Issei Hyodo

Voiced by: Yūki Kaji

Issei Hyodo (兵藤 一誠, Hyōdō Issei) is the male protagonist of the series. He is a pervert who has a habit of fantasizing, and is well known for being creepy at the Academy, but, in contrast to this, he is also surprisingly hot-blooded and hard-working. His first girlfriend suddenly kills him, but Rias saves him and brings him back to life as a Devil of her own clan, making him a member of the Occult Research Club. His rank is "Pawn" and his powers as a Devil are low-ranking, but on his left arm he wields a Sacred Gear called "Boosted Gear". He works hard day and night for the sake of his master and the highest-ranking Devil, Rias. His goal is to one day rise in rank into a high-class Devil so that he can gather his own servants and create his own harem.

Despite the fact that he is a pervert, he attracts numerous girls around him: Rias, Asia, Akeno, Koneko, Zenovia, Irina and Ravel. This is due to him wanting to protect and help them despite almost dying at the hands of his opponents. He is oblivious to the girls around him being in love with him. Later on in the series, Rias explains the reason why she cannot have any more Pawns other than him is because she had to use all 8 pawns to bring him back to life; however, the real reason is because of his Sacred Gear.

In the light novels, it is revealed that Issei's Sacred Gear has more capabilities then what has been shown before. The Boosted Gear is actually a forbidden Gear which starts of as a gauntlet at its first stage. While training and mastering its powers, the Sacred Gear will begin to spread throughout the body as armor. Once fully mastered, it is said to be able to kill a Satan or a God. This is because the armor doubles the user's power every 10 seconds without limit, the only restriction being the user's own ability to handle the power. Hence why Angels, Fallen Angels, and Devils fear this power.

In Volume 4 prior to the meeting of the three factions, he receive St. George's Dragon-slayer sword, Ascalon, from Michael. Due to his training in the Underworld with former Dragon King Taninim, he obtained a great stamina that he can use when he gained his Balance Breaker, which he does during his fight with Kuroka where he gained full-access to his Balance Breaker.

Issei's Sacred Gear, "Boosted Gear" (赤龍帝の籠手（ブーステッド･ギア）, Būsuteddo Gia, lit. "Crimson Dragon Emperor's Gauntlet"), is one of the Thirteen Longinus, where one of the Heavenly Dragons, Ddraig, The Red Dragon Emperor resides. Issei is nowhere close to mastering the Gauntlet, and as a result when he enters Juggernaut Mode, 99 percent of his lifespan is sacrificed, though he and Koneko managed to get it back. Later on, Beezlebub, one of the Four Satans (the original creator of the Evil Piece system), remodels Issei's piece so that he can use Promotion anywhere and at any time, regardless of if he has used promotion already. By using Promotion, he is able to use Knight, Rook, and Bishop ranks, and can achieve Illegal Move Trident (赤龍帝の三叉成駒（イリーガル・ムーブ・トリアイナ）, Irīgaru Mūbu Toriaina), which makes Issei's Balance Breaker Armor change to other forms using Promotion. In Knight Form, called 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), he possesses enormous speed that far surpasses Sairaorg's speed, but makes his armor thin where it has low defense; in Rook Form, called 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), he possesses massive power and defence but has a low speed because of its massive armor; in Bishop Form, called 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), he possess an enormous amount of magical energy in where he applies it in the two cannons at the back of his armor, but it takes time to charge. He later gains access to Queen Mode (known as 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)) in Volume 10 of the light novels, which is equally as powerful as Juggernaut mode. Juggernaut Mode is the full bodied armor of the Boosted Gear, the Scale Mail, which gives him the Balance Break ability.

At the end of Volume 10 of the light novels, Issei cannot hold back his feelings for Rias and confesses to her, calling her by her first name for the first time. She accepts his feelings in tears of joy and the two officially become a couple, although it seems none of the girls have given up (Akeno, Zenovia, Asia, Koneko, Irina, Reyville) on Issei. In Volume 11, Issei is promoted from low-ranked Devil to high-ranked Devil, and Rias' mother suggest that Issei and Rias get married.

Her rank among Rias's underlings is "Bishop". When Issei saved her from the Fallen Angels, she fell in love with him, and eventually with interventions from their leader Rias, moved in with him to live together at the Hyodo household. While the perverted side of Issei wants to do naughty things to her, his actual feelings towards Asia is a bit complicated, as he also sees himself as the protective guardian of the simple-minded, pure-hearted girl that Asia is, which in turn deters him from doing all the aforementioned things to her that he fantasizes about. Asia has a baby Sprite Dragon as her pet and familiar whom she named Rassei (ラッセー, Rassē), after Issei's name.

Although he calls himself Issei's friend, he is almost the complete opposite of the latter, sporting good looks, intelligence, and a pretty nice personality. However due to the events in his past, he bears an immense hatred towards the Holy Swords, as well as about everything and everyone associated with them. Much to Issei's dismay, the pairing of him and Yuto has become a hot topic between the girls in the academy.

In the light novels, it is revealed that he was a victim of the Holy Sword Project, where he was the only sole survivor. He became Rias' servant when she saved him from death, and swore to extract his revenge on those who treated him as a test subject and disposed of his friends.

The calm and collected member of the duo, she was sent by the Church along with Irina to retrieve the stolen Excalibur swords. She only speaks when it is necessary and prefers not to get involved into problems that do not concern her. Unlike Irina who is an artificial Holy Sword user, she is a natural-born user, which is evidenced by her being the sole wielder of Durandal.

The name of her sword is "Excalibur Destruction" (破壊の聖剣（エクスカリバー・デストラクション）, Eksukaribā Desutorakushon), which has the ability to unleash pure, destructive power that can easily shatter anything it comes into contact with.

Later on in Volume 3 of the light novels, she shares a very close relationship with Asia, as she is touched by the latter's kindness, and later apologizes to her for calling her a witch. As the series progresses, it is shown that Zenovia has romantic feelings for Issei due to his determination to protect his comrades even if he gets injured by doing so. She also emits a scary aura whenever the other girls are getting more closer to him. She later moves into the Hyodo residence in Volume 10. As she was raised in a church, she lacks common sense that normal people would have, shown when she once took a box of condoms to school.

These 4 parts of Vritra's soul have different appearances and have been collected and sealed in Saji's Body. Azazel hypothesized that due to contact with Issei, Vritra's consciousness appeared and might possibly unify all the different Sacred Gears because the other Sacred Gears melted together and Vritra's consciousness was restored. Vritra possesses a wide range of special abilities. Though its power might be the lowest amongst the Dragon Kings, Vritra is the king of techniques in terms of variety and unconventionality.

Voiced by: Takehito Koyasu

Introduced as Rias's fiance (but that changes when his ulterior motives are revealed and Rias's disgust of him), Raiser is a high ranking devil. Because the Phenex family has inherent powers that are equivalent of the legendary creature, Phoenix (which the family's name is also derived from), Raiser's abilities reflects those of a phoenix, where he can regenerate from almost any injuries immediately and is practically impossible to defeat. It is said that the Phenex Family's tears sell for a high price because of its powerful healing abilities, resulting in the Phenex Family's immense wealth. As a high-ranking devil, Raiser has his own group of a full fifteen servants, all consisting of females, something which Issei both looks up to and envies at the same time, and he sees no problem in making out with them in front of others, especially Rias and Issei. After being defeated by Issei, Raiser fell into a slump.

Sousou (曹操, Sōsō)

Sousou is the leader of Hero Faction and the wielder of the Ultimate-Longinus, "True-Longinus", the same spear that was used to kill Jesus Christ. Like his ancestor, he has the eyes to find people with good potential. He is a calculative and observant person, as he studies and research on his enemy before he battles them so he can read their movement and attacks. In Volume 9 he lost one of his eyes to Issei's attack, and later replaces the lost eye with Medusa's eye, granting him the ability to to turn anything to stone (this results in Vali calling him the "strongest human"). He is a technique-type who has polished his technique to utmost pefection. Because he is a human, he is physically weaker then Issei and Vali, yet in Volume 11 he singlehandedly takes down the Gremory and Vali groups while protecting Georg and Sameal. His Balance Break is a sub-species so it is much stronger than the actual Balance Break of the "True-Longinus". His Balance Break creates seven bowl size orbs around him, and his Balance Break has seven Sacred Gear abilities.

Originally from the Chaos Brigade, Sousou betrayed them when he stole Opfus, their leader's, power and sided with Hades, the God from the Realm of the Dead.
