Warning, a short chapter. Kind of sad though. Unedited, I just read it through once. 

You knelt at a gravestone with pebbles in your hands. You where here to pay your respects to your sister, Lisanna. You used rocks instead of flowers because rocks where immortal, flowers were not. 

The rocks symbolized that even though Lisanna wasn't with you anymore, you still thought about her, day and night.

You let a tear slip out of your eyes. Why did the world have to be so cruel? Why did they have to take Lisanna away from you?

You had always been mentally weak. You may be physically strong, but you were weak minded. That allowed your mind to become more insane by the passing day. 

Soon, you would not be the Y/n that everyone knew. 

Your siblings Mirajane and Elfman had tried to help you but you had pounced on Elfman and had tried to kill him for taking Lisanna away from you.

You had shifted into your Dragon Force form and had leaped at him, with an intention to kill. It had taken, Gildarts and the master to stop you from destroying Magnolia in your rage.

You started sobbing as you thought about the events that had occurred.

First, your dragon, then Lisanna, why did the gods hate you so much?

What had you done to them that made them spite you?

Why did everyone in your life leave you?

Either way, you were tired of suffering, you were going to end it.

Skip-

The guild hadn't seen or heard from Y/n in years. Even when Lisanna came home safe and sound, Y/n was still nowhere in sight.

It wasn't until the event with Tartaros, did they see Y/n again, and this time, Y/n was the enemy.

Y/n had apparently had requested for Zeref to turn her into a demon. An emotionless demon, so she wouldn't have to suffer from the loss of Lisanna.

When Lisanna saw Y/n, she was overjoyed. How could she not be? She was reunited with her twin at last!

An emotionless demon greeted her and attacked Fairy Tail alongside Tartaros. 

During the fight, however, Erza had fatally wounded her and she now lay on the ground soaked with her blood.

Seeing her sister in that state, Lisanna was devastated and ran towards her.

She dropped to her knees next to Y/n and grabbed her hand.

And to her surprise, y/n smiled at her. The gentle smile that could light up an entire room was now dim and was fading fast.

Y/n opened her mouth to speak for the last time, "Lis, remember...... I'll always be with you."

Before closing her eyes for the last time.
