Sorrow 

Author POV
Y/n was feeling hatred to the girl. With all the hatred she felt. She turned to a demon. Uncontrollable by any kind. Valerie smirked. Yannie widen her eyes, but not in surprise, in fear.

She fears Y/n will lose herself.
She fears Y/n will join her older sister.
And most of all..
She fears of losing her.

All of her life. She cared greatly for her sister that Valerie never could. Valerie was always jealous of how much love Yannie shows towards Y/n. Its just the same love Yannie shows to her. But she never accepted it. All she wants is Power. To be unstoppable. And most of all.. To be a God.

Her sister said that having a power like that is uncontrollable. Corrupted even. No person or being can consume a great power.

The three sisters shares a great bond. But one broke it. Feeling that she wants to surpass them. That's why she wants them killed. For she can only have it for herself. But, she will never have it. For the Love of sisters is stronger.

Y/n POV
I feel all the hatred inside of me emerge. Want to control me. I really wanna kill her. Why.. Why would she do this? She was supposed to protect us! Dark aura surrounds me. Valerie chuckles. "Feel the Demon Y/n! Feel it! And set it free!" Valerie shouted. "NO! No Y/n! Control it! You have much more power you can ever imagine! Please!" Yannie begged. I tried to control it. But its too late. I have to. I need to! Then suddenly. I fainted.

Yannie's POV
Y/n fainted. Making the dark aura disappear. "Oh well. She set it free. I should kill her now" Valerie said summoning her dagger. I widen my eyes. "NO!" My voice boomed and I pulled my arm.

I don't goddamn care if I hurt it or not. Just as long Y/n is safe.

I stood up and ran to Y/n. But Valerie cut my cheeks so deep. I grunted but I grabbed Y/n's wrist and teleported to my house.

After I cleaned her up and changed her clothes. I set her to bed. I sat in her bed and looked at her. She really grew. My little goofball is all grown up. But I frowned. I should have left her. I should be protecting her. Its all my fault. It really is. If only I was a good sister this shouldn't have happened. I teared up.
