Issei Hyoudo

Issei Hyoudo was a native of Hellawes. The country, which was embroiled in constant war and strife, became the base of operations for a CCG cell operated by Investigator Arima, who recruited Issei and Rias Gremory to take part in a series of tests involving a Dragon Ball, giving the demon's already impressive power a large boost. While his wife received a number of magical enhancements, Issei acquired the ability to completely master the Boosted Gear, even when using Juggernaut Drive. When the CCG fell, the lovers joined the Homonculous Father to continue their quest for revenge on Edward Elric, but eventually switched sides and helped the Jump Force when they discovered Father's true intentions. Issei then fought in the Battle of Hellawes alongside all of the other Jump force members, but later sacrificed his own life to protect Sebastian Michealis and a civilian boy, much to his wife's grief.

Abilities
Demonic Power: Issei has all the powers and abilities common to Demons, including the power to cast spells. His demonic power was originally lower than a child's, unable to travel via magic circles but now he has sufficient power to do so. Through the use of Promotion, Issei can increase his demonic power.

Dragon Shot ( , Doragon Shotto ): One of Issei's signature moves. Issei fires a beam of energy by concentrating his magical powers. This move is usually used in tandem with the Boosted Gear to increase its destructive powers. He has also developed a small scale Dragon Shot that is meant for knocking out humans.

Dress Break ( , Doresu Bureiku ): The second of Issei's signature moves which he uses mainly against females. This move allows Issei to "strip" women by first coming in contact with them, concentrating his demonic power, then snapping his fingers to activate one of two effects. Pailingual ( , Pairingaru ): Issei's third signature move. Pailingual gives him the ability to talk to the breasts of all females. It is a helpful technique as it helps Issei learn his opponents' plans and strategies by asking their breasts.
 * 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.

Nyuutron Beam Cannon: Issei's fourth signature move. Nyuutron Beam Cannon gives Issei the ability to attach his Scale Mail's tail to a woman's breast and absorb their breast energy. This allows a powerful beam cannon to be fired as the result of breast energy being infused with Issei's demonic power. The color of his beam is pink in comparsion of his previous abilities. The woman's bust size is displayed in his gauntlet's jewel and the number determines how powerful the beam will be.

Immense Strength: Issei possesses incredible strength beyond that of most mortals.

Promotion: Being a Pawn, Issei can use promotion to temporarily gain the traits of a Queen, Rook, Knight or Bishop.

Flame Blaze: Issei can use Dragon Flames through Boosted Gear. He first inhales an amount of air to fill his lungs, then uses his demonic powers to produce a small flame in within his stomach and use Boosted Gear's ability to enhance it. While the air mixed the enhanced fire within his stomach, he breathed out a large stream of dragon flames from his mouth toward his enemies.

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.

Boosted Gear ( , Būsuteddo Gia ): Issei's Sacred Gear and main weapon. The Boosted Gear is one of the 13 Longinus which holds the spirit of the Welsh Dragon, the Red Dragon Emperor, Ddraig, one of the Heavenly Dragons. It is said to have the power to kill a God when fully mastered. Boosted Gear takes the form of a red gauntlet on the wielder's left hand that has the ability to Boost the user's power every 10 seconds without limit, and its sub-ability can Transfer the multiplied power to a being or object, it can even be used on certain parts of the user's body such as the eyes for enhanced vision. Later it gains the ability of Penetrate to bypass any defensive abilities that would otherwise prevent his attacks from landing, however, it does not negate the deactivation of Balance Breaker. Penetrate's effects can also be channeled through other parts of the body, such as the eyes, making it capable of seeing through anything, even women's clothing.

Boosted Gear: Scale Mail ( , Būsuteddo Gia: Sukeiru Meiru ): The Balance Breaker of Boosted Gear that creates a Red Dragon Armor and Issei's primary battle form.

Boosted Gear: Juggernaut Drive ( ,Būsuteddo Gia: Jagānōto Doraivu ): A form unique to the Boosted Gear and Divine Dividing. The Juggernaut Drive temporarily removes the seal placed on the Heavenly Dragons granting the user immense power. The Juggernaut Drive, however, causes the user to lose sanity while having their lives devoured by the power.

Ascalon (アスカロン, Asukaron): A Holy Sword is given to him by the Archangel Michael after some alterations, Issei was able to wield and merge the sword with his Boosted Gear and keeps it stored inside when not in use.
