Four years ago.
Suddenly, «The Instructional» school was destroyed within one night by the evil fire spirit.
Inside the blaze, the boy snatched the ring sealed by the spirit of darkness and fled outside the facility. He, who was raised as a tool of destruction and slaughter, continued to wander aimlessly through the barren land.
And then, a few weeks have passed. In the remote city where he ventured, the boy contacted the border faction «Murder», a secret organization.
Without a sense of justice and knowing there was no other way to live other than through his fighting skills, he was unable to find any other choice.
They mocked the boys who came to their hideout with hair that had grown as long as possible and a tattered appearance.
What can such a child do, they say. But once their guards were beaten in an instant, their judgment towards him changed.
"I will accept any job. Price is..."
The gift he was looking for from «Murder» was one book. A book sealed by order of «Divine Ritual Obsession», a forbidden text, «Key of Edith».
The job he received instead was the strongest 'Killing Spirit Contractor' on the continent, «Blue» Palace Witch. And now, that boy, Kaizo is blending in at night in the witch's courtyard.
Suburbs of the imperial capital city. The grounds are large, but as home to the former number one «Numbers» that has been given the title of nobility, it is simple.
Let alone the spirit protecting the gate, not even a single servant was in sight, even though he already knew this from the information he had received.
The time Aidenwyth would return from the royal palace was getting closer. Shrouded in darkness, Kaizo touches the ring he's hiding behind his jacket. He caressed the words written on his outer edge in tongues.
(If this goes well, I can set him free.)
The one sealed inside the ring was the dark spirit girl. The girl who had given human emotions to the person who had become an empty tool in the training facility.
Giving emotion to Kaizo, who was supposed to be a tool, angered the instructors, causing him to be forcefully sealed again.
Although he had managed to steal the ring during the opportunity created by the destruction of the Instructional School, Kaizo did not know how to unseal it. Moreover, the instructors who knew how to unseal had all been killed by that «Evil Flame Spirit».
(But if I can get «Key of Edith», then I can definitely meet him again!)
He would kill the strongest Spirit Contractor in the continent in order to regain his smile. He had yet to undertake a murder mission, but he was sure it was something he would succeed in.
The sound of a horse-drawn carriage coming from the road. Kaizo heard it with his amazing hearing ability.
(This mission will be decided with the first attack. If I miss, I die.)
This was the iron rule when a non-elementalist fought with an elementalist. It seems that all the attempted assassinations against «Blue» Palace Magicians so far have failed.
The group «Killer» did not tell him what happened to those who failed. Not that he really wanted to know, but he didn't care.
Coach arrives at the gate. Kaizo covered the bottom of his face with a black cloth and unsheathed the twin swords on his waist.
Special short sword forged from spirit crystal, items he received at «Instructional» School. They have no inscriptions. It was actually not designed for combat but rather a twin sword intended to be used in the sword style ritual of the holy maiden.
However, giving divine power to his sword would also allow him to cut through spirits so that it was convenient for missions. Even so, there is no comparison in performance with the elementalist's «Elemental Aero».
The carriage door opened and a blonde-haired gray woman came out. Kaizo moved his entire muscle to action and darted out of the darkness. It leaves no room for reaction.
He closed the distance in an instant and slashed towards the woman's neck. He felt a loud bang with his hand. The twin blades of the sword had stopped in midair.
"Oh, you're different from the others." Clad in a gray dress, the beautiful woman said and smiled bewitchingly. In his hand was a thick book. The book had stopped the twin swords.
Shivers flowed down his back. It was something that should have been missing from him, an instinctive fear. Those bottomless gray eyes pierced through Kaizo.
(This man is.).
A monster, the word floated on his head.
He pulled out his twin swords and slipped into the darkness. Fighting more than this will be meaningless. Seeing that he had not dropped it in one strike, he had to wait for the time until the next opportunity.
"Geez, do you think you can escape after aiming at the witch's neck?"
«The Blue» Palace Witch smiled like she was enjoying herself and stretched out her hand. In an instant, a wisp of rebellious darkness was born from thin air.
(Is that a demon spirit!?)
They have different spirit structures and consequently cannot be controlled by humans. The one who can control them is, only «Blue» Palace Magicians are perverted.
A lump of darkness wrapped around his arm and formed a trembling sword. Even if he was not a Spirit Contractor, he could feel it with his skin. The one in front of his eyes was a top grade demon spirit. It was probably the same rank as Alicia, more or less the same.
(Although he is a retired spirit knight, he is contracted by a spirit of this caliber!)
He had heard it, but even though it was right in front of him, it was unbelievable. Normally, the abilities of a princess maiden reached their peak from the age of ten to the early twenties, and they would only weaken after that.
The Spirit Contractors who had lost their power would retire, marry high-hered nobles, and pass their power on to their daughters.
If it was true that he fought during the Vinral War, then his strength should have weakened a long time ago.
A sharp glint split the air.
(Very fast!)
He barely reacted by using his instincts, but the sword grazed him. The cloth on the bottom of his face was cut off and fell gently to the ground.
"Oh, pretty sweet girl," muttered, the sharp gray eyes widened slightly.
"I'm not a girl."
Kaizo spoke for the first time. He could not escape the reach of his opponent's sword. He would only be killed when he retreated.
(Then there is no other way but to solve it yourself.)
Kaizo prepared his twin swords and stared back into the eyes of the magician eagle, "I have come to kill «The Witch of Blue» Palace."
He immediately kicked the ground and closed the distance. The slash of god speed was aimed at the witch's throat, but before that. The figure of the witch swayed.
"Amplete Sword Arts, First Form, «Vegu» Lightning Flashes."
Aidenwyth's sword pierced through Kaizo's stomach.
