Editing Seirei Tsukai no Blade Dance:Volume1 Chapter7 (section)

=== Part 1 ===

.....He remembered that he was taken into a black room.

A room like a prison cell without windows.

He recalled being taken by people in black, also on that day he met ''her'' for the first time—

It was eight years ago when the young boy became The Strongest Blade Dancer—Ren Ashbell.

Before that, he was at an orphanage.

It was no ordinary orphanage. It was a so called "Instructional School" of a town that didn't exist on any maps.

From every part of the continent, young girls with talents as an elementalist were gathered from orphanages or relief institutions, and received special training in the secret facility. Those who were raised there were exceptional assassins. The emotions of the girls were killed by the crazy education, and nothing but killing techniques using spirits were thoroughly drilled into them.

On that day eight years ago, a young boy who was taken in by the Instructional School was able to communicate with the spirits.

The Demon King's Reincarnation—called a miracle child by the training instructor, that young boy was trained with the highest priority.

He was subjected to assassination training of the highest caliber, as well as handing to him their treasured spirit, one of the most powerful Pillar Spirits.

Formerly, a sealed spirit because of the Demon King, the darkness spirit.

But, four years ago, a freak accident of unknown origin suddenly destroyed the Instructional School.

Thanks to the incident, the hideous truth of the Instructional School was brought to light, and the aristocrat faction in charge of the scheme was purged; its existence was erased from all the records of the Ordesia empire.

The young boy escaped with his contracted spirit.

Running away from his pursuers, he disguised himself as a girl. Originally the young boy had well equipped features; his voice had yet to break, and nobody thought that he was a boy.

Also, three years ago. The strongest blade dancer magnificently debuted.

Winning the Blade Dance, in order to fulfill ''her'' one and only Wish.

But, it was— ''something humans must never wish for''.
