Byaku of the Necromancer

•Most Resurrection: Byaku uses his abilities to summon the spirits of the dead, creating an area imbued with hatred and resentment where he is located. To his opponents, it seems as if a dark fog envelops the surroundings. When he decides it's time to attack, the dead restrain the opponent's body without him realizing it, leaving him completely immobilized. In this way, he can gather the dead in one place; they take the form of an imposing human skeleton covered in a dense black mist. Then, he raises his hand to signal the dead to attack. The skeletal figure transforms into a vortex of darkness and engulfs the opponent, who sees the faces of the dead screaming and trying to devour him. When the attack ends, the vortex disappears and the opponent's lifeless body falls to the ground.

Byaku and the Specter squadron approach the village, but before they can reach it, an Albafica trap activates and white roses fly towards them, piercing their bodies and draining their blood. Byaku watches his comrades fall defeated and realizes they've fallen into a Pisces trap, but before he can do anything, a rose strikes his back and ends his life. Hades' power begins to resurrect the Specters defeated by the Saints. Byaku and the group of Specters killed by the Bloody Rose return to life and notice that the barrier Athena placed to prevent their resurrection is weakening. One of the Specters informs Byaku that he cannot sense Minos' cosmos and begins to wonder if he was defeated by Albafica, but considers it impossible, as Lord Minos would never be defeated by a simple Saint. Hasgard of Taurus appears before them and informs them that Minos was defeated and that they too would die again. Byaku recognizes his opponent as a Gold Saint, introducing himself by name and asking if he intends to fight them all. Hasgard crosses his arms and the Specters charge at him, but are defeated and killed by a blow from the Great Horn. Dohko arrives on the scene and Hasgard tells him they must move the corpses inside Athena's barrier to prevent their resurrection. When Asmita of Virgo sacrificed herself to create the 108-bead rosary, Byaku and all the Specters who had died up to that point are sealed by the power of the rosary, preventing his resurrection for the rest of the conflict.

When the god Hades awakens in Alone's body, Byaku and the rest of the Specters gather in the cathedral to meet their leader. Alone orders the Specters to end the lives of Athena and the Saints, and asks Minos to gather a group of Specters and attack the Sanctuary to kill Athena and Tenma of Pegasus. Byaku is part of the troops accompanying Minos in his attempt to invade the Sanctuary, but before reaching the location they are intercepted by a small group of Silver Saints, who are cruelly murdered by Minos, while the rest of the Specters simply observe the scene. When they prepare to continue, they notice a path of roses appearing before them, and sitting on a stone pillar is Albafica of Pisces, who warns them that if they try to advance they will die from the poison of the roses. Two Specters ignore the warning and try to cross the path of roses, only to succumb to the poison. Byaku and Minos watch as the Specters are defeated by Albafica, who again warns them that if they continue, they will all die, but Niobe decides to fight him, as his ability allows him to combat the effect of the rose poison. Although Niobe has the power to challenge the Gold Saint, at the end of the fight he is defeated, therefore, Minos decides to fight his opponent and first destroys the path of roses with his Gigantic Feathers Flap. Minos manages to stop Albafica with his Cosmic Marionation and, realizing that the Gold Saint was trying to protect the town of Rodorio, orders Byaku and the rest of the Specters to attack that place first.

Byaku is a devoted subordinate to his leader Minos and shows great respect for him. He also seems quite confident in the global power of the Specters, as he shows no fear when facing a Gold Saint. However, this confidence led him to underestimate his opponent, resulting in his defeat along with the entire squadron of Specters he commanded.

He is a young man of average height and slender build, with long blond hair. His eyes have black pupils and a white iris.
