Prologue.

Night Tokyo created a quite marvelous expression. The people have already left its streets and it was the time for demons to take the control over the city, whose destiny was to capture innocent people and through seducing them demons turned the innocents into the slaves of their desires, as some of important people like politicians, businessmen and the others, were very pleased to take part in seducing. However there were those who protected this corrupted world from the evil, having arrangements with the government, they were better known as monster hunters Taimanin. They protect this world by the cost of their lives. However some of part of them has been corrupted and turned into sex-slaves whose purpose was only in obeying their masters.

It was a peaceful night over the Tokyo and in some dark area of the city on the top of a high skyscraper were standing two men discussing something with each other.

"So do you really think that the seal was destroyed in Tokyo and not in the other place?" a young voice said with curiosity.

"According with the report from the headquarters the seal was extremely weakened. So we still have a feeble chance to restore it." the other person referred, but with a mechanical vibration in his voice.

"Can't Taimanin close the gates by themselves?" The young one couldn't stop his complaints.

"Did you visit the lessons of the demonic world history?" the other man sad as he saw a questioning expression on the face of his companion's face continued. "The elder demons had been defeated long before Taimanin appeared with their academy."

"So if we do this mission successfully, will I be able to become an instructor?"

The man with a mechanical voice turned at his young companion with interest and asked: "Do you want to become an instructor?"

"Ah? Oh sorry just rolled of the tongue, don't mention it."

Suddenly they both heard a strange sound and with nods went to investigate it. When both of them arrive to the place where those sounds were, they saw a combat scene. There were two women who fought with a bunch of demons and other creatures. The one was high and a bit muscular, she was tanned, had short blue hair. She was wearing a blue attire consisted from long tight high boots which looked like shoes on the base. Gloves which covered her arms till her elbows. And a suit which closed her body excludes her shoulders and a part of her thighs. She was fighting with a short blade.

The other woman was wearing a grey closed bodysuit and it was more closed than the suit of the other woman. She had black hair which was tied in a ponytail. Instead of her partner she was fighting with a bow.

"So, they're Taimanin, as I think." the first person said.

"Indeed, but I don't know who they are." the other one said to his companion.

"Let me see" said the boy as he got his hand into his pocket and took a small book and then started to flip through it. "Well, the one with a bow is Yabashi Ibiki, and the other with a blade is Ren Ikenami." He took away the book and put his hand onto the hilt of his sword which was on his back and was about to take it out, but at the same time he was stopped by a hand on his shoulder and then the mechanical voice said:

"Calm down boy!" and pointed at the fighters. "Firstly, they are about to win, secondly, they're fighting just an ordinary demons so they can handle it, and thirdly, it's not the time for us to show up and tell everything."

"But still!"

"If you want we can stay here and watch the results of the battle and if they somehow lose or something goes wrong you'll help them".

For some period of time they were watching the fight. The person without a mechanical voice was watching at the tanned girl breathlessly and amused how she was killing her enemies. She had a grace and her own style. As he admitted they had a perfect teamwork, combining close with distant combats. However the battle was finished quickly and with a sigh that he won't see the perfect skills of the huntress with the sword, but at the same time he felt relieved him, knowing that the beautiful girls were safe and sound in their own way.

"Well it's time for us to return Pavel" the man said to the boy who was watching at the girls. "We've lost enough time watching their battle.

"Fine, captain Tereshkov. Let's go, soon I'll become acquaint with them." Pavel said to the captain and they jumped off from the skyscraper.
