There isn't any rhyme or reason as to why Kimura Kouki is a twisted thing. Since she could remember, she has always been popular for her cuteness and pretty face. Boys threw themselves at her and other girls were jealous of her. That's just how things are, it's law nearly. Eventually those things get to your head, and it shows with her. Spoiled by her parents, babied by her grandparents. Yeah, of course she's a brat.

That was until you came along and didn't instantly swoon to her charm. At first she didn't think much of it, but over time it slowly consumed her. Was there something unlikeable about her? Why weren't you a sheep in her flock? It just didn't make sense and it deeply unsettled her. Kouki found herself biting at her thumb's nail in visible frustration over your peculiarity.

When her class was picked for this year's Battle Royale, she found herself scared. Then she remembered exactly who she was, and what she's capable of. This little game simply gave her a more viable reason to be completely manipulative and cunning. It was her calling, nearly, and she found it all-time easy.

It was when she bumped into you during the second day, towards the evening, did she realize the extent of her contempt for you. Admittedly, Kouki was also aware of the chance that she was given. She had taken out three boys before she found herself in your 'care'... More like she wouldn't leave you alone, going along with the whole defenseless tactic so you'll take care of her.

Once you let your guard down, that's when she'll strike. Ripping and tearing away all of that nonchalance that you have for her. Maybe then you'll finally look at her and give Kouki the attention that she deserves in your final moments. Oh... How she'll enjoy it.
