In the end, it doesn’t seem fair, does it? Irene, who loved so much and gave so much for humanity, found herself continually mocked by the hands of fate. Irene didn’t get the chance to get to know Erza, to spend quality time together with her and to be a parent to her daughter. Irene was broken by the subjects of her love and cast down into a spiral filled with suffering and anguish eventually being overwhelmed by madness where she found herself driven by the desire to kill her own daughter. Since being imprisoned by her husband, it was moments of suffering followed by moments of suffering. Only at the end did Irene come to reclaim back the humanity slowly being lost within her rage. Still, it would have been inspiring and heart-warming if Irene had gotten the opportunity to be a mother and the chance to share her life with her daughter.
Despite the success in preventing Tartarus from nullifying all magic power on Ishgar, the cost of reaching such a point was felt by many, in particular, the Dragon Slayers and Gray. The truth behind the remnants of the Dragons and their attempts to prevent a repeat of history and the annihilation of their creation birthed from their mistakes unveiled the necessity of working together to defend against the inevitable future threat Acnologia poses to all creation. And within the shadows of that engulfing darkness, Zeref waits for the one capable of ENDing his suffering and setting him free from the prison of immortality. The flame demon known as E.N.D, otherwise fully known as Etherias Natsu Dragneel.
Reduced to nothingness and numbed of sensation, the world before one turns to darkness, yet within that formless stream of existence and space, the magic of one’s soul manifest into a light connecting their being to the endless depths of the world. Broken down and stripped of her five senses, Erza manifest her spirit into a light capable of residing within the flow of the world, ultimately awakening a sensation beyond form.
And so the wings of hope cast aside the clouds of despair and reveal the rays of light awaiting beyond such impending doom. Appearing before his son and resolving to open a path for his son to prevent the end of the world from culminating into destruction, he engages the Black Dragon, Acnologia.
And so the darkness thick in despair invades the skies and hearts sensitive to such terror find themselves shaken by the realisation of its appearance. Unexpected and inconceivable, the King of Dragons arrives in front of the humans and demons for a purpose yet to be revealed but one which will have serious repercussions for the fate and the state of the world.
