红颜薄命: Cursed Beauty (Yandere!KNY x F!Reader)

Who is Y/N?

You are determined.

After the trauma you experienced at a young age, you become a very fearful yet determined girl. You're very cautious of everything but you have the goal of becoming powerful so you'll never have to experience that pain again. 

You are caring.

You help those in need of help and you're unable deny help to those in trouble. You hold an especially soft spot for those who appear weak. That appearance of weakness reminds you of your former self and the desire to help them is increased.

You are grateful.

As time goes on, you meet others and make friends. With those you are comfortable with you can be energetic and affectionate. You never forget about those that have helped you. Though you still keep your distance, you appreciate the friendship and relationships you form.

Once you grow older and become accustomed to others, you become more secure and confident in yourself as your skills improve.

You are powerful.

Eventually, you become so confident and secure in yourself that you feel like even if you were to show your face, nothing bad could happen to you anyway. Mind you, at this point you believe that it's the nature of man that your mother was afraid of rather than a literal curse.

You are ignorant.

Ignorant people make mistakes.

Because you feel so secure and confident in your abilities, you end up making one of the most dangerous decisions of your life. Still clueless to the sinister curse that manifests in those around you, your confidence continues to grow as do your abilities.

You are conceited.

When your mask breaks, your confidence grows to the point of being conceited and cocky. At this point you're a pillar and the first to gain control of the see-through world as well as the first pillar with a Demon Slayer Mark. You act as if you're untouchable.

You are insecure.

However, deep down, this overconfidence has been set to mask your deep rooted insecurity of never being strong enough. Conceited people always overcompensate to try and make up for what they believe they lack. Because of this deep insecurity, you secretly begin to take pride in harming others. You become slightly sadistic because it makes you feel powerful and if you're powerful, you can't be harmed.

You are troubled.

After finding out about the curse, you are fooled by false invincibility that you are not fearful of this revelation. Instead, you find it troublesome. Believing that you're the most powerful pillar, you begin to see the other demon slayers as nuisances fueling your desire to avoid them and just get rid of the curse.

You are flawed.

Unfortunately, you are humbled when you come across the King of Demons. None of your abilities could ever top the experienced, 1000+ year old demon. Your ego and confidence was stabbed at by Muzan so you react with rage to hide your helplessness in the face of the Demon Progenitor.

You are sadistic.

Now when you become a demon, all your memories are gone. However, those feelings and emotions from when you're human remain. In fact, a demon's human emotions become amplified after they turn. If you were only a little sadistic as a human, you're a pure sadist after you turn.

This sadism shows when you allow Akaza to be tortured. You feel satisfaction and it's also a form of revenge as you subconsciously remember the time he had nearly killed your comrade.

You are fearful.

When the Demon Slayers infiltrate the Infinity Fortress, you feel the need to escape. However, without the protection of Muzan, your confidence wavers. Fearful of the demon slayers and because you dislike the demons, your only goal is to escape both parties.

You are manipulative.

You also start to get more confidence back now that Muzan, the demon that originally defeated you, is so willing to concede and do what you desire. Although you don't remember the event, your subconscious takes pride in being able to control your superior.

Unfortunately, your confidence is based only on your ability to manipulate Muzan and your deep insecurity of not being strong enough is amplified in your demon state. You are still very aware that you are not the strongest demon and that there are those that rank above you. Because you're so absorbed in needing to be the strongest, you are bothered by the hierarchy of the Upper Moons. In your eyes they are not protectors nor allies, they are nuisances.

Humans are crafted by their environment. All humans are flawed and no one reacts the same to trauma.

As life goes on, change is inevitable. Whether it's for the good or bad, people change.

No matter how admirable a character is, even protagonists can become villains.
