Gressil was one of the hundred thousand artificial Devils that were created by Hades using the flesh of Lilith and the Book of Lucifer.


Gressil is a young man about two meters tall giant with black hair.


Gressil enjoys fighting strong opponents and causing damage to others in order to show his power. After winning his matches in the Rating Game tournament, Gressil started to become more arrogant in order to prove his superiority, which made him far rougher than Balberith.


Gressil was born in the Realm of the Dead, created by Hades with Lilith’s flesh in order to use him for his army in opposition to D×D. At some point, he joined Team Black Satan of Darkness Dragon King under the leadership of Zeno to participate in the Azazel Cup.

Gressil was mentioned in Volume 24, who has the power above Satan-class and may become a Super Devil if his conditions are correct. Under Hades’s orders, Gressil became a member of Team Black Satan of Darkness Dragon King to join the Azazel Cup, under the leadership of Zeno. He and his team fought against the Asura prince Mahabali and his team, emerging victorious after taking the flag in the Rating Game.

Gressil was mentioned by Verrine in Volume 25, stating their current goal to make him and Sonneillon strong as her and Balberith.

Gressil officially made his first appearance in True Volume 2, offering Balberith to walk with him and Sonneillon during their free time, but he refused. Gressil became annoyed with Balberith continuing to watch the Oppai Dragon show to study about Issei Hyoudou and asked again to walk with him and Sonneillon so they can pick a fight with people, but Balberith told to do as they please, which made them leave in frustration. Gressil and his team were up against Team Babel Belial that was led by Diehauser Belial in the first match of the main stage, but they were defeated because Balberith was using Issei’s Oppai Dragon fighting style, which made Gressil angrily asking him the meaning of this and his team also questioned their ace member, Gressil and Sonneillon were dissatisfied and were about to go on a rampage, disappearing in the end.

In True Volume 3, Gressil and Sonneillon attacked Issei and his group at Kyoto by wishing to defeat Issei as a commemoration before they fight Emna. He charged his aura to his hand and charge towards Issei, but managed to dodge by changing into his crimson armor and received a punch to the face, finally realizing why they been told not to engage the members of DxD like the Two Heavenly Dragons, Cao Cao, and Vasco Strada. Gressil began to charge towards Issei barbarically, but he dodge his attack and ended up destroying a two-storied shopping store in the process, but he continued to engage Issei in combat and managed to destroy his Crimson Armor and was later struck by Akeno’s Holy Lightning, but didn’t suffer much damage. Gressil tells Issei that among the members of Black Satan of Darkness Dragon King, Sonneillon is the worst because when things don’t go as he planned and admit they are attacking them so they can get more experience. Seeing Issei summon his Ascalon, Gressil dodge his attempt to slash and heightened the aura on his hand to punch Issei, but he was struck on his left shoulder by Issei’s new ability Tail Blade and was later blasted away by Issei’s giant Dragon Shot. Despite the damage he was taken, Gressil continued to walk and tells Issei that his body has remembered a part of it and charges towards him, as Issei fired his Dragon Shots and later used his Tail Blade, Gressil became immune to his attacks as he tells him that his body remember his attacks and if his power does not exceed Satan-class, they won’t work on him. Gressil prepared to do a headbutt against Issei as he defended himself, later he was sent flying by Issei’s boost enhanced Dragon Shot, but continued to fix his stance and was struck by Akeno’s Holy Lightning again but was unharmed by it, which is revealed because of his specialty Resistance. Sonneillon yells at Gressil to remove their limiter as he is angered by Yuuto, Rias, Kunou and tells him that the higher-ups will forgive them as long as they don’t destroy Kyoto, leaving Gressil to agree as they remove their limiters to increase their power, nearly destroying the Sunshower barrier until the Hero Faction arrives, forcing the duo to retreat for now.

During the battle in the pseudo-space, at the west side of the pseudo-barrier space that resembled Urakyoto, Gressil along with a group of artificial devils engaged the Slash/Dog team in battle as Gressil fought against Tobio Ikuse. Gressil revealed that he wanted to fight Cao Cao and Issei as if he fought against them, he could become a Super Devil as well as surpass Balberith and Verrine. When asked by Tobio what he intends to do once he surpasses them, Gressil revealed that he just wanted to rampage and fight to cause chaos, which disgusted Tobio as the two began to fight. During the fight he became frustrated that he couldn't damage Tobio due to his darkness aura, which dispersed Gressil's attacks as Tobio taunted him that only a true Satan-class or God-class could damage him. Gressil was defeated by Tobio when his Resistance failed to counter Tobio's blade as Tobio himself can alter the wavelengh of his blade, bypassing Gressil's Resistance and dealing a fatal blow. As Gressil bemoaned that the fact he couldn't become like Balberith and Verrine, Tobio replied that it takes more then power or demonic power to become a true Super Devil, as Tobio finished him off.

Powers & AbilitiesEdit

Immense Demonic Power: A special case among the hundred thousand Devils created by Lilith, Gressil’s demonic power is above Satan-class and he has the potential to become a Super Devil.

  • Resistance (耐性, Taisei): Gressil’s signature ability that gives him a nigh-impregnable resistance to any damage he experiences, potentially working even on Ddraig's Penetrate had Gressil the chance to receive it. While it could turn Gressil resistant to numerous attacks in one go if they had the same aura, Tobio Ikuse could counter it by continuously changing the aura wavelengths of his blades.

Immense Strength: Gressil’s strength has been proven he was able to defeat Ultimate-class Devils and several Low-class Gods in their Rating Games in the Azazel Cup. In True Volume 3, even with a limiter on, Gressil was able to fight on par with Issei in his Cardinal Crimson Promotion armor (a Satan-class combatant himself) and Akeno Himejima. Later, after releasing his limiter, he was capable of briefly holding his own against Tobio in his Abyss Side Balance Breaker; Perfectus Tenebrae Lykaon et Fortis Densus Laelaps, who noted that Gressil quickly became stronger the more he fought despite eventually overwhelming him.

Immense Durability: Aside from his Resistance, Gressil is incredibly durable on his own. Without becoming weakened, he could take several attacks from Issei in his Cardinal Crimson Promotion and even Akeno's Holy Lightning, which has properties lethal to Devils.

Immense Speed: Gressil was fast enough to keep up with Issei using his Crimson Armor and could also dodge several attacks from Tobio in his Abyss Side Balance Breaker. Despite this, Issei described him as not being particularly fast (albeit this was Gressil with a limiter on).

Master Hand-to-hand Combatant: Despite lacking any proper training or experience, Gressil has shown to be a formidable combatant. Despite being a Power-type much like Issei and Xenovia, he's considered a genius as he was quickly able to adapt to and match Issei, an experienced hand-to-hand combatant, despite the latter initially outclassing Gressil due to his many openings.

Flight: Being a Devil, Gressil can fly using his devil wings,


  • Gressil's comes from the demon Gressil who was the third prince of Thrones, who tempts mankind with impurity.
