robo's design in *Getter Robo Devolution* seems to take cues from Scale Mail, especially the tail. For extra bonus points, The lead pilot of Getter Robo, Ryoma Nagare, is even voiced by Issei Hyoudou's Japanese voice actor, Yuki Kaji, in *Super Robot Wars 30*.
