AC: Here's the prologue of Secret of the Null.
Kaijudo: Secret of the Null
Prologue: Monsters attack
It was all but a normal day in San Champion town. The town was in complete chaos when a strange portal opened in the sky. There were monsters that resemble the mythology and there is also dragons, etc. Everyone is running away of those monsters and the town had a lot of damage. The duelmasters of the Kaijudo temple were currently repelling them and fighting back. They were fighting the evolved creature sent by the Choten and his evolve serum. He controlled the creatures and he made them attacked the town to take control of it.
In an alley, girl was running away from one of the beast and nothing could save her. The duelmasters aren't numerous enough to stop it and they are also too far to notice her.
Meanwhile, in the portal that connected the earth and the Kaiju realm, another creature came out. He floated in the air and he looked around, witnessing the destruction. His cape was floating by the wind while he observed what was happening around.
"...What happen here?" Wondered the creature.
He then heard a scream and he looked at the source of it. He saw nothing but he knew at which direction it was. He flew at the direction of the scream and he then saw what it was. An evolve fire creature was about to threw fire at a little girl. The girl was against the wall of the alley and she couldn't escape the fire creature even if she tried. The fire creature opened his mouth and he prepared a fire ball in his mouth.
"Got to hurry." Said the creature. He flew as fast he could.
The fire creature threw the fire ball and the girl screamed when she saw it coming. She then heard an explosion.
"...Am I dead?" She asked.
"No...You are not." Said a masculine voice. The voice was echoing a little.
She opened her eyes and she saw a giant knight who had his cape spread in front of her and hid her vision from the fire creature. He let his cape go and it returned to his place.
He is 14 ft. tall. He has pale blue hairs like fire that disperse when it goes too far. His eyes are crystal blue and shine. He wears a pure white long cape covering all of his body except his armored mask to the bottom of his feet. She saw that under the cape, he wears crystal blue armor on all of his body that shined and reflected the light. His body is muscular. He was a giant knight.
"Let me take care of the fire creature." Said the knight. He turned at the direction of the fire creature when he looked at the sky and he saw 5 creatures of energy. "Hum...The Mystics." He whispered.
He moved his arms and pointed it at the creature. A part of his cape moved away when he raised his hand. He saw the creature throwing a fire ball and he used the cape to block the attack. He then concentrate energy in his hand and when he was about to attack, the evolved creature suddenly returned to normal.
"The Spell of Radiant Purification." Said the knight.
The creature he was about to banish was back to normal. The knight threw a blast of energy and he destroyed the creature that disappeared into flame, back to the kaiju realm.
The knight turned around and he looked at the girl. He then lost altitude and he landed on the ground. He looked at the girl.
"...Are you alright?" Asked the knight.
"..." The girl said nothing. She saw a giant knight with great power. She couldn't back away more than she could now. She then saw him walked at her direction. "...Don't c-come..."
"Relax...I am not here to hurt you. I wouldn't have rescued you if it was the case." Said the knight calmly. The girl looked at his eyes and she suddenly felt like he wasn't that much dangerous.
"..." She said nothing for a few seconds. He had a point there.
"So...Are you alright?" Asked the knight again a little worried.
"...I'm...fine...Well...Thank you for saving me. I thought I was a goner...What was that?" She asked.
"It would be long to explain everything to you. You don't have to worry thought...All the creatures are going to be soon sent back to their world and you'll be safe." Said the knight.
"That is good." Said the girl.
"Hum..." Did the knight who moved his hand by the side. The cape is now completely hiding the armor of the knight who looked at her.
"What are you?" Asked the girl.
"I am a creature coming from their world." Said the knight. "You are a human I assumed."
"Yes. I am...The name is Diane...Who are you?" Asked the girl who started to calm down when she saw the knight showing no intention of hurting her. She was also saying to herself that he saved her life, so she can trust him a little.
"I am...Y...Just call me Y. My name is far too much complicated to spell right." Said Y.
"That's a weird name...Just a letter...But...Okay. What are you doing here?" Asked Diane. "If it is not too much indiscreet."
"I was wondering what happen in our world so I came here." Said Y.
"..." Diane said nothing for a while.
"Diane...Let me offer you something." Said Y.
He moved his hand and he showed her a glove. She took it and she wondered what it is.
"This glove is useless for now...But if you are accepting. I'll show you what it is and how to use this glove." Said Y.
Diane looked at him and she said nothing. She opened her palm and Y putted the glove in her hand. She looked at it and she then wondered why she accepted it. She wondered if it was her curiosity that got the best of her. She also wondered what she got into.
