Volume 16
While Naofumi is communing with the Spirit of the Shield, he is warned of a 'World Eater' who is the original enemy of the Legendary Weapons. This entity is so powerful that the heroes have no chance of winning in a direct fight so they must prevent it from entering their world. Both Kyo and Takt are revealed to be advance troops for this entity, trying to weaken the world's heroes. The Shield's power-up method was kept hidden by this entity and the Seven Star Gauntlets had been interfered with in the past.

Relationships

 * Vassal Wielders
 * Aultcray Melromarc XXXII (Trash): Trash is the father of one of Medea's soul fragments, Malty. As Trash had personally executed Malty the second time, via burning at the stake, he shows a heavy amount of emotional sorrow for his actions. As Medea had revealed the truth about Malty's existence, where she used an imitation of Witch's voice to state her fragment's rage over how her father executed her, this had caused Trash to hesitate until Naofumi had snapped Trash back to his senses, as he reminded him about Melty. Trash then began to show his first signs of hatred towards Medea as she revived Queen Mirellia and controlled her into leading her soldiers. While Medea had again begun begging for mercy from Trash, she had already long passed the limit to what could be forgiven, even if they were father and daughter, where Trash responded, "You are no daughter of mine! You dropped people into despair and laughed at them with scorn. You’re just… a devil pretending to be of my own flesh and blood!," thus showing that Trash had cut off any and all emotional ties to Malty as the father resumed to help everyone vanquish the malevolent goddess.


 * Legendary Heroes
 * Naofumi Iwatani: Her hatred of Naofumi, inherited from her fragment, Malty, is extreme because of the constant meddling in her affairs caused by the young Hero, as well as her suffering by his hand, regardless of the fact that said suffering was well deserved. She killed Naofumi immediately by erasing him from existence in every world and timeline, as well as the divergent world in which he existed, however, thanks to Arc, he survived, became a god himself and came back. Arc himself noted upon hearing about her method of killing him that "she really, really, wanted you dead, man." The deified Naofumi and Raphtalia promptly defeated her alongside the other Heroes and their allied forces. Ultimately, Naofumi reflected her all-existence erasing magic back at her, killing her in every world and divergent world that she existed in, then took her powers and used them to undo all the damage she caused before, all this after beating her with humiliating ease.


 * Others
 * Reincarnated: Medea's chosen warriors, whom she would manipulate to the point where the reincarnated delude themselves into believing that they were fighting for justice and that their enemies were the "embodiment of evil." As they were cornered, where they pleaded to their goddess for more power, Medea did not hesitate in killing them all simply out of the pleasure of seeing them suffer, as she deemed them no longer useful to her.
