**Boosted Gear**, also known as the **Red Dragon Emperor's Gauntlet** (赤龍帝の籠手, *Sekiryūtei no Kote*), is a Sacred Gear wielded by Hyoudou Issei. Listed as one of the original thirteen Longinus, specifically a mid-tier Longinus, it has the spirit of the Welsh Dragon, Ddraig, residing within it.

## Summary

In the past, Ddraig fought against his arch-rival, the Vanishing Dragon, Albion, in a battle that was interrupted by the Angels, Devils, and Fallen Angels who were at war during the time. In anger, both Dragons attacked the leaders of the Three Factions, which led to their bodies being destroyed and their souls being sealed into two separate Sacred Gears, with Ddraig moving into the "Boosted Gear", a Sacred Gear that eventually became one of the eighteen varieties of Longinus.

It is revealed that when a host of the Boosted Gear dies, a fragment of their consciousness is stored inside the Boosted Gear, while normally only waking up during the activation of the Juggernaut Drive. However, there are two people who maintain a degree of consciousness; Belzard and Elsha. Belzard is known as the strongest Boosted Gear possessor due to being known for defeating two White Dragon Emperors in his lifetime, while Elsha is known as the second-strongest and the strongest female.

It is revealed that a past possessor of Divine Dividing was stored within the Boosted Gear when Issei used one of Albion's jewels to create the Dividing Gear. The past possessor of the Divine Dividing then used his halving power to diminish the dark thoughts of the Boosted Gear's past possessors, allowing Issei to awaken a power opposite to Juggernaut Drive: **Cardinal Crimson Promotion**, with a different chant.

All the past possessors sacrificed themselves in order to save Issei's soul from Samael's curse. Issei temporarily gained the ability to use **Super Gigantic Balance Breaker** after merging with Great Red, and lost the ability to use it after the merger was undone.

Euclid Lucifuge reveals that he created a replica version of the Boosted Gear by collecting information of the Red Dragon Emperor's soul and the Sacred Gear from Issei's original body that was left in the Dimensional Gap by using the Holy Grail. Unlike the original Boosted Gear, however, the Boosted Gear Replica appears on the user's right hand with silver lining and uses the souls of famous Dragons to activate it. The replica was destroyed after Euclid's defeat against Issei.

Issei and Ddraig unlocked one of Ddraig's original powers called ***Penetrate*** which allows Issei to bypass defensive powers, such as Rizevim Livan Lucifer's Sacred Gear Canceler.

Issei uses a new chant that he and Ophis created, alternating lines, that allows him to temporarily borrow Ophis' power of infinity. Ddraig names the new form **Diabolos Dragon** or DxD.

As a result of taking the miracle drug Indra offered Issei, he is now able to summon Ddraig from the Sacred Gear for a certain amount of time.

Issei managed to unlock a new form: **Apocalypse AnswerArms** by combining with his Familiar, Ryuuteimaru.

Issei was able to unlock the dormant Great Red power in his body and achieved **Diabolos Dragon**.

## Appearance

Boosted Gear takes the appearance of a red gauntlet with a green jewel and 2 golden spikes that manifests on the user's arm. In the anime, its initial state looks like a regular Twice Critical. After a certain time, it transforms into a more Dragon-like gauntlet that covers up the user's hand and a majority of the arm. When the Boosted Gear reaches its second liberation, it gains another green jewel and a total of 10 golden spikes, aside from covering more of the user's arm.

## Abilities

 File:Gif 200x112 cea968.gif
Boosted Gear is a red gauntlet housing Ddraig, the Red Dragon Emperor, which allows the user to double their powers every ten seconds without limit until the user reaches their limit, whether it's their physical abilities, magic or demonic power based on the user. It has been described as allowing the wielder to surpass the powers of God and Seven Great Satans for a temporary amount of time.

In response to their user's feelings, the Boosted Gear can transform into its final state, letting the user to transfer their increased power to other people or items, increasing their capabilities. The transferred power can even be performed on multiple targets at the same time, however, about 70 to 80 percent of the boosted power will be transferred. Boosted Gear can also determine the opponent's power level and inform whenever his boosted power reaches a sufficient enough level to defeat an opponent. Issei can transfer power into certain body parts such as eyes for enhanced vision.

Boosted Gear has proven to be able to store either weapons and items inside the user based off the user's desire, letting them wield their capabilities such as Ascalon (after some modifications). He was able to do the same thing after integrating one of the jewels from Divine Dividing's Scale Mail.

After venturing into the Boosted Gear, Ddraig unlocked one of his original powers, *Penetrate*, letting the user bypass all defenses, bypassing even Rizevim's Sacred Gear Canceler. Penetrate is also capable of penetrating through attacks and causing damage to the core of opponents, potentially resulting in fatal injury. Issei was capable of using *Transfer* to focus *Penetrate* to his eyes, letting him see through solid objects (i.e clothing) at will.

Issei unlocked Ddraig's ultimate finishing move named the **Blazing Inferno of Scorching Flames**, which allows him to burn even Gods to ashes to the point of burning their souls too.

## Weaknesses

With Ddraig sealed within Boosted Gear, its possessors becomes vulnerable to the same weaknesses common to Dragons, such as Dragon Slaying magic, swords, and curses, as if they were Dragons themselves.

Also continuous use of Boosted Gear's doubling abilities will continue to drain the user's stamina, burdening their body far more than other Sacred Gears. If the user reaches their limit, the Boosted Gear would enter its **Burst** state, signifying their limit, where the user will or have exceeded their physical limit.

## Forms

* Gauntlet
* Dividing Gear
* Balance Breaker
* Evil Pieces
* Dragon Gods
* Others

### Base Form: Twice Critical (Anime only)

 File:Twice critical.jpg
The initial form of the Boosted Gear in the anime. It takes a form of a red, armored bracer with yellow accents and a green jewel on top of the palm area. The fingers aren't covered. It was initially mistaken as a Twice Critical.

### Initial Form: Boosted Gear

 File:First activation of Boosted Gear.png
The form where it was finally realized that it is the Boosted Gear. It first debuted during Issei's last battle with Raynare. It is a red, claw-shaped gauntlet with yellow accents and green inscriptions. It is also known as the **Dragon Booster** (ドラゴン・ブースター, *Doragon Būsutā*).

### Upgraded Form: Boosted Gear Gift

 File:Boosted Gear Back view.jpg
**Boosted Gear Gift** (赤龍帝からの贈り物, ブーステッド・ギア・ギフト, *Būsuteddo Gia Gifuto*), also known as the **Gift from the Red Dragon Emperor** (赤龍帝からの贈り物, *Sekiryūtei kara no Okurimono*), is Boosted Gear's third and final form in the shape of a gauntlet. It has the same appearance as the original Boosted Gear, except with a second jewel that grants the user the Transfer ability and that it covers more of the user's arm. It debuted during Rias' Rating Game against Riser Phenex.

### Dividing Gear

 File:D65c-lliCAI.jpg
**Dividing Gear** (白龍皇の籠手, ディバイディング・ギア, *Dibaidingu Gia,*), also known as the **White Dragon Emperor's Gauntlet** (白龍皇の籠手, *Hakuryūkō no Kote*), is the Boosted Gear version of Divine Dividing. It debuted in Volume 4 during Issei's first battle against Vali, where the former placed one of Albion's jewels on his right gauntlet. The Dividing Gear resembles the Boosted Gear but is white in color, has a blue jewel instead of green, and rests on Issei's right hand, as opposed to his left. With Dividing Gear, Issei gains all the powers of Divine Dividing. However, due to it consuming his lifespan, it was banned from use by Azazel.

### Dividing Wyvern Fairy

**Dividing Wyvern Fairy** (白龍皇の妖精達, ディバイディング・ワイバーン・フェアリー, *Dibaidingu Waibān Fearī*), also known as **Fairies of the White Dragon Emperor** (白龍皇の妖精達, Hakuryūkō no Yōseitachi), creates small dragons from the gems of his armor. It first appeared in Volume 16, replacing Dividing Gear. Originally, the Wyverns were only able to use White Dragon Emperor's powers of Divide and Reflect and unlike the Dividing Gear, this does not reduce Issei's lifespan.

Issei managed to change it so that these Wyverns could use either the Divine Dividing's or **Boosted Gear**'s abilities. As such, the White Wyverns can use **Divide** and **Reflect**, while the Red Wyverns can use **Boost**, **Transfer**, and **Penetrate**. He usually uses the White Wyverns to reflect his Dragon Shots around so he can attack his opponents from different directions, but he can also use the Red Wyverns to double his powers to the limit, allowing him to use the Longinus Smasher.

After training with Rias, Issei manages to make use of the red Wyverns to attach themselves on Rias to create her own variation of the Boosted Gear Scale Mail armor called **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*). Issei also made use of the red Wyverns to attach themselves on Xenovia to create her own variation of the Scale Mail armor called **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*).

### Boosted Gear: Scale Mail

 File:Issei going into Balance Breaker Boosted Gear Scale Mail.gif
**Boosted Gear: Scale Mail** (赤龍帝の鎧, ブーステッド・ギア・スケイルメイル, *Būsuteddo Gia Sukeiru Meiru*): Also known as the **Armor of the Red Dragon Emperor** (赤龍帝の鎧, *Sekiryūtei no Yoroi*), is the Balance Breaker of Boosted Gear which creates a Red Dragon Armor with green jewels that cover the user's body and strengthens its powers and abilities. When active, the user can double their power without the 10-second time limit, this also applies to later forms. The armor has two rocket thrusters on it's back for a temporary boost of speed and flight, from them can come out a pair of retractable Dragon wings that enables the user for proper flight. Originally, it did not have wings, however, after Issei goes into Juggernaut Drive in Volume 6, it gains Dragon wings. In the third season of the anime, Issei's perfect Balance Breaker already has wings. The Scale Mail also allows the user to survive in the Dimensional Gap.

### Juggernaut Drive

 File:Boosted Gear Juggernaut Drive Incomplete Transformation.gif
**Juggernaut Drive** (覇龍, ジャガーノート・ドライヴ, *Jagānōto Doraivu*): Also known as the **Dragon of Supremacy** (覇龍, *Haryū*), like Divine Dividing, Boosted Gear also has access to this form. This form unleashes the full power of the Welsh Dragon, but the user will lose their sanity and their life will also be devoured. Issei first went into Juggernaut Drive, which would also be his last time. It also has access to the **Longinus Smasher**, one of the most powerful attacks of the Boosted Gear.

### Illegal Move Triaina

 File:DxD Hero OP - Illegal Move Triana.gif
**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 the **Red Dragon Emperor's Three-Pronged Promotion** (赤龍帝の三叉成駒, Sekiryūtei no Mitsumata Narikoma), is the enhanced form of Issei's Scale Mail, where the armor changes to various forms based on the Evil Pieces' traits.

The available forms for the Illegal Move Triaina are:

* Welsh Sonic Boost Knight (龍星の騎士, ウェルシュ・ソニックブースト・ナイト, *Werushu Sonikku Būsuto Naito*)
* Welsh Dragonic Rook (龍剛の戦車, ウェルシュ・ドラゴニック・ルーク, *Werushu Doragonikku Rūku*)
* Welsh Blaster Bishop (龍牙の僧侶, ウェルシュ・ブラスター・ビショップ, *Werushu Burasutā Bishoppu*)

### Cardinal Crimson Promotion

 File:Cardinal Crimson Promotion In DxD HER.jpeg
**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** (真紅の赫龍帝, *Shinku no Kakuryūtei*), is the Scale Mail's evolution of the Queen form. It changes the color of Issei's Scale Mail armor from red 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. It is Issei's answer to a power different from the Juggernaut Drive.

### Diabolos Dragon

 File:DxD V22 illustration 4.png
**Diabolos Dragon** (Ｄ×Ｄ, ディアボロス・ドラゴン, *Diaborosu Doragon*): Is a new form Issei gained in Volume 20 from tapping into Ophis' power inside him. 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" changing the armor's shape, and the armor's color changes from pure crimson to a mix of crimson and black. Additionally, this form gains a total of four wings, each one containing a cannon. Two of the cannons are over his shoulders and the other two are under his arms. In this mode, the Boosted Gear's announcement voice becomes an amalgamation of Ddraig and Ophis' voices and instead of "Boost", the Boosted Gear announces "D∞D" as Issei directs Ophis' infinity power. Diabolos Dragon grants Issei Ophis' power of infinity, enhancing him to the point at which he was able to easily overwhelm Rizevim Livan Lucifer, overpowering his *Sacred Gear Canceller*.

Diabolos Dragon's finishing move is the **Infinity Blaster**, a powerful aura blast in which Issei directs Ophis' power to the four cannons stored in the armors wings, then fires them. Infinity Blaster is so powerful that the blast left Rizevim injured to a extent that his body is almost fatally damaged. According to Rizevim, Diabolos Dragon has similar features to the Juggernaut Drive without the ominous aura. However, the time Issei can spend in Dragon Deification is very limited, and after the armor is released, Issei experiences immense pain throughout his entire body and becomes comatose.

Following Issei's battle against Apophis, Ophis adjusts the D×D to prevent the severe backlash of that form and is subsequently renamed the D×D・G (龍神化－『Ｄ×Ｄ』・G－, ディアボロス・ドラゴン・ゴッド, *Diaborosu Doragon Goddo*) in tandem with Vali's D×D・L. A modified version of chant was used by Issei. After drinking the miracle drug Amrita, Issei can maintain his Pseudo-DxD form for 88 minutes in combat. During his fight with Angra Mainyu, Issei unlocks *True-Dragon Deification* (真の龍神化, *Shin no Ryūjin-ka*) , which is described as having Devil, Dragon, and God aura. Hades notes that Issei's power in this form is even greater than when he was in Pseudo-DxD.

Issei and Ophis alternate lines when chanting the Diabolos Dragon chant.

* English
* Kana
* Romanji

Issei: **"The Crimson Red Dragon dwelling within me, awaken from your dominance"**
Ophis: **"The Crimson Heavenly Dragon I possess within me, rise up to become a King and roar"**
Ophis: **"The jet-black God of Infinity"**
Issei: **"The glorious Red God of Dreams"**
Both: **"Watch over the forbidden existence we shall become that transcends the boundaries"**
Both: **"Thou shall dance like radiance within our inferno!"**

Issei: 我に宿りし紅蓮の赤龍よ、覇から醒めよ
Ophis: 我が宿りし真紅の天龍よ、王と成り啼け
Ophis: 濡羽色の無限の神よ
Issei: 赫赫たる夢幻の神よ
Both: 際涯を超越する我らが禁を見届けよ
Both: 汝、燦爛のごとく我らが燚にて紊れ舞え

Issei: Ga ni yadorishi guren no akaryū yo, ha kara sameyo
Ophis: Waga yadorishi shinku no Tenryū yo,-ō to nari nake
Ophis: Nurebairo no mugen no kamiyo
Issei: Kakkakutaru mugen no kamiyo
Both: Saigai o chōetsu suru warera ga kin o mitodokeyo

### Apocalypse AnswerArms

 File:Issei’s AxA form.jpeg
**Apocalypse AnswerArms** (A×A, アポカリュプス・アンサーアームズ, *Apokaryupusu Ansāāmuzu*): Issei's AxA form. This form is the result of Issei combining with his familiar Ryuuteimaru, who is the manifestation of Great Red's power. The power of this form is so great that it overwhelms Tartarus, a Primordial God in Greek mythology. It has the power to destroy the entire planet with its destructive power. Because of the weapons that was installed in Ryuuteimaru, Issei has gained new abilities in this form. The drawbacks of this form is that it has an extremely high consumption rate which gives it a short time limit. Furthermore, Ryuuteimaru is unable to move for a few days and Issei himself suffers fatigue for a few days. It is determined that these burdens compared to DxD G are much lighter.

### Super Gigantic Balance Breaker

**Super Gigantic Balance Breaker** (超巨大禁手, ちょうきょだいバランス・ブレイカー, *Chōkyodai Baransu Bureikā*) is the form that Issei takes after combining with Great Red. It resembles Boosted Gear's normal Scale Mail, except that it is incredibly enormous in size and now has access to the **Longinus Smasher** that was previously exclusive to the Juggernaut Drive.

### Crimson Extinction Dragonar

**Crimson Extinction 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** (深紅の滅殺龍姫, *Shinku no Messatsu Tatsuki*). A form developed for Rias Gremory, which is a combination technique between Issei and her. Issei uses his Red Wyverns and sync both of their auras while the Wyverns attach themselves to Rias to create her own female variation of the Scale Mail. The armor acts just like the original, strengthens 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 **Crimson Dragon Knight of Destruction** (真紅の破壊龍騎士, *Shinku no Hakairyū Kishi*). Xenovia Quarta's own variation of the Scale Mail armor, which she gained by also synchronizing her aura with Issei's to use 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' and yet different.
## Trivia

* Boosted Gear and Divine Dividing were designated as Mid-Tier Longinus due to portions of the Heavenly Dragons' powers and abilities being sealed by God of the Bible, however, since these restrictions were being removed, their rankings might change and could become High-Tier Longinus.
* Super Gigantic Balance Breaker is a special form made for Volume 12 only.
* Cardinal Crimson Promotion is modeled after the ZGMF-X10A Freedom Gundam from *Mobile Suit Gundam SEED*. The Diabolos Dragon's Infinity Blaster is very similar to the Freedom's Full Burst attack.
* Longinus Smasher and Super Gigantic Balance Breaker appear to be homages to the Mega Smasher and Gigantic Exceed of Guyver.
* Among all Sacred Gears, the Boosted Gear has the most named possessors (Issei, Elsha and Belzard).
* Boosted Gear is the only known Longinus to have a replica of it made.
* In the anime, the Third Form: Boosted Gear Gift had an additional four golden spikes in the upper part of the gauntlet and two on the side of the wrist whereas in the manga, which follows the light novels, the six golden spikes aren't shown.
	+ In the anime, using **Boosted Gear Gift** appears to cause a pleasurable sensation in females to who the "Gift" is given to.
* In Episode 11 and 12 of the anime's second season, Issei demonstrated the ability of extending the blade far longer than its normal length, whether this is a normal ability of the sword or an ability gained with the fusion with the Boosted Gear is not clear.
