A Special Klein of love

The plan and final fight

Recap
Kat left klein and jake because klein proposed. Now she is know as the Heartless boss killer.
6 month later.
I was getting ready to meet everyone for the last battle rally.
"Ok lady and gentleman we are only waiting for Heathcliff and then the meeting will start."
I see Kirito Asuna Haley Jake and Klein. They look great but sad. I decide that today is when I talk go one of them and that one was kirito.
After dad showed up we talked about the plan we agreed and then it was time.
I grab kiritos arm and then pulled him out.
"Hey who do you think you are."
"God kid you still you."
"And heartless talks."
"So that's what they call me now. God these name changes suck from beater to white ninja to Heartless."
"Wait Kat your the one you killed a group of boss by yourself. And wait Heartless saved klein and Jake and even me a couple of times it was you."
"Yep." I take off my mask and he sees the new me.

"What happened to you."
"I died my hair bought new armor and became the Heartless boss killer."
"And you cut us out you didn't respond to anyone's messages."
"We all thought you logged out and left us for dead."
"Look I am alive and sorry to let you guys down."
"Have you talked to him."
"Nope. I came close many times. But never and I won't we are almost there kirito then I get to go back to the real world and be the 24 year old I am and go to a bar but till then I am kat the heartless boss killer. Goodbye kirito see you tomorrow."
"Bye kit kat."
I watched as he left and I put back on my mass and walk away as I get a message from jake.
To Kat
Please come home its been 6 months I miss you. Klein misses you he said we have to be tough for you but I know that you are the Heartless boss killer and I know that you dont want to come home but please just come home and BTW your secret is safe with me.
Love jake.
To jake
Thanks jake but I just can't not now I really do love you guys but I have too many sercets and I will be fine alone help klein get over me
Good bye Jake
Love Kat.
I went to where I have been living for the last past 6 months and notice the picture I kept on the fire place it was of me klein and jake being really happy.
"See you miss them."
I turned around to see kirito.
"I do not I am heartless I don't have feelings."
"Kat you can be heartless as you want but you see those smiles in that picture they disappeared in those two without you and you don't get it you just watch them and make sure they are safe."
"I knew telling anyone would be a mistake like falling in love with that goofball and not knowing how to forget him."
"See..."
I was crying now.
"Leave now. I need sleep before the boss tomorrow that I am going to kill."
Along with heathcliff. That's what her plan was she knew he was the last boss and you could defeat him.
After kirito left she went to sleep.
The next day
I was walking when Jake ran up to her and started talking to her.
"Kat klein thinks your died please talk to him."
"No I am fine not starting drama."
"Fine. I knew you would leave me like the others."
"Jake....."
"No go back to being the quiet loner that you always been..."
"Goodbye jake."
"Goodbye Kat."
"Jake who you talking to." I heard klein call.
"Someone who doesn't  care anymore."
"What is that suppose to mean."
"Klein you are so blind almost always."
"What."
"Nothing let's get to the fight."
Then I here footsteps running up to me.
"Hello I am Klein."
He puts out his hand for me to shake but I keep walking.
"Wow you are heartless well if you dont mind me asking a favor I was wondering if you can help me find somebody. Her name is Kat and I haven't heard from her for like 6 months and if you find her please tell her I am sorry for whatever I did to make her leave and I want her home. I miss her too much."
I try to make my voice so it was unrecognizable " yeah sure I will help now I must be going."
We got to the main boss room and I see heathcliff opening the door. Here we go. I see the monster we must destroy.
We attack it and I see klein going to get hit I blocked the hit before it could hit him and then I saw that it was down to 1/4 of its health so I took out my charams and charged at it at the same time as dad.
It died and we were resting.
"Your health didn't even go close to yellow." I heard kirito yell at heathcliff
"Yes that is because I am a good fighter."
"Or it is because you are kayaba himself."
"Ohh we have a smart one here but where is your evidence."
"Right here." I stood up walking over to my father.
"And who might you be."
"The heartless boss killer."
"Or should I call you by your first name....."
"No not in front of them."
"Why not Katherine you were the one who abandoned them were you not. Take off your mask and show everyone who the heartless boss killer really is."
I do as he said and I see Klein's face which looks like he saw a ghost." Kat. Is that you."
I ignore him and look at kayaba.
"Fight me." I see everyone but kirito and me fall.
"Fight you but your an immortal object. My dear daughter."
"Kat is that ture your his daughter."
"You lied to us." "Actually only you and jake didn't know."
"What. How much of us was a lie."
"Kirito I am going to kill him you in. Only if he lets Haley fight too."
"Ohh and you need to lose your immortality."
"Only if you lose yours two."
"Let's go you good for nothing."
"Oh and wait I think you guys need so motivation." He walks over to where klein and asuna are and stabs both of them.
"Nooooooooooooo...." I yell running to klein.
"Kat I love you never forget that no matter what."
"Klein I love you too don't worry I will be dead soon I promise you won't be alone for long."
I give him a kiss and he kissed back and I give him a hug as he breaks apart.
"Goodbye klein."
"Kirito you ready to kill this bastard."
"Yep. keelah se'lai" mass effect reference.
We fought him until I felt a sword go through me and kirito.
I hurt.
"Why couldn't you have been a good daughter."
I began to black out when I saw klein it was a the little thing that ran through my head what would have happened if I said yes.
"Hey look its my beautiful wife."
"And my hansome husband."
I hear him giggle
"What?"
"I was thinking about what will happen when we get out of here."
Then it happened he died right in front of me.
I am not done yet.
My body was glowing and so was kirito I equipped kliens sword and stab him with it at the same time as kirito does with asuna sword.
After we killed heathcliff a game over sign comes over my head and I see klein.
"Klein."
"You died too."
"Yep."
"Hey why are you crying."
"Because I was stupid I didn't tell you about who I really was and I didn't say yes when I wanted to."
"What would you say if I proposed again."
"I would say yes."
"Wow to see my daughter fall in love makes me happy. Just so you know I did everything you asked and more. I will not be coming back I died a long time ago."
"Dad. Mom died and now you no one will get to see my wedding."
"I am sorry kitten."
"Bye dad."
End of Sao
I wake up and notice I am not dead.
"Klein kirito. Where are they."
"Hello miss sora you looking for someone."
"Yes Tsuboi Ryōtarō."
"Ah yes Mr. Ruōtarō. He is this way my dear."
I look through the door and see him.
"Tsuboi is that you."
"Kat come here."
"Nurse I will be in here with him."
I walk over to him and he pulls me in for a kiss.
"That is way better than in Sao."
"Right."
"How would you ms.Sora like to go on a date with me at the closes bar."
"After I find kirio asuna and Haley."
"Of course."
