The legendary Demon Slayer

Haicheng City is the Home of Legendary Demon slayer.

Long time ago, the god of death, "Kiyoshi Hansang" declared that the evil spirits can't be accepted in the Heaven's. But some of the evil spirits tried to enter in heaven's by force, so Lord Kiyoshi Hansang cursed all the evil spirits that they have to live in the human world for 500 years and if they make atonement of their sins by doing good works in these 500 years then they will be granted to enter in the Heaven. Otherwise they will have to live in the human world in their evil spirit form for eternity.

Some spirits performed good deeds to atone for their sins and granted the permission to cross the door of Heaven. But some spirits were not agreed with the decision of Lord Kiyoshi Hansang and they committed even more sins and as soon as their 500 years ended, their souls began to rot. After some time their souls took the form of demons which had no mind, brutal strength and magical powers. And they started to destroy the human world and devour the human souls.

Human population was reduced to half in just one year and the two major cities and one holy church took the control of the leftover humans. They built a huge wall around each of their cities and a poweful magical barrier with the help of most powerful mages.

These two cities are 'Haicheng City', 'Shiong City' and 'Holy Church of Lord Kiyoshi Kensho'.

Haicheng City is the Home of Legendary Demon slayers. The humans are trained in this city to kill the demons by their cursed weapons or by making a contract with a demon. While Shiong City is the home of powerful mages. They learn all types of magic under the guidance of great mage 'Han shu'. And the Holy Church is the home of 'Lord Kiyoshi Kensho' the god of life. There is a myth that 200 years ago there was a small shrine where Lord Kiyoshi Kensho's wife lived and they gave a birth to a boy but that boy and his mother disappeared long time ago. Now there is only church keepers and the sisters lives in that Church.

In the Haicheng City's Demon Slayer Academy,

Today is the admission day. All the students are gathered in the main training grounds. Some of them are from noble families but some of them are peasents. They are all around 13 to 16 years of age.

A man with a muscular body and blue hairs with his two senior students came out from the academy and stood up in the front of the group of students.

Then he look all the students with a serious expression on his face and said in a loud voice, "I'm Zuo Tenshen! Your home room teacher."

"I will teach all of you that how you can use your spiritual flexion to control cursed weapons and to tame the demon spirits."

Then he gazed a girl in the group of students and said while pointing his finger on her, "You!"

"Tell me. What is Spiritual Flexion?!"

That girl with pink hair and a pale white skin stood up and said, "Spiritual Flexion is a form of spirit energy. We can control the cursed weapons or tame the demon spirit by the strength of Spiritual Flexion."

Zuo Tenshen noded his head with a serious look and said, "Correct!"

"You can tame the demons by the strength of spiritual flexion!"

"But your spiritual flexion should be greater than the Beginner level 5 otherwise even the lower level demon also will devour your soul, if you have been tried to tame him."

"Now, all of you make a line and move to the hall of the academy!"

"Your spiritual flexion will be checked in there."

Then he left the training ground with his two senior students.

All the students were talking about spiritual flexion test with their friends.

Suddenly a voice came from that crowd, "How dare you?"

All the students gathered around making a round circle. A purple haired boy was standing at middle of that crowd with his two friends. He is looking very rich and a boy wearing an old and dusty clothes was on the ground in the front of that rich boy.

That rich boy scolded the peasent one in anger while kicking him, "How dare you to mess my shoes?"

The peasent one started bleeding.

One of those two boys who is around that rich one said with mocking the peasent, "You peasent!"

"You dare to mess the shoes of a nobel."

"He is Feng Shu. The young master of Feng clan and you messed his shoes!?"

"Now bent on your knees and clean it with your tongue."

Suddenly a voice came from the crowd, "Stop it!"

All the students looked in that direction and made a path towards that person. It was a boy with short and silky white hairs and he is so handsome and manly. He was also looking from a noble family because of his clean and good clothes.

The other friend of Feng Shu said while stepping his foot towards that boy's direction, "Who are you?!"

"You are also looking like a noble and yet dare to save a peasent."
