Chapter 1
Awakening

The sun shone bright upon Tokyo as 16-year-old Kiko Sakuraba woke up from his world of dreams that fateful day. Well, almost woken up that is.
"KIKO!!!"

"Huh? Are you an angel?"
"It's your mother, baka! Now wake up and get ready, I want everything perfect for everyone's first day of school."
Kiko groaned. It was the worst day in every year, the first day of school, how could he have forgotten?
"What did you say?"
"Nothing, oka-chan."
His eyes were open but his mind was still enclosed in his dreams. Every summer, since the big opening of his father's business, Kiko's family started moving, a lot. They're departure from Morioka was as far back as he can remember, even before his little brother was born. Because of this, he didn't have a chance to build lasting friendships.
He forced his brain up and dragged his heavy body into the bath. He closed his eyes as the water from the shower enveloped him.
Ever since his family started moving, he had been having weird dreams every night. It always had this girl in it, even though she wasn't always visible; her presence lingered everywhere in his dreams. The weirdest thing is, every time Kiko plunged to take a closer look at the girl, she always manages to vanish in a flash of light.
BANG!!!
Kiko's concentration was broken in his brothers' entire ruckus; enter his mother trying to calm them down.
"I'm leaving!" Kiko called out to his struggling family, trying to wrestle his younger brother into submission after eating breakfast, "I'll see you guys after school. Sayonara Oto-sama, Oka-sama."
"Be careful- GEROFF ME KAJI!!!- Kiko-chan!" his mother called out to him before leaving, "You don't know the streets well and if I get another letter saying that you've poisoned the school rabbits or anything-"
"Oka-sama, I've never poisoned the school rabbits before..."
"Great idea though!" his brothers Kaji and Ken chorused as Kiko left the house.
People always said Kiko had very warm beetle-black eyes, but would turn like a hawk's in crisis, contrary to his happy-go-lucky mouth. He had short locks that always seemed to fall back in place when disturbed. He had quite a permanent tan in combination with his smart face that made some girls swoon for him in his old schools. Not exactly the honor student, he was known for being one of the most notorious pranksters in the face of Japan. Once he even blew up the school's toilets. He wouldn't look at it, but he had a knack of keeping out of trouble and managing to be popular at the same time.
What use is it to be popular when you don't have any real friends? It'll be different this time, I just know it! I'll find her, I know she's here, and I can feel her presence! Kiko thought to himself Oto-sama can never make me leave again!
"Gatekeeper Mimi Relina Yagami!"
"Hai, Kacho!!!"
This is Mimi Yagami, 15, the pioneer Gatekeeper of the Task Force Team BLITZ, headed by Chief Forte Kobayakawa, a.k.a. the vice principal of Tokyo Polytechnic University. Mimi stood there before the chief in silence, not knowing what to do.
Mimi was one of those rare girls who had the look of someone who had grown so much in a short period of time but was really still a kid at heart. She had a clever face and brain that made up for all of her childishness, and intelligent blackish brown eyes. Her untidy hair sat on her head in two ponytails.
"Miss Yagami, we need you on the eastern street near the school," Chief Forte instructed her, "Invader activity seems to be strong from that area."
"Asameshi mae! I'm going."
And maybe be early for math class for once! Mimi silently thought to herself.
And as if destiny couldn't be any naughtier...
Déjà vu is a sensation wherein you think that you have experienced this particular situation before or a certain vent has been repeated for you again. In this story you our heroes will be experiencing several moments of déjà vu such as...
"You!" Kiko exclaimed as his and Mimi's eyes both met at the empty street, "I- I know you! I've seen you before!"
"So you do," Mimi raised an eyebrow at this and gave Kiko an exasperated smile, "And I really have to go right now, sir. Be seeing you!"

Mimi walked into a dark alley, being tailed closely by Kiko with unceasing determination. She broke into a run, trying to get away from what she saw as a crazed lunatic that was Kiko.
It's her! The girl in m dreams!
Oh no! This can't be happening! Doesn't this guy ever give up? I have to lose him before-
"Uh-oh-"
Mimi threw a piercing look at Kiko, who stood rooted on the spot openmouthed. Before them was an enormous iron-grey and black worm with a tie and a face, towering above the buildings.
"You shouldn't have followed!" Mimi snapped at him, "Stay there while I get rid of this pest!"
Mimi motioned something with her palms, as if drawing a circle in thin air.
"Open the Gate!!!" she shouted at the top of her voice; spirals of delicate yellow appeared before her.
She opened her backpack and revealed what appeared to be a purple mechanical crossbow. She took out a few missiles from a compartment attached to her leg and fitted them onto the crossbow.
"Arrow of Light!!" she yelled, releasing the arrow with pinpoint accuracy at the worm.
The arrow radiated with yellow light from the spirals as it hit the worm on its face. The worm thrashed about in anguish, hitting everything in sight, even Mimi. She rolled in the ground and landed beside Kiko, apparently unable to move.
"H-hey..." Kiko stuttered, "A-are you- OK?"
Mimi looked at Kiko acidly, clutching her ribs, that were apparently broken. She tried to get up (the worm was still thrashing about), but the pain from her side was so excruciating that she fell back down again.
"Go, save yourself," Mimi choked, "You won't live long if you stay here anyhow. That guy's gonna flatten you if you don't"
By instinct, Kiko stood up and picked up a metal pipe that was littered on the floor. He had been Kendo champion on his old schools after all, but then he had a feeling this wouldn't be any other Kendo match; this would be the difference between life and death. That thought was quickly replaced when he heard the girl in his dreams stir; whatever happens, he had to protect her.
As he positioned himself into a stance, he felt something on his grip. It was Mimi, supporting his hand. She had healed herself using her power. He looked at the worm and saw that the same spirals he saw with Mimi was now before him, only it was a cool shade of blue.
"Go," was Mimi's words.
He lunged forwards and hit the worm with all the force he could muster, his heart full of undying valor. Mimi was with him, supporting what little power she had left. Their forces were so strong that the pipe broke into a thousand pieces.
With a single earsplitting growl, the worm itself exploded into blue- green crystalline pieces.
Kiko stood there in disbelief, staring at the rain of crystals. The touch of triumph was so strong that he couldn't help but grin.
"YATA!!!" he managed to shout, leaping up into the air, "I did it!!"
But how did I do it? Was the question that bothered him.
Kiko then felt a cold hand on his shoulder.
"Come with me Gatekeeper."
