Jellal reveals that he wants to sacrifice Erza to resurrect Zeref. Before Erza gets absorbed by the lacrima, Natsu rescues her and knocks her out. Natsu and Jellal have a fierce battle that results in the death of Simon. This causes Natsu to eat the Etherion which fuels his rage. After Natsu defeats Zeref, the tower of heaven starts to implode. Erza decides to sacrifice herself to save Natsu by merging with the lacrima.
In Erza's vision, she sees a sad future for Fairy Tail as everyone mourns for Erza except Natsu. Her vision ends with Natsu holding her bridal style. He tells her that one should live for their friends; Erza agrees as she cries when her friends go out to embrace her.
Jellal tricks Erza by telling that he is a puppet of Zeref and he wants to die with her. As the two hug, etherion strikes down the tower of heaven revealing it's true purpose. It's a giant lacrima crystal tower that has absorb Etherion's magical energy. Jellal reveals that he and Siegrain are the same person and as Erza gets pulled in the etherion due to Jellal's magic, Natsu appears and pull her out. After a comedic moment between Erza and Natsu, Natsu punches Erza in her stomach knocking her out. Natsu tells Jellal that Erza is best when she's violent and strong and he and Jellal immediately fight.
During the battle between Jellal and Natsu, Natsu has made Jellal very angry when Natsu finds out Jellal needs his tower. Natsu infuriates Jellal by damaging the tower and making Jellal attack his tower. However, Jellal proceeds to use Altairis on Natsu, but Erza blocks Natsu which makes Jellal pause his attack. Yet, the impatient Jellal does not care anymore and uses Altairis on them. After the smokes has clear, Simon is standing in front of Erza and Natsu and he collapses right in front of Erza. As Simon is dying, he tells Erza he always love her because she is kind. When Erza cries out and Jellal laugh at Simon's death, the enraged Natsu smacks Jellal across the room. As Jellal recovers, he sees Natsu eating etherion. At first, Natsu's body cannot take in the Etherion, but Natsu finally powers up. Natsu unleashes all his fury on Jellal, and as soon Jellal tries to use the abyss break on Natsu, he stops because of a wound inflicted by Erza. Using this moment, Natsu finishes off Jellal.
Erza remembers that Porlyluscia gives her a glass eye and how she cries out of one eye. During her vision, Erza sees that her sacrifice brings a sad future to everyone because Natsu's disbelief causes everyone to shed more tears.
In the after note, Mashima explains that he wanted to stop Fairy Tail at its 10th volume, but due to many warm supports, he continued writing Fairy Tail. Also, Mashima explains how the Erza chapter parodies his former work, Rave Master and the foreshadowing of Erza's eye.
