Chapter 1: Obsidian Cavalier

Mephisto really disliked vampire, but not hate, in fact, she didn't have strong hate. However, her partner Lithel commented like "She hates them as I hate drugs". He usually repeated it few times in a singing tone when they hunted vampires. Yes, they're vampire hunters of an organization called "Teeth Of God's Hounds" (TOGH).

And now, they were doing an assignment – to finish a vampire who already killed three hunters of TOGH.

"Who give you that title, who will kill your fame?" The purple-eyed handsome man, Lithel smiled – he always put on a smiling face – and sang in a cheerful tone.

"Mephisto, make your damn partner shut the fuck up first!" their workmate shouted through the mini-communicator as if he would break down.

"I don't need your order." The black-haired girl replied coolly.

Lithel let out a little sigh. "Oh come on, poor Seth, you never learn how to sing and how to enjoy your life."

"There's no fuckin' relation between your fuckin' songs and to enjoy fuckin' life, you damn psycho!" the youth shouted as an angry lion. "Just shut the fuck up!"

"Five times to use bad words, boy, watch your mouth." Said Lithel.

"AAAHHHHH!"

Mephisto, the young hunter with oriental appearance, lowered the volume of her communicator silently. Lithel did so. No one could stand Seth's scream, even vampires. Lithel had asked the Boss to let Seth join the battle – "He didn't need to fight, only need to scream, vampire would run away." That's what Lithel said. Then Mephisto saw the Boss sighed deeply.

This joke is not funny. She murmured.

Back to now, the target's car was in the attack range. Mephisto drew her sword, murmured something softly – that was her spell, also the prayer.

"From the hellfire's arms

From the frozen air's wings

You are showing you glory

I am your sword for hunting

Even blood let me fall

Thorns cannot stop my steps

Dark cannot cover my eyes

If I lost the way

Bury me with only a name"

She let out a long breath, turned to her purple-eyed partner, said coolly, "Cover me." Then she jumped down.

From the top of a 9-floor high building.

Falling down, never stop.

And no one could stop her hunting sword.

Lithel watched Mephisto's figure becoming a smaller point gradually, finally made a crazily happy laugh. "Great, that's so great! Obsidian Cavalier, lift your sword high, you are the main character of this hunting night!"

"I said no."

"Why?"

"Why do I have to marry a woman I don't love?"

"Alexi, how can you…"

The woman's words were cut by an unexpected bang. The impact fell from the sky not only broke all the glasses, but also destroyed the front of the car. They got off the car as soon as they can, with curses like "what's the hell". When they saw the figure which stood on the car, they were both shocked.

It was a black-haired girl with bluish-black eyes, her slim body was like an elf. She held a long sword, there was a pattern of serpent deeply carved on the shinning blade. The black long robe with silver fal-lal that she wore was so familiar.

"I am the Hound of the God, hunt all the sins and swallow blood." She whispered softly, but loud enough for the two to hear. "Good night, and Goodbye, Mr. Alexi Laiho." She raised a cold smile, swinging her sword into Alexi's face!

"What the fuck?!" Alexi shouted, stepping back quickly.

"Missed one point." The black-haired hunter murmured.

Alexi clenched teeth, "You destroyed my car, you're gonna pay!"

"Whatever." She continued the attack as a killing machine never stopped. "Now face it, Alexi 'Wildchild' Laiho, face your beautiful doom day."

"Sounds funny. What's your damn name and title, crazy hunter?"

"Mephisto, No. 21, a.k.a Obsidian Cavalier."
