The song literally explains the personalities in Kira and how Depression and Suicide are trying to take control and presway  her into giving up on life.

Kira's POV

I still was a sobbing mess as I closed the door.

'Everyone hates me, I'm a burden, and I've killed so many,my crush is getting married and doesn't care about me now, and I've killed so many friends, protected ones who I found out don't care about me, my best friend's in a coma, I was beaten as a child, never loved by a parent, bullied, laughed at, a waste of space.So, why should they care if I die?'I thought, tears pouring down in a never ending river of tears.

'These tears represent my pain, sorrow, anger,mane love.And, this is the last time they're going to come out of my eyes.'I thought, the pain and anger welling up inside me and I punched my mirror.

Broken glass cascaded down into the sink and the floor.

"Kira?" Teito asked outside the bathroom door.

I didn't reply, I only stared into the broken mirror with my right hands knuckles bleeding from shattering the mirror.

When I stared into my reflection, all I saw was a monster.

Someone who needed to be stopped.

Right then and there.

"Kira, open up."Teito pleaded, a little panicked as he tried to open the door.

I moved like a puppet, picking up a long shard of glass that was about the length of a dagger.Slowly, I made cuts on my skin, deep and rigged.What was the point? I was about to die anyways.

"KIRA! PLEASE LET ME IN!!!"Tieto screamed, his voice cracking as the door was banged on loudly.

I once again ignored him and continued.

Once I ran out of room on my arms, I want to my legs.

'Teito, I know you don't really care, so stop acting.You truly think I'm a burden, dontcha? You want me gone, just like Nathan should, and Valar does, don't you? But, no more.I don't want thins, nor do I need it.I'm ending it.Here.'I thought, hollowly staring at the door.

"Kira, I'm kicking down the door in five seconds!"Teito shouted.

"One......"

Drip

"Two....."

Drip

"Three....."

Slice

"Four....."

Pour

"FIVE!"And with that, the door flew off its hinges.

Once Teito regained his balance, he looked up and his eyes were huge.Then, without warning, he threw up.

"Kira......"Teito whispered, wiping the saliva off his lip.

He was about 5 feet away.

"Kira, out the glass down."Teito said, slowly starting inch towards me.

I growled."No!!! Move another inch and I do it!"I shouted, positioning the glass so that it was pointed at my chest, not my heart.If I stabbed my heart, then the sin wouldn't go with me.

That froze him.

The look of territory still remained on his face, though.I have no idea if it was because of the personalities control on me was weakening or if it was how much blood that was covering me and the floor around me, but, I was feeling light headed, but I still stood strong.

"No! You want this, don't you?! You dont care if die! You think I'm a burden, a mess up, a fluke! You think I'm the one who caused all your pain and suffering as a child! But no more.You won't have to deal with me anymore.I won't be your burden to bare, I won't feel this pain and sorrow, I won't feel like I don't belong or as if no cares about me.This'll be the last time I cry."I said, getting prepared for the blow I was about to make.

"This will be the last breath I take, alive."I said, taking one last breath, and plunging the glass toward my chest.

I coughed up blood and my grip loosened off of the glass and i fell backwards.More blood soaked my shirt as it spread.

"KIRA!!!!"Teito shrieked, running over to my side.

He knelt down next to me.

And the last thing I heard or saw, was Teito.And his worried expression as sirens rang out.

Valar's POV (of course I'm not gonna end the book with a cliffy like that.)

"Carla,I want the truth; what did you do to my letter on my desk?"I growled, glaring at her.

She was filing her nails, sitting on the bathroom counter with a bored expression.

"Oh, nothing much,Just that you didn't want her at the wedding, that you hated her, that you didn't love her and was abandoning her, and that she had Teito and Dina."Carala said, still in a bored voice as she continued to file her nails.

"YOU BITCH!!! HOW DARE YOU?! DO YOU NOT KNOW WHAT KIRA HAS GONE THROUGH?!"I screamed, hot tears forming in my eyes.

"Whoopie do, she was trapped in a virtual game for 2 years, so what? So we're you and you're perfectly fine."Carla said.

"No.She killed people in the game, that burden is shown clearly.The burden of both protecting your friends and killing others to do so it too hard to bare.Yet, she managed to,When she was younger, her parents were very abusive. They whipped her, slapped her, and even tried killing her multiple times.The only reason I didn't tell was because Kira would always smile, smile through the pain, and say she was fine that I didn't need to worry.

"But, I did need to worry because she started cutting when she was 9, do you know how young that is? She was in a horrible Foster care as everyone beat her up since she was one of the only girls, and that she was small and weak.Even when she was 8, bullies tormented her.They cursed her, spat in her, stoned her, and even sometimes cut or stabbed her for fun.One time, I caught a bully scratching her arms really hard, making them bleed lots.

"And, when she was 11, she committed suicide.The only reason that she survived was because I had convinced her not to and because I admitted I loved her. She ended up still falling but I saved her.But not even that was enough as she killed her families guards to escape them.

"And if you are saying that it's not big deal, THEN GO THROUGH WHAT SHE WENT THROUGH!!! ALONE!!!!! SHE DID ALL OF IT ALONE, NOT WANTING TO GET ANYONE CAUGHT UP IN IT AND HURT SO SHE KEPT ALL THESE FEELINGS TO HERSELF!!!! Why don't you try committing suicide? Or cutting? Or running away from abusive parents who used you as a slave? She went through all of that and is still alive today!

"And here you come along, trying to get her in more and deeper depression! And to tell her that one of her closet friends who was with her through all of that hates her and doesn't want her at his wedding is horrific, I wouldn't be surprised if she even started to do drugs along with the cutting!You make me sick."I snarled, spitting on her.

Her face was pale with terroir and fear.She gulped.

"A-she really went through all of that?"Carla said, out of breath.

"Yes! And she lived, because of her friends! But now, with Dina in a coma and me 'hating her', and Teito probably having to work her companies, she's completely alone and doing who knows what!"I shouted, the hot tears starting to pour down.

Suddenly, my phone started to ring.

I quickly whipped away my tears and pulled my phone out of my pocket.

"Yes?"I asked as calmly as I could, although my breath was still a little uneven.

"V-Valar!!!! I-It...........I-it-"Teito couldn't finish, he was sobbing and hyperventilating at the same time, making it difficult for anyone to understand what was being said.

"Calm down, what's wrong, you seemed panicked."I said.

"I-IT'S KIRA!!! She committed suicide! They don't know if she'll survived she's lost too much blood and her wounds are too deep!"Teito finally managed to shout into the phone.

And in that instant, I dropped my phone, causing it to shatter.

"What is it?"Carla asked.

I turned around to face her, true terror and bafflement all over my face.

"I-it's Kira.She committed suicide again.And she might not survive."I barely managed to bring the words out of my mouth.
