Issei Hyoudou

**Issei Hyoudou** is the main male protagonist of *High School DxD*. He is a third-year high school student at Kuoh Academy in Class 3-B and a member of the school's "Perverted Trio", a trio of the most perverted men in the entire student body.

He is the Pawn of Rias Gremory's Peerage and a member of the Occult Research Club. After the Evil Dragon War, he was promoted to the rank of a High-Class Devil, becoming the King of his own independent peerage, and is one step closer to fufilling his dream owning a harem and becoming a "Harem King".

Due to his possession of the Longinus; the Boosted Gear, which hosts the **Welsh Dragon**, Ddraig, Issei is the direct rival of Vali Lucifer, who is the host of the Vanishing Dragon; Albion, who is Ddraig's archrival.

## **Appearance**

Issei is a high school student of average height with short spiky brown hair, with two short locks of hair behind his head, and light brown eyes. Following his training with Tannin, he gained a more muscular and toned build.

While he has worn various outfits throughout the series, his most commonly worn outfit is the Kuoh Academy boys' school uniform, which consists of a blazer (more commonly black, although in other media is shown with a tinge of purple or grey, with white accents) over a white, long-sleeved dress shirt with black highlights with a black ribbon on the collar, matching black pants, and brown dress shoes. However, Issei's uniform differs in the fact that he wears a red T-shirt underneath his open dress shirt and blazer, and wears blue and white sneakers in place of dress shoes.

Before fighting Riser in a rematch, Issei's left arm was transformed into a Dragon's arm, which needed a ritual performed regularly by Rias and Akeno to appear human.

He has been said to show manly expressions by his paternal grandmother. Issei's height is 170 cm (5 feet 7 inches) and body weight is 62→65 kg (137→140 lbs.).

## **Personality**

Issei is shown to be notably unintelligent with an ongoing perverted nature, often to make lecherous fantasies, and utterly obsessed with women's breasts and having his own harem. This has caused him to be instantly labeled as a pervert among the girls of Kuoh Academy and has gained him notoriety for being one of the members of Kuoh Academy's Perverted Trio.

Despite his pervertedness, Issei is courageous, selfless and unwaveringly determined to protect those who are important to him, despite almost dying by the hands of his opponents. Having great kindness, Issei is also very caring, "putting his nose into other people's business" as he helped Yuuto Kiba and Akeno Himejima overcome their fears and hatred of their mournful past. Due to this, he gained strong friendship from his comrades and affection from most girls of the Occult Research Club and a strong sense of friendship with higher-up Devils like Rias' family; they have told him to use the same titles for them as Rias (Father, Mother, Brother, etc.), yet he still remains the same.

He has a habit as mentioned by his mother of not forgiving himself if he does something wrong: always saying sorry if said thing is mentioned, and showing an expression of pain and regret. He is also fiercely loyal to his comrades and is always willing to stand up for them. Issei's kindness also have a positive influence on others including former enemies. When Issei suggested to Cao Cao to use his True Longinus to help and protect people, Cao Cao acknowledged had he and Siegfried met and befriend Issei earlier, they would not have ended up becoming terrorists in the Khaos Brigade. Another sign of his kind nature is that despite wanting to lose his virginity, Issei refuses to take advantage of women when they are upset, even if they themselves are willing to. This happened when Akeno appeared in front of him naked and wanted to have sex to forget about her sad past and her father. However, Issei refused, knowing it will just hurt her more, and put her clothes back on and hugged her to comfort her.

After his murder by Raynare, Issei had developed a fear of admitting his feelings to the girls, as he thought it would cause them to turn their backs on him. This would also cause him to become oblivious to the feelings of the girls around him (save for Rias after his confession), often believing they are simply teasing him. He acknowledged that this would never happen, but it was still an intense fear. It is also why he was so insistent on trying to lose his virginity, as he believed that no woman would ever want to be in a true relationship with him and that him having sex was the best he could hope to achieve as a sense of relief.

Despite that, even when the girls of the Occult Research Club such as Akeno or Xenovia propositioned him into making love to them, Issei would always initially hold himself back, as he would sometimes look at them with a frightened gaze, a fact which Akeno, Asia and Koneko later noticed.

His fears were finally brought to attention when Akeno, Asia, and Koneko confronted him alone and helped him by getting him to admit his feelings and assuring him that they would always love him and so would Rias.

This inspired him to finally confesses his love for her which she reciprocated, effectively helping Issei move past his fears. Even with the knowledge that the girls do have romantic affection for him, he still has problems acknowledging some of their ongoing rivalries, an example being who gets to sit on his lap.

In reality, Issei has an innocent side; he is a boy who yearns for love and a true relationship, a side which he only shows to women who can see past his perverted exterior and love him for who he is and who he, in turn, has affections for. He shows this side to the girls of the Occult Research Club, for instance on his date with Akeno or when Rias takes him out on dates.

Initially, after reincarnating as a devil, he set about his desire for a harem as his initial goal, by having his peerage become his harem. After the Rating Game against Sona and Saji, he slightly changed the goal to having a harem peerage that wouldn't lose to anyone. Among his other goals include competing in Rating Games and making Rias the Champion of the Rating Games by becoming the *"Ultimate Pawn"* alongside Kiba, who promised to become the *"Ultimate Knight"* with him and his desire to become the Champion of the Rating Games himself after he obtains his own peerage. He is also deeply invested in his rivalry with Vali Lucifer, his Heavenly Dragon counterpart, as Issei promised to get stronger and defeat him, with the both of them reaffirming their promise to fight each other some day multiple times during the series and Vali suggesting that Issei create his own team like Vali which is different from his peerage. Their rivalry would heat up after the both of them enter the Azazel Cup, with Issei creating his own team, "Team Red Dragon Emperor of the Blazing Truth", to try to win the Cup and defeat Vali during the tournament. After the two of them passed the preliminary rounds, the two expressed their desire to continue their initial fight as the both of them promised not to lose until they meet each other in the Cup.

Due to experiencing intense fights in which he nearly died, Issei affirms his desire to create a world without war and protect his companions even if his enemy is a God.

While initially shown to be unable to understand the appeal of fighting, Shiva reveals that Issei has developed fondness of fighting strong opponents with strong beliefs, with Issei himself confirming that he has come to like defeating strong opponents as equally as groping female breasts. While Issei is shown to like battling strong opponents, at first he was unable to truly "enjoy" a fight (except his match with Sairaorg) due them mostly being life-threatening fights. This began to change after his match with Dulio, as he realized that competing in the Azazel Cup is mostly sport rather than a serious fight.

Issei is shown to admire strong individuals who have strong beliefs and convictions, seeing them as targets for him to catch up to. He is shown to admire Sairaorg Bael, after witnessing his strength and noble splendor and that respect intensified after learning that Sairaorg was talentless like him, as he noted their similar fighting styles. Due to his interest in Rating Games, he has developed a admiration towards Diehauser Belial and Rudiger Rosenkreutz, due to them being the Top 10 Rating Game players, with Issei especially admiring Rudiger Rosenkreutz; as he was a reincarnated devil like Issei himself. As Dragon, he is shown to admire Tannin, admiring his strength and his desire to help other Dragon as Issei considers him the true Dragon King due to his splendor, and Crom Cruach, due to his overwhelming power and his pride as dragon. While he was initially exasperated and annoyed by Fafnir and his panties fetish, Issei is shown to have developed a respect for him after he witnessed Fafnir's willpower and determination to protect Asia from Rizevim.

Issei is noted be be a very friendly person, able to become friends with anyone. Azazel stated that he has the ability to win over the trust of others easily and doesn't discriminate against anyone as others can feel at ease with him due to him not resenting anyone, with Azazel calling that ability a talent of Issei's. Issei's ability to attract companions, allies and enemies is further enhanced by him being the Red Dragon Emperor. According to Cao Cao, despite Issei's lack of natural talent and demonic power, Issei's ability to attract others by holding dragon powers is top notch compared to previous Red Dragon Emperors, as Cao Cao believes that Issei will become the most dangerous Red Dragon Emperor. According to Azazel, Issei makes a lot of irregular phenomena occur, for instance; a lot of Sacred Gear possessors near Issei were able to awaken irregular Balance Breakers (such as Yuuto, Gasper and Saji). Ophis stated that Issei is as strong as the number of companions he has. According to Azazel, Issei has the natural ability to make supernatural girls fall in love with him, while Millarca Vordenburg stated that most of the men who meet Issei become fascinated with him.

While initially being confused by his popularity among the devil children due to Oppai Dragon, Issei eventually embraced the role of being the Oppai Dragon and began acting as a hero for the children as was demonstrated in Volume 4, where he carried the wishes of child fans during his match with Sairaorg Bael, promising to defeat him for the sake of Rias and the children who believed in him. Issei has placed the his desire to protect the children of the Underworld and of the other factions as one of his goals as seen when he defeated various foes who threatened the children and their dreams such as Shalba Beelzebub, Grendel, and Erebus. In fact, due to Shalba's insanity and him promising to kill the children of the Underworld for rejecting him as a Satan, Issei killed him to stop his malice from reaching the children.

In battle, Issei is sometimes very stubborn, and due to his emotions, he often charges ahead towards his enemies without a second thought whenever his comrades are insulted, treated badly, or easily defeated. Azazel has stated that it is one of Issei's bad habits. Lately, he has started to become more tactical in his battles, using technique-type strategies to defeat opponents, as shown when he used the abilities of the Wyverns in a unique way to defeat Euclid.

Issei also displays strong moral principles, as seen when he initially refused to actually kill his enemies. Issei still rarely ever kills his enemies and prefers to either let others do so or simply let them face arrest. While Issei can carry grudges, he is not above forgiving his enemies and becoming friends with them due to his kindness, as seen with Riser, Kuroka, Vali and Cao Cao.

## **History**

Before Issei's birth, his mother became pregnant twice, but the pregnancies ended in miscarriages. So when Issei's mother got pregnant for the third time, his father had paced back and forth in front of a Shinto shrine honestly wishing that this time they would succeed. When the newborn was finally born he was named Issei, meaning "honesty", for his father's honest prayers.

He is a childhood friend of Irina Shidou and they would always play together back when she still lived in the neighborhood, although he thought she was a boy at the time as he vaguely remembers her. A few times Issei was invited to go to church with her family. On occasions they would stay over at each other's houses, one of these visits when Issei slept over at Irina's, she kissed him while he was sleeping. Eventually, Irina moved to England due to her father's job.

Sometime during his childhood, Issei met an old man who told him and other children stories about breasts, which eventually led to Issei's fascination with them and his perverted tendencies.

He attended the same middle school with Matsuda and Motohama and the three of them started attending Kuoh Academy one year before the story, and have come to be known as the Perverted Trio to just about the entire school.

## **Powers & Abilities**

**Demonic Power:** Issei has all the powers common to Devils, but his was lower than children, leaving him unable to travel using magic circles. It can be enhanced through promotion to Bishop or Queen. However, his training with Tannin afforded him sufficient demonic power to do so. It was that his demonic power without his armor is a at a level of a High-Class Devil, while in his Crimson Armor his power is Satan-Class, and in his Diabolos Dragon God form, it was stated to be Transcendental-Class.

* **Dragon Shot** (魔力弾ドラゴンショット, *Doragon Shotto*): One of Issei's signature moves, where he releases a beam of concentrated demonic power. It is often used in tandem with Boosted Gear to increase its destructive potential, once destroying a mountain. He developed a small scale version meant to knock out humans and lessen the damage done. Sirzechs' Power of Destruction inspired him to redirect his Dragon Shots, thus controlling their path, which he used against Cao Cao, and the Jabberwocky.

* **Dress Break** (, *Doresu Bureiku*): Issei's second signature move, which he mainly uses against women. As its name suggests, this move allows him to "strip" woman by first coming into contact with them, concentrating his demonic power, then snapping his fingers to activate one of two effects.
	+ **Ver. B (Body):** This move is used to "strip" women by destroying their clothes and/or armor.
	+ **Ver. A (Astral):** This move is used to "strip" women by destroying the effects of spells or abilities that have been used against them.

* **Pailingual** (, *Pairingaru*): Issei's third signature move, which allows him to "talk" to women's breasts after creating a "space". As such, it is a useful move as it allows him to learn his opponents' plans by asking their breasts, however, complaints from females from other peerages caused Rias to ban it in Rating Games. A drawback is that if a woman strips in front of him and informs him about her plans hinders Pailingual. In his D×D Form, it is powerful enough to cover an entire island and combined with **Penetrate**, it can talk to a powerful being's breasts.
* **Flame Blaze** (, Fureimu Bureizu): Due to Tannin's training, Issei learned to breath flames using Boosted Gear. First, he inhales, filling his lungs with air and produce a small flame in his stomach, then uses **Boost** and **Transfer** to enhance it, then breathes massive flames from his mouth. He can widen his dragon flame to the point that it can engulf the whole sky as shown in his battle against Cao Cao.
* **Summoning:** Issei can summon his familiar, Ryuuteimaru.

**Dragon Aura:** Due to possessing Boosted Gear, then having his left arm turned into a dragon, Issei has a small amount of dragon aura. Training with Tannin increased it, to the point of dealing minimal damage, while using Boosted Gear.

**Immense Strength:** At first, he was weaker than devil children, but training in the mountains and powered up using Boosted Gear lets him rival High-Class Devils, able to combat Riser's servants. Tannin's training made it possible for him to erase a mountain after donning Scale Mail; outclassing Diodora empowered from Ophis' snake.

Having awoken Triaina, and Crimson Armor, Azazel stated no one among the Young Devils aside from Sairaorg, Sasuke and Arata can fight him, equaling an Ultimate-Class Devil.

From Sun Wukong's training, then upon awakening Diabolos Dragon, he overpowered Rizevim, then managed to defeat Apophis.

Issei grew strong enough to the point that Baraqiel couldn't defeat him without it, then fight against Dulio and Thanatos, the strongest among their particular groups, defeating the latter.

He fought and bested Vidar, donned in his dragon armor. Ddraig noted the Crimson Armor reaches Satan-Class, while Pseudo D×D God reaches Super Devils, defeating Rias using Balor Princess.

He overpowers Angra Mainyu by using True D×D, then Hades after teaming up Vali and Team D×D, now being recognized as a Super Devil.

**Immense Durability:** Issei was originally very weak and vulnerable, easily hurt by the simplest attack. Through the use of Promotion, he can increase his defense.

After his training with Tannin, where he was forced to survive Tannin's continuous assault, Issei's durability greatly improves, along with his daily training further enhanced his durability to the point where his body could withstand continuous usage of the Boosted Gear which he couldn't do so in the beginning.

In fact, Issei's durability has been proven several times against opponents like Arata Mitsuzuri, Sairaorg Bael, Cao Cao, Grendel, and many others.

Issei can endure Baraqiel's Holy Lightning and continuing to fight despite the intense pain.

Issei can withstand Vidar's attacks even when he is wearing his Ragnarök Earth Berserk armor and even his signature move; *Fimbulvetr Shot*, the impact of which sent Issei crashing onto artificial Yggdrasil.

* **Flame Resistance:** Because of his training, Issei has also developed a high degree of resistance to fire attacks, so that only the most powerful flames, such as those of a Dragon or the Phenex Clan, can injure him.

**Immense Speed:** Through the use of Promotion, Issei can increase his speed. In his Balance Breaker state, he can use the booster to further increase his speed. In his DxD Form, he was able to appear in front of Rizevim before he can react. He was able to keep up with Vidar in his Ragnarök Earth Berserk. In his Pseudo-Diabolos Dragon form, he was easily able to keep up with Yuuto Kiba, who is famous for his exceptional speed, until Kiba revealed his Drag Knight Boosters.

**Immense Stamina:** Issei originally possesses average stamina. After being reincarnated into a Devil along with his daily training with Rias, Issei obtains more stamina to use the Boosted Gear. Following his training with Tannin in the Underworld, Issei obtains even more stamina, that he could use when in Balance Breaker. He eventually obtains enough stamina to activate his Scale Mail without a countdown. In Volume 23, he was able to keep fighting at his best throughout the whole two-hour Rampage Ball Rating Game.

**Dragonization** (龍化, *Ryū-ka*): Having sacrificed his left arm to Ddraig, it transformed into a dragon's arm, becoming immune to blessed items.

**Master Hand-to-Hand Combatant:** More than a martial artist, Issei is a brawler, most notably improved from his training with Kiba and Koneko.

Combined with Boosted Gear, he could hold his own against Riser's three Pawns and Rook.

Prior, his tactics involved head-on clashed, proving, barely effective against Vali; however, Tannin's intense training, honed his combat skills, letting Issei face far stronger enemies, through donning Scale Mail; cornering Kuroka, then overpowered a snake-enhanced Diodora.

Usual training, then donning Triaina and Crimson Armor allowed him to go toe-to-toe with Sairaorg, an extremely powerful Devil and master martial artist in a fistfight, while he'd donned the Lion's Armor.

He improved most from Sun Wukong's training, to where he fought Rizevim, a Super Devil, activating DxD.

He fought Baraqiel with Crimson Armor, who infused his strikes with Holy Lightning.

In DxD, allows him fight Vidar, who excels in a kick-based martial art, enhanced through Ragnarök Earth Berserk.

His experience and combat skill allows him to overpower Gressil, until he started using Resistance to make him more resilient to attacks.

**Expert Swordsman:** Though Issei isn't as skilled as Sasuke, Kiba, Xenovia or Irina in swordmanship, he has learned the basics from Kiba, and how to channel elemental magic through weapons from Sasuke, which has continuously been improved from regular training sessions.

As such, he can wield Ascalon as an arm blade extension of his Boosted Gear allow him to cut off Cao Cao's arm during their first fight in Kyoto.

Issei could deflect strikes from the strongest Grim Reaper Thanatos' scythe using Ascalon, then fought Vidar using both it and Ascalon II.

Issei develops a technique to shoot out his swords at his opponent enhanced by using both *Boost* and *Penetrate*.

Issei could fiercely clashed with Kiba's superior swordsmanship with Gram, blocking its strikes with Ascalon.

His skills has allowed him to wield all three Ascalon against Angra Mainyu, even using feints against him before stabbing him with his Tail Blade.

**Skilled Tactician:** Though outsmarted and considered an idiot, Issei has basic tactical knowledge, focused on surprising opponents. He carried holy water and a cross to counter Riser's Immortality; then overcharged Vali's wings after transferring power to them, breaking his armor using Ascalon. Issei acted as the Kyoto Team's leader, letting them face the Hero Faction; Kiba mentioned despite being simple, his orders let their group properly fight and defend themselves. Issei used Dividing Wyvern Faeries to in a unique manner to combat Euclid, who'd outmatched him in Crimson Armor. Against Kiba, he transferred power to him, thus making him lose control of his armored boosters; then taking advantage of the fact Rias wasn't familiar with his Nyuutron Beam Cannon, surprising and defeating her. Issei is currently learning Rating Game tactics from Ravel. Noted by himself that unexpectedness and explosiveness are his and his team strength.

His show has gained him countless fans such as Le Fay, Bennia, Millicas, Lirenkus, Natsume and Balberith.

**Skilled Dancer:** Due to being taught by Venelana Gremory, Issei became skilled in social dancing, able to coordinate with Rias in dancing well enough to pass the dancing trial in the ruins of connection

## **Equipment**

**Boosted Gear** (赤龍帝の籠手ブーステッド･ギア, *Būsuteddo Gia*): Issei's Sacred Gear and main weapon, among all the original 13 Longinus, which holds the Welsh Dragon, Ddraig's soul, making it a Mid-Tier Longinus. A left-handed red gauntlet that doubles his powers every 10 seconds until he reach his limit, letting him rival High-Class Devils, holding the potential to kill god if mastered. He later gained the ability to **Transfer** the multiplied power into a person or item, even parts like his eyes for enhanced vision. Issei later awakened **Penetrate**, letting him bypass all defenses like Rizevim's Sacred Gear Canceler, letting his attacks make contact; transferred into his eyes lets him see through anything, even woman's clothing.

* **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*): Boosted Gear's Balance Breaker creates a red dragon armor, which became his main combat form. Issei activated an imprefect version twice; the first time via a sacrifice lasting 10 sec; then again using a bracelet from Azazel, lasting 15 min. He achieved a perfected one from Tannin's training, but reached it from poking Rias' breasts to trigger it. In Scale Mail, Issei is strengthened to the point of erasing a mountain and Kuroka's spatial barrier using a basic blast; and can use **Boost** without the limiter. At first, he could use his boosters for enhanced speed and temp. flight; then gained retractable wings after using Juggernaut Drive, as well as its using the Pteranodon-like claws as arms.
* **Dividing Gear** (白龍皇の籠手ディバイディング・ギア, *Dibaidingu Gia*): The Boosted Gear version of Divine Dividing, caused from Issei installing one of its jewels into the right gauntlet during the initial battle against Vali. A white gauntlet, different from the red, granting him Albion's division and absorption powers. It, however, reduces Issei's lifespan, because of the Heavenly Dragons' contradicting natures and was banned by Azazel. However, after Ddraig and Albion reconciled with one another, thus gaining access to the **Dividing Wyvern Faries**, Dividing Gear became unusable.

* **Juggernaut Drive** (覇龍ジャガーノート・ドライヴ, *Jagānōto Doraivu*): A form unique to Boosted Gear and Divine Dividing, which releases the seals placed on the Heavenly Dragons temporarily granting the user immense power rivaling God, however, at the cost of his sanity and lifespan. Issei indirectly activates an incomplete Juggernaut Drive after believing that Asia was killed by Shalba with his negative emotions overpowering him thus triggering its activation. In this state, his Scale Mail becomes more organic appearing more like a miniature dragon, creating dragon arms and blades from the gems. Issei's immense power and speed allowed him to completely overpower Shalba,which makes his movements almost impossible to follow.
	+ **Longinus Smasher** (ロンギヌス・スマッシャー *Ronginusu Sumasshā*): Its finishing move and one of his most powerful attacks, which opens a hidden launcher on his chest before releasing an enormous amount of aura of immense destructive power. Ddraig described it as a forbidden power he shouldn't have, which can change the environment, if shot on land, then the entire area would vanish, and if shot in the air, the aura will dye the sky red.

* **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*): The Illegal Move Triaina is a specialized technique used by Issei Hyoudou that changes his Scale Mail armor into three different forms based on the Evil Pieces system.
	+ **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*): Triaina's Knight form. In this form, Issei possesses enormous speed that far surpasses Sairaorg's speed, but to make full use of it, Issei must shed his excess armor, causing it to become thin to the point where it has low defense, making him vulnerable to powerful attacks.
	+ **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*): Triaina's Rook Form. In this form, Issei possesses a massive amount of power and defense but has a low body maneuvering speed because of the massive, thickened armor.
		- **Solid Impact** (ソリッドインパクト, *Soriddo Inpakuto*): It's respected finishing move that delivers a punch that has its power and speed increased by nailing the percussion hammer located at his elbow.
	+ **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*): Triaina's Bishop Form. In this form, Issei possesses an enormous amount of demonic power, which he applies it to the two cannons at the back of his armor.
		- **Dragon Blaster** (ドラゴンブラスター *Doragon Burasutā*): It's respected finishing move that is a severely boosted equivalent of his Dragon Shot capable of leveling battlefields and briefly warp space-time. The drawbacks to that the amount of time it takes to charge the cannons and stamina lost with each shot.

* **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*): The Scale Mail's Queen form that is achieved by gaining the "True Queen". This form 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. In this form, Issei is capable of using enhanced versions of the Illegal Move Triaina's abilities. This form, however, is still unstable and requires mastering the three forms of Illegal Move Triaina to stabilize its powers. Issei can now enter True Queen without having to chant, and due to Diabolos Dragon God, its power has been increased.
	+ **Solid Impact Booster:** By morphing one of the armor's gauntlets into Welsh Dragonic Rook's, it allows it for an enhanced version of Solid Impact. It can also be used in tandem with Ascalon to deal further damage to Dragons.
	+ **Crimson Blaster:** An enhanced version of Welsh Blaster Bishop's "Dragon Blaster" that shoots a powerful beam from the wings of the armor.
	+ **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*): Originally taking the form of **Dividing Gear**, a white gauntlet on Issei's right hand which he obtained in his initial battle against Vali. Issei placed one of the jewels on Vali's armor to him, creating the Dividing Gear which allows him to use Albion's dividing powers. It, however, reduces Issei's lifespan and thus was banned by Azazel. Issei is no longer able to use Dividing Gear after gaining a new ability that allows him to create small white Wyverns from the gems of his armor that can not only **Divide** but can also **Reflect** incoming attacks. Unlike the Dividing Gear, It only requires Issei's stamina rather than reducing his lifespan. Issei manages to change the white Wyverns red at will where they are able to use Ddraig's powers of **Boost**, **Transfer** and **Penetrate** instead.
		- **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*): 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.
		- **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*): Issei also made use of the red Wyverns to attach themselves on Xenovia to create her own variation of the Scale Mail.
	+ **Longinus Smasher:** Issei gains access to this ability when the Red Wyverns used **Boost** on him while in this form. An ability initially available to Juggernaut Drive that from the chest appears a launcher that fires a powerfully destructive beam. This, however, leaves strong fatigue on Issei as it drains a lot of his stamina and depending on how one uses it, it can change the environment. Due to its immense power, this ability has a very long recharge period, lasting at least a month.
	+ **Tail Blade:** Using the Ascalon II Prototype, Issei with his tail of his armor can attack with its blade and lengthened the tail towards his enemies at high speed.

* **Diabolos Dragon God** (龍神化ディアボロス－『D×Dドラゴン』・Gゴッド－, *Diaborosu Doragon Goddo*): An upgraded form, which is the result of Issei releasing Ophis' power within him, causing his Scale Mail to turn crimson and black, two pairs of dragon wings, and ∞ on all his gems. In his form, his **Boost** is changed into **D∞D**, letting him overpower Rizevim and his Sacred Gear Canceller. However, Issei can only sustain it for a short period, causing severe pain and complications making even death pale in comparison. After the Evil Dragon War, Ophis adjusted it, removing the "Infinite" and named it Pseudo-Dragon Deification, but he can only maintain if for three minutes, lessening the time to ten seconds if he attacks or defends. In Vol 25, due to drinking the simplified Amrita, Issei can maintain it for eighty-eight minutes. In True Vol 4, after recovered his sexual desires, Issei unlocked the True-Dragon Deification after Great Red's flesh resonated. In this state, Hades stated his power was greater than his Pseudo Diabolos Dragon with the aura of a devil and dragon.
	+ **Infinity Blaster** (インフィニティ・ブラスター, *Infiniti Burasutā*): A further enhanced version of Crimson Blaster, the wings contain cannons that shoot out a powerful blast of red and black aura that leaves even Rizevim injured to an extent that his body is almost fatally damaged. By using it, DxD G's time limit of three minutes is cut down to ten seconds. After drinking miracle drug Amrita, Issei has overcome this weakness and can maintain his armor after shooting Infinity Blaster.
	+ **Longinus Smasher** (ロンギヌス・スマッシャー, *Ronginusu Sumasshā*): The form is not only capable of this move, but the blast it shoots out has been enhanced with the power of infinity, delivering further damage. It can also be used in tandem with the Infinity Blaster, fusing the two blasts into an even more powerful attack.
	+ **Blazing Inferno of Scorching Flames** (燚焱の炎火いつえきのえんか, *Itsu Eki no Enka*): An ability that was sealed by the God of the Bible, which Issei managed to unlock upon using his DxD form for the second time in Vol 21. Issei releases a powerful breath of fire that can incinerate anything, flames that never go out once ignited as they continue to burn even after being reduced to ashes and can probably burn the soul until nothing remains. The only existences known to be immune to these flames are Albion, Ophis, and Great Red. Its area of effect can cover an entire island.
	+ **Partial Pseudo-Dragon Deification** (部分龍神化, *Bubun Ryūjin-ka*): In Vol 23, Issei can perform a partial Pseudo-Dragon Deification on his armor, letting him channel his dragon god aura to some extent, but still lessens the stamina consumption. He could channel it into his left arm, letting him strengthen his various techniques such as Dress Break, Solid Impact Booster, and Dragon Shot; through transforming his wings using this allows him to move at greater speed.
	+ **Dress Break DxD** (洋服破壊ドレスブレイク・龍神式ディーディー, *Doresu Bureiku DīDī*): By using his Dragon God aura, Issei can increase his range that halts a female target’s movement, and by strengthening his left hand he can destroy their clothes without even touching them.
	+ **Red Dragon Emperor Ddraig Manifestation** (赤龍帝ドライグ顕現, *Sekiryūtei Doraigu Kengen*): Due to drinking the miracle drug Amrita, Issei gained the ability to summon Ddraig into battle after the [8] countdown on the right gauntlet reaches zero.

**Pawn Piece** (の, *Pōn no koma*): Due being the possessor of Boosted Gear, Issei needed to be reincarnated using eight Pawn Pieces, granting him more power than a normal pawn. As a Pawn, he can promote to either a Queen, Rook, Bishop, or Knight. Since his Pawn started adjusting to Ddraig's power, four of his Pawn Pieces turned into Mutation Pieces with different values due to Illegal Move Triaina and Cardinal Crimson Promotion, then the rest turned into Mutation Pieces due to Diabolos Dragon, a phenomena that even their creator couldn't believe.

* **Promotion** (プロモーション, *Promōshon*): Being a Pawn, Issei can use the promotion to temporarily gain the traits of a Queen, Rook, Knight or Bishop. In Volume 8, after Ajuka Beelzebub rewrote Issei's Evil Pieces, Issei can now use Promotion anytime and anywhere without the King's permission.
* **Castling** (キャスリング, *Kyasuringu*): Upon becoming King of his own peerage, Issei gained the ability to use this move, which allows him to swap locations with one of his Rooks. He first used it in his match with Baraqiel to escape a sealing barrier by switching with Rossweisse.

**Ascalon** (アスカロン, *Asukaron*): Issei's second weapon, received from Michael, having been through a ritual by the Three Factions' leaders so he could wield it despite not having the light attribute, and being a dragon host. It was stored in Boosted Gear, letting him extent Ascalon from the gauntlet, and being imbued with Ddraig's power, resulting in an enormous boost in power. Not being a swordsman himself, Issei often channels its dragon slaying powers into his punches, making it easier to harm dragons, and could infuse it into his Crimson Blaster. He could endow Ascalon with **Boost** and **Penetrate**, the effects lasting even after launching it as a projectile at Vidar.

**Ascalon II** (アスカロンII, *Asukaron II*): The second version of Ascalon. A long sword that releases holy aura, but is more of a dragon sword rather than a Holy Sword. Issei keeps this sword within his right gauntlet that was free.

**Ascalon II Prototype** (アスカロンII プロトタイプ, *Asukaron II Purototaipu*): The initial prototype model of Ascalon II that Issei used. Due to being created for Issei's use, other people cannot use it which is why the Vatican team that created it left it to him. Although it does not have the same ability as Ascalon II, it is still quite strong. Issei fused it to the tail of his armor to create the Tail Blade ability to suprise enemies with a third arm.

**Benihime** (紅姫, *Crimson Princess*): Issei's third weapon given to him by Shinano.

A blade described by Akio as "not nice", it is a weapon with a female spirit owned by a male. When sealed, Benihime is a beige-colored *shikomizue* (a blade hidden inside a cane) with a curved handle and silver base.

As the blade resides in a cane, the cane's handle is still the hilt and the shaft is the sheath, allowing it to still operate like other sword.

The shaft's base bears a Gokon Tekkō emblem on the bottom, which can separate souls from bodies by pressing the mark to it.

Back when Akio was still in the Gotei 13, Benihime was sealed in an average-sized katana form, with a black sheath worn under Akio's sash.

It had an oval-shaped tsuba, with a snowflake-design embossed in it, and a black hilt-wrapping.

* **Nake, Benihime** (啼け紅姫, *Sing, Crimson Princess*; "*Scream*"): This technique fires particularly strong and destructive crimson-colored energy blasts. The energy flows out of the blade and fires in the arc of the sword's swing. The technique is capable of taking on a point-blank Cero from an Espada-level Arrancar by dissipating it with a blast of equal power. He can charge up this technique to deal considerably more damage.
