She was fed up. That was the only reason she could find to justify what she did.
Anybody that could appreciate the horror of seeing blood all around a person's decapitated body would think that whoever had committed such an action was definitely a monster.
It was a pity she didn't think that way.
For her, it was something that had to be done, sooner or later. She couldn't tolerate anymore such an annoying human. Always bothering, thinking he was the center of the world. Making her life a 'nightmare' –as she put it- wasn't something she was willing to let slide.
Today she finally did it. She had finally got rid of the pest, the bloodsucker that didn't let her live happily with the only thing that made her life more bearable.
"Aaaaaaaaaaaaaaaaaaaaaahhhhhhhhhhhh!!!!!!!!!!"
She suddenly heard a scream, a familiar voice. She rushed to the source of the noise, to check what the hell had happened to make a person scream that loud. As soon as she approached him, he directed a deathly glare to her, his eyes a mixture of anger and fear.
"Why??... WHY?!?! I thought you had changed! I never thought you would be able to do that to him…TO US!!"
There he was, face -covered in tears, scared and totally freaked out, standing on the living room, while the corpse lied on the floor.
"I'm sorry Kouta, but it was something I couldn't avoid. You don't need to cry for such an insignificant thing."
The diclonius with no horns didn't seem to understand the immense pain she was causing him.
"How do you dare saying that?! He was our son!!!"
