I DO NOT own Tekken. It belongs to Namco.

Prologue

A long time ago, the Underworld's demons invaded the human world. Though the Celestia's angels had came to the human's aid, the demons tore through their defenses despite the efforts to stop them. As years passed, the war destroyed most of the human civilization and the humans were on the brick of extinction.

Realizing the dire situation the humans are in, the elves of the Sundered Lands finally stepped in to intervene. With their uncanny ability to nullify hostile attacks and pinpointing the weaknesses of the demons, the elves forced the infernal beings to flee and sealed the gateway between the Underworld and human world, thus bringing the war to an end.

Bitter towards losing to the 'inferior lifeforms', as the elves sealed the gateway, the demons placed a curse upon the humans, promising that they will return with vengeance. To counter the curse, the angels bestow the humans a power that can suppress the evil before ascending back to Celestia. The elves remained in the human world for generations to come, helping with the human's recovery and making sure that the demons will never return again.

Centuries passed, the descendants of the humans eventually forgot the great war and the knowledge of the existence of the 'Elven guardians' slowly fade into history...

Present day Japan

"May, pack your bags! I'm taking you to stay at one of my friend's house for a few months," A male voice called out from the study downstairs. May emitted a sigh as she set down her favorite book 'Alice in Wonderland' on her bed. She knew that meant one thing: Her father is going to excavate another archaeological site without her. Again.

"But, father! You promised me that you would bring me along with you this time!"

Slow, heavy steps can be heard coming up the stairs towards the bedroom door and Satoru Tanaka, May's father, peered inside to look at the moody five-year-old girl with an apologetic smile on his face.

"I'm sorry, May. I have not forgotten that promise I made with you on my last trip. But the friend I want you to stay with this time needs your help. You can think of that as gaining a favor from me."

May could feel her other half, Alice stirring from within. She thought that it was strange, as Alice usually spent most the time sleeping inside her.

She decided that it wouldn't hurt to inquire more information from father. "What kind of help, Father?" May asked

Even though May kept a straight face, Satoru could tell that Alice is listening in, with the way his daughter's complete heterochromia eyes, one black and one light forest green, looked intensely at him.

"Well, my lady has a son the same age as you. He has a...simliar 'condition' like you but his other half doesn't play nice with everyone around him. So I decided to send you over to help her."

Satoru cocked his head as he asked carefully, "I will take you to another site if you can help my friend, so...are you willing to help me?"

"...All right."

"Great!" He said with a sincere smile as he took out a bag from May's closet to help her pack. "We'll be leaving in half an hour."

A few hours later, at Yakushima, May's POV

"Alice, why do you want me to help Jun Kazama?" I mumbled as father and I trekked through the dense forest, which turned a little eerie as it was getting dark. Alice had stopped me from saying no when father asked me for help back at the house.

There was a long uncomfortable pause as I waited stubbornly for Alice to answer my question and she finally spoke.

...May, I have my own reason for forcing you to accept our father's request...Trust me, you'll thank me when this is over.

That got me confused. What did she mean by that?

I wanted to question her again but was suddenly interrupted by a light tap on my shoulder.

"May, we are almost there." said father as he pointed to a light source not far off.
