Invading the Hades Cathedral
He is introduced along with Scorpio Kardia , appearing as part of the Athena army led by Sagittarius Sysiphus waiting for the barrier surrounding the Hades castle placed by the Underworld King himself to be broken in order to be able to enter. After Kardia expresses his boredom and thirst for his prey due to having to await orders, Dégel reveals to him that the castle had already been penetrated by another much to Kardia's surprise. After Hakurei manages to seal the soul of Hypnos, he is killed by Hades, whose barrier had now grown much more powerful with his presence. Sensing the disappearance of the God of Sleep's Cosmos, yet the intensity of said barrier, Dégel concludes that Hades must have descended again into his castle.
Mission To Bluegrad
He was at first involved in an investigation regarding Bluegrad's Blue Warriors and the seal of Poseidon. In Bluegrad both him and Scorpio Kardia found a way to Poseidon's submarine temple, known as Atlantis. There, Dégel watches his old friend Unity being killed by Rhadamanthys, in anger, Dégel attacks with Aurora Execution. Later, he uses Koĺtso, which creates rings of icy wind that circles the opponent's body limiting their movement, to stop Pandora. None of Dégel's attacks were effective against Rhadamanthys, but soon after Kardia mentions that he is surprised of Dégel's poor performance in battle due to Unity's death. The reason behind Dégel's failure was attacking out of rage instead of executing precise strikes. Being a Saint who uses freezing attacks, Dégel needs to concentrate as the basis of his combat style lies in stopping the movement of atoms, not destroying them.
Nevertheless Dégel finds out Unity was alive and had become a Marina General, one of the seven most powerful warriors of Poseidon. He refuses to fight his friend Unity, now wearing the Sea Dragon Scale. However, Unity tries to manipulate Dégel's movements with his coral in order to break Athena's seal and free Poseidon. While Unity attacks, Dégel realizes what has happened to his friend: Unity became desperate to save Bluegrad from the eternal cold, therefore he finds Athena's Amphora, the container of Poseidon's soul, and the Scales. He is then shown killing his own father and promising to make Bluegrad the greatest country and have it rule the entire world. Dégel is infuriated and freezes all the corals, then he uses Diamond Dust. Finally, Dégel realizes Unity will never give up his plans and decides to fight seriously. He says he will defeat his friend but would keep their promise alive. By using Aurora Execution Dégel freezes the whole sea that collapses Poseidon's statue. With that movement Unity was freed from the power of Poseidon.
Dégel succeeds in retrieving the Orichalum, a crystal that contains Poseidon's power, however, soon afterwards, it is stolen and partially broken by Pandora unleashing the true power of Poseidon into Seraphina's body. In order to contain that huge power of the Sea god, Dégel freezes himself, Unity's sister Seraphina and all Atlantis inside the Freezing Coffin . At this time Dégel reaches Absolute Zero. Thus he could prevent the world from being destroyed by Poseidon and entrusts Unity to take the Orichalcum to Sasha. In his last words Dégel says both he and Seraphina would watch over Bluegrad, the Earth and Unity, blessing his steps.
