An eighteen-year-old boy is running down a set of wooden stairs eating an energy bar. The teen has brown hair in a pony tail, and wearing a private school uniform. He tripped and ran out the door of a small mansion that is in the middle of a field, with a black bat with four wings right behind him.
"Ah, I'm going to be late," said the teen checking his watch.
"I tried to get you up, Theo," said the bat.
"Shut up Kaivat," said Theo.
Theo and Kaivat stopped when they heard a trumpet playing.
"Aw, now I'm going to be late for sure," complained Theo.
"A Glassfang attack is a Glassfang attack," replied Kaivat.
Kaivat and Theo dashed to the source of the sound.
A black Bear fangire was attacking a young woman in an alley.
"Aw, the girl looks like she's about to cry," said the fangire.
"What a teddy bear needs a grown woman to hug," said Theo.
"Who are you," said the fangire as the women ran when he was distracted.
"Aw, it's just a weak fangire," said Kaivat.
"What is weak is an idiot and his pet bat," said the black Bear fangire.
"Say hello to the king of the underworld for me," said Theo taking Kaivat into his right hand.
"Bite," said Kaivat as he bit Theo's left hand.
White chains wrapped around Theo's waist and turned into a white Kiva belt. "Henshin," said Theo putting Kaivat on the belt upside down. A white aura covered Theo. When the aura vanished, he was covered in a Kiva armor with a white chest plate, black eyes, and two hell's gates, one normal one on his left leg and a different one on his right leg.
"Wait you're Kaiva, lord of the Glassfangs," whimpered the Fangire.
"No, I'm just a savior," said Theo charging the Fangire. He front kicked the Fangire, then punched him in the stomach.
"I'm out of here," wined the Fangire in a weak voice as he tried to run away.
"No you don't," said Kaivat as Theo pulled out a white wake up fuesle, put it into Kaivat's mouth, and pushed down once. "Wake Up One," said Kaivat.
Theo lifted up his right leg and its hell's gate opened up with four bat wings. The sky turned pitched black with a moon making a lunar ring. Theo jumped into the air and into the center of the lunar ring. He came down and hit the Fangire in the back, shattering it and leaving a four winged bat sign in the ground.
"Man Fangire are weak," said Theo turning back to normal.
"Theo, school," said Kaivat.
"Right," said Theo as he dashed to school.
When Theo got to school his teacher, Ms. Stanly, yelled at him.
"Theodore Pendragon you are thirty minutes late," she said.
"Yes ma'am," said Theo.
"For being late you get detention after school today," said Ms. Stanly.
"Yes ma'am," said Theo again. He then went to his seat in the back of the class. After school, Theo stayed after for detention writing a paper. "Here's my paper Ms. Stanly," he said turning in the paper.
"Thank you, Theodore."
Theo walked out the front door of the school when he bumped into a girl wearing the same school uniform. The girl was average sized and has red hair.
"Sorry," said the red head.
"No, it was my fault," said Theo.
"Ah, Theo."
"Christy, that you?"
"I got to get going," said Christy with a red face.
"By Christy," said Theo as Christy ran away. "Time to go home," he said as he walked away.
When Theo got home, he went up stairs to his study. The room was lined with trumpets and books on vampires. In a glass case was a trumpet with bats encrusted on it. Theo took out the trumpet and admired it.
"The Bloody Marry," said Kaivat flying through the window."Your parting gift from your mother before she died. I haven't seen you touch it in a while."
"Ya, I felt like playing it," said Theo. He then started to play deep jazz.
Then the Bloody Marry started to play a different song.
"It better not be another Fangire," said Theo running out of his study and out the front door.
A stain glass monster was attacking a couple in the park. The monster has fins all over its body and has a catfish for a head. On its forehead was a blue gem with a water drop emblem on it. Its whiskers moved like tentacles and stabbed the women in the neck. The women turned into multicolored dust. The cat fish monster was about to kill the man when Kaivat hit the monster in the head.
"Finally, a Glassfang," yelled Theo in excitement taking Kaivat into his right hand and having Kaivat bite his left hand. The Kaiva belt appeared and Theo said ", henshin." Theo put Kaivat on the belt. Theo turned into Kaiva.
"Lord Kaiva," said the Catfish Glassfang.
"My name is Kaiva, but I am no Lord," replied Theo.
"Then you are a thief," said the Catfish charging Kaiva.
"No, I'm not. I was given this title," replied Theo swipe kicking the Glassfang causing him to trip.
The Glassfang got up and made a trident from the water of a nearby fountain. He then charged Kaiva and slashed him with the trident. He then punched Kaiva in the jaw.
Kaiva fell backwards to the ground.
"Theo snap out of it," said Kaivat.
"Right, let's end this," said Theo. He took out his Wake Up fuesle and put it into Kaivat's mouth and pressed down twice.
"Wake Up Two," said Kaivat as the sky tuned black and a solar eclipse appeared.
"No way can a thief destroy me," said the Catfish Glassfang.
Theo crouched down and ripped off the chains of both of his hell's gates. His right one has four wings and his left has two. Theo puts his legs together and jumped into the air.
"Ha, Glassfang. You're lucky to see our Solar Moon Break," said Kaivat.
Theo came down hard on the Catfish Glassfang's chest. The Glassfang shattered and his soul flew off to Theo's house. Then a dragon's head popped up out of the ground and ate the soul. When the head closed its mouth, it went back under ground.
"Man, Theo, you must have been angry to use the Solar Moon Break," said Kaivat.
"Let's go home," said Theo in an angered voice as he turned back to normal.
Far away a white haired teen girl was watching the fight from the top of a building. "Some one is using Uncle's powers," she said.
"We better go tell the King," said a female blue colored version of Kaivat.
"No, let's kill him and take his head to Uncle, right, Kaiva-la," said the white haired girl.
"Yes, Mistress Guinevere," said Kaiva-la.
"Lady Guinevere," said an African American man in a blue leather outfit.
"Yes, Aqua Pawn," said Guinevere.
"Your uncle, his Majesty, is calling you," said Aqua Pawn.
"Let's go Kaiva-la," said Guinevere as she, Aqua Pawn, and Kaiva-la disappeared.
--Next time on Kaiva—
The Check Mate Five, the leaders of the Glassfangs, have a meeting.
Theo meets Guinevere.
The Glassfang hunters, the Lions Pride, make their move.
And Theo's connection to King is revealed.
