I decided to make a little song fic for Zero...And I decided to make him go yandere on Yuuki :3 Song is Saw and Pendulum by Miku Hatsune.

For your sake, for my sake

In order for me to tell you my true feelings

I will love you, I will support you

I will SAVE you

The sad thing about your body is

Its weak, fragile, and breaks apart into pieces

The only certain thing that kept me satisfied

was the fact that you

belong to ME

I couldn't hold back my love for you

I wanted it so much I broke you

This strong and intense heart I captured

will never LEAVE from me

The feelings you promised me

Are slowly rusting

I wanted to control you, I want to bind you

If I cant have that, then damage me

"Kaname-sama!" There it was. That annoying cry. That was all Zero heard. Everyday. Freaking. Day. He watched as Yuuki ran over to the man, not bothering to do anything. 'You know I love and yet you continue to tease me like this...' He thought.

Those feelings flowing inside my body

your laughter I hear, deep in my heart

is a voice I can no longer

I swore to myself tomorrow

Ah...

Zero was beyond jealous. He was angry and hurt at the same time. Though his stoic face gave away nothing. 'Do you prefer that monster over me?' He said he would support Yuuki's love for Kaname. But...that was a promise he could not keep.

The faint breathing noise coming from the darkness

converges my reasoning into one place

Even if my love is a sin

I will no longer cry over it

I will keep my head down and my voice quiet

I will cover my ears and etch the flow of time

There is nothing for me to fear

I am only going to share this sorrow

Zero sat on his bed, thinking. Night had fallen. 'Yes, I'll do it. If can't have her then...No one can.' He turned over his resolve made. Tomorrow was a day off from school, and the Chairman would be gone. Perfect.

I cant go back, I cant go home

Whats left is this warmness

If that's the shape of my love

then I wont REGRET it

This feeling I'm holding strongly

I couldn't hide it, I want it more and more

this dull feeling of heaviness in my arm

I would be lying if I said I have forgotten it

Are you shaking, that body of yours?

I took everything that was dear to me and linked them together

like a chain

and tightly closed the door

Hey...

"Hey Yuuki..." Zero walked towards the girl, who was on her way to town about to leave. "Yes, Zero-kun? Is there something wrong?" She turned towards him.

He held his Bloody Rose held behind his back.

The feelings you promised me

are slowly rusting

I want to control you, I want to bind you

if I cant have that, then damage me

He would have no regrets. Zero pointed the gun at her. Her eyes widened. "Zero-kun, what are you-"

She was promptly silenced by the sound of a gunshot.

This sentimental feeling flowing out of my body

When I woke up there was RED that stabbed the eyes

There are no mistakes

I gently caress your cold face.

"Well, looks like this is the way it had to be." He spoke to himself. "You were there for me...but, not entirely." He traced his finger over Yuuki's cold, blood-stained face. Blood got onto his finger, and he lifted it up to face and licked it, smiling. "If I can't have you, then no one can...I love you, Yuuki." He lifted her a little and then proceeded to hug Yuuki's dead body.
