Erza and Jellal grew up with the same past. They can relate to each other, but what about their present selves? Often, we have seen Erza and Jellal fighting as partners on the battlefield. We see how well they fight together and how it actually empowers them to fight harder regardless of the enemy’s strength. Erza and Jellal work wonderfully as partners without actually being partners.

Outside of the battlefield, we see that Erza and Jellal are able to read the other perfectly. Erza shows us that she can tell when Jellal is lying and Jellal shows us he knows how Erza feels. Jellal and Erza are constantly showing us how well they work together, read each other, and know about each other. Their relationship has been built over many years, on top of hardship and life’s cruelty, but it has held fast and become a concrete base on which they can stand together as partners. We can truly see how Jellal and Erza act as two halves of one whole after their many years of friendship and turmoil. How can they not be made for each other?

Throughout the series, Jellal is a continuous source of strength and empowerment in Erza. Even as young children, Jellal helped to ignite the fire within Erza to fight for the freedom of the slaves on the island. Despite the complications in their initial plan, Jellal did provide strength for Erza to become stronger than the slave that she believed she could only be. Erza did not have to be weak or take on the abuse of others. Because of Jellal, Erza was able to find strength in herself to protect her friends and become even stronger.

It is shown in the Tenroujima arc that Jellal is one source of Erza’s strength, alongside her other guild mates. This is but one instance when we see that Erza is powered by Jellal’s words. When she feels at her weakest, when the enemy has her beaten, Jellal’s words will always come to Erza to give her the power to defeat her enemy.

Time and time again, even though Erza acts as if she is tough, she finds salvation in Jellal when she needs it most. How many of us can say we have found the person who instills in us the power that we often forgot we have? Do you still need to be convinced that Jellal and Erza need each other?

Jellal is a troubled soul throughout most of the series. He is the type of person who has gone to Hell and back with very little reward except for guilt for his journey. When it seems like Jellal will be forgiven, his past forgotten, he is arrested after having helped Fairy Tail fight against the Oracion Seis for the crimes of his past. He is willing to give himself up, but it is Erza who bears the brunt of his pain through her tears.
The girl who seems to have no emotions except for seriousness actually breaks down into tears for Jellal. It is in this moment we see the extent of Erza’s feelings for Jellal. Yes, we as the viewer have felt the pull between both characters for many arcs, but it is in this moment that we can feel the intensity of Erza’s feelings! She takes on what should be Jellal’s feelings of cruel injustice, remorse, and dissatisfaction—feelings that Jellal does not allow himself to feel—and expresses her pain through tears.

Jellal has someone who will cry for him. Does that not say a lot about the relationship between Jellal and Erza as a whole? How many of us have found someone who will cry for us, regardless of whether we deserve the tears? What Jellal has in Erza is something clearly special.

Throughout the course of Erza’s life, Jellal is a being that stands on the forefront of her thoughts. Jellal exists in her secrets. He exists in her future. He will always be there. However, what some may not consider is the idea that Jellal gave Erza’s life purpose.

Even when Jellal had been controlled by Zeref, Jellal gave Erza a purpose: to sit back and watch what her sins wrought her. This may seem like a terrible purpose, but the guilt that Erza developed from being freed kept her alive, if only for the purpose of being forced to see what her freedom ended up costing her. While others would have turned to suicide, Erza sought out more power, which allowed for her to find a family in Fairy Tail which eventually led her to find a way to save her friends at the Tower of Heaven. This is just one of the many ways that Jellal contributes to what defines ultimately defines Erza.

However, the true scene in which Jellal gives Erza the most purpose is shown when Erza flashes back to the time she admitted to her friends that she does not have a surname. When he heard this, Jellal gives her the last name Scarlet after noticing her beautiful hair. Jellal confirmed Erza’s existence and gave her an identity. Although this scene is quite early on in season one of Fairy Tail, it really defines their relationship throughout the course of the series.

When most of us question our own life choices and our purpose of life, Erza has unwittingly found someone who gives her what everyone needs the most. Is that a sign of the perfect partner or what?

Above those four reasons, number five stands above the rest: Erza forgives Jellal of all his sins. It is no exaggeration to say that everyone hates Jellal. It is a reoccurring issue amongst many of the characters in Fairy Tail, old or new. Many of them have a valid reason, yet they do not have an easy time accepting Jellal for all of his evil doing. It is only Erza who willingly accepts everything that is Jellal.

From the beginning, Erza never truly blames Jellal for his actions. She is constantly hoping to appeal to his human side that she knows exists or blaming herself for the problems at hand. Erza was always willing to accept Jellal, sins and all. Even now, Jellal cannot forgive his own sins, but Erza does. She knows everything that he has done, but she loves him despite it all. At this course in the series, Jellal is seeking redemption for his terrible deeds throughout the course of his life. Erza does not wish to make him bleed for his sins. Erza offers Jellal her forgiveness because that is what he needs the most: someone who will truly forgive him.

Aren’t we always looking for someone who will forgive us for all we have done? Are we not seeking someone who will accept us in spite of all our transgressions? This is what makes Erza perfect for Jellal. She is what many of us hope to find in a partner.
