Chapter 1: The Origin of the Devil

Heihachi Mishima looked how his father Jinpachi talked with a girl, a couple of years younger than him. It didn't matter for him, as he continued with his training.

"Heihachi." His father said as he was behind that girl "This is Kazumi Hachijo. She will be training with you from this day on."

Kazumi bowed her head "A pleasure to meet you, Heihachi-Kun."

Heihachi scoffed "Fine! But I won't go easy on you for being a woman! I won't be dragged down because of you!"

Kazumi smiled and nodded "Very well, maybe we can spar to know each other better." She suggested and Heihachi scoffed.

"Fine!" he got in pose and Kazumi did too.

Maybe he underestimated the abilities of Kazumi a bit too much, because after sending a quick punch, she ducked, grabbed his arm, twisting it and dropping him on his back.

Even Jinpachi was impressed, that once his surprise left him, he barked out a laugh "That was impressive Kazumi!"

Kazumi bowed her head "Thank you."

Heihachi who was still looking to the roof of the dojo, saw that Kazumi extended her hand to him "Are you okay, Heihachi-Kun?"

He accepted her hand and, in that moment, Heihachi decided.

He will marry her.

*Years Later*

Kazumi drank the tea that Heihachi made and hummed "It is a great tea, Heihachi-Kun. Thank you for inviting me."

Heihachi grinned "You're welcome, Kazumi! I bet that it is the best tea you ever tasted!" He bragged and Kazumi chuckled with a small smile.

"Say, why did you invite me all of the sudden?" Heihachi froze at the question "Not that I am not grateful, but it just surprised me."

"Ehm..." He gulped "Are you... single?"

He smacked his face at his question and Kazumi looked perplexed "Single? Like if I am having a romantic relationship with anyone?"

Heihachi gave a sharp nod, and she shook her head "Well, I am single."

Heihachi allowed himself to smile "And do you like someone?"

Kazumi nodded and Heihachi eyes closed "Is it... me?" He asked hopefully and he opened his eyes, feeling Kazumi's soft hands on his cheeks.

"Yes."

Heihachi felt his cheeks go warm, before he jumped and ran away in joy, screaming to everyone who could hear.

"SHE LOVES ME!"

*3 Years Later*

"Look Kazumi! He has spikey hair! That's a sign of intelligence in the Mishima Family!" Kazumi smiled seeing how Heihachi had their son, Kazuya.

Jinpachi laughed "Indeed! That is the trait of our family." He then turned to his son "Heihachi, had you proposed I suppose?"

Heihachi huffed and Kazumi giggled "He did. Now that Kazuya is born, I guess we can have the wedding now."

Jinpachi grinned "Excellent. I will get everything going then. You two don't worry about it."

Heihachi huffed "Senile old man, what makes you think that I wouldn't marry you after this."

Kazumi held his hand "Heihachi-Kun;"

Heihachi turned to her "Hm?"

"I love you."

Heihachi laughed "I love you too."

*5 Years Later*

As Jinpachi and Kazuya trained, Kazumi and Heihachi watched as they drank tea, Kazumi asked "Heihachi-Kun, what is your goal for the future?"

Heihachi grinned "What a silly question. It is the same from the day we met. Become a strong martial artist, stronger than my father to then make the Mishima Zaibatsu bigger. All for the good of our family."

Kazumi nodded with a small frown "Are you sure?"

Heihachi looked perplexed at that "About?"

"The zaibatsu by itself is big, if it becomes bigger, we might lose this lifestyle we have. The peaceful, happy life, replaced by other we might not be happy in it. Besides..."

"Who knows what harm it might cause."

Heihachi remained silent, watching his wife looking at their son laugh with Jinpachi. He hummed "Kazumi, I understand from where you are coming, but I would never do anything to put you and Kazuya in risk."

Kazumi nodded "Is that a promise?"

Heihachi hugged her and nodded "It is."

*6 Months later*

"Father! How did I do?" Kazuya asked after he finally managed to do his first electric wing god fist, destroying the dummy.

Heihachi laughed and ruffled his son hair "It was great! It reminds me when I did mine." he barked out a laugh "You are in a good road to become a strong fighter, my son!"

Kazuya blushed and nodded as he saw someone about to attack Heihachi "Father! Behind you!"

Heihachi turned around and blocked a strike from... "Kazumi?!"

Kazumi seemed dazed as she fell to her knees "H-Heihachi-Kun? Kazuya-Kun? Where am I?"

Heihachi went to hold her and turned to Kazuya "Go prepare some water to treat your mother."

Kazuya nodded quickly and ran away. Heihachi pressed his hand against Kazumi's forehead and hissed, her temperature being way too high.

Heihachi treated Kazumi alone in Hon-Maru. And one stormy night, as he was placing a wet towel on Kazumi's forehead, his wife's eyes snapped open... and they were different.

Full of hatred and malice, she jumped to her feet and hit Heihachi with a blow more powerful compared to the rest he received in his life.

Heihachi was sent flying to the wall of Hon-Maru. And as he climbed out of the debris, he saw how Kazumi... his dear Kazumi...

Turned into a devil in front of his eyes.

"Heihachi Mishima... My clan foresees how you attempt world domination, ruling with an iron fist... I will stop you!" Kazumi declared as she flew to fight Heihachi who just blocked.

"You! What have you done to Kazumi!" Heihachi demanded as he kept blocking, making Devil Kazumi hesitate for one second.

Heihachi grabbed her by the shoulders "Kazumi... what's happening!?"

Kazumi gulped "Heihachi-Kun... Forgive me." Kazumi cried "But my clan sent me to kill you..."

Heihachi frowned "Why? Then... all these years... Were fake..."

"No!" Kazumi said as she caressed his cheek "I love you Heihachi-Kun. That's why I ask you, take care of Kazuya, protect our son..."

"And kill me."

Heihachi shook as Kazumi caressed his cheek "It is for the best. If you don't... I will do something I will regret my whole life..."

Heihachi nodded "I don't want to... let's find a solution! Like we always do!"

Kazumi smiled sadly "I wish it was so easy this time... I do..." She lifted Heihachi's chin "Please my love..."

Heihachi nodded "I love you..." He held her neck with one hand and slowly, started to grip harder and harder.

Kazumi nodded as tears fell from her eyes "I love you too, Heihachi-Kun."

And with a sickening crack, Kazumi's limbs went stiff before they hanged loosely by her side.

Heihachi let a single tear fall down his face as he placed Kazumi slowly on the bed and closed her eyes. He closed his eyes and gritted his teeth...

"AAAAAAAAHHHHHHHHHHHH!" He let out a scream of pain, anger and impotence as the door was open.

"Father! Is everything okay!? What happened!?" Kazuya asked, hearing his scream.

"Kazuya." It would be so easy to lie. To tell him that the sickness killed Kazumi... but he wouldn't live with himself. If his son hates him... so, be it.

"I killed your mother."

Kazuya was punching his father, as they stood in the precipice. He was crying. And Heihachi... he was frowning.

"Kazuya. Listen to me."

"Shut up! You killed Mother!" Kazuya cried as he kicked Heihachi, who felt nothing.

"It was necessary. She asked for it."

"Lies!" Kazuya screamed and Heihachi started to get even more frustrated.

"Son, if you listen to me-"

"I'm not your son! You killed Mother!"

Heihachi growled and...

He front kicked Kazuya.

Kazuya landed some feet away and threw up. Heihachi's eyes widen and took a step forward "Kazuya..."

Kazuya tried to stand up but failed... Heihachi closed his eyes... He didn't want to... he doesn't want to think that his son might be possessed by the same thing that Kazumi was... but if he is...

Heihachi walked towards Kazuya and chopped him down, knocking him. He carefully picked him up bridal style and walked towards the edge.

Death... is a better destiny than being a devil.

He said that to himself, as he threw Kazuya off the cliff.

"Forgive me... Kazumi, Kazuya."

"TSUYA!"

Jinpachi was sent to the ground after Heihachi hit him with an electric. Heihachi then stomped his father on the chest, breaking some ribs and Jinpachi spit blood.

The Zaibatsu guards were pointing at Heihachi who glared at them "You now work for me." He declared as he walked towards the throne of his father.

Jinpachi tried to turn around and look at Heihachi "Heihachi... what are you doing... is killing your family... worth all this power?"

Heihachi stopped one step away from the throne and glared at his father over his shoulder "This... this is for my family. For what Kazumi wanted. Guards! Lock him down!" He barked at the end as the guards nodded.

The picked Jinpachi up who broke free and rushed to Heihachi with a scream.

And Heihachi headbutted him, cracking his skull.

As Jinpachi was dragged away, Heihachi sat down. Peace... he will achieve peace for her.
