Chapter I: Awakening

-Land of-Land of Light, 2018-

Zero's victorious battle over Kaiser Belial and his forces was not unheard of in the Land of Light. The entire population was aware of Zero's actions and were rejoicing at the wondrous news. Seven was proud of his son and his accomplishments, having understood he was no longer the naive Ultra he once was when he attempted to steal the Plasma Spark. If Seven hadn't stopped his son in time, he would have become a second Belial, and Seven shuddered at that thought alone.

"Oyaji! I've returned," Zero's voice drowned out Seven's inner thoughts.

"Welcome back my son," Seven said as everyone cheered upon seeing Zero.

The young Ultra had been traveling the world with a group he formed known as Ultimate Force Zero, comprised of beings Zero had met on his adventures. They had been ridding the universe of any remnants of Belial's forces since the battle. Seven did miss his son during the latter's travels and was glad to finally see him return home to the Land of Light.

"Zero, son of Seven, you have done a great service to the Land of Light by ridding us of Belial's presence," Father of Ultra said as he landed beside the duo.

"I only did what I had to do to protect the universe," Zero replied.

"Zero, it's time you become a guardian of a planet. As one of the strongest Ultras in the Land of Light, you have proven yourself worthy."

The young Ultra was stunned by those words. Him protect a planet? Of all people, they're letting him become a guardian?

Seven nudged his son in the ribs and Zero cleared his throat.

"I am honored to become the guardian of a planet. Which one will I be guarding?"

"One that your father guarded in the past," Father of Ultra revealed, turning to look at Seven.

"Earth."

"But why me? Surely Dyna or Tiga would be a better choice than a rookie like myself."

Zero's small protest elicted chuckles from the other Ultras. The Ultra hadn't been on M78 long enough to realize the veteran Ultras were still with their hosts. Then again, Father of Ultra did speak about getting them to return home.

"Dyna is still planet hopping with his crew, and don't even get me started on Tiga. Gaia seems content on remaining with his host, which leaves you as the next best candidate."

"Ah right..."

Damn that Dyna for planet hopping!

"I will leave right away," Zero bowed to the others but was pulled aside by Mother of Ultra.

"Zero, there's something I need you to do."

"What is it Mother?" he inquired, wondering why she wanted to speak to him in private.

Mother of Ultra glanced around to make sure there was no one around.

"I've detected faint traces of a new Ultra on Earth. If you find that person, bring them home to the Land of Light."

"Alright. I'll keep an eye out for the new Ultra."

"Thank you Zero."

Mebius came over to the younger Ultra and bumped him on the shoulder.

"So I heard you're assigned to protect Earth?" Mebius asked.

"Weren't you the last guardian of Earth?"

"I was, and no one has been selected after I left. I wasn't surprised when they chose you honestly, you deserve it after saving us from Belial."

Zero rubbed his head sheepishly and gave a nod to the older Ultra.

"Good luck. If you ever need help, don't forget you can always call me."

"Thanks Mebius."


-Japan, Tokyo-

"See you tomorrow Hayama-san!"

Mirai waved as her last patient for the day left the clinic. Closing the door quietly and locking it in place, Mirai took off her doctor's coat and hung it on the hook beside her jacket. Today's patients were many like usual but it wasn't anything she couldn't handle. It was flu season and many sought her for their annual flu shot. She lost count of how many shots she had given during the day.

All she wanted to do was go home and relax for the evening.

Slipping into her regular clothes for the day, Mirai locked up her clinic and headed towards her car. Along the way the pendant around her neck began to glow, something that's never happened before, prompting her to pull it out and study it.

She didn't know where the pendant came from, as it had been a gift from her mother before she passed away. The only thing her mother said was it was a key to finding her father, but Mirai never paid much attention to it. As far as she was concerned, her father doesn't exist. She was raised by her mother her entire life, and that was all she was going to acknowledge.

Pushing those thoughts out of her head, Mirai started her car and began the long drive home.


-Outer Space-

Rings of asteroids hurled past Zero as the Ultra flew towards his destination.

He couldn't believe he had been assigned to guard Earth.

The planet his father once guarded long ago.

A part of him was anxious to see what kind of planet Earth was, while the other was excited to be even given a planet to watch over. He turned to avoid a meteorite crashing into him and saw a familiar shadow up ahead.

"Yo Dyna!" he called out.

Ultraman Dyna heard the call and hovered in place, turning to see Zero flying towards him.

"Zero? What are you doing here?" the older Ultra asked.

"I should be asking you that! How long do you plan on planet hopping with that crew of yours? You and Gaia are both the same, refusing to return home. You know the others miss you a lot." Zero replied, smacking his friend lightly on the shoulder.

"Are you in a rush to get me back to the Land of Light or something?" Dyna chuckled, peering over Zero's shoulder when he spotted new figures coming their way.

Zero sensed it too and peered around.

"Ginga, Victory, X, why are you here? Even Orb is with you guys," Zero was perplexed to see so many Ultras in one spot.

"Defending the world from evil like we usually do," Ginga said with a chuckle.

"Knock it off Hikaru," Shou said from within Victory.

"Yeah yeah. Let's get back before the others wondered if we've been kidnapped."

Ginga and Victory flew off after bidding the others farewell.

"We were just patrolling the area to make sure no remnants of darkness remained," X said, indicating to him and Orb.

"Thank you for your hard work," Zero said jokingly.

Dyna chuckled at this and after a brief conversation, the group split up to go their separate ways. Zero focused his destination on Earth and saw a faint light glow in the distance, almost like a beacon calling his name. The only other time this happened was when he protected Emerana's planet, when a beacon called out to him as well. Perhaps this was another sign.

He headed in that direction.


Home.

The only place Mirai truly ever felt at peace.

Closing the door behind her, Mirai dropped her keys and purse on the chair, then went into her bedroom. The empty spot next to her bed was a faint reminder of the relationship she once had with her deceased boyfriend. She missed his warmth and the way he held her at night, whispering sweet things in her ear until she fell asleep against his chest.

They were due to be married.

Until that day arrived.

The day she lost everything.

Even now Mirai could still see everything clearly inside her mind like a movie.

It was just a regular day at work, one where she was about to head home to celebrate her birthday with Takumi and her mother. They had planned a lovely dinner at a small restaurant famous for their omakase. She was about to get into her car when a loud rumble tore through the streets, and people began screaming when they saw a giant monster emerge from the ground.

Mirai followed the crowd as they ran through the streets. That was when she saw her mother and Takumi trapped in his car, with the monster coming closer to where they were. She had screamed their names and began running towards them, but it was too late. The monster stomped down on the ground and crushed the car beneath its feet.

Her mother and Takumi died right before her eyes.

She screamed in anguish as a Ultraman suddenly appeared to fight off the monster, but she didn't care. That was the day she began to hate anything that had to do with the giants and the monsters they fought.

Sighing to herself, Mirai sat down on the futon and ran a hand gently through the sheets.

Sometimes she dreaded going to bed, mainly because she would dream of that day, but also because of a mysterious voice that's been whispering to her lately. She had no idea who or what it was, but the voice would whisper strange things to her. It was one of the reasons Mirai didn't want to go to bed.


Earth was such a beautiful planet.

Zero landed near a forest and looked around to make sure he hadn't been spotted. His timer began blinking at that moment, with Zero muttering to himself about the need to find a host. His father did explain that Earth's sun wasn't like the Plasma Spark back home, which meant it couldn't be converted into energy. He had to find a host or risk fading out of existence. The last time he ran out of energy, Ultraman Noa ended up reviving him alongside the Ultimate Aegis. This time he wouldn't have that luxury of being revived by an ancient Ultraman.

Hearing someone scream in terror, Zero looked over and saw a man being beaten by several robbers before proceeding to take his belongings. Normally Zero wouldn't even consider such a man for a host, but times were dire and the man looked like he was on the verge of death. Maybe he could find another host later or something, but the beeping on his timer was a constant reminder that he needed to make a decision soon.

"Guess I gotta break the rules this once," Zero said before merging with the man.

Once the merge was complete and he had control of the man's body, Zero slowly pushed himself up and felt around the pockets of the jacket he was wearing. Finding a card of some sorts, he yanked it out and looked at the writing.

"Kaneshiro Takuya," Zero said to himself.

So his host's name was Takuya.

After managing to figure out where his host lived, Zero proceeded to head in that direction.


Mirai woke up covered in a cold sweat, the same nightmare plaguing her dreams ever since the day of the incident. The pendant clinging against her damp skin was glowing again, prompting her to look down at it curiously. The pendant had been a gift from her late mother, on the day of her twenty-first birthday. Her mother never said anything about the origins of the necklace, only that her father planned on giving it to her the day she was born.

Glancing over to the clock on the wall, Mirai realized she was going to be late for her shift to work if she didn't get her butt out of the bed. Scrambling around the house while brushing her teeth, she barely managed to gulp down a piece of toast before running out of her apartment.

Once she arrived at the hospital, Mirai hurriedly changed into her white coat and began making her rounds around the floor.


Zero groaned as his host's body ached everywhere, even in places he thought wasn't possible. Humans sure were fragile beings if being knocked out caused this much damage to their bodies. Memories of last night were somewhat foggy as the Ultra slowly sat up in bed, the only thing he could remember was somehow finding the house his host lived in, before blacking out from the damage he had suffered.

Now that his body was finally adjusting to the planet, Zero knew his work had only begun. Mother of Ultra had entrusted him with finding a hidden Ultra here on Earth, but where would he even begin? The planet wasn't exactly small and humanity as a population was pretty large to begin with. Zero suddenly recalled the mysterious light he saw while in space, the light that guided him towards Earth like a beacon.

Could that be a sign of sorts?

Pushing himself out of bed and into the bathroom, Zero stood under the shower for a good while to gather his thoughts.

A bright light enveloped him at that moment and the Ultra covered his eyes briefly, then lowered his hand to find his father, Zoffy, Ace, Taro and several other Ultras standing before him. He knew what had happened, the others must have reached out to him telepathically.

"Oyaji? What's going on?" Zero asked in confusion.

"Zero there is something...we didn't tell you back on M78," Seven said while the others kept their solemn expressions.

"What's happening?"

"We know Mother of Ultra asked you to seek out a hidden Ultra on Earth," Taro said.

"What about it?" Zero frowned, even more perplexed than ever.

Zoffy exchanged a brief look with Seven.

"That Ultra is your sister," Seven revealed.

"Sister? Oyaji you're not making any sense. You never said I had any siblings! I thought I was your only child!"

Seven rested a hand on his son's shoulder to calm him down.

"Your sister was born in the Land of Light like you were, but all of us realized her birth would bring great disaster upon her life, so we hid her on Earth with a human female I trusted. We did it to protect her from Belial, because if he knew of her powers, he would surely try to take her."

"But Belial is dead. I defeated him at the Monster Graveyard," Zero countered as he struggled to keep his temper under control.

"Yes, which is the reason why it is finally safe to bring her back to the Land of Light. Her powers have begun lashing out and unless she realizes who she is, it will cause her great harm mentally and physically," Taro said.

"What is so special about my sister that Belial would want her for himself?"

The other Ultras shifted slightly.

"Your sister...she has the ability to take a Ultra's power and use it for herself. Imagine what Belial would do if he got hold of her. He could use her to take all our powers away and render us defenseless."

Now Zero was really perplexed.

"Ginga has that ability, Orb and Geed do as well, why is that such a big deal?"

"My son, Orb, Ginga and Geed merely borrow our powers to fight on the battlefield. Your sister doesn't just borrow our powers, she can claim it as her own and unless she wishes it, permanently keep our powers for herself."

Now it was clear to the young Ultra why his father had to keep his sister hidden away. The ability to take a Ultra's power was unheard of in the Land of Light, and if Belial had learned of her existence back then...Zero shuddered as he imagined what he would have done to her.

"Do you understand now why we had to hide her away?" Zoffy inquired, noticing Zero going quiet.

"Yes. I get it but why did you wait until now to tell me I have a sister?" Zero glared at his father accusingly.

"We couldn't risk Belial learning of her existence, and given your impulsive actions in the past, we were worried you would go charging off to find her."

Seven had a point.

"If you find her, bring her home to us so we may reunite as a family."

"What is her name?" Zero asked.

"Mirai. Hayama Mirai."


Mirai sneezed at that moment as she was just about to take a drink of water.

"Is someone talking about me?" she wondered, wiping her nose with a tissue.

"Mirai-san let's go out for lunch!" Ayame said, popping into her office with a grin.

"Sure. I'm due for a break," Mirai answered, stretching her arms above head.

The two girls grabbed their coats and headed out the door, they were barely a foot away from the hospital entrance when screams filled the air. Mirai scanned her surroundings and saw a giant monster emerge from a hole in the ground and begin rampaging around.

"What is that!" Ayame screamed in terror.

The doctor had no answer for her as the monster locked gazes with Mirai. She flinched when a voice mysteriously began speaking inside her mind.

I finally found you, daughter of Seven, join me and we'll raise the darkness together!

"Get out of my head!" Mirai shouted, hunching over and holding her hands over both ears.

"Look out!" Mirai vaguely heard Ayame scream.

Before the monster could reach down and grab her, a bright pillar of light blinded Mirai momentarily. When she opened her eyes again, she saw a giant fighting off the monster and immediately recognized him.

"Ultraman..."


Zero transformed just in time before the monster could grab a innocent human from the ground.

"Let's get this over with," he said and kicked the monster away from the girl.

The monster let out a roar as a voice telepathically called out to the Ultra.

Ultraman Zero, this does not concern you! Leave before I destroy you!

"I'd like to see you try," Zero scoffed, cocking his head to the side tauntingly.

Lunazela, destroy this Ultraman and bring me my prize!

The monster roared again and charged towards Zero, its horn glowing in preparation to unleash a charged attack of sorts. Unleashing his Sluggers at the beast, Zero grabbed it by the neck, narrowly avoiding being impaled by the horn while his Sluggers did a boomerang return, slicing through Lunazela's thick hide. Using its claws, Lunazela slashed at the Ultraman, making him release his hold around its neck.

Opening its mouth for a beam attack, Lunazela unleashed a blue stream of fire towards Zero. The Ultraman rolled to the side and quickly switched forms, knowing he had to defeat the monster before it could cause anymore damage.

"Strong Corona Zero!"

Gathering energy into his hands via his Ultimate Bracelet, Zero unleashed his signature attack against Lunazela.

"Garnate Buster!"


Mirai watched the entire battle unfold as the Ultraman engaged in combat with the monster that tried to kidnap her. Her entire body trembled in fright, as if she was witnessing that day all over again. Though the Ultraman was powerful, Mirai had a feeling the alien wasn't just some simple monster that can be beaten with a powerful attack. When the giant of light unleashed a powerful move on it, she saw the monster absorb the energy in the middle of its chest.

"Be careful!" she screamed.

As if having heard her screams, the Ultraman was distracted when he looked at her. This opening gave the alien a chance to fire a red beam at him, knocking him off balance and tumbling into several buildings behind.

"Zero!" Mirai shouted.

'Zero? How did I know his name is Zero?'

That beam attack seemed to knock the wind out of Zero and the alien charged up for a final attack.

"No!"

A strange device suddenly materialized on her hand and Mirai studied it briefly. The device resembled a bracer of sorts with a blue jewel in the center, and a voice in her head told her to raise it in the air.

Raising the same hand in the air, Mirai spun the jewel in the center and allowed the light to cover her body, then she pressed down on the same jewel and the bracer glowed brightly. A bright light swallowed her at that moment, and Mirai began freaking out when she realised she couldn't see what was going on with her body.

When the light faded away, Mirai was shocked to find herself transformed into a red-blue giantess.

"What the hell?" she said, looking down at her hands in shock.

You have finally embraced who you truly are.

"Who goes there!?" she demanded.

The same giantess she just transformed into emerged from the bright light.

I am Corona, your true heritage as a Ultrawoman has finally been revealed.

"What do you mean I'm a Ultrawoman? I'm a normal human being! I can't be...I can't be a Ultra!"

Hayama Mirai is your earthly identity, your true heritage is the daughter of Ultraseven, the sister of Ultraman Zero. When you were born, your father sent you away to Earth to protect you from Belial and his forces. Now that Belial has been defeated, your powers have awakened. I am thou, thou art I, we are two halves of a whole. I was merely sleeping within you, until you were ready to become who you were meant to be.

Mirai couldn't believe what was happening.

Of all the people, she was a Ultrawoman.

"So what's going to happen to me now?" she asked incredulously.

First we must defeat Lunazela, alongside our brother Zero, we are one of the strongest Ultras to ever be born. We have the ability to take a Ultra's power for ourselves and use it in battle.

"Take a Ultra's power?..."

I will explain more to you later. First we must defeat that alien before more harm can come to the people.

"How!? I can't fight!"

We are one, do not be afraid. You are an Ultra, fighting is in your blood. Let your senses guide you and you will be fine.


Zero was shocked to find a Ultrawoman standing before him when the light faded away. Could she be the one his father spoke of?

Her transformed state resembled his and Seven's to a certain degree, only she lacked the sluggers they had. Instead she had a bracelet-like device on her right hand that formed into a knuckle grip, leading Zero to wonder if that was what allowed her to take another Ultra's ability to use as her own.

She was also slightly shorter than he was.

"Are you alright Zero?" she asked, holding a hand out to him.

"I am. Are you my sister?" he grabbed her hand and straightened up.

"I am Corona," the other Ultra confirmed.

"Let's beat this guy together," Zero said.

Corona gave a nod and ran forward to unleash a kick to the alien's abdomen while Zero changed forms yet again.

"Luna Miracle Zero," his suit took on a blue-grey hue.

"Miracle Zero Slugger!"

He shot his hand forward and his Sluggers formed into three identical pairs, striking through Lunazela's hide in various places, causing the alien to roar in anger. Corona followed up with a upper cut to the chin, sending Lunazela flying upwards towards the sky.

"Wide Zero Shot!"

"Solarium Grenade!"

Zero's shot hit Lunazela first while Corona charged up a blast of energy between her hands, the unleashed it at the same spot her brother had hit.

The combined force of their attack was enough to disintegrate Lunazela as the alien disappeared in a burst of bright light.

Mirai had no idea how she did it, but somehow she managed to defeat the monster with Zero's help.

"Oh my god..." she breathed in shock.

"Corona?"

Her head turned to find Zero looking at her.

"S-Stay away!" she said frantically.

"What do you mean? You're my sister aren't you? I'm not going to hurt you," Zero tried to reassure.

"No! Stay away!" Mirai said, a bit more forcefully now that the shock of the battle wore away.

The bracelet around her right hand began glowing brightly at that point just as Mirai slapped Zero's hand away from her. Something happened at that moment and Mirai could feel a new power flow into her body. She lifted up her hand and saw a light flicker inside the bracelet, while Zero was suddenly forced back into his regular form.

"What the heck? I didn't change back," the Ultra said in confusion.

"What's going on!?" Mirai shrieked in alarm when her body changed into a form that suspiciously resembled Zero's Luna Miracle state.

"You...did you just..."

Not knowing what to do any longer, Mirai cancelled her transformation, leaving Zero with his basic form while he tried to stop her.

"Damn it, now I have to get my powers back from her."

Zero undid his transformation as well but it was already too late, his sister was gone from the area. Knowing he couldn't do anything unless she relinquished his Luna Miracle form back, the Ultra decided to contact his father and ask him for advice.


To be continued...
